Distribution Box Circuit Board Layout for Drawer Cabinet Expansion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drawer-type power distribution cabinets face issues with dense and complex wire harnesses due to excessive secondary wires, leading to space occupation and difficulty in assembly, limiting the expansion of drawer assemblies.
Innovation Solution
A distribution box with a circuit board, first and second connection assemblies, and modular sockets that replace secondary wire harnesses, allowing for efficient signal and power transmission, reducing space occupation and assembly complexity, and enabling expansion of drawer assemblies.

Engineering Contradiction Analysis
1Productivity
If the number of drawer assemblies arranged in the same layer increases, then the power distribution capacity is improved, but the number of secondary wires increases, occupying more space and increasing assembly complexity
Solution Approach 1:
A circuit board is introduced as an intermediary component between the drawer assemblies and the distribution box. The circuit board provides integrated connection interfaces that replace the traditional wire harness system. Multiple drawer assemblies can be connected to the circuit board through standardized interfaces, eliminating the need for numerous individual secondary wires while maintaining the ability to distribute power to multiple drawers.
2Productivity
If the number of drawer assemblies arranged in the same layer increases, then the power distribution capacity is improved, but the space occupied by wire harnesses increases
Solution Approach 1:
Multiple wire connection functions are merged into a single circuit board component. Instead of having separate wire harnesses for each drawer assembly connection, the circuit board integrates all connection interfaces in one location. This consolidation dramatically reduces the volume occupied by wiring while enabling connection to multiple drawer assemblies.
3Productivity
If the number of drawer assemblies arranged in the same layer increases, then the power distribution capacity is improved, but the assembly difficulty increases
Solution Approach 1:
The system is segmented into modular components: drawer assemblies with standardized interfaces, a circuit board with integrated connection points, and a distribution box structure. This segmentation allows for pre-assembly and testing of individual components before final integration, significantly reducing assembly difficulty when scaling to multiple drawer assemblies.
