Triangular Modular Seat Frame for Fast Assembly and Stacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing modular frames for seats and furnishing elements are difficult to assemble, require specific technical skills, and are not easily stackable or transportable due to their rigid structure and irregular shapes.
Innovation Solution
A modular frame composed of section bars with a triangular cross-section and angled fixing elements that allow for easy assembly and disassembly, enabling the creation of various configurations with a supporting surface, and can be stacked for storage and transport, using common tools and fixing means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If section bars are rigidly fixed together through welding or screws, then structural strength is improved, but assembly complexity and difficulty increase
Solution Approach 1:
The frame is divided into modular section bars that can be independently assembled and disassembled. Each section bar has standardized fixing elements that allow quick connection without welding or complex fastening, reducing assembly complexity while maintaining structural integrity through modular design
Solution Approach 2:
Fixing elements act as intermediaries between section bars, providing a simple connection mechanism that replaces complex welding or screwing processes. These fixing elements enable rapid assembly and disassembly while maintaining the required structural strength
2Stability of the object's composition
If the frame is designed as a complete assembled structure, then structural integrity is improved, but storage and transport efficiency deteriorate
Solution Approach 1:
The complete frame structure is segmented into modular section bars that can be stored in a compact, stacked configuration. When needed, these sections are quickly reassembled into the complete frame structure, allowing efficient storage and transport while maintaining structural integrity through standardized connection mechanisms
Solution Approach 2:
Section bars are designed to nest within each other when stacked for storage, significantly reducing the volume required for storage and transport. The modular design allows sections to be stored in a compact arrangement while enabling rapid reassembly into the full frame structure
3Manufacturing precision
If specialized fixing means are used for assembly, then assembly precision is improved, but ease of operation deteriorates
Solution Approach 1:
The fixing elements are designed to be self-aligning and self-positioning, allowing workers to assemble the frame using common tools without requiring specialized technical skills. The standardized design ensures proper alignment and precision through the fixing elements themselves, eliminating the need for specialized assembly procedures

AI summary
A modular frame for seats or furnishing elements provided with a supporting surface includes a plurality of section bars that are adapted to be rigidly constrained to one another so as to define the frame of the supporting surface. The cross section of the section bars is at least partially hollow and substantially triangular and is provided with an opening configured to allow a conveniently shaped terminal part of fixing elements to be longitudinally inserted in the section bar in order to join at least two section bars.
