U-Shaped Hood Side Lights for Front-Lateral Work Vehicle Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The configuration of work vehicles with side lights that illuminate the lateral side can make pedestrians feel the vehicle is too bright, causing discomfort.
Innovation Solution
A work vehicle with a hood design featuring U-shaped side lights on the right and left sides, incorporating upper and lower light portions, including a U-shaped upper light portion and a headlight, to illuminate the front-lateral side effectively while avoiding excessive brightness.

Engineering Contradiction Analysis
1Productivity
If work lights are disposed on both the left and right sides of the headlight to illuminate the front-lateral side, then the workability of work at night is improved, but the side of the work vehicle becomes too bright causing discomfort to pedestrians
Solution Approach 1:
The light portion is divided into multiple light sources (headlight and work lights) with different functions and illumination characteristics. The headlight provides primary forward illumination while work lights provide supplemental front-lateral illumination, allowing each light source to be optimized for its specific purpose without over-illuminating areas where it isn't needed.
Solution Approach 2:
Different regions of the front of the vehicle receive different illumination intensities and directions. The headlight focuses illumination forward while work lights illuminate the front-lateral sides, creating localized illumination zones that improve workability without causing excessive brightness in pedestrian areas.
