Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple picker types are provided to handle different semiconductor device sizes and tray configurations, then adaptability is improved, but device complexity and operator intervention requirements increase

Engineering Contradiction:

Improveadaptability to different semiconductor device sizes and tray configurationsVSAvoidcomplexity of having multiple picker types and installation requirements

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The picker assembly is designed with a universal structure that can handle different semiconductor device sizes and tray configurations through adjustable components. The driving member can be repositioned along the picker body using the fixing member mechanism, allowing a single picker assembly to perform multiple functions across different device types and tray layouts, eliminating the need for multiple specialized pickers

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The picker assembly incorporates dynamic adjustability through the driving member positioning system. The driving member can be moved to different locations on the picker body and secured at desired positions using the fixing members with latch mechanisms. This dynamic reconfigurability allows the system to adapt to various semiconductor device sizes and tray configurations without requiring multiple fixed picker types

Inventive Principle:

Principle #15Dynamics

2Manufacturing precision

If various kinds of pickers are installed according to semiconductor device types, then picking precision is improved, but ease of operation deteriorates due to installation complexity

Engineering Contradiction:

Improvepicking precision for different semiconductor device typesVSAvoidease of operation reduced by operator installation requirements

Core Design Contradiction:

Manufacturing precisionVSEase of operation

Solution Approach 1:

The fixing member mechanism is designed to enable easy self-adjustment of the driving member position by the operator during operation. The latch member and protruding part design allows for simple engagement and disengagement without requiring complex installation procedures or specialized training. The operator can independently reposition and secure the driving member at different locations on the picker body, making the system self-sufficient and eliminating the need for complex installation protocols

Inventive Principle:

Principle #25Self-service

3Ease of operation

If a detachable picker assembly is implemented for easy reconfiguration, then ease of operation is improved, but reliability may worsen due to attachment and detachment operations

Engineering Contradiction:

Improveease of reconfiguration for different device typesVSAvoidreliability of connection between driving member and picker

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The latch member features a curved engagement surface that works with the protruding part to create a secure mechanical interlock. The curved geometry of the latch member provides a large contact area and progressive engagement, ensuring reliable connection between the driving member and picker body during both attached and detached states. The curved design allows for smooth engagement while maintaining strong mechanical bonding

Inventive Principle:

Principle #14Spheroidality (Curvature)

Solution Approach 2:

The fixing member mechanism combines multiple functions into a single integrated component: positioning, securing, and latching. The fixing member with its latch mechanism merges the attachment and positioning functions, creating a unified solution that ensures reliable connection while maintaining ease of operation. This integration reduces the number of separate components and potential failure points in the detachable connection system

Inventive Principle:

Principle #5Merging (Combining)
