Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If metal-mesh structures with electrically conductive layers are used for touch control, then touch control performance and bending resistance are improved, but visibility and reflectivity worsen under intensive light due to visible patterns
Solution Approach 1:
The patent introduces a shadow eliminating layer as an intermediary component between the electrically conductive layer and the external environment. This layer specifically targets and eliminates the harmful shadow effects and light reflections caused by the metal-mesh structure, allowing the touch control function to be maintained while the visual appearance is improved. The shadow eliminating layer acts as a mediator that resolves the conflict between functional performance and aesthetic appearance.
Solution Approach 2:
The shadow eliminating layer modifies the optical properties of the metal-mesh structure by changing how light interacts with it. By introducing this layer, the visible patterns and reflections are reduced or eliminated, effectively changing the visual appearance from a visible mesh pattern to a more uniform appearance that is suitable for display applications under intensive lighting conditions.
2Reliability
If electrically conductive layers are made thicker to improve impedance and touch control, then touch control characteristics are improved, but visibility of patterns increases
Solution Approach 1:
The shadow eliminating layer serves as a mediator that decouples the relationship between conductor thickness and visibility. By introducing this intermediate layer, the system can maintain thicker electrically conductive layers for improved impedance and touch sensitivity without directly increasing pattern visibility, as the shadow eliminating layer masks the visual impact of the thicker conductive structure.
