Wall mounted collapsible chair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wall-mounted chairs occupy space when not in use and lack efficient storage solutions, especially in areas with limited space such as bathrooms and trains, where they can obstruct movement.
Innovation Solution
A collapsible folding chair design that mounts on a vertical surface, featuring pivotably mounted leg members and a seat element, which can be fully recessed into the frame when closed, along with a backrest that articulates and armrests that automatically retract, allowing for compact storage and easy deployment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wall-mounted chairs are designed to provide seating functionality, then user comfort and accessibility are improved, but space occupation and movement obstruction worsen when not in use
Solution Approach 1:
The chair is designed with dynamic folding mechanisms that allow it to transition between a deployed seating position and a retracted storage position. The seat and backrest can be folded against the wall, transforming the stationary space-occupying object into a dynamic structure that adapts its form factor based on usage needs.
Solution Approach 2:
The chair components are nested within each other when folded, with the seat folding into the backrest structure and both collapsing into a compact form that fits within the wall-mounted frame, minimizing the occupied area when not in use.
2Adaptability or versatility
If conventional wall-mounted chairs are designed, then seating function is provided, but storage efficiency and space retraction worsen
Solution Approach 1:
The chair is divided into segmented components including the seat, backrest, and support structures that can independently fold and collapse. This segmentation allows each component to be compacted efficiently, reducing the overall volume when stored against the wall.
Solution Approach 2:
The chair utilizes the wall surface as a third dimension for storage, collapsing the three-dimensional seating structure into a two-dimensional profile that fits against the wall, effectively using vertical space for storage rather than horizontal floor space.
3Stability of the object's composition
If friction hinges are used to maintain chair position, then stability during use is improved, but deployment complexity and user effort worsen
Solution Approach 1:
The friction hinges are designed to automatically engage and hold the chair in its deployed position without requiring additional locking mechanisms or user intervention. The friction force itself provides the stabilizing action, making the system self-regulating and simplifying the overall deployment mechanism.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design provides convenient, unobtrusive storage by integrating all components into a uniform surface when closed, ensuring minimal space usage and easy deployment with a handle for user activation, while maintaining stability and comfort with friction hinges and leveling elements, reducing the load on wall fasteners and allowing for unencumbered floor cleaning.
Implementation Method 1
Friction hinges may be used to pivotably mount the seat element to the frame
Implementation Method 2
The leg members may be configured with leveling elements
