Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a communication device is integrated into the generator, then data transmission capability is improved, but device complexity increases

Engineering Contradiction:
Improvedata transmission capabilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The communication device is integrated into the stator carrier of the generator, merging two separate functions (power generation and data transmission) into a single unified structure. This eliminates the need for separate mounting brackets, additional wiring harnesses, and independent power supply circuits, thereby reducing overall system complexity while enhancing data transmission capability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The stator carrier is designed to serve dual purposes: it acts as both the structural support for the generator coils and as the mounting platform for the communication device. This multi-functional design allows the generator to simultaneously generate electrical power and transmit operational data, improving versatility without proportionally increasing complexity.

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

2Use of energy by moving object

If the communication device is integrated on the stator carrier, then energy supply efficiency is improved, but manufacturing complexity increases

Engineering Contradiction:
Improveenergy supply efficiencyVSAvoidmanufacturing complexity
Core Design Contradiction:
Use of energy by moving objectVSEase of manufacture

Solution Approach 1:

The communication device shares the same power supply circuitry as the generator load, merging the energy supply paths. This eliminates the need for separate batteries, voltage regulators, and power management circuits for the communication device, thereby improving energy supply efficiency while keeping manufacturing processes relatively simple through standardized electrical connections.

Inventive Principle:
Principle #5Merging (Combining)

3Area of stationary object

If poles are removed from the stator carrier, then space for communication device is improved, but generator performance deteriorates

Engineering Contradiction:
Improvespace for communication deviceVSAvoidgenerator performance
Core Design Contradiction:
Area of stationary objectVSPower

Solution Approach 1:

Instead of uniformly reducing the number of poles across the entire stator, the design removes poles only in specific localized areas where the communication device needs to be mounted. The remaining poles continue to generate sufficient magnetic flux to maintain generator performance, while the removed pole regions provide necessary mounting space. This selective approach preserves overall power generation capability while creating local space for integration.

Inventive Principle:
Principle #3Local quality
