Portable Slackline Frame Using Elastic Body Instead of Long Webbing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slackline devices require a large amount of space due to the need for long webbings stretched between fixed points, limiting their portability and versatility, and they lack a compact design that maintains dynamic movement behavior.
Innovation Solution
A slackline device with a main body that is more elastic than the webbing, allowing the main body to deform and vary the distance between its end portions, simulating the dynamic properties typically provided by webbing elongation, thus enabling a compact and portable design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the webbing is tensioned across a long distance to enable dynamic properties, then the dynamic movement behavior is provided, but the device requires a relatively large amount of space
Solution Approach 1:
The patent changes the elasticity parameter distribution in the system by making the main body significantly more elastic than the webbing. This parameter change allows the system to achieve dynamic movement behavior with a much shorter webbing length (less than 1 meter) compared to traditional slacklines that require 10 meters or more, thus reducing the space requirement while maintaining adaptability
Solution Approach 2:
The patent inverts the traditional approach by making the support structure (main body) elastic rather than making the webbing elastic. In traditional slacklines, the webbing provides elasticity; in this invention, the main body provides elasticity while the webbing remains relatively inelastic. This inversion allows compact design while preserving dynamic properties
2Adaptability or versatility
If the webbing is made more elastic to ensure dynamics in compact design, then the dynamic properties are maintained, but the movement behavior is significantly changed
Solution Approach 1:
The patent precisely controls the elasticity parameter relationship between components, making the main body's elasticity modulus significantly higher than the webbing's elasticity modulus. This parameter control ensures that the webbing remains taut and provides consistent movement behavior, while the main body's elasticity compensates for the reduced webbing length, maintaining dynamic properties without significantly altering the characteristic slackline movement

AI summary
A slackline device comprising a main body having at least one bearing portion and two mutually opposite end portions which are disposed so as to be elevated in relation to the at least one bearing portion, and comprising a webbing which in an assembled state of the slackline device is tensioned between the two end portions of the main body. The slackline device is preferably portable. Strictly speaking, the slackline device disclosed herein is not a slackline in the actual sense, but is a device that is designed to realistically imitate the behavior of a slackline for the user.
