Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the display apparatus is thinned to improve portability and design, then the device becomes thinner and lighter, but electrical characteristics and durability deteriorate due to reduced space for proper circuit layout and connection
Solution Approach 1:
The circuit cover is divided into multiple functional regions: a main body portion covering the circuit board, a wing portion extending to contact the circuit board edge, and a connection portion bridging between them. This segmentation allows each region to perform its specific function optimally while maintaining thin overall profile.
Solution Approach 2:
The circuit cover extends in multiple directions (wing portion extending laterally, connection portion extending vertically/toward protective panel) to create three-dimensional electrical connection paths. This multi-directional approach enables stable electrical connections without increasing the horizontal footprint, thus maintaining device thinness.
2Reliability
If precise characteristic control is implemented to improve electrical performance, then electrical characteristics improve, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The circuit cover serves multiple functions simultaneously: it provides mechanical protection for the circuit board, establishes electrical connections through the wing and connection portions, and ensures proper grounding through the conductive layer. This multi-functionality reduces the need for separate components, simplifying the overall device structure.
Solution Approach 2:
The connection portion acts as an intermediary element that bridges the main body portion and the protective panel, establishing electrical connection paths without requiring direct contact between the circuit board and protective panel. This intermediary structure simplifies the connection architecture while ensuring reliable electrical characteristics.
3Ease of manufacture
If the circuit cover structure is simplified to reduce manufacturing complexity, then ease of manufacture improves, but electrical connection stability and grounding reliability deteriorate
Solution Approach 1:
The circuit cover features localized conductive layers in specific regions (wing portion and connection portion) rather than uniform conductivity throughout. This local quality approach ensures electrical connections are established only where needed, maintaining manufacturing simplicity while ensuring reliable electrical connections and grounding at critical locations.
