Pickup-Style Work Vehicle Loading Floor Size Changeover Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pickup-style work vehicles face inefficiencies in dumping operations due to the loading floor interfering with the backseat when it is in use, requiring the backseat to be moved out of its use position or raised, which complicates and slows down the dumping process and risks damaging the seat.
Innovation Solution
A pickup-style work vehicle design featuring a loading floor size changeover mechanism that allows the front wall and bottom portions to move rearward, enabling the loading floor to be shifted to a dumping position without relocating the backseat, thus avoiding interference and simplifying the dumping operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the loading floor is moved to a dumping position when the backseat is in the use state, then the dumping operation can be performed, but the loading floor interferes with the backseat causing damage risk and operational complexity
Solution Approach 1:
The loading floor is designed with a size changeover mechanism that allows it to dynamically change its fore-and-aft dimension between a first state (extended forward) and a second state (retracted rearward). This dynamic adjustment enables the loading floor to adapt its configuration based on operational needs, specifically allowing the dumping operation to proceed without interfering with the backseat in its use state.
Solution Approach 2:
The invention changes the physical parameter of the loading floor's fore-and-aft dimension by moving the front wall portion and front bottom portion between forward and rearward positions. This parameter change allows the loading floor to clear the backseat area during dumping operations, eliminating the interference problem while maintaining the backseat in its use state.
2Productivity
If the backseat is moved from its use position to enable loading floor dumping, then the dumping operation can be performed, but the operational process becomes complicated and time-consuming
Solution Approach 1:
The loading floor incorporates a size changeover mechanism that makes it dynamically adjustable in its fore-and-aft dimension. This dynamic capability allows the loading floor to autonomously clear the backseat area during dumping operations without requiring manual intervention to move the backseat, thereby simplifying the operational process while maintaining high dumping speed.
3Productivity
If the loading floor is moved to dumping position with backseat in use state, then dumping efficiency is improved, but the backseat may be damaged due to interference
Solution Approach 1:
The loading floor's size changeover mechanism dynamically adjusts the fore-and-aft dimension of the loading floor between a first state (when backseat is in non-use state) and a second state (when backseat is in use state). This dynamic adjustment ensures that during dumping operations with the backseat in use, the loading floor is configured to clear the backseat area, allowing efficient dumping while preventing damage to the backseat.
Solution Approach 2:
The invention changes the physical parameter of the loading floor's fore-and-aft dimension based on the backseat's state. When the backseat is in the use state, the loading floor's front wall portion and front bottom portion are positioned rearwardly, creating sufficient clearance to prevent interference and damage to the backseat during dumping operations.

AI summary
A pickup-style work vehicle comprises a front driver's seat, a backseat, a loading floor that is located rearwardly of the backseat and that can be moved to a dumping position, a loading floor size changeover mechanism, and a backseat posture change mechanism. The loading floor size changeover mechanism changes the size of the loading floor between a first state in which a front wall portion and a front bottom portion of the loading floor are moved forwardly in a fore-and-aft direction and a second state in which the front wall portion and the front bottom portion of the loading floor are moved rearwardly in a fore-and-aft direction. The backseat posture change mechanism changes a posture of the backseat between a first posture which is a non-use state and a second posture which is a use state. The fore-and-aft dimension of the backseat in the first posture is less than a fore-and-aft dimension of the backseat in the second posture. the backseat in the first posture is located immediately forwardly of the loading floor in the first state and the backseat in the second posture is located immediately forwardly of the loading floor in the second state.
