Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different drive rods are replaced for different types of fasteners, then the tool can adapt to various fasteners, but the ease of operation deteriorates due to frequent replacements
Solution Approach 1:
The connector body is designed with a universal interface that can accommodate multiple types of drive rods through a single standardized connection mechanism. The through hole and blocking member configuration allows one connector body to work with various fastener types, eliminating the need to replace the entire tool for different applications.
Solution Approach 2:
The tool is divided into separable components: a connector body and interchangeable drive rods. The drive rods can be independently replaced while the connector body remains stationary, allowing users to switch between different fastener types by only changing the drive rod portion rather than the entire tool.
2Device complexity
If the sleeving hole is a blind hole closed at one end, then the structure is simpler, but the adaptability deteriorates because there is no space for receiving convex portions of objects
Solution Approach 1:
Instead of making the sleeving hole a blind hole closed at one end, the invention inverts the approach by creating a through hole that extends completely through the connector body. This allows the hole to receive convex portions of objects from either direction while maintaining structural simplicity.
Solution Approach 2:
The blocking member is positioned within the through hole such that it can be urged outwardly by the adapter member while still allowing the through hole to receive convex portions of objects. The blocking member acts as a nested element that can be displaced to accommodate different object configurations.
3Ease of manufacture
If the stepped portion is perpendicular to the axial direction, then the manufacturing is simpler, but the stability deteriorates because the elastic member cannot be guided and centered
Solution Approach 1:
The stepped portion is designed with an asymmetric configuration where the first stepped portion has a different radial position than the second stepped portion. This asymmetric arrangement creates a guiding path that naturally centers and guides the elastic member along the axial direction, improving positioning stability while remaining manufacturable.
Solution Approach 2:
The stepped portions are arranged at different radial distances from the axial direction, creating a multi-dimensional guiding structure. This dimensional arrangement allows the elastic member to be guided and centered through the interaction of multiple stepped surfaces rather than relying on a single perpendicular step.

AI summary
A tool connector is provided, including: a main body, including a connection portion including a through hole, a blocking member being movably received in the through hole; an adapter member, inserted in the main body and movable between first and second positions, wherein when located in the first position, the adapter member is abutted against the blocking member so that the blocking member is urged outwardly, when the adapter member is located in the second position, the blocking member is not urged outwardly by the adapter member so that the blocking member is inwardly movable, and the adapter member further includes a connection hole; an elastic member, disposed between the main body and the adapter member, urging the adapter member toward the first position; at least one detent member, disposed on the main body, configured to block the adapter member from detaching from the main body.
