VSEngineering Contradiction Analysis

1Reliability

If copper bars are extensively used for connecting power distribution components in a cabinet body, then reliable current conduction is achieved, but the internal structure becomes complex, assembly time increases, and costs increase

Engineering Contradiction:
Improvecurrent conduction reliabilityVSAvoidinternal structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The power distribution system is segmented into modular units, each with integrated copper bars. This segmentation reduces the overall complexity by breaking down the extensive copper bar network into manageable, pre-assembled modules that can be independently handled and installed.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The copper bars are merged with the power distribution components to form integrated modules. By combining the copper bars with the power distribution units during manufacturing, the system reduces the number of separate connection steps required during assembly, thereby simplifying the internal structure and reducing assembly time while maintaining reliable current conduction.

Inventive Principle:

Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The copper bars are pre-assembled and integrated with the power distribution components during manufacturing before the modules are installed in the cabinet. This preliminary action ensures that current distribution connections are already established and tested, eliminating the need for time-consuming on-site assembly and connection work.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

By merging the copper bars with power distribution components into integrated modules, the system reduces the number of separate assembly steps. The modules are designed to be installed as complete units, thereby reducing assembly time while ensuring reliable current distribution throughout the system.

Inventive Principle:

Solution Approach 1:

The power distribution system is divided into modular units, each containing integrated copper bars. This segmentation allows for optimized copper usage within each module, ensuring complete power distribution is achieved within the module while reducing the total quantity of copper bars needed for the entire system compared to extensive point-to-point connections.

Inventive Principle:
