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 wire storage solutions.
Innovation Solution
A compact charging pile design featuring a rotatable turntable with integrated wire winding groove, allowing the charging wire to be easily extended and retracted without additional driving mechanisms, enabling users to manually rotate the turntable for wire storage within the pile.
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 charging pile becomes large and the cable is prone to damage
Solution Approach 1:
The charging cable is nested within the charging pile body through a cable storage chamber. The cable can be extended when needed and retracted into the protective housing when not in use, reducing the exposed cable length and protecting the cable from damage while maintaining accessibility.
Solution Approach 2:
The charging pile incorporates a rotatable turntable mechanism that allows dynamic adjustment of the cable storage chamber orientation. This enables the cable to be smoothly extended and retracted while the turntable rotates, providing both cable protection and ease of operation without requiring a large fixed structure.
2Quantity of substance
If the charging pile includes a turntable with wire winding groove, then the wire storage efficiency improves, but the structural complexity increases
Solution Approach 1:
The turntable mechanism is merged with the cable storage chamber and the charging pile body. The turntable serves multiple functions: it supports the cable winding groove, enables cable extension/retraction, and integrates with the electric control assembly mounting. This consolidation reduces overall structural complexity while maintaining efficient wire storage capacity.
Solution Approach 2:
The turntable is designed as a multi-functional component that simultaneously provides mechanical support for the cable storage, enables rotational movement for cable deployment, and serves as a mounting base for the electric control assembly. This multi-functionality reduces the need for separate components, thereby reducing structural complexity while improving wire storage efficiency.
3Device complexity
If the charging pile uses manual turntable rotation, then additional motors are eliminated, but the ease of operation requires user physical effort
Solution Approach 1:
The turntable mechanism is designed to be manually operated by the user through direct rotation or by pulling the cable, which naturally drives the turntable to rotate and deploy or retract the cable. This self-service approach eliminates the need for additional motors or complex automated driving mechanisms while keeping the operational effort minimal through proper mechanical design.

AI summary
The present application relates to a charging pile, comprising a shell, a turntable, at least one electric control assembly and at least one charging gun, wherein the shell encloses and forms an inner cavity, two through holes are provided along the transverse or longitudinal direction of the shell, at least part of the turntable is rotatably arranged in the inner cavity along the axial direction of the through holes, at least one accommodating space is formed inside the turntable, and the electric control assembly is arranged in the accommodating space and can rotate with the turntable; the turntable comprises a first connecting portion and a second connecting portion, wherein the first connecting portion and the second connecting portion are respectively movably connected at the corresponding shell position of the two through holes; the first connecting portion and the second connecting portion cooperate to form at least one wire winding groove for accommodating a charging wire on the charging gun. The charging pile is designed by the movable fit between the turntable and the shell, the structural connection between the first connecting portion and the second connecting portion, and the position where the electric control assembly is arranged in the accommodating space, so as to reduce the overall volume of the charging pile and meet the storage requirement of the charging wire.
