Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical push buttons are used for control, then control signal generation is achieved, but mechanical structure wears out easily and becomes broken due to excessive pressing force
Solution Approach 1:
The patent replaces the mechanical push button system with an optical touch panel system. Instead of using physical buttons that mechanically press switches, the invention uses a touch-sensitive display that detects finger contact optically and electrically, eliminating mechanical wear and improving durability while maintaining ease of operation.
Solution Approach 2:
The patent incorporates LED lighting elements that change colors based on the touched zone, providing visual feedback to users. This color-changing feature enhances the user experience and operational feedback without requiring mechanical button structures.
2Adaptability or versatility
If light source with different colors is mounted in push buttons, then lighting display with different colors is achieved, but colors are fixed and cannot be changed or adjusted
Solution Approach 1:
The patent implements dynamic color control by allowing the LED lighting elements to change colors based on which touch zone is activated. The system transitions from static fixed-color lighting to dynamic color-changing lighting that adapts to user interaction, enhancing versatility without significantly increasing structural complexity.
Solution Approach 2:
The patent changes the color parameter of the LED lighting elements based on the touched zone. By varying the color temperature and hue of the LEDs according to the activated zone, the system achieves color customization and adaptability while maintaining a relatively simple overall structure.
3Ease of manufacture
If traditional push button mechanism is used, then control function is achieved, but fabrication cost increases due to complicated mechanic structure
Solution Approach 1:
The patent replaces the complicated mechanical push button structure with a simpler optical touch panel system. This substitution eliminates the need for mechanical springs, switches, and button assemblies, thereby reducing fabrication costs and improving structural durability simultaneously.
Solution Approach 2:
The patent creates a virtual representation of the push button function through optical and electrical sensing layers. Instead of using physical mechanical buttons, the system uses a touchscreen interface that replicates button functionality through software-controlled optical detection, reducing manufacturing complexity and cost.
