Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a polarization filter is used to reduce reflected light or scattered light, then the clarity of displayed information is improved, but the device complexity increases due to manual operation requirements
Solution Approach 1:
The patent applies the dynamics principle by transforming the static manual polarization filter into a dynamic electrically controllable system. The liquid crystal panel enables real-time adjustment of polarization angles through electrical signals, allowing the filter to adapt its orientation automatically based on ambient light conditions without requiring manual intervention. This resolves the contradiction by maintaining improved clarity while eliminating the complexity of manual operation.
Solution Approach 2:
The patent implements self-service through the image sensor and controller combination that automatically detects ambient light conditions and adjusts the polarization filter accordingly. The system serves itself by using the image sensor to monitor the display environment and autonomously controlling the liquid crystal panel to optimize polarization angles, eliminating the need for user intervention while maintaining optimal clarity under varying lighting conditions.
2Device complexity
If manual operation of polarization filter is used to set polarization angle, then the device complexity is reduced, but the productivity decreases due to time-consuming adjustment
Solution Approach 1:
The patent replaces the mechanical manual adjustment system with an electrical control system. Instead of physically rotating the polarization filter by hand, the system uses electrical signals to control the liquid crystal panel's molecular orientation, enabling rapid polarization angle changes through voltage application. This substitution maintains structural simplicity while dramatically increasing adjustment speed and productivity.
Solution Approach 2:
The patent applies parameter changes by controlling the electrical voltage applied to the liquid crystal panel to dynamically alter the polarization angle. By changing the voltage parameter, the system can rapidly adjust the polarization orientation without mechanical movement, achieving fast response times and high productivity while maintaining a simple overall device structure.
3Device complexity
If polarization filter is carried separately from camera, then the device complexity is reduced, but the ease of operation worsens due to additional carrying burden
Solution Approach 1:
The patent applies the merging principle by integrating the polarization filter functionality directly into the camera device. The liquid crystal panel and control system are incorporated within the camera body, combining what were previously separate devices into a single integrated unit. This eliminates the need to carry a separate polarization filter while maintaining full polarization capabilities, thereby improving ease of operation without significantly increasing overall device complexity.
Solution Approach 2:
The patent implements universality by designing the camera with built-in polarization control capabilities that serve multiple functions. The same liquid crystal panel system can adjust polarization angles for various shooting conditions, making the camera itself a universal device that eliminates the need for specialized external accessories. This multi-functionality improves usability convenience while keeping the integrated structure manageable.
