Solution Overview

Problem

Conventional distribution board systems require large spaces for air insulation, leading to increased production costs, power transmission path lengths, and heat generation, while also limiting adjustability and safety during maintenance.

Innovation Solution

The distribution board system incorporates a busway configuration arranged outside the chassis, featuring bridge switches and distribution devices that provide better insulation, reduced space requirements, and improved expandability and safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If copper strips or copper bars are used for power transmission inside the chassis, then the distribution board system can be compact, but the required air insulation space increases and production cost increases

Engineering Contradiction:
Improvechassis volumeVSAvoidair insulation space
Core Design Contradiction:
Volume of moving objectVSQuantity of substance

Solution Approach 1:

The patent introduces an insulating plate as an intermediary component between copper strips. The insulating plate provides structural support while ensuring electrical insulation, eliminating the need for large air gaps. This mediator allows copper strips to be placed closer together while maintaining safety requirements, thus reducing both chassis volume and air insulation space.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If copper strips or copper bars are used for power transmission, then the distribution board system can be simple in structure, but the power transmission path length increases causing more power loss and heat generation

Engineering Contradiction:
Improvestructure complexityVSAvoidpower loss
Core Design Contradiction:
Device complexityVSLoss of energy

Solution Approach 1:

The patent transitions from three-dimensional copper bar connections to two-dimensional copper strip arrangements on insulating plates. This dimensional change allows for optimized power transmission paths that are shorter and more direct, reducing power loss and heat generation while maintaining structural simplicity through standardized plate configurations.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If copper strips or copper bars are bent or stretched for custom configurations, then the distribution board system can be customized, but the adjustability and expandability deteriorate and installation difficulty increases

Engineering Contradiction:
Improveconfiguration customizabilityVSAvoidinstallation ease
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent divides the power transmission system into modular segments consisting of insulating plates with pre-arranged copper strips. Each plate is a self-contained module that can be independently configured and assembled. This segmentation enables easy customization by selecting different plate configurations and facilitates expansion by simply adding more modules without requiring complex bending or stretching operations.

Inventive Principle:
Principle #1Segmentation

4Adaptability or versatility

If copper strips or copper bars are replaced for extension or adjustment, then the distribution board system can be expanded, but the power transmission path must be powered off causing production loss

Engineering Contradiction:
ImproveexpandabilityVSAvoidproduction continuity
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent implements preliminary action by pre-configuring copper strips on insulating plates during manufacturing. The copper strips are permanently fixed in optimal positions before the system is deployed. This preliminary arrangement eliminates the need for on-site bending, stretching, or replacement operations, allowing expansions and adjustments to be made by simply connecting pre-configured modules without powering off the system, thus maintaining production continuity.

Inventive Principle:
Principle #10Preliminary action
