Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional control system with multiple motors is used to control the movement of the reflective panel and cover, then the display device can achieve precise control of panel movement, but the device complexity and manufacturing cost increase significantly
Solution Approach 1:
The patent combines the control functions of the reflective panel movement and cover movement into a single integrated control system. The control unit controls the driving means which moves the reflective panel, and simultaneously controls the cover to open or close based on the panel position, eliminating the need for separate motor controls for each component.
Solution Approach 2:
The single control unit performs multiple functions: it controls the driving means for panel movement, monitors panel position through detection means, and simultaneously controls the cover movement. This multi-functional approach reduces the overall number of control components while maintaining precise control over all moving parts.
2Ease of operation
If multiple motors and control mechanisms are installed to manage panel and cover movement, then the display device can operate smoothly, but the device size increases and manufacturing cost rises
Solution Approach 1:
The patent merges multiple control mechanisms into a single integrated system where one control unit manages both the reflective panel movement and cover movement. This consolidation reduces the number of motors and control components, thereby decreasing the overall device volume while maintaining smooth operation.
Solution Approach 2:
The cover movement is controlled automatically based on the reflective panel position detected by the detection means. When the panel moves to a predetermined position, the control unit automatically opens or closes the cover without requiring additional independent control mechanisms, reducing device complexity and size.
3Adaptability or versatility
If a complex control system with multiple motors is used, then the display device can control each part independently, but the manufacturing cost increases
Solution Approach 1:
The single control unit provides independent control capability for both the reflective panel and cover through its multi-functional design. It can control the driving means for panel movement and simultaneously control the cover movement based on panel position, maintaining versatility while reducing manufacturing cost by eliminating redundant control components.
Solution Approach 2:
The detection means monitors the reflective panel position and provides feedback to the control unit, which then independently controls the cover movement accordingly. This feedback mechanism enables independent control of each component using a single control unit, maintaining adaptability while simplifying the overall control system and reducing manufacturing cost.
