Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If extra components (microcontroller, CPU drivers, cables, connectors) are added to increase touch panel sensitivity or functionality, then touch panel functionality is improved, but device cost, size, and complexity increase
Solution Approach 1:
The existing touch panel hardware is made multi-functional by extending its sensing capability to the side edge of the device. The same capacitive sensing infrastructure (conductive lines, controller) serves both the main touch panel area and the side thumb sensor function, eliminating the need for separate sensor components and reducing device complexity while maintaining enhanced functionality
2Adaptability or versatility
If extra components (microcontroller, CPU drivers, cables, connectors) are added to increase touch panel sensitivity or functionality, then touch panel functionality is improved, but manufacturing cost increases
Solution Approach 1:
The invention reuses existing touch panel hardware components (conductive lines, controller) for the side sensor function, eliminating the need to manufacture and assemble additional separate sensor units, cables, and connectors. This multi-functional approach significantly reduces manufacturing costs while achieving enhanced touch functionality
3Adaptability or versatility
If extra components (microcontroller, CPU drivers, cables, connectors) are added to increase touch panel sensitivity or functionality, then touch panel functionality is improved, but device size increases
Solution Approach 1:
By making the existing touch panel hardware multi-functional and extending its sensing capability to the side edge, the invention avoids adding separate sensor components, cables, and connectors that would increase device volume. The same hardware infrastructure serves dual purposes, maintaining compact device size while enhancing functionality
