Modular Table-on-Wheel Structure for Stable Setup on Uneven Ground
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing table-on-wheel structures lack stability and convenience, failing to stand firmly on various surfaces and being difficult to set up or store, limiting their use and adoption in recreational activities.
Innovation Solution
A combination table design featuring two identical table-on-wheel structures connected by rods, allowing the table to stand firmly on any surface and easily convert into separate units for attachment to car wheels, with extendable foot posts and connection rods for stability and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If existing table-on-wheel structures use simple attachment to car wheels, then the device complexity is reduced, but the stability and reliability of the table deteriorates causing objects to turn over or be damaged
Solution Approach 1:
The table structure is divided into multiple components including desktop frame, stand frame, connection rods, and tail rods that can be assembled and disassembled. This segmentation allows for a more complex but stable structure that can be easily stored when disassembled, resolving the contradiction between stability and device complexity
Solution Approach 2:
The table incorporates adjustable and movable components such as extendable tail rods with joints that can adapt to different wheel sizes and ground conditions. This dynamic design allows the table to maintain stability across various conditions while keeping the structure manageable when not in use
2Ease of manufacture
If existing table-on-wheel structures use simple attachment design, then the ease of manufacture is improved, but the ease of operation deteriorates making setup and storage difficult
Solution Approach 1:
By dividing the table into modular segments (desktop frame, stand frame, connection rods), the design maintains manufacturing simplicity while dramatically improving setup convenience. Each segment can be independently manufactured and then quickly assembled through connection joints, allowing users to easily set up and store the table without complex manufacturing requirements
3Device complexity
If existing table-on-wheel structures are designed for single use with car wheels, then the device complexity is reduced, but the adaptability deteriorates limiting use only when near car
Solution Approach 1:
The table is designed with universal adaptability to serve multiple functions: it can attach to car wheels for mobile use, or be assembled as a standalone combination table for stationary use away from vehicles. The connection rods and stand frame enable the table to function independently on various ground conditions, while still maintaining the option for wheel attachment when needed

AI summary
The present invention discloses combination tables and table-on-wheel structures. Each combination table includes two identical table-on-wheel structures connected side by side with two connection rods and stands firmly on grounds, roads or on object surfaces whether rough or smooth, flat or inclined. Each table-on-wheel structure includes a desktop frame; a stand frame; and two tail rods or connection rods connected together. With the implementation of the present invention, the combination tables or the table-on-wheel structures have the special benefits of being easy to set up or operate; and being able to stand firmly on the ground, no matter it is a level ground, a rough ground or a sloping ground. Each table-on-wheel structure sets firmly upon and applies to all kinds of wheels, whether large or small, and can thus be applied to all kinds of cars. With the foot frames of both the combination tables or the table-on-wheel structures folded at the first joints, convenient storage or transportations are made possible.
