Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If vehicles are adapted to specific roadway lengths, then power distribution can be managed, but the system lacks flexibility for varying roadway lengths and requires manual adjustment

Engineering Contradiction:
Improveadaptability to varying roadway lengthsVSAvoidcomplexity of power distribution management
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The contact means is designed to be movable along the roadway, allowing it to dynamically adjust its position and the length of roadway sections it covers. This dynamic capability enables the system to adapt to varying roadway lengths without requiring manual reconfiguration or fixed vehicle adaptations, resolving the contradiction between adaptability and system complexity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The contact means serves multiple functions: it collects power from conductors, distributes power to different roadway sections, and adapts to various roadway configurations. This multi-functionality allows a single system to handle diverse roadway lengths and power distribution requirements, improving adaptability while managing complexity through integrated design.

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

2Productivity

If continuous energy supply is implemented across elongated road sections, then vehicles can operate without manual adjustment, but power distribution across mutually insulated conductors becomes challenging

Engineering Contradiction:
Improvecontinuous operation capabilityVSAvoidcomplexity of power distribution across insulated conductors
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The roadway is divided into multiple sections with mutually insulated conductors, allowing independent power distribution to each section. The contact means can selectively engage with different conductor sections, enabling continuous energy supply across elongated road sections while managing the complexity of insulation requirements through modular segmentation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system ensures continuous power supply to the vehicle as it moves along the roadway by maintaining constant engagement with the conductor sections. The contact means continuously collects and transfers energy across the insulated conductors, eliminating interruptions and manual adjustments while managing distribution complexity through continuous operational design.

Inventive Principle:
Principle #20Continuity of useful action

3Loss of energy

If a combination of internal and external power sources is used, then efficient power management is achieved, but the system requires coordination between multiple power sources

Engineering Contradiction:
Improveenergy efficiencyVSAvoidcomplexity of power source coordination
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The system combines internal vehicle power sources with external roadway power sources into a unified power distribution system. The contact means facilitates merging these power sources, allowing the vehicle to efficiently utilize external power when available and switch to internal sources when needed, improving energy efficiency while managing coordination complexity through integrated power management.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system dynamically changes power distribution parameters by adjusting the ratio of internal to external power usage based on vehicle needs and roadway conditions. This parameter adjustment enables efficient energy management by optimizing power source selection while the control system manages the complexity of coordinating multiple power sources through adaptive parameter control.

Inventive Principle:
Principle #35Parameter changes
