Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional headlight devices using multiple light sources face power consumption limitations, making it difficult for small-sized vehicles to mount such devices due to performance constraints on their power systems.
Innovation Solution
A headlight device design that uses a single light source and incorporates a shielding wall between the front lens and reflector, creating the appearance of multiple light sources while minimizing power consumption, with the shielding wall being heat-resistant and gradually increasing in width towards the upper portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple light sources are used in the headlight device, then the illumination intensity and visual appearance are improved, but the power consumption increases
Solution Approach 1:
The reflector is divided into multiple reflection regions (first reflection region and second reflection region) that are spatially separated by a partition wall. This segmentation creates multiple distinct light paths from a single light source, making the headlight appear as if multiple light sources are present while actually using only one bulb, thus maintaining low power consumption while achieving the visual effect and illumination intensity of multiple sources
Solution Approach 2:
A partition wall is introduced as an intermediary structure between the light source and the front lens. This partition wall divides the reflection regions and creates separate light paths, enabling the single light source to produce multiple distinct light beams that illuminate different areas, thereby achieving the effect of multiple light sources without the power consumption of actually using multiple bulbs
2Shape
If multiple light sources are used in the headlight device, then the visual appearance of multiple lamps is achieved, but the device complexity increases
Solution Approach 1:
The reflector is segmented into multiple reflection regions separated by a partition wall, creating distinct light paths that give the visual appearance of multiple separate lamps. This segmentation achieves the desired aesthetic effect while maintaining a single integrated headlight structure, avoiding the complexity of mounting and wiring multiple separate light sources
Solution Approach 2:
The patent combines multiple reflection regions and light paths within a single headlight housing and single light source assembly. By merging these elements into one integrated structure with a partitioned reflector, the design achieves the visual complexity of multiple lamps while simplifying the actual device structure and reducing the number of components needed
3Use of energy by moving object
If a single light source is used instead of multiple light sources, then the power consumption is reduced, but the visual recognition of multiple light sources is lost
Solution Approach 1:
The reflector is divided into multiple reflection regions (first and second reflection regions) separated by a partition wall, creating distinct light paths from a single light source. This segmentation makes the headlight visually recognizable as having multiple light sources while actually using only one bulb, thus maintaining low power consumption while achieving the desired visual appearance
Solution Approach 2:
A partition wall is used as an intermediary structure to divide the reflection regions and create separate light paths within the single headlight assembly. This partition wall enables the single light source to produce multiple distinct light beams that illuminate different areas, creating the visual effect of multiple light sources without the power consumption of actually using multiple bulbs
