Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Force

If the width of the elastic pieces is reduced to lower the pin force, then the pin force is reduced, but the strength of the elastic part is reduced

Engineering Contradiction:
Improvepin forceVSAvoidstrength of the elastic part
Core Design Contradiction:
ForceVSStrength

Solution Approach 1:

The elastic part is divided into multiple divided parts (first divided part, second divided part, third divided part) arranged in the width direction. Each divided part contains multiple elastic pieces, creating a segmented structure that distributes mechanical stress and maintains overall strength while allowing individual pieces to be narrower for reduced pin force.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transitions from a two-dimensional arrangement of elastic pieces to a three-dimensional segmented structure where divided parts are arranged in the width direction and elastic pieces are arranged within each divided part. This multi-dimensional arrangement allows for reduced pin force while maintaining strength through spatial distribution.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If an inclined surface is added to allow additional overdrive, then additional overdrive is possible, but uniform control of compression degree becomes difficult

Engineering Contradiction:
Improveadditional overdrive capabilityVSAvoiduniformity of compression
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The elastic part is segmented into multiple divided parts, each with controlled elastic properties. This segmentation allows the compression force to be distributed uniformly across multiple independent units, ensuring consistent compression degree even with the addition of inclined surfaces for overdrive capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent carefully controls the thickness, width, and material properties of each divided part and elastic piece to standardize the elastic characteristics. By adjusting these parameters, the patent achieves uniform compression across all divided parts while still allowing additional overdrive through the inclined surface mechanism.

Inventive Principle:
Principle #35Parameter changes
