Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a special wrench is used to rotate the push stopping ring and spring holder for adjustment, then the fastening effect is improved, but the ease of operation deteriorates due to requiring additional tools
Solution Approach 1:
The quick release handle enables the fastening device to be operated without external tools. By pivoting the handle between the first position (engaging the stuffing block with the threaded rod) and the second position (disengaging), the user can independently tighten or release the fastening mechanism, eliminating the need for special wrenches and achieving self-service operation.
Solution Approach 2:
The stuffing block acts as an intermediary element between the quick release handle and the threaded rod. When the handle is pivoted to the first position, it pushes the stuffing block to engage with the threaded rod, providing the fastening effect. This intermediary mechanism translates the simple pivoting motion into effective fastening without requiring complex tool interfaces.
2Reliability
If a special wrench is required for adjusting spring preload and shock absorber length, then the fastening effect is improved, but the device complexity increases due to requiring additional tools and procedures
Solution Approach 1:
The invention merges the adjustment function and fastening function into a single integrated mechanism. The quick release handle simultaneously performs both the adjustment locking and the fastening operations by pivoting to different positions, eliminating the need for separate wrench operations and reducing overall system complexity while maintaining reliable fastening.
Solution Approach 2:
The invention extracts the fastening function from the traditional wrench-based system and incorporates it directly into the adjustment mechanism itself. The quick release handle and stuffing block form a self-contained fastening subsystem that is integrated with the adjustment components, removing the dependency on external tools and simplifying the overall device structure.
3Reliability
If the positioning ring is rotated to be tightly abutted against the outer tube for fastening, then the fastening effect is improved, but the ease of operation deteriorates due to requiring special tools
Solution Approach 1:
The quick release handle enables the user to independently engage and disengage the fastening mechanism without external tools. By simply pivoting the handle between its two positions, the user can lock or release the positioning ring's engagement with the outer tube, achieving self-service operation and eliminating the need for special wrenches.

AI summary
A quick release fastening device includes a threaded ring and at least one fastening unit. The threaded ring includes a ring-shaped main body including an outer surface, an inner threaded surface defining a threaded hole, at least one groove located on the outer surface, and at least one radial through hole located in the groove and communicating with the threaded hole. The fastening unit includes a stuffing block disposed in the radial through hole, movable along the radial direction of the threaded hole and including a threaded surface facing toward the threaded hole, and a quick release handle pivotably connected with the threaded ring and located in the groove for pushing the stuffing block toward the threaded hole when being pivoted from a release position to a tightly press position. The quick release fastening device is simple in structure, convenient in usage and great in fastening effect.
