Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If a mechanical chuck mechanism with large holding force is used to automate pin rearrangement, then the automation capability is improved, but the device structure becomes complicated

Engineering Contradiction:

Improveautomation of pin arrangement changing operationVSAvoiddevice structure

Core Design Contradiction:

Extent of automationVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical chuck mechanism with a vacuum suction system. The suction nozzle generates negative pressure to hold the pin module, eliminating the need for complex mechanical chuck mechanisms while achieving automation of pin arrangement changing operations.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent employs a vacuum suction system (pneumatic mechanism) to hold and move the pin module. The suction nozzle creates a pressure difference that securely holds the pin module without requiring complex mechanical gripping structures, thereby simplifying the overall device while enabling automation.

Inventive Principle:
