Collapsible Stool Nesting Structure for Single-Unit Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing collapsible stools separate into multiple pieces upon folding, making them inconvenient for storage and transportation, unlike the need for a single unit that can be easily stored or transported.
Innovation Solution
A collapsible stool design where the bench body support panel and collapsed bench body member are stored within a non-collapsible bench cap, forming a single unit that maintains the same thickness as the cap's inner height, allowing for easy storage and transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the bench body member and bench cap are made foldable to reduce size, then the stool occupies less space when collapsed, but the components separate into multiple pieces that are inconvenient for storage and transportation
Solution Approach 1:
The collapsed bench body member is inserted into the bench cap, and the bench body support panel is placed within the bench cap, creating a nested configuration where smaller components are stored inside larger ones. This nesting arrangement consolidates multiple separate pieces into a single compact unit that is easy to store and transport while maintaining the space-reducing benefit of the collapsible structure.
2Adaptability or versatility
If the bench body member is made collapsible to reduce footprint, then the stool becomes more portable, but the collapsed components become separate pieces requiring additional storage space
Solution Approach 1:
The design utilizes the bench cap as a container to hold the collapsed bench body member and bench body support panel. By nesting these components within each other and within the cap, the total storage space required is minimized to essentially the volume of the bench cap alone, while maintaining the portability benefits of the collapsible bench body member.
Solution Approach 2:
The invention merges the storage function with the structural function by making the bench cap serve both as the seating cap and as the storage container for the collapsed components. This combination eliminates the need for separate storage bags or containers, reducing the overall storage space requirement while enhancing portability.

AI summary
A collapsible stool for easy storage, comprising a collapsible, bench body member, a bench body support panel; and a bench cap. When in use, the bench cap is mounted on the bench body member in its expanded state. The bench body member, in its expanded state, forms a four-sided cylindrical body. Each of the four walls of the four-sided cylindrical body is made of a soft exterior layer, and a solid composite panel that is enclosed within the soft exterior layer. The bench cap is a non-collapsible cap-shaped body that is formed from a bench cap surface member, and bench cap walls to which the bench cap surface member is connected. The bench cap surface member and the bench cap walls are made of a soft exterior layer, and a solid composite panel enclosed within the soft exterior layer. When stored, the bench body support panel and the collapsed bench body member of the present collapsible stool are disposed in the non-collapsible bench cap, forming a single unit that is convenient for storage and transportation.
