VSEngineering Contradiction Analysis

1Adaptability or versatility

If matrix LEDs are used for adaptive driving beams, then light emission control is achieved, but device complexity and component count increase

Engineering Contradiction:
Improveadaptive beam controlVSAvoidcomponent count
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple optical components (scanning module, reflecting units, fluorescent body) into an integrated headlamp assembly with a unified optical path, reducing the overall component count while maintaining adaptive beam control functionality

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The scanning module serves multiple functions: it directs light to different regions, controls beam pattern, and enables adaptive high beam operation, replacing what would traditionally require multiple separate LED modules

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

2Object-affected harmful factors

If traditional lighting systems are used, then simple structure is maintained, but glare control for oncoming vehicles is insufficient

Engineering Contradiction:

Solution Approach 2:

The scanning module dynamically adjusts the light beam direction and intensity in real-time based on detected oncoming vehicles, creating adaptive beam patterns that automatically reduce glare in directions where oncoming traffic is present

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If scanning module with multiple components is implemented, then directional light control is improved, but device size increases

Engineering Contradiction:
Improvedirectional light controlVSAvoidheadlamp assembly size
Core Design Contradiction:
