Foldable Vehicle Luggage Holder with Rigid Base and Hinged Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foldable holding devices in vehicle trunks lack sufficient strength and rigidity, making it difficult to securely hold luggage, and are cumbersome to assemble due to the use of flexible materials and hooks.
Innovation Solution
A foldable holding device with a housing member and raisable top panels that nest within the housing, paired with foldable side panels, forming a container shape with a polygonal periphery, providing increased rigidity and ease of assembly, and allowing for detachable attachment to a floorboard or seat back.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If flexible material is used to form the box-shaped container, then the device is convenient for folding and storage, but the strength is poor when the compartment walls are raised
Solution Approach 1:
The container is divided into compartment walls with rigid lower portions and flexible upper portions. The rigid lower portions provide structural strength when raised, while the flexible upper portions maintain foldability and storage convenience. This segmentation allows the device to simultaneously achieve both strength and ease of operation.
2Reliability
If hooks are used to fasten adjacent compartment walls, then the raised position is maintained, but the assembly becomes bothersome
Solution Approach 1:
The fastening function is merged into the hinge structure itself. The hinge connects adjacent compartment walls and inherently maintains the raised position through its mechanical design, eliminating the need for separate hooks. This integration simplifies assembly while maintaining position reliability.
3Stability of the object's composition
If the lower edge of the side panel is located at the outer side of the line connecting ends of the lower edges of the top panels, then the container shape is stabilized, but the structure becomes more complex
Solution Approach 1:
The lower edge of the side panel is extended outward beyond the line connecting the ends of the top panel lower edges. This dimensional extension creates a stable base that prevents the container from collapsing, while the extension itself serves multiple functions including structural support and positioning, avoiding the need for additional complex components.

AI summary
A foldable holding device provided in a floorboard of a luggage compartment includes: a housing member that is provided at the floorboard; a raisable pair of top panels that nests within the housing member in a housed state, the top panels stand when the top panels are outwardly opened; and a pair of side panels foldably connected to the side edges of each of the top panels, the side panels being configured to outwardly move as the top panels are raised and to form, together with the top panels, a cross section of an open state of the foldable holding device being an inverted trapezoid. Part of a lower edge of one of the side panels is located at an outer side of a line connecting ends of the lower edges of the top panels with respect to the housing member in the plan view in the open state.
