Solution Overview

Problem

Conventional substrate conveying hands with separate movable support and pressing units require complex and burdensome positioning, making assembly and maintenance difficult.

Innovation Solution

A substrate holding hand with a common positioner for both the movable support and pressing units, using positioning pins and fixing members to simplify the structure and facilitate easy assembly and maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If separate positioners are used for the movable support unit and movable pressing unit, then each unit can be positioned independently, but the structure of the positioners becomes complex and assembly becomes difficult

Engineering Contradiction:

ImprovePositioning capabilityVSAvoidPositioner structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines the positioners for the movable support unit and movable pressing unit into a single integrated positioner structure. This common positioner simultaneously positions both units, reducing the number of separate positioners from two to one, and simplifying the overall structure while maintaining independent positioning capability for each unit.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The common positioner is designed to perform multiple functions: it positions both the movable support unit and the movable pressing unit. This multi-functional design eliminates the need for separate dedicated positioners for each unit, reducing structural complexity while preserving precise positioning capabilities.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Manufacturing precision

If separate positioners are used for the movable support unit and movable pressing unit, then each unit can be positioned precisely, but assembly time and effort increase

Engineering Contradiction:

ImprovePositioning precisionVSAvoidAssembly time

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

By merging the positioning functions into a single common positioner, the assembly process requires only one positioning operation instead of two separate operations. This reduces assembly time and effort while the positioner maintains precise positioning capability for both the movable support unit and movable pressing unit through its integrated design.

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If the movable support unit and movable pressing unit are separately positioned, then each unit has independent positioning control, but maintenance becomes more difficult

Engineering Contradiction:

ImproveIndependent positioning controlVSAvoidMaintenance difficulty

Core Design Contradiction:

Adaptability or versatilityVSEase of repair

Solution Approach 1:

The common positioner is designed as an integrated structure that can be removed as a single unit. When maintenance is needed, the entire common positioner can be removed together with the movable support unit and movable pressing unit, simplifying maintenance procedures compared to handling multiple separate positioners. The integrated design maintains independent positioning control through its internal configuration.

Inventive Principle:

Principle #5Merging (Combining)
