Tripodal Foldable Mobile Desk Assembly with Integrated Wheels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing desk assemblies lack a tripodal foldable design with wheels that allow locomotion while a user is seated, limiting mobility and functionality.
Innovation Solution
A desk assembly featuring a first leg with wheels, a pivotally engaged rod, and hingedly connected second legs that can be configured for deployment and collapse, enabling locomotion and supporting a panel for article placement, with an actuator system for easy configuration changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a desk assembly is made foldable and mobile with wheels, then mobility and transportability are improved, but structural stability and load-bearing capacity deteriorate
Solution Approach 1:
The desk assembly is divided into three separate legs that can be independently positioned and locked. Each leg is a distinct segment that can be adjusted and secured to provide stable support while maintaining the overall foldable structure for mobility.
Solution Approach 2:
The patent combines the folding mechanism with wheel integration, merging the mobility function into the leg structure itself. The wheels are attached to the legs in a way that allows them to fold together, creating a compact configuration that maintains both mobility and stability.
2Volume of moving object
If a desk assembly is made foldable and collapsible, then storage space and portability are improved, but manufacturing complexity and assembly difficulty worsen
Solution Approach 1:
The desk is segmented into three independent legs connected to a central support structure, allowing each leg to fold independently. This segmentation enables a compact collapsed configuration while using simple, repeatable joint designs that reduce manufacturing complexity.
Solution Approach 2:
The legs are designed to nest together in the collapsed configuration, with each leg containing or adjacent to the others, creating a compact storage form factor. The hierarchical nesting of structural elements simplifies the overall assembly process.

AI summary
A mobile desk assembly for provision of a mobile and transportable workstation includes a first leg, which is positioned between a pair of first plates and engaged thereto by a plurality of first pins so that the first plates bracket the first leg. A seat is engaged to a first end of the pair of first plates. A rod is engaged via a first pivot pin to the first plates, proximate a second end thereof. A pair of second legs is hingedly engaged to the rod distal from the first plates. The first leg, the rod, and the second legs are selectively positionable in a deployed (tripodal) and a collapsed configurations. The first and second legs each have a wheel rotationally engaged thereto. A panel engaged to an upper terminus of the first leg is substantially parallel to the surface and can support an article positioned thereupon.
