Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional plastic materials are used for the operating device, then manufacturing cost is reduced, but the device lacks an upscale appearance and premium feel
Solution Approach 1:
The patent employs composite material structures combining metal layers (for premium appearance and tactile feel) with plastic substrates (for manufacturing ease and cost-effectiveness), creating a multifunctional operating device that achieves both upscale appearance and reasonable manufacturing cost
2Shape
If metal materials are used for the operating device, then an upscale appearance and premium feel are achieved, but manufacturing cost increases and processing becomes more difficult
Solution Approach 1:
The patent uses composite material structures where metal layers provide premium appearance and tactile properties while plastic substrates maintain manufacturing ease and cost-effectiveness, avoiding the full cost and processing complexity of solid metal construction
