Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple electrical functional elements and control panels are integrated into the laminated glass unit, then functionality and control capabilities are enhanced, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent combines multiple electrical functional elements (sun visor, LED, OLED, display) and their control panels into a single laminated glass unit. The control panels are integrated directly into the lamination structure, merging control functionality with the glass assembly itself rather than having separate control units. This reduces overall system complexity while maintaining versatile functionality.
Solution Approach 2:
The laminated glass unit serves multiple functions simultaneously: it acts as a structural glass component, an integrated sun visor, a light source (LED/OLED), a display medium, and a control interface. The single glass unit replaces what would traditionally require multiple separate components, achieving multi-functionality within a unified structure.
2Volume of moving object
If multiple functional elements are integrated into the same laminated glass unit, then space requirements are reduced, but manufacturing precision and optical quality become more difficult to maintain
Solution Approach 1:
The patent divides the laminated glass unit into distinct functional zones or layers, with each electrical element and control panel positioned in specific regions. This segmentation allows each component to be manufactured and positioned with appropriate precision requirements, while the overall integration achieves space efficiency. The lamination process itself creates natural segmentation between different functional layers.
3Ease of operation
If complex control functions are integrated into the glass unit, then ease of operation is improved, but ease of manufacture and production cost-effectiveness deteriorate
Solution Approach 1:
The control panels and electrical elements are pre-positioned and pre-assembled within the lamination structure during the manufacturing process. This preliminary action allows complex control functions to be integrated in a systematic manner during production, rather than requiring complex assembly operations later. The lamination process itself performs the integration action in a single manufacturing step.
