Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate reflective member layer, touch electrode layer, and pressure sensing layer are manufactured independently, then each function (mirror, touch sensing, pressure sensing) can be achieved, but manufacturing cost increases
Solution Approach 1:
The patent combines the reflective member layer, touch electrode layer, and pressure sensing layer into a single integrated structure. The reflective member layer is formed to simultaneously serve as the touch electrode layer and pressure sensing layer, eliminating the need for separate manufacturing processes for each function. This merging reduces manufacturing complexity and cost while maintaining all required functionalities.
Solution Approach 2:
The reflective member layer is designed to perform multiple functions simultaneously: it provides mirror functionality through its reflective properties, serves as the touch electrode for capacitive touch sensing, and acts as the pressure sensing layer for detecting finger pressure. This multi-functionality approach allows a single layer to replace what would traditionally require three separate layers, reducing overall manufacturing cost.
2Adaptability or versatility
If multiple additional layers and processes are added for touch and pressure sensing functions, then sensing capabilities are achieved, but device complexity increases
Solution Approach 1:
The patent merges the touch electrode layer and pressure sensing layer with the reflective member layer, creating a single integrated structure instead of multiple separate layers. This reduces the overall structural complexity of the display device while maintaining touch and pressure sensing capabilities. The reflective member layer itself is configured to provide both touch electrode functionality and pressure sensing functionality.
Solution Approach 2:
The reflective member layer is designed as a multi-functional component that simultaneously provides optical reflection for mirror display, electrical conduction for touch sensing, and mechanical sensing for pressure detection. This universality eliminates the need for additional dedicated layers for each sensing function, thereby reducing device structural complexity.
