Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional touch screen technologies are used, then reliable user input is achieved, but versatility and scalability are limited
Solution Approach 1:
The touch screen is divided into discrete functional elements using individual microchips embedded in the coating. Each microchip can be independently activated through RFID or capacitance sensing, allowing selective activation of specific regions while maintaining overall system reliability. This segmentation enables versatile configurations without compromising the reliability of individual touch points.
Solution Approach 2:
The patent employs universal microchip components that can function across multiple touch screen configurations and surfaces. The same RFID-sensitive or capacitance-sensitive microchips can be applied to various substrates (walls, desks, vehicles) and configured for different applications, achieving both versatility and consistent reliable performance through standardized multi-functional elements.
2Adaptability or versatility
If traditional touch screen technologies are used, then user input functionality is provided, but cost-effectiveness and scalability are reduced
Solution Approach 1:
The patent changes the fundamental parameters of touch screen construction by using sprayable or brushable coating materials containing microchips instead of traditional rigid panel assemblies. This allows the same base coating material to be scaled to different sizes and configurations, reducing manufacturing costs while maintaining scalability from small to large touch interfaces across various applications.
Solution Approach 2:
The patent utilizes inexpensive microchip components embedded in disposable or replaceable coating materials. Rather than investing in expensive permanent touch screen installations, users can apply affordable coated surfaces that can be easily replaced or reconfigured, achieving cost-effectiveness and scalability simultaneously.
3Adaptability or versatility
If microchips are applied in coating for touch screen, then flexibility and scalability are improved, but manufacturing complexity increases
Solution Approach 1:
The patent merges the microchip embedding process with standard coating application methods. The microchips are incorporated into the coating matrix before application, combining what would otherwise be separate manufacturing steps (chip placement and coating application) into a single integrated process, thereby reducing manufacturing complexity while maintaining flexibility.
Solution Approach 2:
The coating material itself serves the dual function of both adhesive and microchip carrier. The coating application process automatically positions and secures the microchips as it is applied to the surface, eliminating the need for separate microchip placement and alignment operations, thus reducing manufacturing complexity while preserving flexibility.
