Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the hexagonal frame is folded through vertical and horizontal movable members, then the trampoline can be folded, but the folding process becomes cumbersome and inefficient
Solution Approach 1:
The frame is divided into multiple telescopic sections with movable connections, allowing each segment to independently adjust its length. This segmentation enables the entire frame to be folded by simply moving the telescopic sections, eliminating the need for complex disassembly and reassembly operations while maintaining structural integrity during folding.
2Stability of the object's composition
If supporting legs are arranged at six corners of the hexagonal frame, then the frame structure is complete, but the span between supporting legs is large and stability is insufficient
Solution Approach 1:
Adjacent supporting legs are merged into a single integrated support structure through the telescopic frame mechanism. The telescopic sections allow the supporting legs to be positioned closer together while maintaining their individual stability functions, effectively reducing the span between them without compromising the overall structural integrity or requiring additional supporting elements.
3Volume of stationary object
If the trampoline is folded, then storage space is reduced, but the jumping mat and connecting members must be disassembled
Solution Approach 1:
The telescopic frame mechanism enables the entire trampoline structure, including the jumping mat and connecting members, to be dynamically folded into a compact configuration. The movable telescopic sections allow the frame to collapse inward while the jumping mat and connecting members remain attached, eliminating the need for separate disassembly operations and achieving compact storage without additional complexity.
