Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trampolines with elastic ropes have large and protruding fixing components that can cause injuries, and the knotting or jointing processes are cumbersome and unsafe, leading to potential user injuries and instability during use.
Innovation Solution
A trampoline design featuring hanging seat units with closed ring-shaped elastic rope rings that connect to the bouncing unit via connection belts, allowing easy mounting and hiding of joints beneath the bouncing cloth, with thin and non-protruding components to prevent injuries and ensure safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If large and thick fixing components are used to improve structural strength, then the structural strength is improved, but the fixing components protrude out of the bouncing cloth surface and can cause user injuries
Solution Approach 1:
The elastic rope joint is nested inside the hollow spherical fixing component, with the joint positioned within the internal cavity of the sphere. This nesting arrangement allows the fixing component to provide structural strength while keeping the sharp joint hidden and non-protruding, thereby preventing user injuries.
Solution Approach 2:
The fixing component is designed as a hollow spherical shell with thin walls, providing sufficient structural strength while maintaining a compact, non-protruding profile. The spherical shell encloses the elastic rope joint, combining strength with safety.
2Reliability
If the two ends of each elastic rope are knotted into rings to form joints for fixing, then the fixing is achieved, but the early-stage work becomes troublesome and the sharp corners of joints cannot be hidden
Solution Approach 1:
The knotting operation is extracted from the mounting process. The elastic ropes are pre-knotted into rings during manufacturing, so that during installation only the simple operation of hanging the pre-formed rings on the fixing components is required, significantly reducing mounting complexity.
Solution Approach 2:
The elastic rope ends are pre-knotted into rings before installation. This preliminary action of forming joints during manufacturing rather than during installation simplifies the mounting process and ensures consistent, reliable fixing without requiring complex on-site knotting operations.
3Reliability
If fixing components with raised columns are used to hang elastic rope rings, then the elastic ropes can be fixed, but the raised columns cause user injuries
Solution Approach 1:
Instead of having protruding raised columns that extend outward to hang the elastic ropes, the design inverts the approach by using a hollow spherical component with an internal cavity. The elastic rope joint is hung inside the sphere through a through-hole, turning the fixing mechanism inward rather than outward, thereby eliminating protruding harmful elements.
4Reliability
If elastic ropes are wound repeatedly on raised columns and fixed with rings, then the fixing is achieved, but loosening and falling occur easily during use, compromising safety
Solution Approach 1:
The elastic rope rings are pre-formed with the joint positioned at a specific location before installation. During mounting, the ring is simply hung on the fixing component, ensuring proper positioning and tension from the start. This preliminary preparation prevents improper installation that could lead to loosening and falling during use.

AI summary
A trampoline with hanging seat units that allows elastic ropes to be mounted easily, comprises a frame, leg tubes, a bouncing unit, hanging seat units and elastic rope rings. The bouncing unit is hung on the frame and comprises a piece of bouncing cloth and connection belts. The hanging seat units are connected with the connection belts and each comprises a body, a through groove penetrating through the body, a connection body, an extension section, and a clamping and abutting section extending towards the bouncing cloth. The body, the extension section and the clamping and abutting section of each hanging seat unit define a clamping space. Each connection belt penetrates through the corresponding through groove. The bouncing unit and hanging seat units are connected through the elastic rope rings. The ends of each elastic rope ring are arranged in the corresponding connection belt and clamping space in a sleeved mode.
