Re-evaluating & comparing two designs
After the initial DFX analysis of a certain MBOM, different conclusions will be made about the design and likely resulting in a proposed re-design of the product. It is thus a logical step to compare the “DFA score” for the original MBOM with the new re-designed one.
Re-evaluating new design
- Make a new version of the entire assembly
- Open the new version in the assembly view
- In the new version you can now make changes to the DFA analysis according to your conclusions, e.g. removing parts and making new versions of parts that has changed
If new versions of a part in a sub-assembly is made, first create a new version of the sub-assembly and then new versions of the parts that has changed.
COMPARING DFA SCORES
When comparing two designs it is noticeably that an improved design might have a lower DFA score than the original design. This is because eliminating a part will reduce the total score, making it difficult to compare designs using the DFA-score (Aggregated score) itself.
When comparing two designs, you can:
- Use the Agg Score (%)
- Use the theoretical DFA-time
- Each DFX aspect generates a time based on a theoretical optimal assembly. Thus, comparing two designs where the new design has a lower DFA score it will also have a lower DFA time since it conatins less parts
- Each DFX aspect generates a time based on a theoretical optimal assembly. Thus, comparing two designs where the new design has a lower DFA score it will also have a lower DFA time since it conatins less parts
- Compare the total number of parts.
- Less parts will be a simpler (better) design
- Less parts will be a simpler (better) design
