Rotatable accessory and folding chair using the same
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture, such as chairs and beds, lack a foldable table top for placing small objects like mobile phones and cups, causing inconvenience and occupying unnecessary space when not in use.
Innovation Solution
A rotatable accessory with a flipping mechanism, including a table top, compression spring, guide column, and rotating shaft, which allows the table top to be folded by rotating around a guide column, enabling convenient storage and space-saving design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a table top is added to the chair or bed for placing objects, then user convenience is improved, but space occupation increases when not in use
Solution Approach 1:
The table top is designed with a flipping mechanism that allows it to rotate between a horizontal position (for placing objects) and a vertical position (for space-saving storage). This dynamic transformation enables the table top to adapt between providing functionality and minimizing space occupation, resolving the contradiction between ease of operation and space efficiency
2Adaptability or versatility
If a table top is added to the chair or bed for placing objects, then functionality is improved, but device complexity increases
Solution Approach 1:
The flipping mechanism is divided into distinct components: a first connecting portion fixed to the table top, a second connecting portion fixed to the chair or bed, a guide column, and a compression spring. This segmentation allows each component to perform a specific function (connection, guidance, force provision) while collectively enabling the overall flipping functionality, making the complex mechanism more manageable and manufacturable
3Area of stationary object
If a flipping mechanism is used to enable folding, then space efficiency is improved, but manufacturing complexity increases
Solution Approach 1:
The compression spring is configured to automatically push the table top from the vertical folded position to the horizontal unfolded position. This self-service mechanism eliminates the need for manual effort or additional actuators to maintain the table top in the ready-to-use position, simplifying the manufacturing process while achieving the desired space-efficient folding capability
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 rotatable accessory provides a functional surface for placing small objects and can be easily folded, reducing space occupation when not in use, enhancing user convenience and space efficiency.
Implementation Method 1
A compression spring is arranged between one side of the first connecting portion and the second connecting portion. Both ends of the compression spring respectively extend into the two first blind holes and abut on the bottom surface of the first blind hole.
Implementation Method 2
The guide column extends into the guide hole and is slidably matched with the guide hole. When the guide column slides out of the guide hole and rotates around the axis of the guide column by an angle A, the guide column can still extend into the guide hole to be slidably matched with the guide hole.

AI summary
A rotatable accessory includes a table top and a flipping mechanism. The flipping mechanism includes a first connecting portion and a second connecting portion. A compression spring is arranged between one side of the first connecting portion and the second connecting portion. The first connecting portion and the second connecting portion are each provided with a first blind hole facing the compression spring. Both ends of the compression spring respectively extend into the two first blind holes and abut on the bottom surface of the first blind hole. The other side of the first connecting portion and the other second connecting portion are connected by a guide hole and a guide column. The rotatable accessory can be mounted on a chair or a bed to allow users to place portable small objects such as mobile phones and cups on the rotatable accessory.
