Weekly Team Update

As the semester is wrapping up, the Full-Scale Mounting team is finishing up their work while directing their energy to the Final Paper for ME 195a.

The team will be finishing loose ends on several topics related to
1. Finalizing the velcro being used.
2. Cleaning up the Ansys simulation of the load
3. Condensing the final design down to a half model and flipping it opposite to have a East-West facing frame construction.
4. Cost Analysis and Bill Of Materials

With these tasks in mind, the team is looking to be wrapped up for the semester after the paper. Time will be devoted over the break to brainstorm more ideas that have not been address yet.

12/3-12/7

Weekly Team Update

Our main goal for this week was to focus mainly on our Presentation 3. We have fallen short on the last two presentations and worked diligently to provide a presentation that better represented our progress and work. We are still waiting on some FEA analysis of the canopy structure that will be done before the end of next week. We received great feedback from professor furman and will continue to get in contact with distributors for our parts as well as further improving our design for the solar canopy. Linked below is our presentation 3.

On the week of 11/14, The Full-Scale Solar Team is continuing work to provide an excellent solution to mounting and servicing solar panels from underneath the solar mount frame. Along with this, the team is also solving how to put the frame onto the guideway when construction of the frame is complete, as well as keeping the manufacturing of the frame as simple as possible, preferably avoiding custom parts to ensure a faster and cheaper production of these frames in the future. In summary the work for this week heading into Thanksgiving break will be as follows.

1. Each member will tackle a different solution for servicing the solar panels
    - Jordan: Will test industrial velcro as a viable solution
    - Patrick: Will test griping mechanism from the underside of the frame
    - Francisco: Will test griping mechanism from the outside of the frame, just as a fall-back case to ensure that a design will be made



2. Members will start working on a structural analysis of the frame as well …

On the week of 11/7, the Full-Scale Solar Team was able to develop the end goal for the solar canopy fixture on SolidWorks, shown below in Figure 1. Figure 1. Solar canopy mount.
For the method of mounting the solar panels to the fixture the idea of using a clamp to secure the panels was chosen, as opposed to using an adhesive or industrial grade Velcro. This was chosen with the idea of having the least amount of error when assembling the solar canopy during installation. The decision of the specific clamp is still in discussion, but will look something like the one in Figure 2.
Figure 2. Concept of clamp to secure panel to fixture
To stay on track, a small-scale prototype will be developed to provide a hands-on feel. A 3D prototype will be printed in addition to an Ansys of the CAD model and cost for parts. Lastly, the Full-Scale Solar Team will analyze the comments from our adviser and create a list of what we are missing and/or need.

On the week of 10/31, The Full-Scale Solar Team is working on building a solid assembly for the canopy system. This assembly will provide a much more detailed design on how the solar panels will be attached to the canopy. 

Here is the preliminary design concept for the canopy fixture that will support up to 9 solar panels on it. We've discussed ways to attach the solar panels to the canopy, after having another meeting with our instructors we have come up with more ways that we potentially want to use to support the solar panels. Possible methods include industrial grade adhesives, industrial velcro, even a sheet metal clamp with piranha like teeth to clamp onto the underside of the solar panels. We will be coming to a conclusion to what system to use by the end of this week.


Here is the progress for the canopy with actual joints found on mcmaster, this assembly will be done before our class on the 7th. Other considerations to take into our design is the wind loading conditions exp…

On the week of 10/24, The Full-Scale Solar is working on several aspects of our design specifications, along with intra-team communications with the Guideway and Wayside Power Teams. For the design specifications work, the team has broken the problems into 4 tasks,

1. Talking to the guideway team to figure out specific requirements based on their guidelines and see if we need to scale down our project or anything along the lines of support the mount x 6.
2. Talk about how our solar panel mount will support the panels and how to fit the panels from underneath instead of from above.
3. How to connect each piece of the mount to each other, is it going to be a solder, is it going to be bolts, screws, etc..
4. Figure out how to communicate with our sub teams, and with the team, more effectively than it has been.

once a plan has been settled with each of these aspects, the plan will be presented to Dr. Furman and Mr. Swenson for additional recommendations and questions.

Weekly Team Update

On the week of 10/17/18, the Solar Canopy continued to discuss the improvements of the current solar panel mount. Currently, all members are working on concept model ideas, as well as methods on how to fix the solar panel mount to the guideway. Seeing as that the guideway is not a solid block, the mount would have to be fixed on two opposite ends and would make the design to be aware of this, because it cannot have too much stress in a spot where it is not properly loaded. Specifications from the guideway team are coming soon, before next week's meeting. Energy requirements from the wayside team have also been changed from 340 Kilojoules to 450 Kilojoules, pushing us to be more conscience about having more solar panels on our design. If we have too many panels on the design, it will not fit or it will be too angular for design, but if we have too little, we will not meet the energy requirement in a reasonable time frame, seeing as that the average panel delivers only 60 Watts.
