Trampoline Cord Loop Connection for Stable Elastic Suspension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection arrangements for mini trampolines are prone to cord movement, are complex, and difficult to maintain, making them unreliable and challenging to use.
Innovation Solution
A connection arrangement featuring a cord holding part and a receiving part that form a loop, allowing the cord to wrap around the trampoline frame, providing a secure and compact design that minimizes torque forces and allows for easy assembly and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing connection arrangements are used to connect the mat to the frame, then the trampoline can be assembled, but the cord is prone to movement during use and the structure becomes complex
Solution Approach 1:
The connection arrangement is divided into separate functional parts: a cord holding part with holes for securing cord ends, and a receiving part that receives the cord holding part. This segmentation allows each part to perform its specific function efficiently while maintaining overall simplicity.
Solution Approach 2:
The cord holding part is inserted into and nested within the receiving part, forming a compact integrated connection structure. This nesting arrangement secures the cord holding part in place while maintaining ease of assembly and disassembly.
2Ease of repair
If existing connection arrangements are used, then the trampoline structure is complete, but the connection is difficult to maintain and replace
Solution Approach 1:
The connection arrangement is divided into separate functional parts: a cord holding part with holes for securing cord ends, and a receiving part that receives the cord holding part. This segmentation allows each part to perform its specific function efficiently while maintaining overall simplicity.
Solution Approach 2:
The connection arrangement allows for dynamic assembly and disassembly. The cord holding part can be easily inserted into and removed from the receiving part, enabling quick maintenance and replacement without complex tools or procedures.
3Force
If a metal spring suspension is used, then high acceleration forces are allowed, but the deceleration is harsh and unsuitable for rehabilitation purposes
Solution Approach 1:
The patent changes the physical parameters of the suspension element from rigid metal springs to elastic cords with controlled elasticity. This parameter change allows the suspension to provide both sufficient acceleration force and gentle deceleration, making it suitable for rehabilitation and fitness purposes.
Solution Approach 2:
The suspension system uses elastic cords made from composite or specially formulated materials that provide both strength and controlled elasticity. These materials allow the cord to stretch and recoil smoothly, providing gentle deceleration while maintaining the necessary force for effective exercise.
4Object-affected harmful factors
If an elastic strap ring suspension is used, then softer deceleration is achieved, but the connection structure becomes more complex
Solution Approach 1:
The connection arrangement is divided into separate functional parts: a cord holding part with holes for securing cord ends, and a receiving part that receives the cord holding part. This segmentation allows each part to perform its specific function efficiently while maintaining overall simplicity.
Solution Approach 2:
The cord holding part is inserted into and nested within the receiving part, forming a compact integrated connection structure. This nesting arrangement secures the cord holding part in place while maintaining ease of assembly and disassembly.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a reliable, easy-to-use connection that keeps the cord in place, reduces stress on the trampoline structure, and allows for controllable bouncing effects, improving safety and durability while lowering manufacturing costs.
Implementation Method 1
The elastic suspension comprises members or elements that may be any kind of rope or cord with elastic qualities, permitting the spring members to stretch when pulled or compress when pushed.

AI summary
In this disclosure a connection arrangement for a trampoline is set out, the arrangement including a mat and a frame. The connection arrangement includes a cord and a security piece, which includes a receiving part and a cord holding part. The cord holding part is configured to receive both ends of the cord and thus forming a loop that includes the cord and the cord holding part. The receiving part receives the cord holding part and one end of the loop through an opening. The loop is configured to wrap around some horizontal part of the frame of the trampoline when the connection arrangement is fitted onto the frame.
