Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the display apparatus is thinned to improve portability and design, then weight and thickness are reduced, but electrical characteristics and durability deteriorate
Solution Approach 1:
The patent employs thin-film structures for the circuit board and circuit cover portion, achieving weight reduction while maintaining electrical functionality through optimized thin-film conductor and insulator layers that preserve electrical characteristics despite reduced thickness
Solution Approach 2:
The patent uses composite material structures combining multiple layers (conductive layers, insulating layers, protective layers) in the circuit board and circuit cover portion to achieve both thinness and durability, where each layer contributes specific properties that collectively resolve the contradiction between weight reduction and reliability maintenance
2Weight of moving object
If the display apparatus is thinned to improve portability and design, then weight and thickness are reduced, but durability deteriorates
Solution Approach 1:
The circuit cover portion is designed as a thin-film structure with multiple layers including conductive and insulating layers that provide both weight reduction and structural durability, where the thin-film design maintains strength through optimized layer composition and bonding
Solution Approach 2:
The circuit cover portion is disposed to surround and protect the circuit board, creating a nested protective structure where the thinner circuit cover portion encloses and shields the circuit board components, enhancing durability without adding significant weight
3Reliability
If precise characteristic control is implemented to improve electrical characteristics, then electrical performance improves, but device complexity increases
Solution Approach 1:
The circuit cover portion features different regions (wing region, connection region) with specialized functions and structures, where each region has optimized local properties (conductive layer configuration, insulating layer placement) to achieve precise electrical characteristic control without requiring complex overall design
Solution Approach 2:
The circuit cover portion is divided into functionally distinct regions (wing region for electrical connection to circuit board, connection region for electrical connection to protective panel) that can be independently optimized and manufactured, reducing overall device complexity while maintaining precise electrical characteristics
