Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If pressure sensors are arranged at five positions corresponding to fingers on a pad surface, then the device can detect holding force, but detection accuracy of pressurizing force is insufficient
Solution Approach 1:
The pad surface is divided into multiple regions, with pressure-sensitive detection regions arranged at vertex positions of polygons in each region. This segmentation allows distributed detection across the surface, improving overall detection accuracy without requiring a single complex sensor arrangement.
Solution Approach 2:
The invention transitions from linear or simple grid arrangements to polygonal vertex arrangements in multiple regions. By utilizing the two-dimensional surface more effectively through polygon geometry, the detection coverage and accuracy are enhanced while maintaining a systematic layout.
2Adaptability or versatility
If a spherical base is used to allow various grasping ways, then versatility of operation is improved, but device complexity increases
Solution Approach 1:
The base is designed with a spherical shape, allowing users to grasp and operate the device in multiple ways. The spherical geometry provides ergonomic flexibility and adaptability to different hand positions and grasping styles, enhancing user versatility.
3Measurement precision
If multiple plates cover the entire base surface with pressure-sensitive regions, then detection coverage is improved, but manufacturing complexity increases
Solution Approach 1:
The base surface is divided into multiple regions, each covered by a plate containing pressure-sensitive detection regions at polygon vertex positions. This segmentation enables modular manufacturing of plates while achieving comprehensive detection coverage across the entire surface.
Solution Approach 2:
Each plate is designed with pressure-sensitive detection regions specifically positioned at the vertex positions of polygons within its coverage area. This local optimization ensures that each plate contributes effectively to overall detection accuracy while maintaining manufacturing simplicity through standardized designs.
