Sofa with Swivel Feature
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sectional sofas lack the ability to swivel while maintaining a contiguous seating surface and accommodating reclining footrest features, limiting user flexibility and comfort.
Innovation Solution
A sofa design featuring a base portion and a swivel portion that are rotatable between parallel and non-parallel positions, maintaining a contiguous seating surface and incorporating a reclining footrest and reclining mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a sectional sofa is made large and bulky to provide complete seating surfaces and reclining features, then seating comfort and functionality are improved, but the difficulty of moving and repositioning the sofa pieces increases
Solution Approach 1:
The patent applies the dynamics principle by making the sofa sections rotatable about a vertical axis. Each section can be rotated to different angular positions, transforming the sofa from a static configuration to a dynamic one that can be repositioned and reconfigured easily. This rotational capability allows users to change the orientation and arrangement of sofa sections without physically moving them to new locations, thereby improving ease of operation while maintaining seating comfort and functionality.
2Adaptability or versatility
If modular sectional sofa pieces are separated for transportability, then ease of transport is improved, but the complexity of assembly and reconfiguration increases
Solution Approach 1:
The patent applies dynamics by incorporating rotatable joints or mechanisms at the connections between modular sections. These rotational capabilities are built into the modular design, allowing sections to be easily connected and reconfigured through simple rotational movements rather than complex assembly procedures. This reduces the complexity of assembly and reconfiguration while maintaining the transportability benefits of modular design.

AI summary
A repositionable sectional sofa comprises a base portion defining a first seating surface and a first forward direction, and a swivel portion defining a second seating surface and a second forward direction. A forward surface of the swivel portion is movable between a first configuration extending downwardly from a forward edge of the second seating surface and a second configuration extending outwardly from the second seating surface. The swivel portion is rotatable in relation to the base portion between a first position in which the first and second forward directions are parallel and a second position in which the first and second forward directions are non-parallel.
