Foldable Delivery Vehicle Partition Wall With Integrated Table
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing partition walls in delivery vehicles are fixed structures that hinder easy adjustment for varying luggage sizes and are cumbersome to remove or install a removable-type table, limiting their functionality and convenience for drivers.
Innovation Solution
A foldable partition wall with a table function, comprising a fixing frame, first, second, and third folding boards, and a bridge frame, allowing for adjustable partitioning and conversion into a table, facilitated by a withdrawal spring and connection hinges, enabling easy installation and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed partition wall is installed, then the structure is stable and simple, but adjustment for varying luggage sizes is impossible and removal is cumbersome
Solution Approach 1:
The partition wall is designed with multiple folding boards (first, second, and third folding boards) that can be rotated and folded between different positions. The folding boards are connected through rotation shafts and hinges, enabling the partition wall to dynamically adjust its configuration between a installed state (blocking the front passenger seat space) and a removed state (folded against the rear panel), thereby adapting to varying luggage sizes without requiring a complex removable structure.
Solution Approach 2:
The partition wall is divided into multiple independent folding boards (first folding board, second folding board, third folding board) that can be independently rotated and folded. This segmentation allows each board to be positioned flexibly, enabling the partition wall to adapt to different spatial requirements while maintaining structural simplicity through modular components.
2Adaptability or versatility
If a removable-type table is installed, then table functionality is provided, but installation and removal are cumbersome and the table area is narrow
Solution Approach 1:
The partition wall and table are merged into a single integrated structure. The first, second, and third folding boards collectively form both the partition wall when installed and the table surface when folded. This merging eliminates the need for a separate removable table, providing full table functionality while simplifying installation and removal to merely folding and unfolding the existing partition wall structure.
Solution Approach 2:
The folding boards serve multiple functions: they form the partition wall when in the installed position (blocking the front passenger seat space) and form the table surface when folded against the rear panel. This multi-functionality provides both partitioning and table capabilities through a single structure, eliminating the need for separate components and simplifying operation.
3Adaptability or versatility
If the partition wall is made foldable, then adjustment for luggage size is enabled, but the structure becomes more complex
Solution Approach 1:
The partition wall employs a dynamic folding mechanism where the first, second, and third folding boards can be rotated about rotation shafts and folded against the rear panel. This dynamic design enables easy adjustment between installed and removed states while maintaining structural simplicity through the use of standard hinge and rotation shaft components rather than complex actuation systems.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The foldable partition wall allows for flexible loading of luggage of various sizes and provides a convenient table function, enhancing driver usability by eliminating the need for a separate table and simplifying installation/removal processes.
Implementation Method 1
a withdrawal spring with one side connected to the third folding board and the other side connected to a fore-end portion of the bridge frame
Implementation Method 2
The lower plate may have a rotation shaft connected through the first folding board in a state in which the lower plate is placed on an upper surface of the first folding board
Implementation Method 3
a guide pin protruding toward the first folding board at a location spaced apart from the rotation shaft, a guide hole with a radius being a distance from the rotation shaft to the guide pin may be formed in a partial circular shape in the first folding board

AI summary
A partition wall with a table function for a delivery vehicle includes: a fixing frame mounted on a rear panel of a cockpit in a space with a front passenger seat removed; a first folding board rotatably connected to the fixing frame and provided to be folded or unfolded toward the fixing frame; a second folding board disposed on the first folding board in a state in which the first folding board is unfolded, and rotatably connected to the first folding board; and a third folding board rotatably connected to an end portion of the second folding board and provided to be folded or unfolded toward the second folding board.
