Sliding Pivoting Luggage Board With Underfloor Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional luggage boards in vehicles face issues such as inability to access the space under the board due to rail structures, exposure of rail jaws, risk of luggage falling, and difficulty in supporting loads when used as a bench or table.
Innovation Solution
A luggage space-extensible slidable and pivotable board structure with a board assembly that slides and pivots, incorporating a rail section, handle assembly, and hydraulic actuators to maintain the pivoted state, allowing the board to extend and pivot, and a screen section to prevent luggage from falling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the luggage board is slid along a conventional rail structure, then the board can be extended outward for outdoor activities, but the space under the board becomes inaccessible and the rail jaw is exposed causing appearance deterioration
Solution Approach 1:
The rail structure is divided into two separate rails positioned at the front and rear of the board assembly, allowing independent movement paths. This segmentation enables the board to slide outward while maintaining access to the storage space underneath, as the rails are positioned to clear the under-board area rather than blocking it.
Solution Approach 2:
A cover assembly is introduced as an intermediary component that conceals the rail jaws when the board is in the retracted position. This cover acts as a mediator between the functional rail structure and the aesthetic requirements, hiding the potentially unsightly rail jaws while allowing full sliding functionality.
2Volume of moving object
If the luggage board slides outward for outdoor use, then extended storage and outdoor activity space is obtained, but luggage may fall into the back space from which the board is drawn out
Solution Approach 1:
A screen section is introduced as an intermediary barrier between the extended board space and the rear cargo area. This screen prevents luggage from falling into the back space when the board is extended outward, while still allowing the board to achieve its full extended position for outdoor activities.
Solution Approach 2:
The screen section is designed to be movable, automatically adjusting its position based on whether the board is extended or retracted. When the board extends outward, the screen moves into position to prevent luggage from falling back; when the board is retracted, the screen moves out of the way to maintain access to the cargo area.
3Adaptability or versatility
If the luggage board is used as a bench or table after sliding, then outdoor activity functionality is enhanced, but the load is concentrated at the end of the board making it difficult to support the load
Solution Approach 1:
The support structure transitions from a single-dimensional rail system to a two-dimensional support plane by introducing transverse support members that extend across the width of the board. This dimensional change distributes the load across multiple points rather than concentrating it at the ends, enabling the board to safely support weights when used as a bench or table.
Solution Approach 2:
The support structure is segmented into multiple discrete support members positioned at strategic locations across the board assembly. This segmentation allows the load to be distributed across several support points rather than concentrated at the ends, while maintaining the sliding functionality of the overall board structure.

AI summary
A luggage space-extensible slidable and pivotable board structure is provided. The board structure includes a board assembly configured to slide forward or backward or pivot upward about an inner side thereof in a luggage space of a vehicle, a rail section configured to be coupled to a hinge part at the inner side so as to be pivotable along with the board assembly, and a handle assembly disposed on an outer side of the board assembly to lock the board assembly, wherein the board assembly is unlocked by the operation of the handle assembly to slide along the rail section, and the board assembly is configured to pivot about the hinge part in a locked state.
