Flexible Seat Surface Assembly Without Lateral Guide Mechanisms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seating furniture with resiliently designed seat surfaces formed from shaped bodies is complex, expensive, and difficult to clean due to the need for lateral guidance and high material usage, making it costly and hard to handle.
Innovation Solution
The seating furniture is designed with rigid or dimensionally stable molded bodies connected by an elastically deformable connecting means, allowing for assembly and disassembly without mutual guidance, reducing material costs and simplifying assembly, while maintaining adaptability to user anatomy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If shaped bodies are supported on lateral guide means or adjacent shaped bodies, then the seat surface can be formed with resilient properties, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent removes the complex lateral guide means from the system by allowing shaped bodies to move freely in the longitudinal direction without side guidance. The shaped bodies are only guided in the longitudinal direction, eliminating the need for lateral guidance mechanisms while maintaining resilient seat properties.
Solution Approach 2:
The seat surface is divided into multiple independently movable shaped bodies that can displace individually in the longitudinal direction. This segmentation allows each body to respond independently to load, providing resilient properties without requiring complex inter-body guidance mechanisms.
2Adaptability or versatility
If shaped bodies are positioned individually at close distance on the cushion, then the seat surface can adapt to user anatomy, but the assembly process becomes complicated and time-consuming
Solution Approach 1:
The seat consists of multiple identical shaped bodies that can be manufactured as standard components. These segmented units can be quickly assembled by placing them in sequence on the cushion without individual positioning requirements, significantly reducing assembly time while maintaining anatomical adaptability through the collective arrangement of bodies.
3Stability of the object's composition
If shaped bodies are made elongated for lateral support, then structural stability is improved, but material usage and manufacturing cost increase
Solution Approach 1:
The patent removes the unnecessary longitudinal extension of shaped bodies by eliminating lateral guide means. The shaped bodies only require sufficient width for lateral stability, not extended length for guidance, thereby reducing material consumption while maintaining structural stability through the cushion support and longitudinal movement capability.
4Adaptability or versatility
If shaped bodies stand loosely on the cushion, then the seat can deform under weight, but the shaped bodies may fall out during transport or cleaning
Solution Approach 1:
The shaped bodies are preliminarily positioned and secured on the cushion in a specific arrangement before use. This preliminary positioning ensures they remain in place during transport and cleaning operations, while still allowing the necessary deformation under user load through their ability to displace in the longitudinal direction.
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
This design results in a cost-effective, easy-to-assemble seating solution that adapts to user anatomy without compromising comfort, with reduced material usage and improved handling and cleaning capabilities.
Implementation Method 1
The connecting means is preferably designed as an elastically deformable connecting means. Advantageously, the movability of the shaped bodies in the direction of actuation is retained when the elastically deformable connecting means is provided.
Implementation Method 2
As soon as a person sits down on the seat, the cushion deforms as a result of the weight. Similar to an upholstered piece of furniture, the seat adapts to the anatomy of the user.
