Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If large connectors are used to sustain high power, then the power transmission capability is improved, but the ease of operation deteriorates

Engineering Contradiction:
Improvepower transmission capabilityVSAvoidease of plugging and unplugging
Core Design Contradiction:
PowerVSEase of operation

Solution Approach 1:

The connector is divided into multiple independent contacts (multipole configuration), allowing the connection process to be simplified through rotational symmetry while maintaining high power transmission capability across multiple segmented pathways

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention introduces asymmetric locking mechanisms (spuds, grooves, and springs) that create a specific rotational position for secure connection, making the plugging process intuitive and foolproof while maintaining ease of operation despite large connector size

Inventive Principle:
Principle #4Asymmetry

2Power

If multipole connectors are used to handle high power, then the power transmission capability is improved, but the device complexity increases

Engineering Contradiction:
Improvepower transmission capabilityVSAvoidconnector structure complexity
Core Design Contradiction:
PowerVSDevice complexity

Solution Approach 1:

The rotational symmetry design allows the same basic contact structure to be replicated multiple times around a central axis, creating a multipole connector where each pole performs the same function but collectively handles high power through their combined capacity

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

Solution Approach 2:

Multiple locking mechanisms (spuds, grooves, springs) are combined into an integrated locking system that operates simultaneously across all contacts, simplifying the overall structure by unifying the locking function rather than providing separate locking mechanisms for each contact

Inventive Principle:
Principle #5Merging (Combining)
