Solution Overview

Problem

Conventional switchboard assembly methods require significant time and labor to ensure horizontal and vertical busbars are assembled within assembly tolerance, and the lack of positioning members leads to instability in the assembly process.

Innovation Solution

A switchboard assembly facility and method utilizing horizontal busbar reference positioning patch plates, horizontal busbar height positioning plates, and vertical busbar positioning jigs to determine and maintain the precise positions of horizontal and vertical busbars, eliminating the need for extensive adjustments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If positioning members are not used and assembly is performed by direct placement, then the assembly process is simple, but the assembly time and labor increase significantly to achieve tolerance compliance

Engineering Contradiction:

Improveassembly process simplicityVSAvoidassembly speed

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

Positioning members (positioning plates and positioning pins) are pre-installed on the switchboard body before busbar assembly. These positioning members establish reference positions and dimensions in advance, allowing busbars to be directly placed without time-consuming measurement and adjustment during the assembly process.

Inventive Principle:

Principle #10Preliminary action

2Ease of operation

If positioning members are not used and manual adjustment is performed, then the assembly process is flexible, but the assembly quality becomes unstable and dependent on worker skill

Engineering Contradiction:

Improveassembly flexibilityVSAvoidassembly quality consistency

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The positioning members are designed to automatically guide the busbars into the correct positions through mechanical constraints (positioning plates providing reference surfaces and positioning pins providing location constraints). This self-positioning mechanism eliminates dependence on worker skill and ensures consistent assembly quality regardless of who performs the assembly.

Inventive Principle:

Principle #25Self-service

3Manufacturing precision

If measurement tools and manual adjustment are used to achieve assembly tolerance, then the assembly can meet drawing requirements, but the time and labor required increase substantially

Engineering Contradiction:

Improveassembly tolerance complianceVSAvoidassembly time

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

Inventive Principle:

Principle #10Preliminary action

4Device complexity

If no positioning members are present, then the assembly process requires fewer components, but extensive measurement and adjustment work is needed to achieve tolerance

Engineering Contradiction:

Improvenumber of assembly componentsVSAvoidassembly efficiency

Core Design Contradiction:

Device complexityVSProductivity

Solution Approach 1:

Inventive Principle:

Principle #10Preliminary action
