R&D process:
STEP 1: Based on market feedback, conduct demand research + understand user pain points
STEP 2: Start internal review, establish the project and clarify development requirements, as well as corresponding functions and specifications
STEP 3: R&D, design the basic dimensions of the product, and stack it
STEP 4: ID engineers focus on preliminary stacking 3D for product appearance design
STEP 5: After the appearance design is confirmed, the structural engineer will design the internal structure and pump core.
STEP 6: The pump core is the core. Before opening the plastic mold, the function test of the pump core must be OK, and the plastic 3D printing must be used for assembly inspection, life test, and cooling system inspection.
STEP 7: After confirming the life of the pump core and satisfying the performance, the plastic parts will be molded and the PCBA will be developed and designed.
STEP 8: After the plastic mold completes T0, start the first engineering sample build (engineer sample build), usually 20 units. After the trial production, problems that arise during the trial production will be collected, and test items will be arranged according to the test documents.
STEP 9: Improve ESB problems and problems that arise during testing. After the improvements are completed, you can enter the next stage.
STEP 10: ESB will be in the EB (engineer build) stage from now on, with a quantity of 50 units. Verify the problems that arise in the ESB and arrange testing to collect whether there are any problems. If there are no problems, relevant certifications will be arranged simultaneously.
STEP 11: After the EB problem improvement is completed, determine whether to enter the QB (Quality build) stage based on the actual situation. If there are too many problems and the conditions cannot be met, continue to arrange EB2.
STEP 12: The QB stage is a small batch trial production with a quantity of 100 units. The products are produced according to normal conditions and can be shipped if there are no problems.
STEP 13: If QB is completed without exception, it means that the product has been mass produced.
