Key Tasks:
•
Complete lifecycle design of plastic enclosures and mechanical assemblies for consumer electronics.

Development of DFM- and DFH-oriented solutions considering mass production processes (plastic injection molding, assembly, sealing, serviceability).
•
Collaboration with hardware and embedded engineers, industrial designers, technologists, quality control, and manufacturing departments.
•
Design of ergonomic, intuitive solutions adaptable to different operating environments.
•
Preparation of production transfer documentation (2D drawings, specifications, technical requirements, 3D models for molds).
•
Support of mold development and approval of modifications after initial mold trials (T0–T2), including defect analysis.
•
Participation in testing and feedback from prototypes and production, incorporating design improvements.
•
Verification of engineering compliance of the finished product with expected technical parameters (stiffness, assembly, weight, IP protection).
•
Oversight of the product lifecycle from concept to mass production, including cost analysis and assessment of the impact of design decisions on production costs.
•
Communication with Chinese factories: technical specifications, drawing reviews, change control, feedback on prototypes and production samples.
•
Assessment of manufacturing risks in China: equipment limitations, mold quality, shrinkage, production tolerances, and the influence of packaging and logistics on design.
•
Inspection of samples from China: defect analysis (shrinkage, warping, poor casting), initial product assembly, and reporting with recommendations.
•
Consideration of potential scaling difficulties in China: timeline tracking, mold duplication, and price optimization.
•
Continuous communication via email, video calls, document comments (in English), and participation in editing specifications based on feedback from the Chinese side.
