Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a traditional rigid coupler interface is used to attach implements to power machines, then structural strength and alignment precision are improved, but adaptability to misalignment and ease of operation deteriorate

Engineering Contradiction:

Improvecoupler connection strengthVSAvoidadaptability to misalignment

Core Design Contradiction:

StrengthVSAdaptability or versatility

Solution Approach 1:

The coupler block is made pivotally mountable to the implement carrier frame, allowing it to dynamically adjust its orientation to accommodate misalignment between the power machine and implement couplers while maintaining secure connection

Inventive Principle:
