High-Voltage Box Tray Assembly for Easier Module Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation and maintenance of functional modules in high-voltage boxes for batteries are complicated due to the need for disassembly and replacement, which increases complexity.
Innovation Solution
A box body design with a housing, support, and tray assembly, where the tray assembly is movably disposed on the support, allowing functional modules to be moved between the inside and outside of the housing through a first opening, facilitated by slideways that guide and limit the movement of trays along different directions, enabling easy installation and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the functional module is fixed inside the housing, then the structural stability is improved, but the ease of repair deteriorates
Solution Approach 1:
The functional module is segmented from the housing structure through the movable tray assembly, allowing the module to be independently accessed and removed without disassembling the entire housing, thus maintaining structural stability while improving ease of repair
Solution Approach 2:
The tray assembly is designed to be movable rather than fixed, enabling dynamic access to the functional module. The tray can slide in and out along guideways, transforming the static fixation into a dynamic system that facilitates easy removal and installation for repair purposes
2Ease of repair
If the functional module is accessible through disassembly, then the ease of repair is improved, but the device complexity increases
Solution Approach 1:
The movable tray assembly serves multiple functions: it provides structural support for the functional module, enables easy access for repair, and facilitates installation and removal. This multi-functional design improves ease of repair without adding significant complexity, as a single mechanism achieves multiple objectives
3Ease of operation
If the tray assembly is movable, then the ease of operation is improved, but the friction increases
Solution Approach 1:
The gaps are strategically extracted and placed in specific sections of the slideway to reduce friction. By removing material to create gaps, the design reduces contact area and frictional forces, enabling smoother movement of the tray assembly while maintaining ease of operation
