Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If multiple straight or curved tubes are welded connected or connected by connectors, then the trampoline frame structure is stable, but the installation is difficult and requires professionals
Solution Approach 1:
The frame is divided into multiple independent tube sections with standardized connection interfaces. Each section can be separately manufactured and transported, then assembled by end users through simple insertion and fixation operations, eliminating the need for professional installation while maintaining structural stability.
Solution Approach 2:
A specialized connector component is introduced as an intermediary between frame tube sections. This connector includes a insertion hole that receives a fixation component, providing a standardized and user-friendly connection mechanism that simplifies assembly while ensuring stable frame structure.
2Ease of manufacture
If the frame size is fixed, then the manufacturing is simple, but it can't meet the requirements of different users
Solution Approach 1:
The frame design allows dynamic reconfiguration by enabling users to add or remove tube sections and adjust the arrangement of flexible rods. The standardized connectors and hole patterns permit the frame to adapt to different size requirements while maintaining manufacturing simplicity through modular construction.
Solution Approach 2:
The frame tubes and connectors are designed with universal interfaces that can accommodate different configurations and sizes. The same standardized components can be used to create various frame sizes and shapes, making the manufacturing process simple while providing versatility for different user needs.
3Ease of manufacture
If flexible rods are installed on traditional frame connectors, then the assembly is possible, but the distribution is uneven which affects the elasticity of bouncing pad
Solution Approach 1:
The frame tube sections are pre-equipped with multiple holes at predetermined positions during manufacturing. This preliminary arrangement of holes ensures that flexible rods can be uniformly distributed when assembled, as the hole positions are pre-planned to achieve even spacing and optimal elasticity distribution across the bouncing pad.
4Ease of operation
If adjacent tubes are connected without prevention of rotation, then the assembly is simple, but harsh friction noise is generated during player jumping
Solution Approach 1:
The connector serves as an intermediary component that includes a fixation mechanism (such as a screw or clip) to prevent relative rotation between adjacent tubes. This simple addition eliminates harsh friction noise during use while maintaining assembly simplicity, as the rotation prevention feature is integrated into the standard connector design.

AI summary
A trampoline frame formed by multiple frame pipes connected in turns, the adjacent two frame pipes are connected by a frame connector, which is a T-shaped pipe composed of a horizontal pipe and a vertical pipe; the outer diameter of the horizontal pipe is smaller than the inner diameter of the frame pipe; two ends of the horizontal pipe are inserted into the adjacent two frame pipes respectively so as to form a closed trampoline frame; the top surface and the bottom surface of the frame pipe are provided with plurality of equally spaced upper frame holes and plurality of equally spaced lower frame holes respectively, and the upper frame holes and the lower frame holes are staggered in pairs; the top surface and the bottom surface of the horizontal pipe are provided with plurality of equally spaced upper insert holes and plurality of equally spaced lower insert holes respectively, the upper insert holes and the lower insert holes are staggered in pairs; when the two ends of the horizontal pipe are inserted into the adjacent two frame pipes, each of the upper insert holes coincides with the corresponded the upper frame hole respectively, and each of the lower insert holes coincides with the corresponded the lower frame hole respectively. The structure of the trampoline frame in the present application is simple with improved stability, which makes the assembly and disassembly easy and convenient.
