Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If conventional electromagnetic clutch design is used, then the clutch can achieve basic engagement and disengagement functions, but the overall structure becomes complex and the occupied space increases

Engineering Contradiction:
Improveoverall structureVSAvoidoccupied space
Core Design Contradiction:
Device complexityVSVolume of moving object

Solution Approach 1:

The patent merges the electromagnetic assembly, spring assembly, movable plate, and fixed plate into an integrated clutch unit. The electromagnetic assembly and spring assembly are positioned on opposite sides of the movable plate, with their respective assemblies working together to control engagement. This merging of multiple functional components into a single compact unit reduces overall structural complexity and minimizes occupied space while maintaining the engagement and disengagement functions.

Inventive Principle:
Principle #5Merging (Combining)

2Force

If conventional electromagnetic clutch design is used, then the clutch can provide sufficient electromagnetic force for engagement, but the structure becomes incompact and installation flexibility is reduced

Engineering Contradiction:
Improveelectromagnetic forceVSAvoidinstallation flexibility
Core Design Contradiction:
ForceVSAdaptability or versatility

Solution Approach 1:

The clutch is segmented into distinct functional modules: an electromagnetic assembly with coil and magnetic core, a spring assembly with elastic element, a movable plate, and a fixed plate. Each module can be independently designed and positioned. The electromagnetic assembly and spring assembly are arranged on opposite sides of the movable plate, allowing for flexible spatial configuration that maintains sufficient electromagnetic force while achieving a compact overall structure suitable for various installation positions.

Inventive Principle:
Principle #1Segmentation

3Reliability

If conventional electromagnetic clutch design is used, then the clutch can achieve reliable locking, but the number of components increases and spatial configuration is restricted

Engineering Contradiction:
Improvelocking reliabilityVSAvoidnumber of components
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the essential locking function and implements it through a simplified mechanism: the movable plate with engagement protrusions interacts with the fixed plate with corresponding engagement grooves. The electromagnetic assembly provides the force to press the movable plate against the fixed plate, while the spring assembly provides the separating force. This extraction of the core locking mechanism from complex multi-component systems achieves reliable locking with fewer components and greater design flexibility.

Inventive Principle:
Principle #2Taking out (Extraction)
