ID / MD / EE Integrated Design
Three Design Disciplines, Integrated in Parallel
Industrial design, mechanical design and electronic engineering collaborate within one development framework to reduce interface conflicts and late design changes.
ID | INDUSTRIAL DESIGN
Industrial Design
Product appearance and user interaction built around intended use, brand direction and production feasibility.
- Product positioning and design language
- Concept and form development
- Human factors and user interaction
- Material, color and surface treatment
- Appearance model and design approval
MD | MECHANICAL DESIGN
Mechanical Design
Structures that can be assembled, verified and manufactured while controlling tolerance, material and process constraints.
- Architecture and component layout
- Mechanism, sealing and mistake-proofing
- Material, process and tolerance analysis
- DFM/DFA and assembly review
- 3D/2D, BOM and engineering output
EE | ELECTRONIC ENGINEERING
Electronic Engineering
Electronic architecture developed according to function, size, power and reliability requirements, coordinated with industrial and mechanical design.
- System architecture and function definition
- Circuit, PCB and component selection
- Power, sensing and control design
- Electronic-mechanical interface integration
- Prototype testing and verification
Cross-disciplinary Integration
ID, MD and EE in parallel
Rather than a sequential handoff, the disciplines remain aligned through concept, prototype and verification so appearance, structure, electronics and manufacturing conditions fit together.
ID User Experience & Appearance
MD Structure & Manufacturing
EE Function & Electronic Systems
Design for Manufacturability
DFM Analysis for Product Development
Design for Manufacturability reviews product function, structure, materials, processes, assembly and inspection before prototypes, tooling and production investment. The objective is to identify risks that could affect cost, quality, schedule or production stability while engineering decisions are still flexible.
What should DFM analysis resolve?
1
Avoid discovering design changes at production
Confirm machining, molding, demolding, assembly and measurement constraints before engineering drawings are frozen.
2
Convert critical requirements into executable controls
Translate functional and cosmetic requirements into materials, processes, tolerances, CTQs and inspection methods.
3
Reduce cross-part and cross-supplier risk
Review tolerance and assembly relationships across metal parts, plastic parts, surface treatments and mating interfaces.
REVIEW INPUTS
Recommended Review Information
Product & Engineering Data
2D/3D, BOM, functional requirements, mating parts and current revision
Material & Cosmetic Requirements
Specified materials, color, texture, surface finish and appearance acceptance criteria
Production & Quality Conditions
Estimated quantity, critical dimensions, inspection focus, assembly method and target schedule
DFM ANALYSIS OUTPUTS
Typical DFM Project Outputs
- Design-risk and open-item list
- Drawing, geometry, tolerance and material recommendations
- Recommended processes, tooling, fixtures and assembly direction
- CTQs, measurement methods and sample-verification priorities
- Decision basis before prototypes, tooling or pilot production
DFM Review Matrix
DFM Review Matrix
01 | REQUIREMENT
Requirements & Interfaces
Confirm intended use, functions, operating scenarios, component boundaries, mating interfaces and fixed constraints.
02 | MATERIAL
Materials & Processes
Evaluate CNC, molding or combined processes against strength, appearance, resistance, cost and supply conditions.
03 | GEOMETRY
Geometry & Tooling
Review wall thickness, ribs, draft, undercuts, tool access, workholding and mold construction.
04 | TOLERANCE
Tolerances & CTQs
Establish datums, tolerance stacks and critical-to-quality characteristics without unnecessary tolerance or fit risk.
05 | ASSEMBLY
Assembly & Mistake-proofing
Review assembly sequence, location, fastening, fixtures, serviceability and manual-operation risks.
06 | INSPECTION
Inspection & Verification
Confirm measurement datums, gauge feasibility, cosmetic standards, first article and functional verification methods.
Design Transfer Package
Design Development Transfer Documentation
The value of design is realized when production can receive it completely. At project transfer, a structured documentation package supports production introduction and the customer's design-history and technical-file needs.
D-01
Engineering Drawings
Released 2D/3D files, tolerances, CTQ identification and revision records.
D-02
BOM & Specifications
Material list, specifications, surface finish and purchased-part definition.
D-03
Process Documents
SOP, Control Plan, tooling list and approved process parameters.
D-04
Verification Records
Test reports, FAI, pilot reports and design-freeze records.
