Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a single light source is used for object detection, then the device structure is simple, but the scanning speed and resolution are insufficient

Engineering Contradiction:

Improvescanning speedVSAvoiddevice structure

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent divides the surveillance environment into multiple lighting sections and uses multiple transmission units (first transmission unit and second transmission unit) to illuminate different sections simultaneously. This segmentation allows parallel scanning of multiple areas, significantly increasing scanning speed while maintaining manageable device complexity through modular architecture.

Inventive Principle:

Principle #1Segmentation

2Measurement precision

If multiple transmission units with different light properties are used, then scanning resolution and coverage improve, but energy consumption increases

Engineering Contradiction:

Core Design Contradiction:

Measurement precisionVSUse of energy by moving object

Solution Approach 1:

Different transmission units emit light with different properties (e.g., different wavelengths or characteristics) tailored to specific lighting sections. This local optimization allows each transmission unit to be tuned for its specific task, improving detection resolution for different object types while managing overall energy consumption by avoiding unnecessary illumination across the entire field.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The transmission units operate in coordinated cycles, illuminating different lighting sections at different times or in alternating patterns. This periodic action allows the system to achieve comprehensive coverage and high resolution through time-multiplexed scanning, reducing peak energy consumption compared to continuous full-field illumination.

Inventive Principle:

Principle #19Periodic action

3Area of stationary object

If the entire surveillance environment is illuminated simultaneously, then detection coverage is comprehensive, but energy consumption and time requirements increase

Engineering Contradiction:

Core Design Contradiction:

Area of stationary objectVSUse of energy by moving object

Solution Approach 1:

The surveillance environment is divided into multiple lighting sections (first lighting section, second lighting section, etc.), each illuminated by dedicated transmission units. This segmentation enables comprehensive coverage through parallel illumination of multiple sections, achieving full-area monitoring without requiring excessive energy from a single omnidirectional source.

Inventive Principle:

Solution Approach 1:

The receiving section is designed to detect reflected light with different light properties (analogous to different colors or wavelengths) that correspond to different transmission units. By analyzing these distinct light properties, the system can accurately identify objects and their characteristics while managing receiving section complexity through specialized detectors tuned to specific light characteristics.
