Pivoting Self-Storing Table for Foldable Chair Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Collapsible chairs lack a practical solution for supporting drinks and larger items, as existing cup holders restrict chair movement and do not provide a stable surface for plates or other items when the chair is folded or unfolded.
Innovation Solution
A self-storing table is pivotally attached to the collapsible chair, allowing it to be in a first position when the chair is closed and a second position when open, supporting items without hindering the chair's movement or storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If cup holders are attached to the frame of the collapsible chair, then drinks can be held, but the chair movement is restricted when attempting to close the chair
Solution Approach 1:
The table is segmented from the chair frame, allowing it to be independently positioned. The table can be in a first position when the chair is closed and a second position when open, enabling the chair to fold freely while still providing table functionality when needed.
Solution Approach 2:
The table is pivotally attached to the chair frame, making it a dynamic component that can change position. This dynamic attachment allows the table to adapt between a stored position during folding and a functional position during use, resolving the conflict between chair mobility and table utility.
2Ease of operation
If a table is attached to the collapsible chair, then plates and items can be supported, but the chair cannot easily open and close
Solution Approach 1:
The pivotable table creates a dynamic system where the table transitions between positions based on chair state. When the chair folds, the table moves to a first position that clears the folding path; when the chair is open, the table can be positioned in a second position to support items, thus achieving both easy folding and item support capability.
Solution Approach 2:
The table nests into a compact configuration when not in use, similar to a nested doll structure. When the chair is closed, the table is positioned within the chair frame structure; when needed, it can be deployed outward to provide support surface, allowing the system to maintain compactness while providing extended functionality.
3Adaptability or versatility
If cup holders are molded into the handle, then cups can be held, but no place is provided for plates or larger items
Solution Approach 1:
The pivotable table provides a universal support surface that can accommodate various items including plates, trays, and larger objects, unlike specialized cup holders. This single multi-functional table replaces the need for multiple specialized holding structures, reducing overall device complexity while increasing versatility.
