Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If each driving assembly is connected to a separate wire harness structure, then each stator assembly can be independently powered, but the wiring structure becomes complicated and the system becomes cumbersome

Engineering Contradiction:
Improveindependent power supply reliabilityVSAvoidwiring structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges multiple separate wire harness structures into a single integrated wire harness that connects to multiple driving assemblies through a distribution box. This combining approach reduces the overall wiring complexity while maintaining the ability to independently power each stator assembly, directly resolving the contradiction between reliability and device complexity.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If multiple separate wire harness structures are used for multiple driving assemblies, then each assembly can be independently controlled, but the number of components increases and maintenance becomes more difficult

Engineering Contradiction:
Improveindependent control capabilityVSAvoidmaintenance difficulty
Core Design Contradiction:
Ease of operationVSEase of repair

Solution Approach 1:

The patent segments the wiring system into modular components: a central distribution box and multiple connection terminals that can be independently accessed. This segmentation allows maintenance personnel to work on individual driving assemblies without disturbing the entire wiring system, improving ease of repair while preserving independent control capability through the modular terminal design.

Inventive Principle:
Principle #1Segmentation

3Device complexity

If a single wire harness is used to power multiple driving assemblies, then the wiring structure is simplified and costs are reduced, but the connection structure becomes more complex

Engineering Contradiction:
Improvewiring structure simplicityVSAvoidconnection structure manufacturing complexity
Core Design Contradiction:
Device complexityVSEase of manufacture

Solution Approach 1:

The distribution box is designed as a universal connection structure that can accommodate multiple driving assemblies through standardized connection terminals. This multi-functional design simplifies the overall wiring structure while managing manufacturing complexity through standardization, allowing the same distribution box design to serve multiple applications with different numbers of driving assemblies.

Inventive Principle:
Principle #6Universality (Multi-functionality)
