Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Trampoline frame structures are prone to noise and are cumbersome to assemble, with existing solutions either being complex to manufacture or susceptible to corrosion and breakage, and they do not effectively distribute torsion forces.
Innovation Solution
A trampoline frame structure comprising multiple transverse pipes and joint sleeve structures with elongated headpieces and pyramidical connection extensions that fit into sockets, reducing noise by minimizing twisting and distributing forces evenly, and featuring a design that allows for easy assembly and reduced wobbling.
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 frame structure is divided into modular components (transverse pipes, joint sleeve structures, leg arrangements) that can be independently assembled and disassembled. Each joint sleeve structure serves as a self-contained connection unit with integrated fastening features, allowing rapid assembly without complex multi-step fastening procedures.
Solution Approach 2:
The joint sleeve structure acts as an intermediary component that simplifies the connection between transverse pipes and leg arrangements. It integrates the fastening function into a single structural element rather than requiring separate bolts or screws, thereby reducing assembly steps and time while maintaining disassembly capability.
2Adaptability or versatility
If traditional joint sleeve structures are used with bolts or screws, then the connection can be detached, but the structure produces noise during use due to twisting movements
Solution Approach 1:
The joint sleeve structure is pre-configured with integrated fastening features and geometric constraints that automatically prevent twisting movements upon assembly. The structure is designed beforehand to eliminate relative rotational motion between connected components, thereby preventing noise generation from the outset while maintaining detachability.
Solution Approach 2:
The joint sleeve structure serves as a mediating component that eliminates noise by preventing twisting movements at the connection point. Its integrated design combines connection and stabilization functions, allowing detachable attachment while maintaining rigid alignment and preventing the relative motion that causes noise.
3Stability of the object's composition
If welded frame structures are used, then the frame is rigid and stable, but the welds are susceptible to corrosion and cannot be disassembled
Solution Approach 1:
The frame structure is segmented into separate components (transverse pipes, joint sleeve structures, leg arrangements) connected through mechanical interfaces rather than permanent welds. This segmentation maintains structural rigidity through precision-fit connections while enabling disassembly and reconfiguration, eliminating the corrosion issue associated with welded joints.
Solution Approach 2:
The joint sleeve structure acts as an intermediary connection element that provides rigid, stable coupling between frame components without requiring welds. It achieves frame rigidity through integrated geometric constraints and fastening features while maintaining the ability to detach and reassemble, thereby avoiding the corrosion and permanent attachment problems of welded structures.
4Reliability
If complex joint sleeve structures with conical depressions and threaded bolts are used, then the legs can be securely fixed, but the manufacturing complexity increases and threads are prone to breakage
Solution Approach 1:
The joint sleeve structure merges multiple functions (connection, fastening, alignment, and leg fixation) into a single integrated component. This eliminates the need for separate conical depressions and threaded bolts, reducing manufacturing steps and eliminating thread-related failure modes while maintaining secure leg fixation through unified geometric constraints.
Solution Approach 2:
The joint sleeve structure serves as a mediating component that secures legs through its integrated design, eliminating the need for complex threaded fasteners. It provides reliable leg fixation through unified geometric constraints and fastening features that are simpler to manufacture and less prone to breakage compared to traditional threaded connections.

AI summary
A trampoline frame structure that comprises multiple transverse pipes, joint sleeve structures and leg arrangements is disclosed. The joint sleeve structures serve to connect transverse pipes to form a rim structure. 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.
