Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional roadway lighting systems are used, then continuous illumination is provided, but dependency on external power sources increases

Engineering Contradiction:
Improveroad illumination reliabilityVSAvoidexternal power source dependency
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The lighting system generates its own electrical energy through photovoltaic cells that convert sunlight into electricity, and through Peltier modules that convert temperature differentials into electricity. The rechargeable battery stores this self-generated energy for nighttime illumination, making the system self-sufficient and eliminating dependency on external power sources.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system utilizes changes in environmental parameters (sunlight intensity and temperature differentials between day and night) to generate electrical energy. The photovoltaic cells respond to light parameter changes, while Peltier modules respond to temperature parameter changes, converting these natural parameter variations into usable electrical energy for lighting.

Inventive Principle:
Principle #35Parameter changes

2Use of energy by moving object

If solar-powered independent operation is implemented, then external power source dependency is reduced, but device complexity increases

Engineering Contradiction:
Improveindependent power operationVSAvoidlamp circuit structure
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The system merges multiple energy generation methods (photovoltaic cells and Peltier modules) into a single integrated power supply unit. Both energy conversion mechanisms work together to charge a common rechargeable battery, which then powers the lamp circuit, simplifying the overall system architecture while maintaining independent operation capability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The power circuit is designed to perform multiple functions: it receives energy from both photovoltaic cells and Peltier modules, manages battery charging from either source, and provides power to the lamp circuit. This multi-functional design reduces the need for separate systems and reduces overall complexity.

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