Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If traditional coupling devices are used, then axial installation space is reduced, but radial installation space is not optimized and deflection angle absorption is limited
Solution Approach 1:
The patent transitions from traditional axial alignment of coupling planes to a radial arrangement where multiple coupling planes are positioned at different radial locations. This dimensional change allows the coupling device to absorb deflection angles while optimizing both radial and axial space utilization, as the coupling planes can now accommodate angular misalignment in the radial dimension rather than requiring additional axial length.
2Adaptability or versatility
If multiple coupling planes are added to absorb deflection angles, then deflection capacity increases, but axial installation space increases
Solution Approach 1:
Instead of arranging multiple coupling planes axially (one after another along the axis), the patent positions them radially (at different distances from the center axis). This allows the coupling device to handle deflection angles by distributing coupling planes in the radial direction, thereby maintaining compact axial dimensions while achieving the required deflection absorption capability through radial spacing.
3Volume of moving object
If radial space is optimized for compact design, then axial space is reduced, but the ability to support joint devices in radial direction is insufficient
Solution Approach 1:
The supporting device is divided into multiple independent supporting elements arranged at different radial locations. Each supporting element can individually support a coupling plane, allowing the device to maintain compact overall dimensions while providing adequate support capability through the distributed segmented structure. This segmentation enables reliable support without requiring excessive radial or axial space.
