Compact Slackline Structure With Elastic Main Body Dynamics
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, and conventional attachment systems are complex, costly, and prone to tension loss over time.
Innovation Solution
A compact slackline device design featuring a more elastic main body than webbing, where the main body's deformation dynamically varies the distance between fastening points, mimicking slackline behavior, and a simplified attachment system using plates or buckles for secure webbing connection without through-holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the webbing is stretched between two fixed points to provide dynamic movement behavior, then the slackline device can be used, but a large amount of space is required
Solution Approach 1:
The patent applies the dynamics principle by making the main body elastically deformable rather than rigid. The main body can dynamically change its shape and the distance between fastening points in response to user weight, providing the necessary movement behavior. This allows the slackline device to function with a compact form factor while maintaining the essential dynamic characteristics of traditional slacklines.
Solution Approach 2:
The patent changes the physical parameter of the main body by selecting materials and designs with specific elastic properties. The main body is designed to be more elastic than the webbing, allowing it to deform and recover, thereby changing the effective length and tension distribution. This parameter change enables the device to provide slackline-like behavior in a compact configuration.
2Reliability
If conventional attachment systems with sewn loops and dowels are used, then the slackline can be secured to the board, but the system becomes complex and requires multiple components
Solution Approach 1:
The patent merges the attachment function directly into the main body structure by providing integrated fastening elements (such as slots, channels, or recesses) that are built into the main body itself. This eliminates the need for separate components like sewn loops, dowels, and additional tensioning devices, thereby reducing overall system complexity while maintaining reliable tension maintenance.
Solution Approach 2:
The patent extracts the attachment function from the webbing and relocates it to the main body. Instead of adding complex attachment mechanisms to the webbing ends, the design integrates fastening features directly into the main body structure, simplifying the overall system by removing unnecessary intermediate components.
3Ease of operation
If the webbing is made more elastic to ensure dynamics, then certain movement behavior is achieved, but the extremely dynamic movement behavior is significantly changed
Solution Approach 1:
The patent applies local quality by differentiating the elastic properties between different components: the main body is designed to be more elastic than the webbing. This creates a localized elasticity gradient where the main body provides the primary dynamic response through its elastic deformation, while the webbing maintains its structural integrity and tension-carrying function. This local differentiation preserves the essential dynamic movement characteristics.
Solution Approach 2:
The patent inverts the traditional elasticity assignment by making the main body (usually a rigid support structure) more elastic than the webbing. This inversion allows the main body to deform and absorb energy, providing the necessary dynamics, while the webbing serves its traditional function of maintaining tension and providing a stable balancing surface.
4Weight of moving object
If a compact design with short webbing is used, then the device becomes portable, but the dynamic properties of the slackline are lost
Solution Approach 1:
The patent resolves this contradiction by implementing a dynamic main body that can elastically deform. The main body's ability to change shape and adjust the distance between fastening points dynamically compensates for the reduced webbing length. This allows the compact design to maintain portability while the elastic deformation of the main body preserves the essential dynamic properties needed for slacklining.
