Reversible Trunk Rack With Rotating Storage Board for Large Cargo
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle trunk racks are nonadjustable in terms of installation height, requiring disassembly and reinstallation for accommodating large objects, which is inconvenient.
Innovation Solution
A reversible vehicle trunk rack with a rotatable connecting piece allowing adjustable installation height, enabling the storage board to be rotated upward for additional space when needed and downward for normal use without disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the trunk rack uses a fixed structure installed at fixed heights, then the installation structure is simple and stable, but the loading space of the vehicle trunk is confined and cannot accommodate large objects
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed rack structure into a movable one. The storage board is connected to the supporting boards via rotatable connecting pieces with locking mechanisms, allowing the rack to dynamically adjust between different height positions. This enables the rack to adapt to different storage needs while maintaining structural stability when locked in position.
Solution Approach 2:
The rack is divided into separable components including the storage board, supporting boards, and connecting pieces. This segmentation allows the storage board to be independently adjusted and repositioned along the supporting boards, providing height adjustability without requiring complete disassembly of the entire rack structure.
2Ease of operation
If the rack is designed to be adjustable in installation height, then the loading space can be flexibly adjusted, but the operation becomes more complex requiring loosening and rotating of components
Solution Approach 1:
The adjustment mechanism utilizes a simple rotatable connecting piece with a locking bolt design. The user can easily rotate the connecting piece to adjust the storage board height and lock it in place, providing intuitive and convenient operation without complex procedures.
Solution Approach 2:
The locking mechanism is designed to be user-operated without requiring external tools or assistance. The locking bolt can be manually inserted and secured by the user themselves, enabling self-service adjustment of the rack height.
3Ease of operation
If the storage board is fixed in position, then the rack structure is simple and stable, but disassembly is required to accommodate large objects which is extremely inconvenient
Solution Approach 1:
The storage board is designed with movable connectivity through rotatable connecting pieces, allowing it to be dynamically repositioned to vertical or inclined positions. This eliminates the need for complete disassembly when accommodating large objects, as users can simply rotate the storage board to create additional space.
Solution Approach 2:
Instead of disassembling the rack to create space, the invention inverts the approach by rotating the storage board upward to an inclined or vertical position, thereby creating space while keeping the rack assembled. This reverse thinking solves the problem of accommodating large objects without disassembly.
4Adaptability or versatility
If the connecting piece allows rotation for height adjustment, then the storage board can be repositioned, but the connecting piece must be securely fixed when rotated to maintain stability
Solution Approach 1:
The connecting piece incorporates both rotational movement capability and a locking mechanism. During adjustment, the connecting piece rotates freely to allow position changes. Once positioned, the locking bolt secures the connecting piece, transforming it from a movable state to a fixed stable state, ensuring rack reliability.
Solution Approach 2:
The connecting piece is designed as a separate component with integrated locking and rotation functions. This segmentation allows independent optimization of both the rotation mechanism for adjustability and the locking mechanism for stability, resolving the contradiction between movement and fixation.

AI summary
This invention is about a reversible vehicle trunk rack, including a first supporting board, a second supporting board, and a storage board. In this utility model, the storage board is fitted with the rotatable connecting piece, so that the installation height of the storage board can be adjusted as required. When large objects need to be put in the trunk, only the supporting arm needs to be loosen and rotated upward, to rotate the storage board to a top of the trunk and lock the supporting arm, so that the trunk has enough storage space. When no large objects need to be put in the trunk, only the supporting arm needs to be loosen and rotated downward, to hang the storage board in the trunk and lock the supporting arm, so that the storage board is in a state of storing objects.
