Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing arc locks are used to achieve angle adjustment, then angle adjustment within a certain range is realized, but the structure becomes complex and difficult to maintain
Solution Approach 1:
The arc adjuster is divided into multiple protrusions (nine protrusions uniformly arranged) along the circumferential direction, each capable of engaging with the adjusting rod at different angular positions. This segmentation allows discrete angle adjustment while maintaining a simple overall structure, resolving the contradiction between adjustment versatility and structural complexity.
Solution Approach 2:
The arc adjuster with multiple protrusions can achieve angle adjustment at nine different positions within a specific range, providing universal applicability for various angular requirements without needing multiple different lock structures. This multi-functional design enables a single device to replace what would otherwise require multiple specialized components.
2Manufacturing precision
If existing arc locks are customized to fit specific radian sizes, then precise angle adjustment is achieved, but universality is reduced and customization increases complexity
Solution Approach 1:
The arc adjuster is designed to be rotatable relative to the first shell, allowing dynamic adjustment between nine different angular positions defined by the protrusions. This dynamic capability enables the same structure to adapt to multiple precise angle requirements without customization, maintaining both precision and universality.
Solution Approach 2:
By changing the angular position of the protrusions on the arc adjuster, the locking angle can be varied between nine different values. This parameter change approach allows a single standardized component to provide precise angle adjustment for multiple applications, eliminating the need for customized locks for different radian sizes.
3Adaptability or versatility
If existing arc locks are designed for angle adjustment, then angle flexibility is improved, but the operation becomes difficult and maintenance complexity increases
Solution Approach 1:
The adjusting rod is inserted through the protrusions of the arc adjuster, with the chuck engaging into the groove on the protrusion. This nested arrangement allows smooth operation where the adjusting rod moves through defined paths, making angle adjustment intuitive and easy to perform while maintaining flexible angle changes.
Solution Approach 2:
The groove on the protrusion acts as an intermediary guide for the adjusting rod, ensuring smooth and controlled movement during angle adjustment. This intermediary feature simplifies the operation by providing a clear mechanical path, reducing the complexity of the adjustment process while maintaining angle flexibility.
4Measurement precision
If a rotatable arc adjuster with multiple protrusions is used, then angle adjustment precision is improved, but the number of components increases
Solution Approach 1:
Multiple functional elements are merged into the arc adjuster: the rotatable mechanism, the nine protrusions for angular positioning, and the grooves for locking engagement are all integrated into a single component. This merging provides precise angle adjustment capability without proportionally increasing the number of separate components, as the arc adjuster itself performs multiple functions.
