Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed camera system is used, then the structure is simple, but it cannot accommodate different license plate dimensions and positioning requirements

Engineering Contradiction:
Improveaccommodation of different license plate dimensionsVSAvoidmodular component positioning system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The camera system is divided into modular components including the camera unit, mounting bracket, and positioning elements that can be independently adjusted. This segmentation allows the system to adapt to different license plate dimensions while maintaining a relatively simple overall structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mounting bracket incorporates adjustable positioning mechanisms that allow dynamic reconfiguration of the camera's location and orientation. This dynamic capability enables compliance with varying local regulations without requiring a completely different fixed structure for each region.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If wireless camera systems with battery are used, then installation is easier, but battery life is limited requiring frequent replacements

Engineering Contradiction:
Improvewireless installationVSAvoidbattery operation duration
Core Design Contradiction:
Ease of operationVSDuration of action of moving object

Solution Approach 1:

The system incorporates an energy harvesting module with solar cells that automatically recharge the battery during operation. This self-service energy replenishment eliminates the need for frequent manual battery replacements while maintaining the ease of wireless installation.

Inventive Principle:
Principle #25Self-service

3Reliability

If wired camera systems are used, then power supply is reliable, but installation complexity increases due to wiring requirements

Engineering Contradiction:
Improvepower supply reliabilityVSAvoidwiring and installation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The energy harvesting module with integrated solar cells provides autonomous power generation, eliminating the need for complex wiring connections while ensuring reliable power supply. The system serves itself by converting solar energy into electrical energy to charge the battery.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The mechanical wiring system is replaced with an energy conversion system using photovoltaic cells. This substitution transitions from a complex electrical connection mechanism to a simpler optical-to-electrical energy conversion process.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Duration of action of moving object

If solar cells are added for energy harvesting, then battery life is extended, but device complexity increases

Engineering Contradiction:
Improvecamera operation durationVSAvoidmodular assembly structure
Core Design Contradiction:
Duration of action of moving objectVSDevice complexity

Solution Approach 1:

The solar cells are implemented as a separate, independently replaceable module within the camera assembly. This segmentation allows the energy harvesting component to be added or removed without affecting the core camera functionality, managing complexity through modular design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mounting bracket structure serves multiple functions: it provides mechanical support, enables positioning adjustment, and houses the energy harvesting module. This multi-functionality reduces the need for additional separate components, managing overall system complexity.

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