EV Charging Enclosure Step Structure for Concealed Locking Part
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Charging devices for electric vehicles often have exposed eyebolts, which deteriorate the aesthetic design and require additional components for waterproofing, leading to increased work load.
Innovation Solution
A charging device design that incorporates a main body with a cable-connected charger, covered by a front door, side covers, and a rear cover, forming a step to conceal the eyebolt, and includes a water discharge passage to prevent moisture accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the eyebolt is exposed at the upper end of the charging device, then the locking part is accessible for moving the device, but the aesthetic design deteriorates
Solution Approach 1:
The locking part is nested within a stepped structure where the top surface of the main body is lower than the top surfaces of the front door, side covers, and rear cover. This nesting arrangement allows the locking part to be accessible while being visually concealed by the surrounding covers that form a higher plane, thus maintaining aesthetic design while preserving operational accessibility.
2Shape
If the eyebolt is removed to prevent aesthetic design reduction, then the appearance is improved, but additional components for waterproofing are required and work load increases
Solution Approach 1:
The locking part is nested within a stepped structure formed by the main body and surrounding covers. The top surface of the main body is intentionally lowered to create a step that conceals the locking part while the surrounding covers form a higher plane. This nested arrangement provides both aesthetic improvement and inherent waterproofing through the stepped structure, eliminating the need for additional waterproofing components.
3Shape
If a step is formed to conceal the locking part, then aesthetic design is improved, but water may accumulate in the step
Solution Approach 1:
A water discharge passage is extracted and incorporated into the stepped structure. This passage provides a dedicated pathway for water to drain from the step area, preventing water accumulation while preserving the aesthetic benefits of the stepped design that conceals the locking part.
4Shape
If the top surface of the main body is formed lower than surrounding covers, then the locking part is concealed, but water discharge becomes problematic
Solution Approach 1:
A water discharge passage is extracted and integrated into the stepped structure. This passage enables water to be discharged from the step area where the locking part is concealed, solving the water discharge problem while maintaining the aesthetic concealment provided by the lowered top surface of the main body.

AI summary
Disclosed is a charging device including a main body having a cable connected charger located therein, a front door covering a front surface of the main body and some of both side surfaces of the main body, a pair of side covers covering the rest of the both side surfaces of the main body, a rear cover covering a rear surface of the main body, and a locking part located at a top surface of the main body, wherein the top surface of the main body may be formed to be lower than a top surface of each of the front door, a pair of the side covers, and the rear cover so as not to expose the locking part.
