Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If conventional electromagnetic clutch structure is used, then the clutch can perform switching functions, but the structure becomes complex and occupies larger space

Engineering Contradiction:
Improveclutch structure complexityVSAvoidclutch occupied space
Core Design Contradiction:
Device complexityVSVolume of moving object

Solution Approach 1:

The electromagnetic clutch is divided into modular basic units, each comprising a movable assembly and an electromagnetic assembly. These units can be independently configured and combined, allowing simplified individual structures that collectively achieve the required functionality without excessive complexity or space occupation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The movable iron cores are disposed inside the electromagnetic assembly, with the movable assembly nested within the electromagnetic assembly. This nested configuration allows compact integration of components, reducing the overall occupied space while maintaining functional independence of each subsystem.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Reliability

If conventional electromagnetic clutch design is used, then the clutch can provide locking function, but the overall structure becomes bulky and layout space is limited

Engineering Contradiction:
