91-315 Manufacturing Driven Product Design
Tutorial 7 – Nov. 9, 2015, Group Report Due: Nov. 16, 2015
Term Project Phase 2: Concept Generation and Evaluation & BOM
Based on the function definition task done in the previous lab (Part B of Lab#6), conduct the following tasks for both
your Group Winner and Group Backup ideas.
a) Using one of the provided QFD template, you are asked to translate all functional statements prepared last week
into related technical attributes. (TRIZ’s 39 engineering parameters are a good starting point for technical
attributes).
b) For each technical attribute, identify the associated constraint and (or) target level. (at the bottom of the columns!)
c) For each or a group of technical attributes, identify the related technology that can be used to
produce/assembly/manufacture this part/module. Using a separate Excel sheet, identify all these technologies
whether it is 1) available, or 2) possibly available through minor investigation/research, or 3) possibly available
through major investigation/research, or 4) not available with the current technology. For those technical
attributes that are identified not available in-house, estimate (to your best knowledge) how much time and budget
is required in order to procure/investigate/discover this new technology.
d) Based on the function hierarchy and the technical attributes, construct the product tree (or BOM). Calculate the
capital cost required for those parts built-in-house and estimate the unit cost for those parts that will be purchased.
Provide a rough estimate for the unit cost.
Note: The technical attribute configuration is treated as an intermediate step toward your final product structure
configuration. If you have already clear view of how your product structure is about, you can simply present the
product structure and skip the technical attribute configuration step. However, you still need to identify the targets and
constraints for some of the technology and components in your product (remember these are called specifications and
benchmarking targets!). As well, you also need to identify the technology readiness for each of the component/part in
your product structure.
Note: Your group submission include three separate files: 1) QFD template; 2) technology readiness evaluation
(from part c); and 3) Product Structure (or Bill-of-Materials BOM).
