Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If the electrical power collector is continuously activated to collect power from the track line, then the power collection capability is improved, but the wear on the sliding contact increases

Engineering Contradiction:
Improvepower collection capabilityVSAvoidsliding contact lifespan
Core Design Contradiction:
Use of energy by moving objectVSReliability

Solution Approach 1:

The electrical power collector is dynamically activated and deactivated based on real-time detection of light indicators on the track line. The system transitions from a static continuous operation mode to a dynamic on-demand mode, where the sliding contact engages with the track line only when active power segments are detected ahead, thereby reducing unnecessary wear while maintaining power collection capability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system uses a camera to detect light indicators on the track line and provides feedback to the control circuit, which then activates or deactivates the electrical power collector accordingly. This closed-loop feedback mechanism ensures the sliding contact operates only when needed, optimizing both power collection and component lifespan.

Inventive Principle:
Principle #23Feedback

2Reliability

If the sliding contact is kept in contact with the track line to ensure power availability, then the power supply reliability is improved, but the wear and energy loss increase

Engineering Contradiction:
Improvepower supply reliabilityVSAvoidenergy loss from continuous contact
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

Instead of continuous contact, the sliding contact operates in periodic intervals based on the detection of active light indicators on the track line. The system periodically engages the power collector when power segments are detected and disengages when they are not, reducing energy loss from friction and heat while maintaining reliable power supply when needed.

Inventive Principle:
Principle #19Periodic action

3Device complexity

If manual operation of the electrical power collector is used, then the system complexity is reduced, but the efficiency and wear control deteriorate

Engineering Contradiction:
Improvecontrol system complexityVSAvoidpower collection efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The system performs self-service by automatically detecting light indicators on the track line and controlling the activation of the electrical power collector without manual intervention. The camera-based detection system and control circuit work autonomously to optimize power collection efficiency and minimize wear, eliminating the need for complex manual operation while maintaining simplicity in the overall system architecture.

Inventive Principle:
Principle #25Self-service
