Replaceable Tool With Detent Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hand tools with a single-piece main body and working head are inflexible and require multiple tool types and sizes, leading to high costs, weight, and space usage, while assembled tools are inconvenient and labor-intensive to replace.
Innovation Solution
A replaceable tool design featuring a main body with a connecting hole and a control member that moves between locked and release positions, using a detent member to securely hold or release a replaceable member, allowing quick and easy tool bit or extension rod changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the main body and working head are formed of one piece, then the structural strength is good, but it is not suitable for various different specifications and operation requirements, resulting in high cost and weight
Solution Approach 1:
The tool is divided into a main body and a replaceable working head connected through a connecting hole and control member mechanism. The working head can be segmented and replaced according to different specifications and operation requirements, allowing one main body to serve multiple functions while maintaining structural strength through the robust connecting interface.
Solution Approach 2:
The main body is designed with a universal connecting hole and control member mechanism that can accommodate different types and sizes of working heads. This multi-functional design allows a single main body to perform various tasks by simply changing the working head, eliminating the need for multiple separate tools.
2Adaptability or versatility
If the main body and working head are assembled by a bolt and a nut, then various different specifications can be accommodated, but it has to disassemble and assemble bolt and nut in each replacement, which is inconvenient and time-consuming
Solution Approach 1:
The control member is extracted as a separate, movable component within the main body that independently controls the connection between the working head and main body. By taking out the control mechanism from the traditional bolt-nut assembly, the patent enables quick release and locking without requiring manual disassembly and assembly of fasteners.
Solution Approach 2:
The control member is designed to be movable between different positions (locked and unlocked) allowing dynamic control of the working head connection. This dynamic mechanism enables rapid switching between different working heads by simply moving the control member, eliminating the static and time-consuming bolt-nut assembly process.
3Adaptability or versatility
If multiple tools of different types and sizes are prepared, then various different specifications and operation requirements can be met, but it results in high cost and weight, and occupies more space
Solution Approach 1:
The main body is designed as a universal platform with a standardized connecting hole and control member mechanism that can accommodate multiple types and sizes of working heads. This allows a single main body to replace multiple specialized tools, reducing overall weight and storage space while maintaining the ability to meet various specifications and operation requirements.
4Adaptability or versatility
If multiple tools of different types and sizes are prepared, then various different specifications and operation requirements can be met, but it occupies more space
Solution Approach 1:
The main body serves as a compact universal platform that can hold different working heads. By consolidating multiple tool functions into one main body with interchangeable working heads, the overall volume and storage space required are significantly reduced compared to keeping multiple separate tools.

AI summary
A replaceable tool is provided, including: a main body, including a connecting hole extending along a first axis; a control member, inserted within the main body and including a detent member, being movable between a locked position and a release position along a second axis lateral to the first axis; wherein when the control member is located in the locked position, the detent member radially protrudes within the connecting hole; when the control member moves from the locked position to the release position, the detent member is away from the first axis.
