Distribution Box Circuit Board Layout for Dense Wiring Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drawer-type power distribution cabinets face issues with dense and complex wire harnesses due to excessive wire connections, leading to difficulty in assembling the wire harnesses, which seriously occupy the space inside the distribution box. The difficulty of assembling the wire harnesses is high, and the expansion of the number of drawer assemblies is also limited.
Innovation Solution
A distribution box with a circuit board and connection assemblies that replace dense secondary wire harnesses, reducing space occupation and assembly difficulty, and allowing for more drawer assemblies by integrating digital and network interfaces with modular sockets and busbars.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of drawer assemblies arranged in the same layer increases, then the power distribution capacity is improved, but the number of wires for control loops increases excessively, forming dense and complex wire harnesses that occupy space and increase assembly difficulty
Solution Approach 1:
The patent replaces the mechanical wire harness system with an optical communication system. Specifically, it uses optical modules to transmit control signals and data between the distribution box and drawer assemblies, substituting the traditional electrical wire connections. This eliminates the need for complex wire harnesses while maintaining communication functionality, directly resolving the contradiction between increasing power distribution capacity and avoiding wire harness complexity.
Solution Approach 2:
The patent extracts the control loop wires from the main loop wire harnesses. By separating control signals into dedicated optical communication channels, the patent removes the burden of excessive control wires from the traditional wire harness system, reducing overall complexity while allowing more drawer assemblies to be connected.
2Adaptability or versatility
If the number of drawer assemblies arranged in the same layer increases, then the power distribution capacity is improved, but the space inside the distribution box is seriously occupied by dense wire harnesses
Solution Approach 1:
The patent replaces the space-consuming wire harness system with compact optical modules. The optical modules occupy significantly less space within the distribution box compared to extensive wire harnesses, enabling more drawer assemblies to be accommodated in the same layer without increasing space occupation.
3Adaptability or versatility
If the number of drawer assemblies arranged in the same layer increases, then the power distribution capacity is improved, but the difficulty of assembling the wire harnesses increases
Solution Approach 1:
The patent replaces the difficult-to-assemble wire harness system with plug-and-play optical modules. The optical modules come pre-configured with connection interfaces that simplify the assembly process, eliminating the need for complex wire routing and connection tasks that become increasingly difficult as more drawer assemblies are added.
