Cabinet Reinforcing Member Design for Structural Rigidity Under Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric vehicle charging cabinets face structural rigidity issues during movement, leading to potential damage due to applied loads, and there are limitations in expanding installation space for these facilities.
Innovation Solution
A cabinet design with reinforcing members coupled to the inner surface, featuring a horizontal and vertical arrangement of reinforcing members, including lateral, top, bottom, intermediate, and additional reinforcing members, to enhance structural rigidity and distribute load, while also incorporating a rear-mounted exhaust structure to reduce cabinet size and improve aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cabinet is designed as a box-shaped structure for mounting electronic components, then it can accommodate power modules and charging facilities, but the cabinet becomes vulnerable to bending and twisting under load during movement
Solution Approach 1:
The cabinet body is divided into an outer shell and an inner reinforcing frame structure. The reinforcing frame is segmented into multiple reinforcing members (first reinforcing member at the front, second reinforcing member at the rear, and third reinforcing members on lateral sides) that are spatially separated and connected, creating a segmented load-bearing structure that prevents bending and twisting while accommodating electronic components.
2Strength
If reinforcing members are added to increase structural rigidity, then the cabinet can resist damage during movement, but the device complexity increases
Solution Approach 1:
The reinforcing members are merged with the outer shell to form an integrated cabinet structure. The reinforcing frame is coupled to the inner surface of the outer shell, combining the protective function of the shell with the load-bearing function of the reinforcing members into a unified structural system that resists damage during movement without requiring separate reinforcement components.
3Volume of moving object
If the cabinet size is reduced to optimize installation space, then installation flexibility improves, but the structural rigidity may be compromised
Solution Approach 1:
The reinforcing members are arranged in a three-dimensional spatial configuration with specific spacing relationships (first reinforcing member at the front, second at the rear, third members on lateral sides). This spatial arrangement creates a rigid framework that maintains structural integrity even when the overall cabinet dimensions are reduced for optimized installation space.

AI summary
A cabinet includes a case having an accommodation space formed therein and having an open front, and a reinforcing member coupled to an inner surface of the case and configured to increase structural rigidity of the case, wherein the reinforcing member includes a pair of lateral reinforcing members arranged upright and spaced apart from each other in a first direction, a top reinforcing member disposed at an upper end of the pair of lateral reinforcing members, and a bottom reinforcing member disposed at a lower end of the pair of lateral reinforcing members and increases the structural rigidity of the case through a reinforcing member coupled to an inner surface of the case.
