Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If a diesel generator is installed separately on the trailer to generate power, then power supply capability is improved, but device complexity and maintenance requirements increase

Engineering Contradiction:
Improvepower supply capabilityVSAvoiddevice complexity
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The patent combines the power generation system with the existing brake disc device by integrating a rotor with permanent magnets and a stator with coils into the brake disc assembly. This merging eliminates the need for a separate diesel generator, reducing device complexity while maintaining power supply capability through electromagnetic induction during braking operations.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The brake disc device is transformed into a multi-functional component that simultaneously provides braking functionality and power generation. The rotor and stator are integrated into the brake disc structure, allowing the same mechanical assembly to serve dual purposes: mechanical braking and electrical energy generation, thereby eliminating the need for separate power generation equipment.

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

2Use of energy by moving object

If a diesel generator is installed separately on the trailer to generate power, then power supply capability is improved, but maintenance requirements increase

Engineering Contradiction:
Improvepower supply capabilityVSAvoidmaintenance requirements
Core Design Contradiction:
Use of energy by moving objectVSEase of repair

Solution Approach 1:

The power generation system is merged with the brake disc device, eliminating the need for a separate diesel generator that requires maintenance of fuel injection systems, lubrication systems, and exhaust components. The integrated electromagnetic generator has fewer moving parts and no combustion requirements, significantly reducing maintenance needs.

Inventive Principle:
Principle #5Merging (Combining)

3Device complexity

If power is supplied from the tractor battery, then power supply is simplified, but modifications to the tractor are required

Engineering Contradiction:
Improvepower supply system complexityVSAvoidinstallation complexity
Core Design Contradiction:
Device complexityVSEase of manufacture

Solution Approach 1:

The trailer becomes self-sufficient in power generation through the integrated brake disc system. The rotor with permanent magnets and stator with coils generate electricity directly from the rotational motion during braking, eliminating the need for external power sources from the tractor and the associated wiring modifications.

Inventive Principle:
Principle #25Self-service

4Use of energy by moving object

If a diesel generator is installed separately on the trailer, then power supply capability is improved, but space utilization is reduced

Engineering Contradiction:
Improvepower supply capabilityVSAvoidspace utilization
Core Design Contradiction:
Use of energy by moving objectVSVolume of moving object

Solution Approach 1:

The power generation components (rotor and stator) are integrated into the existing brake disc device structure, utilizing the available space within the brake assembly. This eliminates the need for separate diesel generator installation and reduces the overall space required for power generation functionality.

Inventive Principle:
Principle #5Merging (Combining)
