Push Bumper Structure for Dump Trucks Without Light Obstruction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bumper attachments for vehicles do not effectively allow for the transfer of pushing force between two vehicles without obscuring indicator lights or interfering with the wheels of the primary vehicle.
Innovation Solution
A push bumper apparatus with a main portion and a protruding portion coupled to the top side, positioned between indicator lights to avoid obstruction and spaced from the wheels, allowing for safe engagement with a secondary vehicle without damaging it.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the bumper attachment is extended vertically to increase pushing surface area, then the pushing capability is improved, but the indicator lights of the primary vehicle are obscured
Solution Approach 1:
The bumper attachment is divided into a main body portion and a protruding portion. The main body provides the primary pushing surface area, while the protruding portion extends upward to engage with the secondary vehicle's upper structure. This segmentation allows the bumper to achieve sufficient pushing capability without excessively obscuring the indicator lights, as the protruding portion is positioned to clear the light housing while the main body remains below the light level.
2Force
If the engagement surface is positioned closer to the wheels of the primary vehicle, then the pushing force is improved, but the secondary vehicle interferes with the wheels during engagement
Solution Approach 1:
The bumper attachment utilizes vertical positioning (another dimension) to resolve the horizontal conflict between wheel clearance and pushing force. The engagement surface is positioned at a height above the wheel level, allowing the secondary vehicle to push against the bumper without the pushing force being transmitted to the wheels. This dimensional separation maintains effective pushing force while eliminating wheel interference.
3Device complexity
If the bumper attachment structure is simplified, then the device complexity is reduced, but the ability to clear indicator lights and avoid wheel interference is compromised
Solution Approach 1:
The protruding portion is extracted as a separate functional element from the main body of the bumper attachment. This extracted portion specifically addresses the clearance requirement for indicator lights and wheel avoidance, while the main body provides the primary pushing function. This extraction allows the design to meet clearance requirements without overcomplicating the overall structure.

AI summary
A vehicle pushing apparatus for facilitating transferring a pushing force between two vehicles includes a bumper body comprising a main portion and a protruding portion coupled to a top side of the main portion. The bumper body is mountable to a selected one of a front end and a rear end of a primary vehicle such that the protruding portion is positioned between a pair of indicator lights of the primary vehicle. The bumper body may be positioned against a secondary vehicle so that either the primary vehicle may push the secondary vehicle or the secondary vehicle may push the primary vehicle via the bumper body.
