Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If transverse pipes are connected with joint sleeve structures using bolts or screws, then the frame structure can be disassembled, but the assembly process becomes cumbersome and time-consuming
Solution Approach 1:
The connection extension is inserted into the joint sleeve structure, with the connection extension fitting inside the joint sleeve structure like a nested doll. This nesting arrangement allows for quick insertion and removal without requiring complex fastening operations, thus enabling disassemblability while minimizing assembly time.
Solution Approach 2:
The invention replaces the traditional bolt or screw mechanical fastening system with a friction-based friction fit connection. The connection extension with its specific cross-sectional shape fits into the joint sleeve structure and is held in place by friction forces, eliminating the need for threaded fasteners and significantly reducing assembly time while maintaining disassemblability.
2Ease of operation
If traditional joint sleeve structures are used, then the frame can be assembled, but noise is generated during use
Solution Approach 1:
The invention extracts and eliminates the noise-generating elements from the joint sleeve structure. By removing the need for bolts, screws, or other fastening components that create noise during movement and vibration, the design achieves assembly capability while eliminating the harmful noise factor through the friction fit connection method.
3Strength
If welded frame structures are used, then the frame is strong and stable, but the welds are susceptible to corrosion and cannot be disassembled
Solution Approach 1:
The frame structure is segmented into separate components (joint sleeve structure and connection extension) that can be independently manufactured and assembled. This segmentation allows the frame to maintain strength through proper connection design while enabling disassembly and reassembly, overcoming the limitations of welded structures that are both strong but permanently joined.
4Ease of operation
If complex connection structures are used, then the frame can be assembled, but the structure is cumbersome and difficult to manufacture
Solution Approach 1:
The invention applies local quality by giving the connection extension a specific cross-sectional shape (different from the joint sleeve structure's cross-section) that creates a friction fit connection. This localized geometric feature enables assembly capability while keeping the overall structure simple and easy to manufacture, avoiding the need for complex connection mechanisms.

AI summary
The invention is a trampoline frame structure that comprises multiple transverse pipes (105), joint sleeve structures (106) and leg arrangements (104). The joint sleeve structures serve to connect transverse pipes to form a rim structure (101). Leg arrangements are connected to the joint sleeve structures. At the upper end of the joint sleeve structure is an elongated headpiece, and at both of the ends of the headpiece are sockets. The cross-section of the socket is polygonal. At the ends of the transverse pipes are conical connection extensions, and the cross-sections of the extensions correspond to the cross-sections of the sockets. The assembled rim structure comprises the transverse pipes with the headpieces between them.
