Quick-Release Shaft With Nested Rotating Handle Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional quick-release structures fail to securely store rotating handles, leading to forgotten or lost storage locations over time.
Innovation Solution
A quick-release structure with a shaft and driving assembly, featuring a receiving hole and connecting hole, where the rotating handle is pivotally connected to the connecting rod and can be hidden within a recessed receiving hole when not in use, utilizing O-rings for secure positioning and an end cap for easy retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the rotating handle is stored separately from the quick-release structure, then the rotating handle can be easily accessed, but the user may forget the storage location or lose the rotating handle
Solution Approach 1:
The patent merges the rotating handle storage function with the quick-release structure by providing a receiving hole in the shaft. The rotating handle can be inserted into and stored within the quick-release structure itself, combining two previously separate functions (handling and storage) into one integrated system, thereby preventing loss while maintaining accessibility
Solution Approach 2:
The rotating handle is nested within the receiving hole of the shaft when not in use. The handle fits inside the hollow space of the shaft, creating a nested configuration where the smaller component (handle) is stored within the larger component (shaft), ensuring the handle remains attached to the quick-release structure
2Ease of operation
If the rotating handle is always exposed, then it is easily accessible, but it may be accidentally touched and loosen the shaft
Solution Approach 1:
The patent extracts the rotating handle from its always-exposed position and provides a dedicated receiving hole for storage. The handle can be removed from the engaged position and stored in the receiving hole, separating the handle from positions where it could accidentally contact and loosen the shaft, while still being easily retrievable when needed
3Reliability
If a receiving hole is added to store the rotating handle, then the rotating handle can be securely stored, but the device complexity increases
Solution Approach 1:
The shaft is given multiple functions: it serves as both the structural component of the quick-release mechanism and as a storage container for the rotating handle via the receiving hole. This multi-functionality adds the storage capability without requiring a completely separate storage mechanism, thereby limiting the increase in overall device complexity

AI summary
A quick-release structure includes a shaft and a driving assembly. Two ends of the shaft have a receiving hole and a connecting hole, respectively. The driving assembly includes a rotating handle and a connecting rod. One end of the rotating handle is provided with an end cap. The connecting rod includes a pivoting end and a driving section. The rotating handle is pivotally connected to the pivoting end of the connecting rod so that the rotating handle can be pivoted relative to one side of the connecting rod. When in use, the driving section is engaged in the connecting hole, and the rotating handle can be turned to drive the shaft to rotate; when not in use, the driving assembly is inserted into the receiving hole, and the end cap is pressed against an outer end of the receiving hole to be positioned.
