Hexagonal Wrench Connection Device with Multi-Size Recesses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connection devices for multi-angular wrench sockets are prone to slippage and are not expandable, allowing engagement with only one flute, limiting their functionality.
Innovation Solution
A connection device comprising a first part with multiple hexagonal recesses of different sizes in both Metric and English systems, and a second part with corresponding recesses and protrusions, allowing secure engagement and rotation of hexagonal wrenches of various sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wrench is engaged with the flutes of the main body and the inner circumference of the first tubular body, then the wrench can be connected to the device, but the wrench can easily slip away from the flute
Solution Approach 1:
The patent applies local quality by providing different types of recesses (first recesses in the first part, second recesses in the second part) with different geometries and dimensions at specific locations. Each recess is designed to match specific wrench sizes, creating localized engagement zones that prevent slippage for corresponding wrench types while maintaining overall device functionality.
2Adaptability or versatility
If the main body is connected to the connecting section, then the device structure is formed, but the wrench can only be engaged with one of the flutes so that the function is not expandable
Solution Approach 1:
The patent implements universality by designing the connection device to accommodate multiple wrench sizes and types through the combination of first recesses (in the first part) and second recesses (in the second part). This multi-functional design allows a single device to serve multiple purposes - engaging with different wrench sizes, both Metric and English systems - without requiring separate tools for each size.
Solution Approach 2:
The patent applies segmentation by dividing the connection device into two separate parts: the first part with first recesses and the second part with second recesses. This segmentation allows each part to be optimized for specific wrench types while collectively providing comprehensive coverage of multiple wrench sizes. The parts can work together or independently, enhancing versatility without excessive complexity.
3Adaptability or versatility
If multiple hexagonal recesses of different sizes are provided, then the device can engage with different sizes of hexagonal wrenches, but the device structure becomes more complex
Solution Approach 1:
The patent divides the complex task of accommodating multiple wrench sizes into two manageable parts. The first part contains first recesses for certain wrench sizes, while the second part contains second recesses for other wrench sizes. This segmentation reduces the complexity of any single component while achieving the overall goal of multi-size compatibility.
Solution Approach 2:
The patent incorporates dynamic elements by making the first part rotatable relative to the second part around a central axis. This rotational capability allows the user to dynamically reposition the first part to access different recesses, providing adaptability without requiring all recesses to be simultaneously accessible in a static configuration, thereby reducing structural complexity.

AI summary
A connection device for a hexagonal wrench and includes a first part and a second part. The first part has an insertion section through which multiple hexagonal first recesses are defined, and an operation portion formed on one end thereof. The operation portion has multiple second hexagonal second recesses. The second part has a reception hole in which the insertion section is inserted and is positioned relative to the second part. The second part has an opening and the first recesses are exposed. The second part has another operation portion on one end thereof. The operation portion has multiple third hexagonal recesses. The first, second and third hexagonal recesses have different sizes and are Metric system and English system.
