Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If welding is used to fix the vertical rod to the cross rod, then the assembly is simple, but the assembling strength is insufficient and breakage occurs readily under impact force
Solution Approach 1:
The connection structure is segmented into multiple components: the fitting portion, reinforcing portions, and bearing surfaces. This segmentation allows each component to perform its specific function - the fitting portion provides the base connection, the reinforcing portions strengthen the connection points, and the bearing surfaces distribute loads - thereby achieving both ease of manufacture and high assembling strength
Solution Approach 2:
The connection is enhanced by adding spatial dimensions through the reinforcing portions that extend from the fitting portion to the side surfaces of the branch pipe. This creates a three-dimensional connection structure that distributes stress across multiple surfaces and dimensions, significantly improving assembling strength while maintaining manufacturing simplicity
2Productivity
If traditional manufacturing processes are used, then the production is established, but the manufacturing process is complex and energy consumption is high
Solution Approach 1:
Multiple manufacturing operations are merged into integrated forming processes. The fitting portion, reinforcing portions, and bearing surfaces are formed as integrated structures through advanced forming techniques, eliminating the need for separate manufacturing steps and reducing overall energy consumption while maintaining production efficiency
Solution Approach 2:
The manufacturing process utilizes parameter changes in materials during forming operations to achieve complex geometries without additional processing steps. By controlling material flow and deformation parameters during forming, the intricate connection structure is created in a single operation, reducing energy consumption and simplifying the manufacturing process

AI summary
A trampoline support frame comprises a plurality of transversal branch pipes (1) and a plurality of longitudinal branch pipes (2). The transversal branch pipes (1) are connected to each other to form an annular fiame. Each of the longitudinal branch pipes (2) is provided with a fitting portion (21) and two reinforcing portions (22) integrally extended from the fitting portion (21) to corresponding two side surfaces of the transversal branch pipe (1) and then fixed to the transversal branch pipe (1) by welding, respectively. In this case, the two reinforcing portions (22) of each of the longitudinal branch pipes (2) are extended from and integrally formed with the fitting portion (21), such that each of the transversal branch pipes (1) may be fixed to the two reinforcing portions (22) by welding directly after the transversal branch pipe (1) is placed between the two reinforcing portions (22) without precision alignment, whereby the manufacturing process for the trampoline support frame is simplified, and manufacturing energy consumption is reduced so as to meet requirements for environment protection. Moreover, assembling strength between two opposite outer side surfaces of each of the transversal branch pipes (1) and each of the longitudinal branch pipes (2) is strengthened by means of the two reinforcing portions (22).
