Folding Chair Side Table with Rotatable Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional folding chairs lack a built-in mechanism to support objects such as cups, making it inconvenient for users during outdoor activities.
Innovation Solution
A side table integrated with a folding chair, featuring a vertical tube, a bent tube, and a locking mechanism that allows the side table board to be rotated and locked at various angles, providing a stable surface for objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a side table is added to the folding chair, then object support function is improved, but device complexity increases
Solution Approach 1:
The side table is merged with the folding chair structure by integrating the bent tube into the chair frame. The vertical tube is fixed to the chair frame, and the bent tube connects the vertical tube to the side table board, forming an integrated assembly that combines seating and object support functions into a single structure.
Solution Approach 2:
The side table board is designed to be rotatable relative to the bent tube, allowing dynamic adjustment of the table board orientation. The locking mechanism enables the table board to be fixed at different angular positions, providing adaptability for different usage scenarios while maintaining structural integrity.
2Stability of the object's composition
If a locking mechanism is implemented, then stability is improved, but device complexity increases
Solution Approach 1:
The locking mechanism is designed to lock the side table board automatically when rotated to specific angular positions. The mechanism uses the rotation motion itself to engage the locking features, eliminating the need for separate manual locking actions and reducing operational complexity.
3Adaptability or versatility
If the side table board is made rotatable, then adaptability is improved, but reliability decreases
Solution Approach 1:
The side table board is designed to be rotatable relative to the bent tube, allowing dynamic adjustment of the table board orientation. The locking mechanism enables the table board to be fixed at different angular positions, providing adaptability for different usage scenarios while maintaining structural integrity.
Solution Approach 2:
The locking mechanism is designed to prevent unintended rotation or detachment of the side table board during normal use. By providing predetermined locking positions, the mechanism ensures reliable connection while still allowing intentional adjustment when needed.
