Carrier Box Height Extension With Two-Panel Rear Gate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing utility terrain vehicles (UTVs) with carrier boxes have limited capacity, making it difficult to transport tall objects such as straws and seedlings, and the side panels in some designs allow loaded objects to fall backward.
Innovation Solution
A work vehicle with a carrier box that includes a floor panel, side panels, and a rear gate, where the side panels have an engagement section for a detachable height extension, and the rear gate consists of two panels that can be rotated to provide additional height when a height extension is attached.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the carrier box uses a fixed height design, then the structure is simple, but the capacity cannot be adjusted for different load types
Solution Approach 1:
The rear gate is divided into two separate panels (first panel and second panel) that can be independently positioned. The second panel can be rotated to lie over the first panel when height extension is needed, while the first panel remains in its original position. This segmentation allows the carrier box to accommodate both standard and tall loads without requiring a completely redesigned structure.
Solution Approach 2:
The second panel is designed to be rotatable relative to the first panel, enabling dynamic adjustment of the rear gate height. When tall objects need to be transported, the second panel rotates to provide additional height; when transporting standard loads, the second panel can be positioned flush with the first panel to maintain a compact profile. This dynamic adaptability resolves the contradiction between fixed structure and adjustable capacity.
2Length of moving object
If the side panels are extended to increase height capacity, then tall objects can be transported, but the overall vehicle height increases
Solution Approach 1:
The rear gate height extension is achieved through a segmented two-panel design rather than extending the entire carrier box structure. Only the rear gate area provides height extension when needed, while the side panels maintain their original height. This localized height adjustment allows tall objects to be transported without increasing the overall vehicle height when the extension is not in use.
Solution Approach 2:
The second panel of the rear gate can be rotated to provide height extension only when tall objects need to be transported. When transporting standard-height loads, the second panel lies flush with the first panel, maintaining the vehicle's original height profile. This dynamic height adjustment resolves the contradiction between needing height capacity and maintaining compact vehicle dimensions.
3Length of moving object
If the rear gate is made of a single panel, then the structure is simple, but it cannot provide additional height when needed
Solution Approach 1:
The rear gate is segmented into two panels (first panel connected to the floor panel, and second panel connected to the first panel) that can independently rotate about different axes. This segmentation enables the second panel to extend the height of the rear gate when needed, while the first panel maintains the basic gate structure. The segmented design provides height adjustability without requiring complete structural redesign.
Solution Approach 2:
The two-panel rear gate design allows the second panel to rotate relative to the first panel, dynamically adjusting the rear gate height based on loading requirements. When tall objects are loaded, the second panel rotates to provide additional height; when standard loads are transported, the panels align to maintain a compact structure. This dynamic configuration resolves the contradiction between simple structure and height adaptability.

AI summary
A work vehicle includes: a carrier box including: a floor panel; a pair of left and right side panels; and a rear gate supported by the floor panel in such a manner as to be capable of being opened and closed, the side panels being provided with an engagement section to which a height extension is detachably attachable, the rear gate including: a first panel connected with the floor panel in such a manner as to be movable rotationally; and a second panel connected with the first panel in such a manner as to be movable rotationally, wherein attaching the height extension to the engagement section and positioning the second panel over the first panel provides an additional height for both of the side panels and the rear gate.
