Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the anchoring part uses a conventional structure, then the insertion force is large, but the mounting process becomes time-consuming and laborious
Solution Approach 1:
The anchoring part employs a dynamic rotation mechanism where the anchoring rod can rotate relative to the mounting hole during the fastening process. This dynamic motion transforms the insertion process from a purely linear forceful insertion to a rotational engagement, reducing the peak insertion force required while maintaining secure connection.
Solution Approach 2:
The anchoring part is segmented into functional components: the anchoring rod with locking notches, the head portion, and the elastic fins. The locking notches are positioned at specific locations on the anchoring rod to engage with the mounting hole at different stages, allowing the insertion process to be divided into insertion, rotation, and locking phases, thereby reducing overall insertion force requirements.
2Force
If the anchoring part uses a conventional structure, then the insertion force is large, but the mounting process becomes laborious
Solution Approach 1:
The rotation mechanism allows the anchoring rod to naturally orient itself during insertion, reducing the manual effort required by workers. The dynamic engagement of locking notches with the mounting hole creates a self-aligning effect that simplifies the mounting operation.
Solution Approach 2:
The anchoring part performs part of the mounting work automatically through its own structural features. The locking notches automatically engage with the mounting hole during rotation, and the elastic fins automatically provide locking action, reducing the need for manual intervention and making the mounting process easier.
3Strength
If the anchoring part has conventional anti-pulling structure, then the structure is simple, but the anti-pulling force is not large enough causing accidental dislodging
Solution Approach 1:
The anti-pulling mechanism utilizes the dynamic rotation capability of the anchoring rod. As the rod rotates during fastening, the locking notches engage with the mounting hole at optimal positions, creating a mechanical interlock that provides strong anti-pulling force. This dynamic engagement is more effective than static anchoring structures.
Solution Approach 2:
The locking notches are positioned asymmetrically on the anchoring rod at specific locations along its length. This asymmetric arrangement creates unequal engagement forces during rotation, with the notches engaging the mounting hole at strategically positioned points that maximize resistance to pulling forces while maintaining structural simplicity.
4Strength
If the anchoring part uses elastic fins extending from sidewalls, then the anti-pulling force is enhanced, but the insertion complexity increases
Solution Approach 1:
The elastic fins are strategically positioned at specific locations on the anchoring rod rather than uniformly distributed. This local placement provides enhanced anti-pulling force at critical positions where it is most needed, while minimizing the overall structural complexity and material usage. The fins are located to engage with the mounting hole during the rotation and fastening process.
