Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual positioning and adjustment of support points is used, then the support system can be operated without complex equipment, but the operation time is lengthy and positioning accuracy is low
Solution Approach 1:
The patent replaces manual mechanical adjustment with an automated control system that uses computer-aided design files and finite element analysis to calculate optimal support point positions. The control system automatically adjusts the height and angle of support devices based on calculated coordinates, eliminating manual positioning and significantly improving both accuracy and speed.
Solution Approach 2:
The system performs preliminary analysis by importing computer-aided design files and using finite element methods to calculate the optimal support point coordinates before actual positioning. This pre-calculation of support coordinates allows the system to achieve high positioning accuracy without time-consuming manual adjustments during the actual support process.
2Adaptability or versatility
If the same support points are used to support various workpieces, then the support system can be universally applied, but the workpiece deformation is large
Solution Approach 1:
The patent implements dynamic adjustability where the height and angle of each support device can be independently modified based on the specific workpiece geometry and material properties. The control system calculates optimal support coordinates for each workpiece type, allowing the same support system to adapt to different workpieces while minimizing deformation through precise, customized positioning.
Solution Approach 2:
The system applies local quality by calculating and applying different support parameters (height, angle, position) for each support point based on the local characteristics of the workpiece. The finite element analysis determines the specific support coordinates needed for each location, ensuring that each support point is optimally positioned for its local requirements rather than using uniform support points.
3Adaptability or versatility
If a large number of fixtures are used for diverse workpieces, then all workpieces can be supported, but the space requirement is huge and processing costs are high
Solution Approach 1:
The patent creates a universal support system where a single adjustable support device can serve multiple workpiece types through programmable control. The control system stores and processes computer-aided design files for different workpieces, allowing the same physical support apparatus to be reconfigured for various workpiece geometries and materials, eliminating the need for multiple dedicated fixtures.
Solution Approach 2:
The system changes parameters (support point coordinates, height, angle) based on the specific workpiece being supported rather than using fixed fixtures. The control system modifies these parameters dynamically according to the imported computer-aided design file, allowing one support system to handle diverse workpieces with varying requirements without physical reconfiguration or additional fixtures.

AI summary
An adjustable workpiece support system includes an adjustable support apparatus, an analysis support point module, a coordinate post-processing module and a control module. The adjustable support apparatus has a group of support devices for supporting a supported workpiece, the each support device being adjustable in height and angle. The analysis support point module is used to import a computer-aided design file of the supported workpiece, and analyze the computer-aided design file to obtain a group of support points of the supported workpiece. The coordinate post-processing module is configured to calculate the support coordinates of the each support device corresponding to the group of support points. The control module is configured to receive the support coordinates of the each support device, and adjust the height and angle of the each support device to support the supported workpiece, so that the amount of deformation of the supported workpiece is the minimum.
