Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the supporting frame is made as one integral unit, then the structural stability is improved, but the ease of carrying and storage deteriorates
Solution Approach 1:
The supporting frame is divided into multiple independent supporting units that can be relatively moved with respect to each other. Each supporting unit can be independently positioned, allowing the frame to be collapsed into a compact configuration for easy storage and transport, while maintaining structural stability when expanded for use.
Solution Approach 2:
The supporting frame incorporates dynamic elements including rotatable bar units, movable inserts, and adjustable brackets that enable the frame to transition between expanded and collapsed states. These dynamic components allow the frame to adapt its configuration based on whether it is being used or stored.
2Ease of operation
If the supporting frame is designed to be disassembled, then the ease of storage is improved, but the device complexity deteriorates
Solution Approach 1:
Multiple supporting units are connected through integrated bar units that combine rotation and support functions. The inserts serve as multi-functional components that simultaneously connect bars to supporting units and provide adjustment capabilities, reducing the need for separate fastening mechanisms and simplifying the overall structure.
Solution Approach 2:
The bar units serve multiple functions: they connect supporting units, enable relative movement between them, and provide structural support. The inserts similarly serve as both connection elements and adjustment mechanisms, eliminating the need for separate components and reducing device complexity.
3Ease of operation
If multiple connection components are added to enable collapsibility, then the ease of operation is improved, but the device complexity deteriorates
Solution Approach 1:
The supporting units are designed to be self-aligning through the bar unit connection mechanism. When the frame is collapsed or expanded, the bars rotate and the supporting units automatically position themselves relative to each other without requiring precise manual alignment, simplifying the operation for the user.
Solution Approach 2:
The bar units are positioned within the structure formed by the supporting units, with inserts nested within the bars. This nested arrangement allows the connection components to be integrated within the overall frame structure rather than adding external complexity, enabling easy operation while maintaining a compact design.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design allows for efficient contraction and expansion of the supporting frames, reducing storage and transportation space requirements while maintaining stability and usability, applicable to various furniture forms like tables and chairs.
Implementation Method 1
The first bar unit has a first end rotatably connected with a first end of the first supporting unit and a second end rotatably connected with a first end of the second supporting unit. The second bar unit has a first end rotatably connected with a second end of the first supporting unit and a second end rotatably connected with a second end of the second supporting unit.

AI summary
Disclosed are a collapsible supporting frame and furniture having a collapsible supporting frame. A frame includes first and second supporting units, and first and second bar units disposed between the first and second supporting units. Each of the first and second supporting units includes a first leg, a second leg, and one or more lateral connecting bars disposed between and fixedly connected with the first and second legs. Each of the first and second bar units includes first and second bars rotatably connected with each other at their proximal ends. A distal end of the first bar is rotatably connected with the first or second leg of the first supporting unit. A distal end of the second bar is rotatably connected with the first or second leg of the second supporting unit.
