Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the gap between the display panel and printed circuit board is reduced to improve antenna performance, then antenna performance losses are minimized, but device complexity increases due to the need for precise positioning and support structures
Solution Approach 1:
The support structure is integrated with the display panel assembly, combining mechanical support and electrical connection functions into a unified component. This merging reduces the number of separate parts while maintaining the required gap reduction for antenna performance.
Solution Approach 2:
The support structure acts as an intermediary element between the display panel and printed circuit board, providing both mechanical support and electrical coupling while enabling the close spacing required to minimize capacitive coupling losses.
2Adaptability or versatility
If multiple components are included in compact designs to enhance device functionality, then device versatility improves, but capacitive coupling between components increases causing performance losses
Solution Approach 1:
The support structure provides localized electrical coupling properties between specific components (display panel and PCB) while maintaining overall device versatility. This local optimization allows close spacing in critical areas without causing widespread capacitive coupling issues.
Solution Approach 2:
The electrical coupling characteristics are modified through the support structure's conductive elements, changing the capacitive coupling parameters between components to reduce energy losses while maintaining compact multi-component design.
3Length of stationary object
If the display panel and printed circuit board are positioned closer together to reduce device thickness, then device portability improves, but capacitive coupling increases causing antenna performance degradation
Solution Approach 1:
The support structure serves as an intermediary that enables close positioning of the display panel and PCB while managing the electrical interaction between them, allowing thin device design without severe capacitive coupling penalties.
Solution Approach 2:
The electrical parameters of the interface between display panel and PCB are optimized through the support structure's conductive elements, allowing reduced spacing for thinner devices while controlling capacitive coupling effects.
