Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If supporting legs are pivotally connected to longitudinal bars with additional components (connecting pieces, bolts, nuts), then the bed frame can be folded to minimize size, but the manufacturing complexity and cost increase
Solution Approach 1:
The supporting leg and longitudinal bar are merged into a single integrally formed component. The leg portion and bar portion are connected as one piece through integral forming processes, eliminating the need for separate connecting pieces, bolts, and nuts while maintaining the foldable functionality.
Solution Approach 2:
The integrally formed leg-bar component serves multiple functions: it provides structural support, enables folding motion, and eliminates the need for separate connection components. The single component performs what previously required multiple parts.
2Ease of operation
If supporting legs are pivotally connected with additional components and processes, then the bed frame can be folded, but the manufacturing and installation processes become more difficult and time-consuming
Solution Approach 1:
By combining the leg and bar into one integrally formed component, the manufacturing process is simplified. Instead of requiring pivotal connection processes with multiple components, the invention uses integral forming to create the folded structure directly, reducing manufacturing steps and installation requirements.
3Volume of moving object
If asymmetric arrangement of supporting legs is used, then the folded size is minimized, but the structural symmetry is reduced
Solution Approach 1:
The supporting legs are arranged asymmetrically relative to the longitudinal bar, with legs positioned at different distances from the pivot point. This asymmetric arrangement allows the structure to fold more compactly by optimizing the spatial configuration during folding, accepting reduced symmetry as a trade-off for minimized folded volume.

AI summary
A foldable bed frame includes left and right longitudinal stands. Each of the left and right longitudinal stands includes first and second longitudinal bars pivotally connected to a third longitudinal bar at first and second pivotal points, respectively. Each of the left and right longitudinal stands also includes first, second and third vertical legs fixedly coupled to or integrally formed at the first, second and third longitudinal bars, respectively. The distance between the first vertical leg and the first pivot point is different than the distance between the second vertical leg and the second pivot point such that when folded, one of the first and second vertical legs is disposed in an interior side of the folded left or right longitudinal stand with respect to the other of the first and second vertical legs.
