Talk:Vacuum cleaner

From DDL Wiki

We received your report, and you have some interesting results, but we would like to see more detail specific to your design and more clear findings and conclusions. Comments follow:

• Executive summary is quite vague and generic. What are your findings and conclusions?
• Customer needs - should consider things such as ability to carry up and down stairs, noise, ability to clean alternative surfaces, etc.

- We agree with the comments regarding addition customer needs. The report has been updated to reflect these suggestions. We have considered things when moving forward with our work.

• The description of product function somewhat cursory. Please explain in more detail the mechanical function for your specific product. A figure would help.

- Additional research was performed and details were made clearer in the report. An addition of a diagram was also added to this section.

• Parts list is good, but it is unlikely that your screws are cast. Do you see evidence of casting?

- We have discoverd the correct manufacturing of screws and have modified the report to show this.

• It appears that you did not take the disassembly entirely down to individual components. For example, part #A-008 appears to be an assembly, rather than a single injection molded part. Please reexamine and clarify.

- Total disassembly took place, however some parts were only in pictures that included others. Arrows were added to images to clearify the part being referenced.

• Your FMEA is just a data table. What are your conclusions. We typically do not expect to see raw data without explanation or conclusion in a professional report.

- Conlcusions were left from the initial report. The suggestion/comment has been considered and we have updated the report to reflect our conclusions from the analysis.

• Your LCA is interesting, but the link to results does not function. You seem to conclude that impact from the use phase is greater than from manufacturing. Is this on the basis of GHGs? Should we focus on redesigning the product for reduced energy use?

- EIO-LCA has been updated to provide some of the referenced images as well as to show more findings of the study. The LCA has been refined to strengthen our suggestion of focusing on design for reduced energy use.

• It is difficult to follow the component air flow in your air flow analysis. Relating to an assembly figure would help. You seem to throw a few generic equations around, but what are the numbers for this design, and what do they tell you?

- Further analysis and clarification was made to the calculations as well as a conclusion to our findings.
