Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle trunk luggage racks are difficult to fold and quickly detach, limiting their versatility for use as a table during camping activities.
Innovation Solution
A vehicle trunk luggage rack design featuring side frames with horizontal and inclined sections, equipped with wheels and a limiting frame, allowing the storage board to be easily lifted and converted into a table without bearings, and incorporating features like support blocks and elastic members for stability and shock absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If bearings are used in arc-shaped slide rails to enable the storage board to slide, then the storage board can tilt and fold, but the storage board is limited to being either flat or tilted and cannot be quickly detached
Solution Approach 1:
The patent removes the bearings from the slide rail system, extracting the component that was limiting the storage board to fixed positions. This allows the storage board to be freely detached and reattached without being constrained by bearing locations, enabling quick detachment while maintaining folding capability through the arc-shaped guide structure alone
Solution Approach 2:
The support structure is divided into distinct horizontal sections and inclined sections with clear separation points. The storage board can be detached at the transition between these sections, allowing it to serve as a standalone table while the rack maintains its folding functionality through the segmented support structure
2Stability of the object's composition
If the storage board is designed to fold on arc-shaped slide rails, then it can tilt for storage, but additional bearings are required which increase device complexity
Solution Approach 1:
The patent extracts the bearings from the system entirely, reducing device complexity while maintaining folding stability through the geometric design of the arc-shaped guide rails and the interaction between the support plates' horizontal and inclined sections
Solution Approach 2:
The arc-shaped guide rails provide curved guidance for the storage board during folding movements. This curvature enables smooth tilting and folding transitions while eliminating the need for bearings, as the shaped rails themselves guide the motion path
3Strength
If the storage board remains permanently attached to the rack, then structural integrity is maintained, but it cannot be quickly detached for use as a table during camping
Solution Approach 1:
The support structure transitions from a static permanently-attached design to a dynamic system where the storage board can be easily detached and reattached. The horizontal and inclined sections with their geometric interlocking provide structural integrity when assembled, while allowing quick disassembly for table use during camping activities
Solution Approach 2:
The storage board is designed to serve multiple functions: it can be attached to the rack for storage when not needed, or quickly detached to serve as a standalone table during camping activities. The universal design of the support structure accommodates both the rack's storage function and the board's dual purpose as both storage surface and table

AI summary
The present invention discloses a vehicle trunk luggage rack, aiming to flexibly fold the storage board and quickly detach it to serve as a table. Simultaneously, it provides a vehicle with the following technical solution: a vehicle trunk luggage rack comprising a storage board and two side frames arranged at intervals. The side frames are equipped with support plates. The support plates comprise sequentially connected horizontal sections and inclined sections. The inclined sections slope downward away from the horizontal sections. The horizontal sections on the two side frames cooperate to support the storage board when placed horizontally, while the inclined sections on the two side frames cooperate to support the storage board when placed at an angle. This belongs to the technical field of vehicle auxiliary devices.
