Slotted Rectangular Component Kit for Collapsible Frame Structures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing collapsible frame structures, such as cardboard beds, lack homogeneity and stability, often resulting in regions of differing stability and aesthetic issues due to protruding bracket-like regions that can kink and pose tripping hazards.
Innovation Solution
A construction kit comprising flat components of types A and B, subdivided into equally large sections with specific slot arrangements, allowing for the creation of symmetrical, stable, and collapsible frame structures with minimal component types, which can be used to build installations like beds, stools, or platforms without protruding bracket-like ends.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If multiple frame webs are assembled to create a bed surface, then the frame structure can be formed, but the frame webs may slip out of place and the structure lacks homogeneity
Solution Approach 1:
The patent applies homogeneity by using identical rectangular components with standardized slot patterns throughout the entire frame structure. All components have the same dimensions and slot configurations, ensuring uniform stability across the entire bed surface without regions of differing stability. This eliminates the need to assemble different types of frame webs while maintaining structural consistency.
Solution Approach 2:
The patent uses universal rectangular components that can serve multiple positions and functions within the frame structure. The same component type can be used at corners, along edges, or in the center of the frame, reducing the number of specialized parts needed while maintaining assembly stability through consistent slot patterns.
2Reliability
If bracket-like regions protrude perpendicular to the frame web plane, then connection is enabled, but aesthetic appearance deteriorates and tripping hazards are created
Solution Approach 1:
The patent resolves the protruding bracket issue by transitioning the connection mechanism to another dimension. Instead of brackets protruding perpendicular to the frame plane, the connection is achieved through slots cut into the plane of the frame webs, allowing perpendicular insertion of components while maintaining a flat, flush surface that eliminates tripping hazards and improves aesthetics.
Solution Approach 2:
The patent extracts the harmful protruding bracket regions from the design entirely. By using slot-based connections within the plane of the frame webs, the connection function is preserved while the harmful protruding elements are completely removed, eliminating both aesthetic issues and tripping hazards.
3Strength
If hollow sections are used for furnishings production, then structural form is achieved, but collapse capability is lost and connection pieces are required
Solution Approach 1:
The patent applies segmentation by dividing each rectangular component into multiple sections separated by slots. These slots create hinge-like articulation points that allow the frame to collapse while maintaining structural integrity during use. The segmented design enables the frame to flex and collapse without requiring separate connection pieces, as the slots themselves provide the articulation function.
