Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If diverse foldable frame structures are used for different furniture, then furniture functionality and variety are improved, but assembly process complexity and training requirements increase
Solution Approach 1:
The patent implements a universal foldable frame structure where the same connection seats and connection rods can be used across different furniture types (chairs, beds, tables). The connection seats are designed with standardized interfaces that accommodate various furniture configurations, allowing one set of components to serve multiple functions and product lines, thereby reducing assembly complexity while maintaining furniture variety.
Solution Approach 2:
The foldable frame is divided into modular components: connection seats, connection rods, and support elements that can be independently assembled and configured. This segmentation allows workers to assemble different furniture types using the same standardized modules, reducing the need to learn entirely new assembly processes for each furniture variety.
2Adaptability or versatility
If diverse foldable frame structures are used for different furniture, then furniture functionality and variety are improved, but worker training time and labor costs increase
Solution Approach 1:
By designing a universal connection system that can be used across all furniture types, the patent eliminates the need for workers to undergo separate training for each furniture variety. The standardized connection seats and rods provide consistent assembly procedures, reducing training time while still enabling production of diverse furniture products.
3Adaptability or versatility
If diverse folding structures are used, then furniture configuration options are improved, but spare part inventory management complexity increases
Solution Approach 1:
The patent employs a universal set of connection seats and connection rods that can be used across all furniture configurations. This standardization dramatically reduces the number of unique spare parts that need to be inventoried and managed, while still providing diverse configuration options through different arrangements and combinations of the same standardized components.
4Adaptability or versatility
If diverse foldable frame structures are used, then furniture design flexibility is improved, but production efficiency and automation potential are reduced
Solution Approach 1:
The patent segments the foldable frame into standardized modular components (connection seats, connection rods) that can be easily assembled and disassembled. This modular approach maintains design flexibility for creating various furniture configurations while enabling standardized assembly processes that can be automated, thereby improving production efficiency.
Solution Approach 2:
By using a universal set of components across all furniture types, the patent creates consistent assembly patterns that can be programmed into automated assembly systems. The standardized interfaces and connection methods enable automation while still allowing for diverse furniture designs through different component arrangements.

AI summary
A foldable frame includes a first connection seat and at least three second connection seats which are arranged at intervals around the first connection seat. The first connection seat and the second connection seats are connected by first connection rods, and the second connection seats are provided with at least one second connection rod. The first connection seat has a first end surface, and the second connection seats each has a second end surface. When the foldable frame is in the extended state and the first end surface faces downward, the second end surface is lower than or is flush with the first end surface, and the free end of the second connection rod is configured to extend upward.
