Completing the questionnaire for refrigeration system design
Approving the project development plan (including plans for electrical, quality, systems, and mechanical)
Audit & Research
Measurement & Evaluation
The detailed design phase starts with defining options for the product architecture, with the goal of having the greatest chance of successfully meeting product requirements while best mitigating risk. Some engineering activities in this phase include presenting options for system components, outlining the system’s overall size, sequence, and state diagrams, creating a rough solid model, and breadboarding of high-risk subsystems. Results are presented with a description of the pros, cons, and key tradeoffs for each scenario.

3A. Prototype 1 Design, Build and Test
Phases 3A and 3B are typically the largest efforts in the product development journey, where the specific implementation for all disciplines occurs (mechanical and electrical design, systems, software, manufacturing, and quality). At this stage, we start the engagement with different suppliers to obtain product samples, get the main suppliers involved to provide additional manufacturing/design input on the system. Because this product will have stringent testing or certification requirements, pre-screens are performed in this phase prior to formal regulatory agency testing such as ATEX, UL, or ETL.
Build a prototype sample
Layout 3D CAD files
Design failure mode, and effect analysis (FEMA)
Test plans and reports
Unit build plan – from prototype to pre-production
Initial Bill of Materials (BOM)
cost analysis, and manufacturing process identification.
Update schematics and layout
3D CAD files and 2D drawings
Bill of Materials (BOM) update
Cost, build, and quality plan development
This phase occurs once the detailed design is complete, and prototypes are built with manufacturing-representative quality and detail. Per customers requirements, more extensive, formal testing is performed, such as life, reliability, safety, environmental, drop, and vibration….. The design and manufacturing team at Craft work closely to enable a smooth transfer.
Formal verification test reports are completed by the appropriate agencies
Final improvements are made
