Foldable Stool With Slotted Height Adjustment for Uneven Ground
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stools lack mobility and adaptability to provide comfort and support on uneven surfaces, limiting their use in various environments.
Innovation Solution
A foldable stool design featuring a base, seat platform with pins, and hingedly attached arms that can occupy different positions, allowing the seat platform to reversibly adjust height and fold for storage, with a slotted portion for pin engagement and a C-shaped configuration for support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the stool is designed with a fixed structure, then it provides stable support, but it lacks mobility and cannot adapt to uneven surfaces
Solution Approach 1:
The patent applies the dynamics principle by making the stool's structure adjustable and movable. The seat platform can be positioned at multiple heights along the arms, and the arms themselves can be adjusted along the base. This dynamic structure allows the stool to adapt to uneven surfaces while maintaining stability through selectable fixed positions.
Solution Approach 2:
The stool is divided into separable components: a base, adjustable arms, and a seat platform with pins. This segmentation allows each component to be independently adjusted and positioned, enabling the structure to conform to uneven surfaces while maintaining overall stability through proper configuration.
2Ease of operation
If the stool is designed as a fixed structure, then it provides support, but it cannot be easily stored or transported
Solution Approach 1:
The adjustable and foldable structure allows the stool to transition between an expanded usable state and a collapsed storage state. The arms can be positioned at different locations along the base, and the seat platform can be at different heights, enabling compact folding for easy storage and transport.
Solution Approach 2:
The stool components are designed to nest within each other when folded. The arms fold along the base, and the seat platform folds along with the arms, creating a compact nested configuration that is easy to store and transport.
3Adaptability or versatility
If the stool provides multiple height positions, then it enhances adaptability, but it increases structural complexity
Solution Approach 1:
The height adjustment mechanism is segmented into discrete positions defined by slots in the arms and pins on the seat platform. This segmentation provides multiple fixed height positions while keeping the mechanism simple, as each pin-slot interaction creates a stable fixed position without requiring complex continuous adjustment mechanisms.
