Hinging on Design: Nest Cam IQ’s Hinge

Redistributed from Nest blog: https://nest.tech/hinging-on-design-nest-cam-iqs-hinge-22efb899ce76

In June, we introduced the Nest Cam IQ. Well-proportioned and seamless, it brings out the best in Nest hardware design and engineering innovation. When we started design work, we looked at it as a wide-open opportunity to define the new generation of indoor camera. Our objective was to design an evolution of the existing Nest Indoor Camera and make it feel even more Nesty.

To us, evolution meant keeping the aspects that people love and adding values that make their experience better, with a friendlier and more approachable design that blends well into homes.

After an in-depth evaluation of our own indoor camera and user trends, one of our top insights was that offering huge hinge articulation was one of the key differentiators that made our Indoor Cam so successful in the market. Camera users want this range of articulation to handle all the ways they use the camera, where they place it and what they want to see from each location.

With this learning in mind, we explored ways to make it even better by introducing more integrated and balanced design with the new generation.

Design Choices

One of the first things you notice when setting up your Nest Cam IQ is that the power cable plugs into the base, not the camera head, allowing for clean routing away from your device. We challenged ourselves to have the cable routing go through the hinge mechanism and have the power plug into the base for seamless look and solid stability. If we could do that, we’d create one of the slimmest, most versatile, and most elegant hinges on on any consumer device.

This was an important design choice we made in building Nest Cam IQ, but it also brought major design and engineering implications. How do power and data signals get from the base to the head through a tiny hinge? And how can the hinge move through such a large range of motion without any wires ever being seen?

We explored several mechanism designs to solve these problems. Ball joints were a natural design choice with our device form factor, but we quickly realized we couldn’t achieve the range of motion we wanted without pinching and exposing wires. Pogo pins, spring contacts, and flexible goosenecks are other common ways to route electrical signals through a moving joint, but each of these concepts either lacks the full range of motion we desired, or was aesthetically unacceptable.

Flexible printed circuits (FPCs) are another common technology to route electrical signals through tight spaces. However, FPCs are thin and flat, which means they are suitable for bending in one direction. Since our hinge swivels up and down, as well as left and right, we found our FPC concepts cracked internally with this combination of bending and twisting.

Finding design solutions — and more challenges

Eventually, we concluded that we needed to pass wires through the axle of the hinge to hide them through the full ± 90 degree range of motion. However, routing a concealed wire through the side of the hinge would surely cause the total width of design to grow. To get around this size constraint, we came up with a custom wire bundle that is round going through the hinge, but flat when it exists the hinge axle, saving precious space. This custom multi-section wire bundle gives us the best of both worlds — a slim external hinge profile and hidden wires through the full range of motion.

Wire routing wasn’t our only challenge. The head of the Nest Cam IQ is made of a thick plastic shell, and packs a huge speaker, multiple metal chassis and heat spreaders, and a 4K camera module. In total, the head weighs over 200 grams. All the technology packed into the head created big challenges for the hinge. How could we hold a heavy, densely packed head in place with the friction from such a small hinge mechanism? How could the hinge mechanism be strong enough to survive daily wear and tear?

Friction hinges usually have a stationary component and a moving component. Large stretches of area on the two components are compressed against each other with high force to create friction when the hinge moves. The holding torque from a friction hinge is generally correlated with the size of the hinge, since larger surfaces can support higher compression forces.

In the Nest Cam IQ hinge, we only had about a 10×10 mm envelope for our friction mechanism (including space for wires), so we had to think outside the box to get enough holding torque in such a small space. In the end, we created what we call a double-friction mechanism, which allowed us to have an unusually high torque density. First, we use the cosmetic “ball” surface as one friction interface by pushing against it with a plastic friction block and a high force spring. However, inherent in the mechanism design, we have a bonus friction source on the side of the mechanism by keeping the moving metal surfaces compressed together with a screw. This allows us to essentially double the holding torque without increasing the hinge size.

Material strength

When it comes to strength of the hinge assembly, the major factors are part geometry, part material choice, and loading path between parts. With such a small hinge and thin individual parts, we knew we could not achieve our design goals through just part geometry, so we focused heavily on materials selection and creating a robust assembly design.

The internal hinge mechanism components are precision machined out of stainless steel and phosphor bronze. These are very strong materials which can withstand a lot of stress before deforming or cracking. The cosmetic shell around the hinge, which we call the Stem, looks like the plastic head and base enclosures, but is actually an extremely stiff steel tube which provides structural reinforcement to the entire hinge mechanism. It is a great example of how we can achieve the beautiful form conceived by our Industrial Designers without compromising on functional engineering requirements.

Speaking of the stem, it is actually one of the most interesting parts in the entire device from a manufacturing perspective. This is a painted steel part that is formed by a process called deep drawing. It is incredible to think this long, slender tube with complex 3D features started out as a flat, circular sheet. Essentially, the metal sheet is stretched little by little over about a dozen stages until it reaches its final shape. Forming metal parts is a common manufacturing process, but seeing a part with this extreme of an aspect ratio is rare for a consumer electronics device, and a great testament to the work of our Manufacturing Operations team.

Thanks for reading about some of the design and development considerations around the hinge, and stay tuned to this blog for other cool Nest engineering and design posts!

Using Indoor Air Quality Tactics to Sleep Better at Night, Perform Well the Next Day


By Mary Kate McGowan, Associate Editor, News, ASHRAE Journal

A busy mind might not be the only thing to blame if falling and staying asleep is a nightly battle. The temperature and airborne pollutants, as determined by the heating, cooling and ventilation in a bedroom, might be the culprits.

People tend to fall asleep more quickly in bedrooms with comfortable temperatures and good air quality. These conditions also improve sleep quality, according to Pawel Wargocki, Ph.D., Associate Member ASHRAE.

For a good night’s sleep, the bedroom temperature should be set to a comfortable level before going to bed. Published research shows that the temperature is usually lower at bedtime than in the morning. The bedroom temperature’s slight increase during the night helps make the bedroom comfortable the next morning, said Wargocki, an associate professor at the Technical University of Denmark.

“If you really want to fall asleep quickly, avoid overheating,” he said. “When you wake up in a very stuffy environment, it’s not very pleasant.”

People also tend to sleep and feel better the next day when they sleep in a well-ventilated environment, he said.

If a bedroom’s window and door are closed for privacy and energy conservation purposes, the room’s ventilation rate is “so low that carbon dioxide (CO2), an indicator of poor indoor air quality (IAQ), routinely exceeds 2,500 to 3,000 ppm, which is three times the recommended levels,” according to published measurements.


Wargocki and his colleagues at the Technical University of Denmark examined the ventilation rate in a bedroom to see how it affected the sleep and next-day performance of a group of college students. The research showed that both sleep quality and next-day performance could be improved by the increasing the clean outdoor air supply rate in bedrooms.

“We know from other research that sleep quality generally affects how we perform the next day,” Wargocki said.

He presented the study during a seminar sponsored by TC 2.1, Physiology and Human Environment, and ASHRAE Standing Standard Project Committee 55, Thermal Environmental Conditions for Human Occupancy, at the 2016 ASHRAE Annual Conference in St. Louis.

Wargocki said only a handful of groups are researching indoor environmental conditions and ventilation in bedrooms, and the research is rarely performed in the subject’s own bedroom.

Many reasons exist for the lack of research in this complex field, including factors that affect sleep quality such as type of bedcovers, sleepwear, external noise disturbance and outdoor climate, according to Wargocki. Other reasons include people not allowing access to the most private part of their home and the lack of availability of simple, unobtrusive instrumentation for measuring sleep quality.

“Our study is one of the first studies of its kind available in literature because most of the research that has been done so far has been in sleep laboratories and in connection with other variables that could affect how well we sleep,” he said.


Wargocki and his fellow researchers performed two experiments in identical student dormitory rooms at the Technical University of Denmark. Sixteen students participated in each two-week period[1].

The researchers examined different interventions to improve bedroom air quality by increased ventilation and monitored the bedrooms’ carbon dioxide (CO2) levels as a marker of poor IAQ, according to Wargocki.

“We manipulated the ventilation rate in their bedrooms, and in the second experiment they were unaware of the changes we made,” he said. A window was opened in the first experiment, which was regarded as a pilot experiment, he said.

In the main experiment, the rooms had two conditions, increased ventilation and low ventilation (as if the windows stayed closed all night), each condition lasting for one week. Each subject experienced both conditions, in balanced order (i.e., experiencing 50% poor air quality first).

During the ventilated condition, an inaudible outdoor air supply fan was turned on automatically whenever the CO2 concentration increased to above 900 ppm. The fan was off all night during the “low ventilation” condition.

The students could open the windows during the day, but they had to remain closed during the night.

The CO2 concentration in each room ranged from 1,620 ppm to 3,300 ppm with fan off and from 795 ppm to 935 ppm with fan on, according to the research. The average CO2 concentration in the low ventilation condition was 2,395 ppm, with an average of 835 ppm, in the increased ventilation condition.


The students wore wrist-watch-type actigraphs that recorded arm movement to measure how long it took them to fall asleep, how often they woke up during the night, and how long they spent asleep; this information can be used to assess how well they slept.

The following morning, within 10 minutes of waking up, the students completed a self-assessment, online questionnaire asking how well they slept, how long they slept and other relevant questions. The students also performed two online tests that measured their concentration and attention, Wargocki said.

“What we observed was that when the fan was on and air quality improved, as indicated by lower CO2 concentration, it was easier for students to fall asleep, and they spent more time in bed when asleep,” he said, adding that those students also tended to perform better on the cognitive tests.

The students reported the air was fresher when they got up in the condition with fan on and that they felt better and more rested. However, they felt that their mouth and skin were drier, according to Wargocki.

Although the results were obtained with students, it is likely that the results can be generalized to the general population as well as other climatic regions, the research noted.

“Given these findings, it is reasonable to hypothesize that next-day performance would be better after sleeping in the conditions that provide better bedroom air quality. It was possible to show that this was the case, and to my knowledge for the first time ever,” Wargocki noted.

Because people spend almost one-third of their lifetime in a bedroom, Wargocki considers that there should be more research on how the bedroom thermal environment and IAQ affect sleep quality. He also said ASHRAE should play an active role in this endeavor.

Wireless Thermostat Kits with Receivers: Many Options from Which to Choose

When you absolutely need to connect a thermostat to an old fixed location, but the current wiring situation complicates the repair (or makes it too expensive), worry know more. We have a fix for that! In fact, we have several options.

Wireless Thermostat and Receiver Kits are available to help manage heating and cooling systems from anywhere in the house regardless of the current wiring issues. These control modules offer everything needed to relocate or upgrade with a thermostat without running new wires. And, it’s as simple as removing the old thermostat and replacing it with a wireless receiver!

The receiver is easy to install and is wired just like a standard 24VAC thermostat. The simplest solution is to just connect the unit to the old thermostat location. It can be wired in the furnace closet, attic or basement because the thermostat will communicate wirelessly. The temperature sensor is located on the thermostat, so place the thermostat anywhere the customer wants to control the temperature.

The thermostat can be placed in any location throughout your home — mounted to your wall or set on a shelf using an easel stand – anywhere from 100 up to 500 feet from the receiver depending on the model you choose. Transmitted radio signals from the thermostat to the receiver will be sent.

Most Wireless Thermostat Kits come with these options and features but still, be sure you choose the right model for your application:

  • Battery-powered
  • Manual or auto changeover
  • Programmable or non-programmable
  • Adjustable heating and cooling setpoints
  • Short cycle protection
  • Eliminates costly installation of wiring a thermostat
  • Up to 3H/2C
  • Gas or electric or heat pump
