We received your report, and you have some interesting results. We had some trouble relating some of the parts to the ADAMS model from the documentation, but the general mechanism is clear, and analysis appear good, although the LCA may need another look. Detailed comments follow:
- Nice executive summary
- Please include a picture of the product
- User lack of maintenance is a very big and very common problem. Encouraging customers to maintain wipers is quite important for safety, but putting an encouragement in the user’s manual is not generally sufficient to get results. This is one potential area for improvement because it is a significant cause of failure.
In our research we found some statistics to back up the clam that lack of maintenance is common and problematic which you can look at in the Windshield wiper ideas page. We also found that in interviews people say that it was difficult or annoying to maintain wipers. We addressed this issue mainly in the Exchangeable Blades/Rubber section of our redesign.
- Nice description of wiper use. Some additional detail on common issues, such as leaves getting caught under wipers, running out of wiper fluid, ice, and inability to remove some substances would make the discussion more complete.
If you go to the Windshield wiper ideas page you can see some the research done on common things that cause windshield wipers to break or degraded, common things wipers are used to clean (from rain to bugs), and under interviews you can see the issues people have with wipers.
- The component list is interesting, but it is difficult in some pictures to tell which component is being shown. The animation is quite helpful, but a picture of the partially assembled mechanism may also help to understand where parts are located on the assembly. This would also help in describing functionality.
- Materials are also not included. You may reconsider manufacturing of some components with constant thickness but bent shape - these may more likely be stamped and bent rather than cast.
Materials are now included for all parts.
- Functionality could be more specific in some places - for example, what is the “rubber cap” for? What is the (#7 + #8) notation?
- Nice summary of DFMA issues
- When you say “decomposition”, do you mean “disassembly”?
Yes, this wording has been changed.
- For EIOLCA, “motor vehicle parts manufacturing” would be a more representative sector than “automobile manufacturing,” which is for full vehicles. You mention that use of the product does not release greenhouse gasses, but this is not correct - there would be at least two sources: 1) the additional fuel burned to provide electricity to run the wipers when they are in use and 2) the additional fuel burned to carry around the extra weight of the wiper assembly unit. Do you have any intuition about whether use or manufacturing would likely have greater impact?
"Motor vehicle parts manufacturing" is the sector windshield wiper assemblies fall into. EOA data has been updated to reflect results of this sector. The correction has been made about greenhouse gasses emitted during product use.
- How does the intermittent mode of the wipers work?
- The ADAMS model is helpful in understanding the mechanism. The velocity analysis is interesting, but what does it tell us? Is this ratio good? bad? Should it be changed?
