Talk:Ice cream maker
From DDL Wiki
We received your report, and we are impressed with your findings. Detailed comments follow:
- Please include a picture of the product at the top of the document
- Very clear executive summary with findings highlighted
- Good discussion of basic customer needs, but more detailed discussion of specific needs such as noise, safety, speed, etc. would be helpful
- A technical description of how the ice cream maker functions appears to be missing
- The components list is clear. Is the motor spindle holder a single component or an assembly? How about the mixing bowl?
- How are the aluminum and plastic components of the mixing bowl sealed to avoid leakage of the thermal fluid?
- Good observations for DFMA. The ideas to look into merging gear assemblies to reduce part count is worthwhile for us to investigate.
- FMEA - you identified some important failure modes. The data from customer complaints on amazon is also useful for helping identify places for focus.
- Your LCA analysis is interesting. You conclude that the manufacturing stage is where most of the energy is consumed, but it is not completely clear from your numbers. $1 million worth of manufacturing is 598 MTCO2E, and under your assumptions the $1 million of ice cream makers is associated with 4kWh of electricity. What is the MTCO2E associated with this electricity? Also, is the energy used by a refrigerator to cool the mixing bowl negligible?
- Your quantitative analysis uses P = 50W. Where did this number come from - is this the power listed on the motor ?
