Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If semi-transparent coating lenses or perforated opaque lenses are used to display images on glasses, then image display capability is improved, but the wearer's vision is interfered with
Solution Approach 1:
The patent uses liquid crystal panels that can dynamically change their optical properties (transparency, reflectivity, polarization state) to display images only when needed, while maintaining clear vision when the display function is not required. This dynamic parameter change resolves the contradiction between image display capability and vision interference.
Solution Approach 2:
The system employs electrically controllable liquid crystal components that can switch between different states (transparent, reflective, polarized) based on control signals. This dynamic controllability allows the glasses to adapt between displaying images and maintaining clear vision, eliminating the static trade-off in traditional approaches.
2Ease of manufacture
If semi-transparent coating lenses or perforated opaque lenses are used, then static images can be displayed, but dynamic image changing capability is lost
Solution Approach 1:
The liquid crystal panels are electrically controlled to dynamically change their optical properties in response to control signals, enabling real-time image updates and transitions between different display states. This provides both static image stability and dynamic image changing capability simultaneously.
Solution Approach 2:
The liquid crystal panel system serves multiple functions: displaying static images, displaying dynamic images, controlling polarization states, and adjusting transparency. This multi-functionality resolves the contradiction between static image display capability and dynamic image changing capability.
3Adaptability or versatility
If liquid crystal panels with active matrix are used to control polarization state and display content, then dynamic display capability is improved, but device complexity increases
Solution Approach 1:
The patent integrates multiple functions (polarization control, image display, transparency adjustment) into a single liquid crystal panel system with active matrix control. This merging of functions reduces the number of separate components needed, thereby managing device complexity while maintaining dynamic display capability.
Solution Approach 2:
The active matrix liquid crystal panel performs multiple operations simultaneously: controlling polarization states for vision protection, displaying dynamic images, and adjusting transparency. This multi-functionality achieves dynamic display capability without proportionally increasing device complexity.
