Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a deformable controller with grid projection is used to map complex deformations to input signals, then measurement precision is improved, but device complexity increases
Solution Approach 1:
A grid pattern is projected onto the inner surface of the deformable sphere as an intermediary reference framework. This grid serves as a mediator between the physical deformation and the sensor measurements, enabling precise mapping of complex deformation patterns through coordinate transformation and distortion analysis
Solution Approach 2:
Traditional mechanical sensors embedded in the controller are replaced with an optical sensing system. A projector displays a grid pattern on the inner surface, and cameras capture images of this grid. The deformation is measured by analyzing grid distortion in the captured images, substituting mechanical measurement with optical field-based measurement
2Measurement precision
If multiple sensors are positioned to image the grid for capturing deformation data, then measurement precision is improved, but device complexity increases
Solution Approach 1:
Multiple cameras are positioned at different locations within the controller to capture images of the grid from various angles. These multiple sensor inputs are merged and processed together to comprehensively analyze the three-dimensional deformation patterns of the sphere, improving measurement accuracy through multi-perspective data fusion

AI summary
A resilient deformable sphere includes a laser projector positioned to project a grid onto the inner surface of the sphere and a camera positioned to image the grid. When the sphere is deformed, the grid is distorted. Distortions in the grid are mapped to input signals to a computer simulation or other computer program.
