Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a force sensing function is added to an existing display device, then the functionality and user convenience are improved, but the weight and volume of the display device increase
Solution Approach 1:
The force sensing layer is integrated directly into the display panel structure, merging the force sensing function with the existing display components. This combination eliminates the need for separate force sensing modules, thereby adding functionality while minimizing increases in weight and volume.
Solution Approach 2:
The display panel is designed to serve multiple functions: displaying images and sensing force. By making the display panel itself force-sensitive through the inclusion of a force sensing layer, the device achieves multi-functionality without requiring additional dedicated components for force sensing.
2Adaptability or versatility
If a force sensing function is added to an existing display device, then the functionality is improved, but the structural complexity increases
Solution Approach 1:
The force sensing layer is merged with the display panel's existing layered structure. By integrating the force sensing functionality into the current panel architecture rather than adding a separate sensing system, the structural complexity is minimized while still achieving the desired multi-functional capability.
3Measurement precision
If buffer material with higher elastic coefficient than protrusion is used, then the force sensing precision is improved, but the manufacturing complexity increases
Solution Approach 1:
The patent specifies particular elastic coefficient ranges for the buffer material and protrusion to optimize force sensing precision. By defining specific parameter ranges (buffer material elastic coefficient greater than protrusion elastic coefficient), the patent achieves improved measurement precision while maintaining manufacturability through clear material selection criteria.
