Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If mechanical coupling means are used to connect stirrup strap to stirrup bar, then stable attachment is achieved, but engagement operations become cumbersome and difficult to operate

Engineering Contradiction:
Improvestable attachmentVSAvoidengagement operations
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The connection system is divided into separate components: a stirrup bar with coupling means and a stirrup strap with corresponding engagement means. This segmentation allows independent optimization of each component, enabling stable attachment through the coupling mechanism while simplifying engagement operations through the modular design where the strap can be independently positioned and engaged.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces intermediate coupling means as a mediator between the stirrup bar and stirrup strap. This intermediary mechanism facilitates easier engagement by providing a controlled interface that guides the strap into the correct position and secures it firmly, reducing the complexity of direct connection while maintaining stability.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If snap-acting lever is used for automatic release, then release function is provided, but precise adjustment of preloading is difficult

Engineering Contradiction:
Improveautomatic release functionVSAvoidpreloading adjustment
Core Design Contradiction:
ReliabilityVSMeasurement precision

Solution Approach 1:

The patent replaces the traditional snap-acting lever mechanical system with an alternative coupling mechanism that achieves automatic release through force-directed uncoupling. This substitution eliminates the complex preloading adjustment requirements of snap-acting levers while maintaining reliable automatic release functionality when force exceeds a predetermined threshold along the uncoupling direction.

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

3Strength

If mechanical coupling means are used, then secure connection is achieved, but disengagement requires complex mechanisms

Engineering Contradiction:
Improveconnection strengthVSAvoiddisengagement mechanism
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The coupling means are designed with asymmetric characteristics where engagement follows a specific trajectory that is easier to execute, while disengagement requires application of force in a specific uncoupling direction. This asymmetry allows strong connection during normal use while enabling simple automatic disengagement when force exceeds the predetermined threshold, without requiring complex disengagement mechanisms.

Inventive Principle:
Principle #4Asymmetry
