Rotating Chamber Cable Guide for Electric Vehicle Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-capacity electric vehicle charging cables are rigid and thick, making it difficult to implement bending or winding solutions, and existing methods like lifting and dropping are inconvenient for managing cable length and exposure.
Innovation Solution
A rotating chamber system that automatically adjusts the charging cable length by rotating and reversing to wind or unwind the cable, changing modes based on the cable outlet position, using a rotating cylinder, disk, and power module to manage cable exposure and accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the charging cable is exposed for long periods to accommodate various electric vehicle types and parking position deviations, then the charging system can serve more vehicle types and positions, but the charging cable may touch the ground for long periods which is inconvenient and potentially hazardous
Solution Approach 1:
The patent applies the dynamics principle by implementing a rotating chamber that can automatically rotate and reverse-rotate to adjust the charging cable outlet position. This dynamic mechanism allows the system to adapt the cable exposure length automatically based on charging status, eliminating the need for manual cable management while maintaining adaptability to different vehicle types and parking positions.
2Length of moving object
If the charging cable is wound or bent in small circles to reduce exposure, then the cable length is reduced, but this solution cannot be applied to high-capacity charging cables because they are thick and rigid
Solution Approach 1:
The rotating chamber mechanism provides a dynamic solution that adjusts cable exposure through rotation rather than relying on cable flexibility. The chamber rotates to position the cable outlet appropriately, allowing rigid high-capacity cables to achieve the same effect as flexible cables would through winding or bending.
3Length of moving object
If the charging cable is lifted and dropped manually to adjust exposure, then the cable position can be adjusted, but it is inconvenient to drop the charging cable whenever charging and lifting up the cable after charging
Solution Approach 1:
The system implements self-service by automatically rotating the chamber to adjust cable exposure based on charging status. When charging is completed and the socket engages with the holding pocket, the chamber automatically reverse-rotates to wind the cable and reduce exposure, eliminating the need for manual lifting and dropping operations.
Solution Approach 2:
The system uses feedback from the charging socket engagement status to trigger automatic chamber rotation. The sensor detects when the charging socket is engaged with the socket holding pocket, and this feedback signal initiates the reverse rotation to wind the cable and transition to standby mode.
