Vehicle-mounted expandable table system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle-mounted expandable table systems occupy valuable cargo space and experience significant movement and vibration during transit due to their movable nature.
Innovation Solution
A vehicle-mounted table system with a base portion that couples to the vehicle, featuring a table portion with multiple interlocking elements and a compound hinge assembly, allowing for compact storage and reduced vibration by folding into a horizontal configuration during transit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the table system is made movable to facilitate expandability, then adaptability is improved, but stability deteriorates due to significant movement and vibration during vehicle transit
Solution Approach 1:
The table system employs a dynamic design where the table portion can be positioned in multiple configurations (expanded for use, folded for storage). The compound hinge assembly with multiple hinges allows the table elements to pivot and fold dynamically, transitioning between stable expanded and compact folded states while maintaining stability during transit in either position
2Adaptability or versatility
If the table system is designed to be expandable with multiple moving parts, then adaptability is improved, but device complexity increases
Solution Approach 1:
The table system implements a nesting mechanism where the second and third table elements fold beneath the first table element when in the folded configuration. The compound hinge assembly enables this nested arrangement, allowing the table to compact into a space-efficient configuration that reduces its footprint when not in use, effectively hiding the complexity of multiple elements within a compact form
3Adaptability or versatility
If the table portion is made movable for expandability, then adaptability is improved, but volume occupied increases due to space required for movement
Solution Approach 1:
The table system utilizes dynamic folding mechanisms through the compound hinge assembly, allowing the table portion to transition between expanded and folded states. When folded, the table elements pivot to occupy minimal space within the cargo area, dynamically adapting its volume requirement based on whether it is in use or stored
Solution Approach 2:
The table elements are designed to nest within each other when folded, with the second and third elements folding beneath the first element. This nesting arrangement significantly reduces the volume occupied by the movable table system in its stored configuration, minimizing cargo space requirements while maintaining expandability when needed

AI summary
A vehicle-mounted table system includes a table portion that is movable from an expanded configuration to a storage configuration and vice versa. The table portion includes a first table element, a second table element, and a third table element. A first hinge couples the first table element to the second table element, and the first hinge facilitates pivoting motion of the second table element relative to the first table element about a first axis. A compound hinge assembly couples the second table element to the third table element. The compound hinge assembly includes a hinge table element, a second hinge, and a third hinge that facilitate pivoting the second table element relative to the hinge table element about a second axis and the third table element relative to the hinge table element about a third axis. The second and third axes are substantially parallel to the first axis.
