Solution Overview
Problem
Conventional knock down table structures rely on cumbersome hardware, such as fasteners, braces, and hinges, which are expensive to manufacture and prone to structural failure under load, lacking simplicity, stability, and ease of assembly.
Innovation Solution
The use of tension-stabilized frame support assemblies composed of pre-bent tubes or rods that form spring networks, eliminating the need for hardware by balancing tension and compression to provide stability and ease of assembly, with surface elements applying tension to stabilize the structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional hardware (fasteners, braces, hinges) is used to stabilize table structures, then structural stability is achieved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent removes all conventional hardware components (fasteners, braces, hinges, welds) from the table structure, retaining only the essential tubular members. The stabilization function is achieved through the geometric configuration and tension-compression balance of the tubular members themselves, eliminating the need for separate hardware components.
Solution Approach 2:
The tubular members are designed to self-stabilize the structure through their own tension and compression forces. The pre-bent tubular members create inherent geometric stability that eliminates the need for external hardware, allowing the structure to stabilize itself without additional components.

The patent combines the structural support and stabilization functions into a single integrated system of tubular members. The tubular members simultaneously provide structural support, geometric stability, and tension-compression balance, eliminating the need for separate hardware components and reducing manufacturing complexity.
3Strength
If conventional hardware is used in table structures, then structural support is provided, but the hardware becomes primary points of structural failure under load
Solution Approach 1:
The patent removes all conventional hardware components (fasteners, braces, hinges, welds) from the table structure, retaining only the essential tubular members. The stabilization function is achieved through the geometric configuration and tension-compression balance of the tubular members themselves, eliminating the need for separate hardware components.
Solution Approach 2:
The patent changes the structural parameters by using pre-bent tubular members with specific geometric configurations. The tubular members are designed with optimized dimensions, wall thicknesses, and bend radii to distribute loads evenly throughout the structure, eliminating stress concentration points.

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.
