Puncture Repair Kit Cable Winding Tool
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional puncture repair kits face difficulties in storing the power cable due to its length, which complicates compact storage within the vehicle, necessitating a solution to enhance storability without increasing the kit's size.
Innovation Solution
Incorporating a winding-up tool that bundles the power cable into a predetermined shape, with a holding portion for the connection terminal, allowing easy storage and preventing the tool from being misplaced during use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the storage portion capacity is increased to store the power cable, then the power cable storability is improved, but the puncture repair kit size increases
Solution Approach 1:
The winding-up tool is integrated into the housing by storing it within a storage portion, creating a nested structure where the tool is contained within the kit housing. This allows the cable management functionality to be incorporated without significantly increasing the overall kit volume.
Solution Approach 2:
The power cable is wound around the winding-up tool in a circular/coiled configuration, transforming the cable from a linear extended state to a compact three-dimensional coil. This dimensional transformation enables the long cable to be stored in a small space without increasing the kit's external dimensions.
2Ease of operation
If a winding-up tool is added to bundle the power cable, then the power cable management is improved, but the device complexity increases
Solution Approach 1:
The winding-up tool is designed to be manually operated by the user themselves. The user simply winds the cable around the tool, eliminating the need for automated winding mechanisms, motors, or complex control systems. This self-service approach provides effective cable management while keeping the device structure simple.
Solution Approach 2:
The winding-up tool is designed as a detachable component that can be separated from the housing. This segmentation allows the tool to be independently manufactured and assembled, simplifying the overall device structure and making maintenance easier while still providing complete cable management functionality.
