Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing step stools and desks are cumbersome to store, occupy valuable space, and lack flexibility in deployment and stability, especially when used in small or multi-use areas, often leading to unsafe and inefficient use.
Innovation Solution
A lateral folding unit with a vertical frame and pivotally attached linkages that translate laterally to expose multiple receiving surfaces, such as steps, shelves, or desks, featuring integrated handrails and a slim profile for easy deployment and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed step stool or desk is installed, then stability and slip resistance are improved, but space occupation and accessibility flexibility deteriorate
Solution Approach 1:
The step stool transitions from a static fixed structure to a dynamic collapsible structure that can be deployed and stored as needed. The linkage mechanism allows the steps to pivot between a horizontal deployed position providing stable support and a vertical collapsed position minimizing space occupation.
Solution Approach 2:
The step stool is divided into multiple linkages (first linkage, second linkage, third linkage) that can independently pivot and collapse. This segmentation allows each component to fold into a compact configuration while maintaining structural integrity when deployed.
2Area of stationary object
If a collapsible step stool is designed, then storage space is reduced, but ease of operation and stability deteriorate
Solution Approach 1:
The collapsible linkages are designed to nest within each other when collapsed, with the second linkage positioned within the first linkage and the third linkage within the second linkage. This nested configuration minimizes storage space while maintaining a simple operational mechanism.
3Reliability
If a fixed desk is installed, then work surface stability is improved, but adaptability and space efficiency deteriorate
Solution Approach 1:
The desk transitions from a static fixed structure to a dynamic collapsible structure. The linkage mechanism allows the work surface to pivot between a horizontal deployed position providing stable workspace and a vertical collapsed position for compact storage, enabling flexible adaptation to different space requirements.

AI summary
A lateral folding step unit and/or desk unit including a vertical frame and a plurality of linkages pivotally attached at different heights to the vertical frame by one end of each of the linkages, to provide lateral rotation to the linkages. A leg frame, with at least one leg, is pivotally attached to the opposite end of each linkage whereby laterally translating the leg frame simultaneously pivots the linkages from a first, vertical position to at least one second, horizontal position. At least one of the linkages has a receiving surface to serve as a step, a shelf and/or as a work surface.
