Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual separation of gummed paper and lining paper is used, then device complexity is reduced, but productivity decreases and time is lost

Engineering Contradiction:
Improveseparation speedVSAvoidstructure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent employs dynamic rotating structures instead of static manual tools. The first and second rotating structures can rotate relative to each other, with the first rotating structure driving the second through friction contact. This dynamic mechanism automatically separates the gummed paper from the lining paper, transforming manual separation into an automated rotational process that improves productivity while maintaining reasonable device complexity

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The separation mechanism is designed to be self-operating once initiated. The rotating structures create friction that automatically feeds and separates the tape components without requiring continuous manual intervention. The system serves itself by using the rotation of one structure to drive the other, eliminating the need for external power sources or complex control systems

Inventive Principle:
Principle #25Self-service

2Ease of operation

If automated separation mechanism is introduced, then ease of operation improves, but device complexity increases

Engineering Contradiction:
Improveoperation convenienceVSAvoidmechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The device operates on self-service principles where the first rotating structure, when rotated, automatically drives the second rotating structure through friction contact. This self-driving mechanism eliminates the need for motors, sensors, or complex control systems, thereby improving ease of operation while keeping the mechanical complexity relatively simple and maintainable

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The friction contact between the first and second rotating structures acts as an intermediary transmission mechanism. Instead of using complex mechanical linkages or electronic controls, the patent uses friction as a simple yet effective mediator to transfer rotational motion and achieve the separation function, balancing operational ease with mechanical simplicity

Inventive Principle:
Principle #24Intermediary (Mediator)
