Project Overview

Team 13A intends to design, create, and implement an automatic, solar sensing blind controller. The basic idea is that the controller will include some solar sensors that track the sun’s position and adjust the blinds position according to some user defined parameters. The intent of the project is save the user money by adjusting blinds for the most energy efficient setting. The team also intends to have user programmable settings for convenient lighting. For example, the user can set the blinds to open at 7:30 AM to allow for natural lighting to wake up the user.

Automatic solar sensing blinds are part of the smart home industry. The market is just now beginning to grow, with the only main competitor being Flip Flic: a stand alone unit aimed at tackling the automated blinds in a similar fashion. Team 13A has focused on  a minimalistic design that they hope will bring them success in the market. Currently smart home technology is bought in large purchases for home remodel or mass home integration. Many smart home products are integrated with smart assistants like Alexa or Siri. Team 13A hopes that their minimalistic design can undercut competitors while still giving an elegant design, and keep it simple enough that integration with other smart home technology can follow.

Proof of Concept

Solar Sun Systems is trying to prove that the use of an automated blind system has the potential of lowering the heating and cooling costs of a home or office by allowing solar energy to enter a building via particular blind angles. These solar sensing blinds will be a part of the growing smart home market which aims at having efficient control of consumer level spaces, using either automation, phone applications, or voice control.

The purpose of the blinds will be to optimize the amount of sunlight or heat entering the living space. For example, during winter months, the blinds will allow the maximum amount of light into the home for proper heating. The system will be powered by a rechargeable battery and a solar cell. The system will run and a motor will drive the blinds to the appropriate orientation based on the data gathered from four light sensors. The user will also have the ability to position the blinds in whichever orientation they would like by using buttons which can move the motor.  The system will also calibrate nightly to ensure the system can know where the blinds should be in the “closed position.”

Final design

The product is a modular, solar sensing and tracking device that will adjust blinds according to the sun’s position and the temperature needs within a home or office. The device should be self-sustaining by running continuously without user input, and by being run via solar power. The product will feature two separate units, connected via cable: (a) housing containing the circuitry and mechanical components that is attached to the pre-existing blind system and (b) solar cell with a semi-circular bulb containing the photocells.

The unit will be capable of tracking the sun throughout the day and adjusting the blinds to maximize the incoming light into the room while in the heating mode. While in cooling mode, the blinds will primarily remain closed unless the user manually opens the blinds. These settings have been determined to be the most optimum for heating/cooling of the home.

The original intent of developing solar sensing blinds was to decrease energy cost by minimizing energy loss through the least insulated part of the common home, the window. For example, if one were to leave their blinds open all day in the summer or closed all day in the winter, a central air conditioning and heating unit would have to expend unnecessary energy in order to keep the space at a desirable temperature, rather than letting nature passively aid the situation. Solar sensing blinds allow for the blinds to automatically optimize themselves throughout the course of a day, so even if the owner is not home their blinds are adjusting in a way that reduces the work the rest of the heating and cooling system must undergo to maintain a temperature. Additionally, energy could be conserved by utilizing ambient light from the sun to illuminate a space, rather than relying on artificial lighting that requires the expense of energy.

As Blinding Sun Systems continued to develop the product, the team realized many other potential benefits of the product as well, including home security by giving the appearance of subtle, yet constant activity and simply the convenience that home automation provides in opposed to manually adjusting each set of blinds. Consumers could derive benefit from solar sensing blinds simply because they would no longer have to even concern themselves with the movements of their blinds throughout the day. Blinding Sun System’s take on solar sensing blinds also offers a low-cost entry into home automation, a popular growing market that promotes passive energy conservation and cost savings through added convenience.

Fabrication

Fabrication of the solar sensing blinds attachment is being completed almost completely via additive manufacturing techniques, along with utilization of some off the shelf parts. Using a Fusion3 3D printer, Blinding Sun Systems can capture the accuracy required for all of their parts using PLA or Carbon Fiber 1.75mm filaments. Several components including the hook attachment, housing, and solar panel fixture are being printed via the 3D printer, allowing a very low manufacturing cost. If the project were to be taken to mass manufacturing scale, it is likely that 3D printing would still be a viable option for mass production of parts, quickly and inexpensively. Off-the-shelf components being used in the fabrication largely include the electronics – a solar panel, battery, breadboard, motor, and arduino. The 3D printed parts are being designed to build around the dimensions of the off-the-shelf parts.

Several different connections are being utilized to easily assemble the components. For example, there should only be four screws required to assemble all components. All other fixturing is being done by design. For example, the hook attaches directly to the motor via a compression fit, and the housing will clip together using snap hooks.
