Connecting structure and seat
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seats lack flexibility and functionality, as they are typically single-purpose and require complex tool-based disassembly, limiting their ability to transform between different forms such as cushions, stools, chairs, and armchairs, and do not have a reliable connecting structure for various components.
Innovation Solution
A connecting structure featuring a mounting hole and mounting structure with step and shovel-shaped designs, allowing for quick and easy assembly and disassembly of seat components, including backrests and armrests, using everted protrusions and limiting clamping points for secure interference fits, enabling the seat to be easily converted between different configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional single-function seat designs are used, then manufacturing is simple, but adaptability and versatility are poor
Solution Approach 1:
The seat is divided into independent modular components (cushion, backrest, armrests, supporting legs) that can be separately manufactured and assembled. Each component has standardized connecting structures that enable flexible reconfiguration without increasing individual component complexity
Solution Approach 2:
The connecting structures (mounting hole structure with step structure and limiting clamping points, mounting structure with shovel-shaped structure and everted protrusions) are designed as universal interfaces that can join any two main members, enabling the same components to form multiple seat configurations (cushion, stool, chair, armchair, round-backed armchair)
2Ease of operation
If complex tool-based disassembly methods are used, then connection reliability is high, but ease of operation is poor
Solution Approach 1:
The connecting structures are designed to be self-aligning and self-locking. The step structure guides the shovel-shaped structure into proper alignment, and the everted protrusions automatically engage with the limiting clamping points, enabling tool-free assembly while maintaining reliable connections
Solution Approach 2:
The mounting hole structure and mounting structure act as intermediary connecting elements between main members. These intermediaries provide standardized interfaces that simplify the connection process while ensuring reliable mechanical bonding through the interference fit mechanism
3Adaptability or versatility
If fixed single-form seat structures are used, then structural stability is high, but flexibility and deformability are poor
Solution Approach 1:
The seat transitions from a fixed structure to a dynamic, reconfigurable system. The standardized connecting structures allow components to be easily assembled and disassembled, enabling the seat to adapt its configuration based on different usage scenarios while maintaining structural stability when assembled

AI summary
A connecting structure and a seat. The connection structure comprises a mounting hole structure and a mounting structure correspondingly disposed on two main members to be connected; a step structure extends downwards and inwards on one side of the mounting hole structure, and two sides of the step structure are provided with limiting clamping points protruding in a direction parallel to an extending direction of the step structure; the mounting structure is configured to be a column structure, a bottom end of the column structure is provided with a shovel-shaped structure extending in one side of the column structure, and two sides of the shovel-shaped structure are provided with everted protrusions.
