Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If wire bonding tools are used without suitability determination, then production speed is maintained, but interference and clearance issues occur leading to design flaws

Engineering Contradiction:
Improvetool suitabilityVSAvoiddesign validation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by performing suitability determination of wire bonding tools before the actual wire bonding process. The method includes determining tool specifications, simulating the tool in the wire bonding application, and checking for interference with other structures in advance. This preliminary validation ensures that only suitable tools are selected for production, preventing design flaws and rework while maintaining production speed.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If wire bonding tools are selected without simulation, then development time is reduced, but clearance issues and interference occur during production

Engineering Contradiction:
Improveproduction efficiencyVSAvoidclearance control
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent uses a software simulation tool that creates a virtual copy or model of the wire bonding tool and its interaction with the wire bonding application. This digital replica allows for precise checking of clearance and interference conditions without physical prototyping or trial production. The simulation accurately represents the spatial relationships between the tool and other structures, enabling precise clearance control while maintaining high production efficiency through rapid virtual validation.

Inventive Principle:
Principle #26Copying

3Reliability

If tool suitability is determined through comprehensive simulation, then design quality is improved, but validation time increases

Engineering Contradiction:
Improvedesign validityVSAvoidvalidation process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces complex physical validation processes with a software-based simulation system. Instead of requiring physical prototyping, manual clearance checking, or trial bonding operations, the method uses computational simulation to determine tool suitability. This substitution of mechanical/physical validation with digital simulation reduces the complexity of the validation process while maintaining high design validity and reliability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
