Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional distribution board systems require large spaces for air insulation, leading to increased production costs, power loss, and restricted placement and temperature environments. Additionally, the custom nature of copper strips or bars limits adjustability and expandability, necessitating frequent power shutdowns for maintenance.

Innovation Solution

The distribution board system employs a busway configuration arranged outside the chassis, featuring first and second busways coupled to power supplies and bridged by a switch inside the chassis. This configuration reduces space and material costs, enhances safety by allowing power-on maintenance, and improves heat dissipation and expandability through the use of bridge switches.

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 objectVSArea of stationary object

Solution Approach 1:

The patent extracts the power transmission function from the internal chassis environment and relocates it to an external busway configuration. The busway arrangement outside the chassis eliminates the need for large air insulation spaces within the chassis while maintaining effective power transmission, thus resolving the contradiction between compact chassis volume and required insulation area.

Inventive Principle:

Principle #2Taking out (Extraction)

2Adaptability or versatility

If copper strips or copper bars are bent or stretched to customize power transmission paths, then the distribution board system can be adapted to specific layouts, but adjustability and expandability are poor and installation becomes difficult

Engineering Contradiction:

Improvepower transmission path adaptabilityVSAvoidinstallation ease

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent segments the power transmission system into modular busway sections that can be independently configured and connected. This segmentation allows flexible adaptation to different layouts through standardized connections rather than custom bending, significantly improving both adaptability and installation ease.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The busway configuration enables dynamic adjustment of power transmission paths without requiring physical deformation of conductors. The system can be reconfigured by connecting or disconnecting modular busway sections, providing adaptability while maintaining ease of installation and modification.

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If the distribution board system is expanded or maintained by adjusting copper strips or copper bars, then the configuration can be modified, but the power transmission path must be powered off to ensure operator safety

Engineering Contradiction:

Improveconfiguration adjustabilityVSAvoidoperator safety

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent introduces an external busway configuration as an intermediary between the power source and the distribution board. This external configuration allows maintenance and adjustment operations to be performed on the busway connections outside the chassis environment, enabling configuration changes while maintaining power transmission and ensuring operator safety through isolated work zones.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Area of stationary object

If the power transmission path is extended to accommodate restricted placement space, then the distribution board system can be installed in limited areas, but the increased path length causes more power loss and heat generation

Engineering Contradiction:

Improveplacement spaceVSAvoidpower loss

Core Design Contradiction:

Area of stationary objectVSLoss of energy

Solution Approach 1:

The patent transitions the power transmission path from a three-dimensional routing inside the chassis to a two-dimensional external busway configuration. This dimensional change allows optimized power transmission paths that minimize length and resistance while adapting to restricted placement spaces, thereby reducing power loss and heat generation.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
