Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable management systems for electric vehicle charging stations, particularly for liquid-cooled cables, are difficult to maneuver and can damage cables due to tight clamping, posing accessibility issues and safety hazards.
Innovation Solution
A rotatable cable holder with a primary coupler featuring an exterior collar, a rigid portion with gripping features, and a compressible portion that allows the cable to rotate within a housing, preventing damage and improving maneuverability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional cable holders are used to secure liquid-cooled charging cables, then cable management is achieved, but cable flexibility and maneuverability are reduced
Solution Approach 1:
The cable holder incorporates a rotatable coupling mechanism that allows the cable to rotate freely within the holder while maintaining secure attachment. This dynamic feature enables the cable to change orientation and position as needed during charging operations, resolving the contradiction between stable cable management and operational flexibility.
2Strength
If tight clamping is applied to secure the cable, then cable holding strength is improved, but cable damage risk increases
Solution Approach 1:
The cable holder uses a compression element with adjustable clamping force that can be optimized for different cable types and sizes. By changing the compression parameters to match the specific cable being held, the system achieves secure attachment without excessive force that could damage the cable, particularly important for delicate liquid-cooled cables.
3Stability of the object's composition
If fixed cable positioning is used, then cable stability is maintained, but user accessibility is reduced
Solution Approach 1:
The rotatable coupling mechanism allows the cable to be easily repositioned and rotated to different angles while maintaining secure attachment. This enables users with disabilities or different height requirements to access the charging connector more easily, while the cable remains stably connected to the charging station throughout the charging process.
4Strength
If rigid cable support structures are used, then structural strength is improved, but cable flexibility is reduced
Solution Approach 1:
The cable holder uses a rotatable coupling mechanism that provides structural support through its rigid housing and mounting structure, while the rotating interface allows the cable to flex and change orientation freely. This separates the support function from the flexibility function, allowing both to coexist without compromise.

AI summary
A cable holder for manipulating liquid-cooled electric vehicle (EV) charging cables in EV charging stations. The cable holder includes a housing defining a primary interior slot and a primary coupler disposed therein. The primary coupler includes an exterior collar, a rigid portion, and a compressible portion. The exterior collar couples the primary coupler to the housing by engaging the primary interior slot, the exterior collar being rotatable within the primary interior slot. The rigid portion has gripping features for gripping a cable. The compressible portion is situated between the exterior collar and the rigid portion and couples the exterior collar to the rigid portion to allow the cable to rotate within the housing.
