Solution Overview
Problem
Current mesh chairs for E-sports, fixed with steel nails on plastic frames, lack sufficient elasticity, leading to discomfort due to inadequate mesh flexibility and restoring force distribution.
Innovation Solution
A spring-type iron frame mesh chair design featuring a reinforcement welded to the chair body, with spring bodies and a connecting ring, an adjusting rod, and a protective frame, allowing for adjustable elasticity through the arrangement of threads and grooves, and a swivel mechanism for user-adjustable comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If mesh is fixed on plastic frame with steel nails by nail gun, then manufacturing is simple and cost-effective, but mesh elasticity is insufficient and user comfort deteriorates
Solution Approach 1:
The patent changes the material parameter of the frame from plastic to iron/steel, and introduces spring bodies to change the elastic parameter of the system. This allows the mesh to have sufficient elasticity while maintaining manufacturing feasibility through welding and standard fastening methods.
Solution Approach 2:
The patent creates a composite structure combining iron frame, spring bodies, and mesh material. This composite design integrates the strength of iron with the elasticity of springs to achieve both structural integrity and comfort requirements.
2Device complexity
If mesh is fixed with steel nails on plastic frame, then device structure is simple, but mesh restoring force is insufficient causing user discomfort
Solution Approach 1:
The patent segments the frame into multiple reinforcements and introduces separate spring bodies for each mesh section. This segmentation allows each spring to provide independent restoring force while maintaining overall structural simplicity through modular assembly.
Solution Approach 2:
The spring bodies act as intermediary elements between the iron frame and the mesh. They mediate the force transmission, providing the necessary restoring force to the mesh while being connected to the rigid frame structure.
3Strength
If spring bodies are added to the iron frame structure, then mesh elasticity is improved, but device complexity increases
Solution Approach 1:
The spring bodies serve multiple functions: they provide elastic support for mesh flexibility, act as shock absorbers, and enable adjustable tension through the adjusting rod mechanism. This multi-functionality justifies the added complexity by delivering multiple benefits from a single component.
Solution Approach 2:
The patent introduces dynamic elements through the spring bodies and adjusting rods, allowing the mesh tension to be dynamically adjusted by users. This transforms the static frame structure into a dynamic system that adapts to user preferences, managing complexity through user-controlled adjustability.
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
Enhances mesh elasticity and user comfort by allowing the spring bodies to absorb pressure and adjust their length, providing flexible support and improved sitting experience.
Implementation Method 1
the spring bodies can pull the reinforcement by their own elasticity. Pressure is applied to the reinforcement and the spring bodies when the mesh body is under pressure

AI summary
The present invention belongs to the technical field of mesh chairs, in particular to a spring-type iron frame mesh chair, wherein it comprises a chair body, and a reinforcement is fixed to the side of the chair body by welding. A mesh body is fixed on the side surface of the reinforcement. Spring bodies are fixed on the inner side of the reinforcement by welding. A connecting ring is connected to one end of the spring bodies different from the reinforcement. An adjusting rod is integrally arranged on the side surface of the chair body. The adjusting rod penetrates the side wall of the chair body. When the mesh chair is in use, the spring bodies can pull the reinforcement by their own elasticity. Pressure is applied to the reinforcement and the spring bodies when the mesh body is under pressure, so that the mesh body becomes flexible and elastic to a certain extent, which improves the user experience. When the adjusting rod is adjusted, the position of the connecting ring is changed simultaneously and the length of the spring bodies varies, then the elasticity of the spring bodies is changed, which makes it easy to adjust the elasticity of the mesh body and improve the user experience.
