Folding chair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing folding chairs require complex disassembly processes for storage, involving detachment of support rods and legs, which is cumbersome and inefficient.
Innovation Solution
A folding chair design with rotatable support rods and legs that can be switched between spread and folded states through rotation, eliminating the need for detachment, and incorporating telescopic rods for further compact storage.

Engineering Contradiction Analysis
1Ease of operation
If the support rod assembly and support leg assembly are unplugged from the mounting frame for storage, then the folding chair can be stored, but the storage process becomes complex and cumbersome
Solution Approach 1:
The patent applies the dynamics principle by enabling the support rod assembly and support leg assembly to rotate dynamically relative to the mounting frame through rotating bases with rotating grooves and shafts. This allows the assemblies to transition between spread and folded states without disconnection, eliminating the complex unplugging process while maintaining storage functionality.
Solution Approach 2:
The patent merges the functions of the support rod assembly and support leg assembly by integrating their mounting mechanisms into a unified rotating base structure. Both assemblies share the same rotating base with coordinated rotating grooves, allowing simultaneous rotation and folding without separate disassembly steps, thus simplifying the storage process.
2Device complexity
If the support rod assembly and support leg assembly remain connected to the mounting frame, then the folding process is simpler, but the storage volume increases
Solution Approach 1:
The rotating base mechanism enables dynamic reconfiguration of the support assemblies during folding. The rotating grooves guide the support rods and legs through controlled rotational paths that maximize compactness in the folded state while maintaining connection to the mounting frame, thus reducing storage volume without requiring disconnection.
Solution Approach 2:
The folding mechanism employs a nested arrangement where the support rod assembly and support leg assembly are rotated to fold back against the mounting frame structure. The assemblies nest within the overall frame geometry when folded, minimizing the external storage volume required while maintaining structural connection.

AI summary
A folding chair includes a cloth cover and a support frame. The support frame includes a horizontally arranged connecting frame and a support assembly mounted on the connecting frame. The support assembly includes two mounting bases arranged at both ends of the connecting frame in an inserted manner, two support rods rotatably mounted on the mounting bases and used for supporting the cloth cover, and two support legs rotatably mounted on the mounting bases. When the folding chair spreads, the two support rods both are obliquely arranged upwards toward a direction away from the length direction of the connecting frame, and there is a first spreading included angle between the two support rods; and the two support legs both are obliquely arranged downwards toward a direction away from the length direction of the connecting frame, and there is a second spreading included angle between the two support legs.
