Towing Tractor Hood Inclination for Front View
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The placement of a battery forward of the operator's cockpit in a towing tractor increases the distance from the cockpit to the front end, leading to a narrowing of the front lower view for the operator.
Innovation Solution
The design incorporates a hood with a first inclined surface and a second inclined surface, where the second surface has a greater inclination angle than the first, positioned forward of the first surface, to enhance the front lower view by creating a wider viewing angle without obstructing the view with the battery placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the battery is provided forward of the operator's cockpit, then the arrangement of the drawbar operating lever and linkage is facilitated, but the front lower view from the operator's cockpit is narrowed
Solution Approach 1:
The hood is designed with a two-stage inclined surface structure where the first inclined surface extends from the battery toward the front, and the second inclined surface with a greater inclination angle extends forward from the first inclined surface. This creates a stepped configuration that redirects light and视线 paths, effectively expanding the operator's front lower viewing angle without changing the battery's forward position. The dual-inclination design utilizes spatial dimensionality to resolve the conflict between battery placement and viewing requirements.
2Length of stationary object
If the battery is provided forward of the operator's cockpit, then the distance from the operator's cockpit to the drawbar device is increased, but the distance from the operator's cockpit to the front end is also increased, narrowing the view
Solution Approach 1:
By introducing a hood with varying inclination angles, the patent addresses the viewing angle problem in a different dimensional approach rather than changing the longitudinal distance. The first and second inclined surfaces create multiple reflection and transmission paths for light, effectively expanding the visual field without altering the battery's forward position or the overall vehicle length.

AI summary
A towing tractor includes an operator's cockpit, a battery, a hood, a first inclined surface, a first inclined surface and a second inclined surface. The battery is disposed forward of the operator's cockpit. The hood covers the top of the battery. The first inclined surface is formed on the hood and inclined downwardly toward the front of the towing tractor. The second inclined surface is located forward of the first inclined surface and inclined downwardly toward the front of the towing tractor. The inclination angle of the second inclined surface is greater than the inclination angle of the first inclined surface.
