Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If side pressure-sensing buttons are used, then the device structure is simple, but the sensing area is limited and control modes are restricted
Solution Approach 1:
The pressure sensing assembly is integrated directly into the display screen structure, merging the display function with the pressure sensing function. This eliminates the need for separate side pressure buttons while providing a larger sensing area across the entire display surface.
Solution Approach 2:
The pressure sensing capability is extended from the traditional one-dimensional side button to the two-dimensional display screen surface. The stacked deformation members enable pressure detection across the entire screen area, transforming the sensing interface from edge-only to full-surface detection.
2Adaptability or versatility
If side pressure-sensing buttons are used, then the manufacturing process is simple, but the control modes that can be realized are limited
Solution Approach 1:
The pressure sensing assembly integrated into the display screen enables multiple control modes including pressure detection, touch location identification, and various interaction gestures. The same structure supports diverse applications such as volume control, screenshot capture, and app switching, providing universal control functionality across different scenarios.
3Area of stationary object
If the pressure sensing assembly is integrated into the display screen, then the sensing area and control modes increase, but the structural complexity increases
Solution Approach 1:
The pressure sensing assembly采用 stacked deformation members (first deformation member, second deformation member, and supporting member) arranged in layers within the display screen thickness. This nested arrangement allows the pressure sensing function to be embedded within the existing display structure without significantly increasing the overall device volume or external dimensions.
