Chair Elastic Support Assembly for Higher Load and Durability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional elastic support assemblies for chairs, relying on a single circular elastic cord, lack strength and durability, easily deforming under heavier loads and reducing their lifespan.
Innovation Solution
Incorporating a flat elastic strip and a circular elastic cord between mounting members, secured by locking snaps and binding strings, to enhance strength, stability, and elasticity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If only a single circular elastic cord is used in the elastic support assembly, then the device complexity is reduced, but the strength and load-bearing capacity are insufficient
Solution Approach 1:
The patent combines a flat elastic strip and a circular elastic cord into a single elastic support assembly. The flat elastic strip is threaded through the circular elastic cord to form a composite structure where both elements work together to support the mounting members, thereby increasing the overall strength and load-bearing capacity of the assembly.
2Reliability
If only a single circular elastic cord is used, then the manufacturing is simpler, but the durability and resistance to deformation under heavy loads are reduced
Solution Approach 1:
The flat elastic strip and circular elastic cord are combined in a integrated manner where the strip is threaded through the cord and both are secured to mounting members. This merged structure provides mutual reinforcement, preventing deformation under heavy loads and improving durability while maintaining reasonable manufacturing simplicity through the straightforward assembly process.
3Adaptability or versatility
If a single circular elastic cord is used, then the device structure is simpler, but the elasticity and comfort sensation are reduced
Solution Approach 1:
The combination of the flat elastic strip and circular elastic cord creates a more sophisticated elastic response. The flat strip provides directional elasticity while the circular cord provides omnidirectional elasticity, together offering enhanced adaptability and comfort sensation without excessive structural complexity.
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 combination of a flat elastic strip and circular elastic cord significantly increases the assembly's strength and durability, preventing deformation under long-term use or heavy loads, while providing greater elasticity for user comfort.
Implementation Method 1
an elastic support assembly for a chair, comprising two opposite mounting members, a flat elastic strip mounted between the two mounting members, and a circular elastic cord mounted between the two mounting members

AI summary
An elastic support assembly for a chair includes two opposite mounting members each attached to the chair, a flat elastic strip mounted between the mounting members, and a circular elastic cord mounted between the mounting members. Thus, the flat elastic strip and the circular elastic cord are mounted between the mounting members to reinforce the strength of the elastic support assembly so that the elastic support assembly has a greater strength to withstand a larger load. In addition, the flat elastic strip co-operates with the circular elastic cord to support the mounting members so that the elastic support assembly is not deformed or distorted easily during a long-term utilization or due to a heavier load, thereby greatly enhancing the lifetime of the elastic support assembly.
