Rotating Charging Pile Cable Storage in a Compact Turntable Shell
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing charging piles are large and require fixed installation, with exposed cables that are prone to damage, and lack efficient storage solutions.
Innovation Solution
A compact charging pile design featuring a rotatable turntable with integrated wire winding groove, allowing the charging cable to be easily extended and retracted without additional driving mechanisms, enabling users to manually rotate the turntable for storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the charging pile uses a fixed structure with exposed cables, then the cable is easily accessible, but the cable is prone to damage and the overall volume is large
Solution Approach 1:
The patent employs a flexible wire winding groove structure that can rotate and retract, allowing the charging cable to be stored protected within the shell while remaining accessible during use. The groove acts as a flexible containment structure that protects the cable from damage while enabling easy retrieval.
2Quantity of substance
If the charging pile includes a wire winding groove, then the charging wire storage is improved, but the overall volume increases
Solution Approach 1:
The wire winding groove is nested within the charging pile shell structure, utilizing the internal space efficiently. The groove is integrated into the existing shell geometry rather than adding external protrusions, allowing cable storage without significantly increasing the overall volume of the charging pile.
Solution Approach 2:
The wire winding groove is designed to be rotatable rather than fixed, allowing it to dynamically adjust its position. When not in use, the groove can rotate to retract the cable completely into the shell, minimizing the external volume required. This dynamic mechanism allows the structure to adapt between storage and usage states.
3Device complexity
If the turntable is manually rotatable without driving devices, then the device complexity is reduced, but the ease of operation may be compromised
Solution Approach 1:
The turntable structure is segmented into discrete components including the rotating platform, wire winding groove, and connection elements. This segmentation allows each component to be optimized independently, with the groove specifically designed to rotate smoothly on the turntable without requiring complex driving mechanisms.
Solution Approach 2:
The wire winding groove structure itself provides the rotation mechanism through its geometric design and connection to the turntable. The groove is shaped and positioned such that it can rotate passively when force is applied to the charging cable or the groove edge, eliminating the need for external motors or actuators while still enabling easy operation.
