Japanese product teams commissioning industrial design, mechanical design and prototypes should request separate items for design, part fabrication, assembly verification and later revisions. Product use, existing drawings, materials, processes, prototype quantities and acceptance conditions are needed to compare the work included in each quote.
Beijing Winge Technology Co., Ltd., operating as Winge, provides product engineering and prototype development services. The following is a suggested inquiry and review method; project documents define the scope, delivery rights and commercial terms.
Inputs needed before quoting
Describe product use, operation, installation, envelope constraints, existing boards and display modules. Provide editable designs, drawing revisions, interface positions and the items to retain or change.
Distinguish appearance models, assembly check samples and functional prototypes. List quantities, customer-supplied parts, checks and pass conditions for each. If drawings are missing, start with a document inventory and concept assessment.
Design, fabrication and revision checklist
This checklist defines quotation inputs and cost boundaries; it is not a public price list.
| Item | Inputs to confirm | Quotation and responsibility boundary |
|---|---|---|
| Design scope | Appearance direction, mechanical parts, source formats and review rounds | Itemize appearance concepts, detailed mechanical design and document preparation |
| Materials | Material grades, required properties and substitution approval | Confirm material procurement and validation after substitutions separately |
| Fabrication process | Sample process, surface finish, tolerances and inspection features | Quote sample fabrication and production tooling separately; neither is automatically included |
| Quantities | Part counts, complete sets, spares and repeat orders | Quote the agreed batch; reassess materials and processes for additional fabrication |
| Assembly and checks | Board dimensions, connectors, cables, fasteners and supplying party | Specify loose parts or assembled prototypes, with agreed checks and records |
| Revisions | Change ID, reason, before/after revisions and affected parts | Distinguish agreed defect correction, new requirements and fabrication charges |
Agree the work package and check deliverables
An initial package can cover document checks and layout and assembly risk reviews, delivering an input gap list, scope table and subsequent work packages. Price and schedule depend on the agreed work, procurement and validation conditions.
Agreed design deliverables can include 3D models, 2D engineering drawings, assembly instructions and change records. Check that files open in the agreed formats and that part, drawing and assembly revisions correspond.
Prototype acceptance records should identify the unit, material and fabrication state, customer parts, check method, dimensional or functional pass conditions, actual results and unresolved issues. Approval of an appearance model does not replace full product or production validation.
Linking Japanese review records to drawings
If Japanese panel text or review documents are required, confirm text revisions and display areas together with drawing revisions. Use one change ID to link Japanese descriptions, part numbers, drawings before and after the change, and approval records.
Agree working language, file formats, prototype shipping, currency, taxes and certification work separately. A country name does not establish applicable requirements or fixed charges.
Questions and answers
Can a product concept be quoted first?
Scope can be assessed first, but document preparation, concept design and physical fabrication should be separated. List undecided materials, dimensions, quantities and acceptance conditions as quotation assumptions.
Does prototype approval mean production can start immediately?
No. Prototype and production materials, processes, tooling, assembly and inspection conditions may differ and need a separate review and validation.
How is a second revision charged?
Record the reason, revision differences, affected parts and retest scope. Apply the agreed distinction between defect correction and new requirements, and confirm materials, external fabrication and assembly costs separately.
