Window Mounted Solar Light
This is a 3D printed Shade for the Window Mounted Solar Light. The idea is to transform the regular outdoor Solar Light into the indoor light source. The Solar Light consists of 3D manufactured shade, three discarded plastic suckers with broken hooks, and the discarded garden solar light with the broken pole.
This Case Study was developed to illustrate several Eco-Design principles apart from the main one - use of renewable decentralized energy source:
• Recycling, reusing and repurposing, which refers to the discarded plastic suckers with broken hooks, and LED, switch, and other parts of the solar light, which usually is equipped with the plastic pole lacking rigidity, so it breaks quite often;
• Minimising amount and number of material required to manufacture and assembly the product, which refers to the push-fit assembly, where shade is playing the role of the fixture at the same time;
• No permanent joint solution is representing Design for Disassembly principle, as well as highly adaptable solution allowing quickly disassemble the product to substitute the batteries or any other part if needed.
Various researchers argue, that energy consumption during the use phase of the products, which need power in order to function, is far greater comparing to the energy needed for their manufacturing. On the other hand, the products like wall mounted hooks with suckers, and garden solar lights are not durable, and the solution offering the second life option for their parts illustrates well the Sustainable design approach.
The 3D manufactured shade at the same time is playing the role of the fixture for the all the parts of the solar light. There are no screws needed to put together the Window Mounted Solar light, it is just a push-fit simple assembly. In order to achieve this kind of precision the discarded solar light and suckers were measured, so the 3D manufactured element openings are exactly the same size. In order to get the same results with the garden solar light MISMIR user has, the downloaded 3D printable file may need some alterations in terms of size. The Window Mounted Solar Light has a rechargeable accumulator, LED light, and the switch mechanism industrially manufactured and installed inside the solar light.
The time needed for 3D manufacturing of the shade/fixture should take approximately 4-6 hours depending on the density chosen.
The Window Mounted Solar Light needs to be assembled in the way the switch is positioned in front of the ornamental opening in the demi sphere of the 3d manufactured shade, so the switch is reachable for the finger. The fixtures for the suckers, the three cylinders, have grooves inside to secure the sucker legs in place. As an additional measure, to secure them in place it is recommended to sand a bit the sucker legs with a fine sanding paper so they have a rough surface. As the Window Mounted Solar Light weights so little, just 130g and is equipped with three suckers, when put on the window glass, it holds firmly. The suckers, on the other hand, are made of transparent plastic, so they do not interfere with the charging of the solar cell. The assembly may take 0,5 – 1 hour.
BILL OF MATERIALS
o 1 3D manufactured shade/fixture;
o 3 suckers;
o 1 outdoor solar light.
The Window Mounted Solar Light may prove to be physiologically comfortable solution. We all are used to the fact that during the daytime light comes indoors through the windows, but during the nigh time the artificial light sources are positioned everywhere in the room except the window. Probably, positioning the artificial light source where the natural daylight is usually coming from will be more comfortable for the people physiologically? This is a question is not to be answered by this Case Study as it requires deep comprehensive research.
