Trampoline Flexible Rod Buckle Assembly and Tension Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional trampolines are difficult to install, have inadequate elasticity adjustment, and are prone to collapse due to low bending stiffness and complex installation structures, making them unsuitable for general use.
Innovation Solution
An easy-to-assemble trampoline design featuring flexible rods with a buckle structure and adjustable installation, using alloy aluminum rods with higher bending stiffness (3000 N/m–10000 N/m) and an elastic member to adjust tension, along with a simplified frame structure and protective net system for improved safety and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the bending stiffness of the flexible rod is increased to improve structural strength and prevent collapse, then the rod becomes harder to install and requires more effort
Solution Approach 1:
The flexible rod is divided into multiple sections that can be assembled in segments. Each section has reduced stiffness individually, making them easier to install, while the combined segmented structure provides the required overall structural strength and stability.
Solution Approach 2:
Connection components or joint mechanisms are introduced between rod sections to facilitate assembly. These intermediaries allow easier installation while maintaining the structural integrity and strength of the complete rod assembly.
2Ease of operation
If the installation structure of the flexible rod is simplified to make installation easier, then the auxiliary role in installation is reduced
Solution Approach 1:
The installation structure is merged with the main rod body or connection points, eliminating separate auxiliary installation components. The rod design incorporates self-aligning or self-locking features that provide installation assistance without adding structural complexity.
3Adaptability or versatility
If the flexible mat elasticity is made fixed to simplify the structure, then it cannot be adjusted to meet different user needs
Solution Approach 1:
The flexible mat system incorporates adjustable tensioning mechanisms or replaceable rod sections that allow users to modify the elasticity and firmness of the mat. This dynamic adjustability enables customization for different user needs without requiring a completely different mat structure.
Solution Approach 2:
The elasticity parameters of the flexible mat can be changed by adjusting the tension of supporting rods or modifying the connection points. This allows the same mat structure to provide different elasticity levels by changing physical parameters such as rod tension or attachment positions.
4Ease of operation
If the flexible rod bending stiffness is reduced to 3000 N/m-10000 N/m to reduce installation effort, then the rod requires deflection of 10-290 mm from natural straightening state
Solution Approach 1:
The flexible rods are pre-deflected or pre-bent during manufacturing to the required installation position, reducing the deflection effort needed during installation. The rods are supplied in a partially prepared state that minimizes the adjustment range required on-site.
