Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current seating furniture lacks the ability to provide a comfortable and ergonomic experience that supports dynamic, moving sitting, as existing designs do not effectively accommodate resilient and adjustable seating surfaces.
Innovation Solution
A spring component for seating furniture featuring a component body with a base component, support member, lateral spring arms, and hollow chambers, allowing for resilient displacement in three spatial directions, combined with a pivot axis for independent movement of seat components, and manufactured from plastic for cost-effective production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional rigid seating furniture is used, then manufacturing is simple and cost-effective, but the seating surface cannot support dynamic sitting and lacks ergonomic comfort
Solution Approach 1:
The patent applies the dynamics principle by transforming the rigid seating structure into a dynamic system where the support component can pivot and move independently in multiple directions. The lateral spring arms enable the support component to resiliently move relative to the base component, allowing the seating surface to adapt to user movements and provide ergonomic comfort through controlled motion rather than static rigidity.
Solution Approach 2:
The patent segments the seating furniture into distinct functional components: a base component, a support component, and lateral spring arms connecting them. This segmentation allows each component to perform its specific function independently - the base provides stability, the support component creates the seating surface, and the spring arms enable resilient movement - thereby achieving ergonomic complexity through modular design.
2Ease of operation
If resilient and adjustable seating surfaces are implemented, then dynamic sitting is supported, but manufacturing complexity and cost increase
Solution Approach 1:
The patent applies parameter changes by utilizing the elastic properties of plastic material to achieve resilient functionality. The lateral spring arms are designed with specific geometric parameters that allow them to flex and return to their original position, providing dynamic sitting support through material property optimization rather than complex mechanical assemblies, thereby reducing manufacturing complexity.
Solution Approach 2:
The patent employs composite material principles by using plastic material that combines structural rigidity with elastic flexibility. The plastic component is engineered to exhibit both strength for load-bearing and elasticity for resilient movement, eliminating the need for separate metal springs or complex joint mechanisms and simplifying the manufacturing process while maintaining dynamic sitting support capabilities.
3Ease of operation
If multiple independent seat components are mounted on spring components, then ergonomic comfort is enhanced, but device complexity increases
Solution Approach 1:
The patent applies universality by designing the spring component assembly as a multi-functional unit that simultaneously provides structural support, enables dynamic movement, and creates ergonomic seating. The base component and support component work together to fulfill multiple functions - load bearing, motion enabling, and comfort provision - reducing the need for separate specialized components and simplifying the overall assembly.
