Manual Tool Cable Connection for Handle Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand-operated processing devices require complex disassembly and tool usage to access the electrical plug connection, making it difficult to remove the handle housing body from the first housing body.
Innovation Solution
The electrical cable connection is designed with additional cable length that follows the movement of the handle housing body from the use position to the release position, allowing the electrical plug connection to be accessible in a transition area for finger-actuated detachment, eliminating the need to open the first housing body or use tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electrical plug connection is arranged inside the first housing body to be inaccessible from the outside, then the electrical connection is protected and secure, but the handle housing body cannot be easily removed without opening the first housing body and using tools
Solution Approach 1:
The electrical plug connection is moved from the interior of the first housing body to a transition area on the outer surface, changing its spatial dimension from internal to external accessibility. This allows the plug connection to be accessed without opening the housing body, enabling tool-free detachment of the handle housing body while maintaining electrical connection security through the transition area design.
2Ease of operation
If the electrical cable connection is made accessible for finger-actuated detachment, then the handle housing body can be easily removed, but the cable connection may obstruct the movement of the handle housing body from use position to release position
Solution Approach 1:
The electrical cable connection uses a flexible cable design that can bend and extend, allowing the handle housing body to move freely from the use position to the release position. The flexible cable accommodates the movement range while keeping the plug connection accessible in the transition area, eliminating obstruction during the detachment process.
3Ease of repair
If the electrical plug connection is placed in a transition area between the first housing body and handle housing body, then finger-actuated detachment is possible without tools, but the plug connection may be exposed to damage or accidental disconnection
Solution Approach 1:
The design requires the handle housing body to be moved to a specific release position before the electrical plug connection becomes accessible for detachment. This preliminary action of positioning ensures that intentional detachment is required, preventing accidental disconnection while still allowing easy tool-free removal when needed. The transition area placement combined with position-dependent accessibility balances security and ease of repair.
