Work Vehicle Headlight Protrusion for Lateral Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional work vehicles experience reduced visibility from the front and lateral sides due to inadequate lighting, especially in varying brightness conditions and weather.
Innovation Solution
The work vehicle is designed with head lights arranged on both sides of the hood, featuring protruding front end surfaces and notch portions to allow for improved light reflection, combined with auxiliary light source bodies along the front end surfaces, ensuring light is directed forward and laterally without obstruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the hood blocks the light reflection from head lights, then the head light structure is simple, but the visibility from front and lateral sides is reduced
Solution Approach 1:
The head light assembly protrudes from the hood surface in the vertical dimension, positioning the light source bodies above the hood level. This dimensional change allows light to be emitted and reflected in multiple directions (front and lateral) without being blocked by the hood, thereby improving visibility while maintaining structural simplicity.
Solution Approach 2:
The front end surface of the head light assembly is given a reflective property to redirect light. This localized quality change at the front end surface enables light reflection toward lateral directions, improving lateral visibility without requiring complex additional components throughout the entire head light structure.
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
This configuration enhances visibility from the front and lateral sides by irradiating light in the advancing direction and reflecting it to improve recognition, reducing blind spots and increasing visibility in various conditions.
Implementation Method 1
light is irradiated in the front, left, and right directions of the work vehicle by the reflection of the light from the main light source bodies by means of a reflection means

AI summary
Regarding a tractor in which head lights for illuminating the front by means of a bulb as a main light source body are respectively arranged on both right and left sides of a hood, the front end surface of the head light is formed in such a manner as to protrude to the front as the front end surface advances from an outer side in the right-and-left direction of the hood to the central side in the right-and-left direction of the hood, and the bulb is provided on the outer side in the right-and-left direction of the hood in the head light, and a reflector, which is a reflection means, is provided on the central side in the right-and-left direction of the hood with respect to the bulb of the head light.
