Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a shielding film with independently controllable transparency areas is used, then visibility and functionality are improved, but device complexity increases
Solution Approach 1:
The shielding film is divided into multiple independently controllable areas with separate conductive layers and partition portions, allowing each area to be controlled individually for enhanced visibility and functionality
Solution Approach 2:
The shielding film transitions from a static structure to a dynamic one where transparency and opacity can be changed in real-time through electrical signals applied to different areas, enabling adaptive visibility control
2Ease of operation
If partition portions are added to divide conductive layers into multiple areas, then transparency control is improved, but manufacturing complexity increases
Solution Approach 1:
The conductive layers are segmented into multiple areas by non-conductive partition portions, enabling independent control of transparency in different regions while maintaining a systematic manufacturing approach
Solution Approach 2:
Non-conductive partition portions serve as intermediary elements that divide the conductive layers into separate controllable areas, facilitating transparency control without requiring complex direct connections
