Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the transportation plates are exposed to the laser beam during workpiece machining, then the laser beam can effectively process the workpiece, but the transportation plates undergo thermal deformation which hinders their movement

Engineering Contradiction:

Improveworkpiece machining efficiencyVSAvoidconveyor movement smoothness

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

A protection component is introduced as an intermediary element between the laser beam and the transportation plate. This protection component selectively blocks the laser beam from reaching the transportation plate while allowing the workpiece to be processed, thereby preventing thermal deformation of the conveyor system and ensuring smooth movement without compromising machining productivity

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If protection components are added to cover the transportation plates, then thermal deformation is prevented, but the device complexity increases

Engineering Contradiction:

Improveconveyor movement smoothnessVSAvoidconveyor system structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The protection component is designed as a thin, flexible structure that can be easily integrated into the existing conveyor system. This minimizes the increase in device complexity while effectively preventing laser beam exposure to the transportation plates, maintaining reliable and smooth conveyor operation
