Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional knock down table structures rely on fasteners, braces, hinges, and other hardware for stability, which are cumbersome, expensive, and prone to structural failure, lacking simplicity, ease of assembly, and uniform support.
Innovation Solution
The use of tension-stabilized frame support assemblies composed of pre-bent tubes or rods that interconnect through tensioning elements, eliminating hardware and utilizing the balance of tension and compression for self-stabilization, forming spring networks that distribute stress uniformly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional knock down table structures use fasteners, braces, hinges and other hardware for stability, then structural stability is achieved, but device complexity increases and manufacturing cost increases
Solution Approach 1:
The patent removes traditional fasteners, braces, hinges and other hardware components from the table structure. The legs directly insert into sockets with frictional contact providing stability without requiring separate fastening elements. This extraction of unnecessary components reduces device complexity while maintaining structural stability through the frictional mechanism.
Solution Approach 2:
The patent combines multiple functions into integrated components. The legs serve both as structural support and as friction-based fastening elements through their interaction with the sockets and central ring. The tabletop structure integrates both support and stabilization functions, eliminating the need for separate braces and crossbars, thereby reducing overall device complexity.
2Strength
If conventional knock down table structures use multiple hardware components for assembly, then structural support is provided, but ease of manufacture decreases and assembly time increases
Solution Approach 1:
The patent divides the table into simple modular segments: legs with inserted rods, a tabletop with integrated sockets, and a central ring. Each component is manufactured independently with simple geometries, avoiding complex hardware assembly. The segmented design allows for easy manufacturing of individual parts while maintaining overall structural support through their coordinated arrangement.
Solution Approach 2:
The legs are pre-formed with inserted rods that create frictional contact surfaces before final assembly. The tabletop sockets are pre-configured with the central ring positioned to apply outward pressure on the legs. This preliminary preparation of friction surfaces and pressure distribution mechanisms simplifies the final assembly process while ensuring structural support is achieved through the frictional mechanism.
3Stability of the object's composition
If conventional knock down table structures use central rings and struts for stabilization, then structural stability is improved, but loss of substance increases due to more components
Solution Approach 1:
The patent eliminates numerous hardware components including fasteners, braces, hinges, and extraneous support members from the design. Only essential elements remain: legs, inserted rods, sockets, and a minimal central ring structure. This extraction reduces the total material consumption and component count while maintaining structural stability through the friction-based connection mechanism between legs and sockets.

AI summary
Tension-stabilized table structures and frame assemblies to form simplified flat packing furniture that eliminates all fasteners, welds, support hardware and braces. Simplified assembly of pre-tensioned structures providing improved stability, uniformity of support and visual aesthetics. The support systems consist of pre-bent tubes or rods that are linked together to form spring networks that are stabilized and locked together by the balancing of tension and compression. Tabletops or tensioning elements can complete the spring networks to provide tension to the entire assembly, resulting in highly stable tables.
