Multi-purpose seat
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture lacks versatility in converting between seating and sleeping configurations while maintaining compact storage and space efficiency.
Innovation Solution
A multipurpose seat with a spatial frame comprising fixed legs, longitudinal members, cross members, and folding/sliding boards, equipped with telescopic extensions and movable castors, allowing conversion into a sofa, bed, or additional seating, with optional upholstery or mattress, and compact storage under a coffee table.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the seat is designed with fixed dimensions for single-person seating, then it maintains compact storage space, but it cannot be converted into a bed or sofa for multiple users
Solution Approach 1:
The seat is divided into modular components including a base unit with fixed legs and a separate extendable section with folding legs. This segmentation allows the furniture to be compact when stored as a single-person seat, yet expandable to accommodate multiple users or convert into a bed configuration when needed.
Solution Approach 2:
The folding legs incorporate telescopic extensions that can be dynamically adjusted between retracted and extended positions. This dynamic mechanism enables the seat to transform from a compact single-person configuration to an expanded multi-person or sleeping configuration, resolving the contradiction between compact storage and versatile adaptability.
2Adaptability or versatility
If the seat includes extendable sections with folding legs for multi-person capacity, then it achieves versatile configuration options, but it increases structural complexity
Solution Approach 1:
The telescopic extensions are nested within the folding leg structures, with one component contained within another. This nesting approach consolidates multiple functional elements into a compact integrated system, reducing overall structural complexity while maintaining the ability to provide versatile seating and sleeping configurations.
3Adaptability or versatility
If the seat is designed as a compact single-person unit, then it allows efficient storage under coffee tables, but it lacks the functionality for sleeping or multi-person use
Solution Approach 1:
The folding legs with telescopic extensions provide dynamic transformation capability, allowing the seat to convert between compact storage configuration and expanded functional configurations. The mechanism enables easy transition between states while maintaining compact storage capability when not in use, thus achieving both versatility and storage convenience.

AI summary
The multipurpose seat, as seating furniture with the option of conversion into a daybed or a bed for sleeping, comprising fixed legs (2) interconnected by longitudinal members (1) and cross members (3). At the top, it comprises a folding board (4), beneath which a sliding board (5) is positioned. By extending the sliding board (5) and folding the folding legs (51) from the horizontal into the vertical position, the seat can be adjusted to seat two persons. Another adjustment option is changing the inclination of the folding board (4) from horizontal to inclined, converting the seat into a daybed, or, depending on its dimensions, into a bed for sleeping. The technical solution of the multipurpose seat allows two seats to be joined together by a disassemblable fixed joint and to be converted into a two- or three-seat as well as a bed for sleeping.
