Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple LED lamps are used for surface illumination, then illumination coverage is improved, but component count and cost increase
Solution Approach 1:
The patent combines multiple illumination functions into a single LED component. The LED is positioned to simultaneously illuminate the upper surface, side surface, and rear surface of the bezel through strategic light reflection paths, eliminating the need for separate LED lamps for each surface while achieving comprehensive surface illumination coverage.
Solution Approach 2:
The patent introduces reflective surfaces as intermediary elements to redirect light from a single LED source to multiple bezel surfaces. The reflection layer and reflective side surface act as mediators that distribute light coverage across upper, side, and rear surfaces without requiring additional light sources.
2Reliability
If multiple components are used in headlight module, then functional performance is improved, but device complexity and size increase
Solution Approach 1:
The patent merges the headlight lamp and bezel into an integrated assembly where the bezel serves dual purposes as both a structural component and an illumination surface. The single LED source replaces multiple separate illumination components, reducing overall device complexity while maintaining functional performance through clever optical design.
Solution Approach 2:
The bezel is designed with multi-functionality, serving as both a structural frame and an illuminated display surface. The reflective side surface of the bezel acts as both a structural element and a light distribution medium, eliminating the need for separate components and reducing overall system complexity.
3Use of energy by moving object
If LED is positioned to illuminate multiple surfaces, then illumination efficiency is improved, but light distribution control becomes difficult
Solution Approach 1:
The patent applies local quality by creating distinct reflective zones on the bezel surface. The reflective side surface is positioned at a specific angle (45 degrees) to redirect light to the rear surface, while the front surface reflects light to the upper surface. Each local area of the bezel is optimized for its specific illumination function, enabling precise light distribution control despite using a single LED source.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design achieves a surface illumination effect with fewer LEDs, improving product quality and design level while reducing costs and component count.
Implementation Method 1
a reflection layer may be formed on the rear surface of the bezel to reflect the light that is radiated from the surface illumination source toward a front side
Implementation Method 2
a light permeable bezel that is disposed in a predetermined area around the lens
Data Source
AI summary
A head light module may include a lamp that radiates light, a lens that directs the light radiated by the lamp to an outside, a light permeable bezel that is disposed in a predetermined area around the lens, and a surface illumination source that radiates light to a side end surface and a rear surface of the bezel. The light radiated by the surface illumination source is directed to a front surface of the bezel.
