Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual process is used for peeling and grasping the measuring object, then the process is simple to implement, but the measurement accuracy becomes unstable and labor consumption increases

Engineering Contradiction:

Improvepeeling strength measurement accuracyVSAvoidautomation level of peeling and grasping process

Core Design Contradiction:

Measurement precisionVSExtent of automation

Solution Approach 1:

The chucking hand mechanism automatically performs the peeling and grasping operations without requiring manual intervention. The mechanism uses its own components (contact roller, pressurizing mechanism, moving mechanism) to complete the entire process of peeling the measuring object from the substrate and grasping it, thereby eliminating human error and achieving stable, repeatable measurements

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the manual mechanical operation with an automated mechanical system. The chucking hand mechanism, controlled by a control unit, substitutes human hands and operations with a programmed mechanical system that consistently performs peeling and grasping operations with precise control over position, force, and speed

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If manual process is used for peeling and grasping the measuring object, then the device structure remains simple, but the time consumption and labor requirements increase

Engineering Contradiction:

Improvepeeling strength measurement efficiencyVSAvoidcomplexity of peeling and grasping apparatus

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The chucking hand mechanism is divided into functional segments: a contact roller for peeling, a pressurizing mechanism for applying force, and a moving mechanism for positioning. This segmentation allows each component to perform its specific function efficiently while being controlled as an integrated system, improving overall productivity without requiring an overly complex monolithic structure

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The chucking hand mechanism serves multiple functions within a single integrated structure: it positions the measuring object, peels it from the substrate, grasps it, and prepares it for measurement. This multi-functionality increases productivity by consolidating multiple operations into one automated mechanism rather than requiring separate manual steps for each operation

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

First and second operations are executed under control of a peeling inspection control apparatus functioning as a peeling and grasping control unit. In the first operation, a processed surface contact state in which a processed outer peripheral surface of a contact roller and a surface of a lead wire are in contact with each other is maintained, and contact roller rotation operation is executed in which the contact roller is moved on the surface of the lead wire while the contact roller is being rotated. During execution of the first operation, a tip portion of the lead wire is peeled from a glass substrate. Thereafter, in the second operation, grasping operation is executed in which the tip portion of the lead wire peeled from the glass substrate is grasped by a grasping mechanism.
