Telescopic Slackline Frame for Safe Height Adjustment on Slopes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slackline frames have safety risks due to protruding parts above the support plate, are not easily adjustable in height, and not suitable for slopes, and are not easily disassemblable for transportation.
Innovation Solution
A disassemblable and height-adjustable frame with telescopic carriers and a U-shaped slackline support plate, featuring convex and concave curved ends that interlock to maintain a symmetrical angle, and bearing elements for secure connection, allowing easy height adjustment and adaptation to slopes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the carriers protrude above the slackline support plate to provide adjustment range, then height adjustability is improved, but safety risk increases due to protruding parts
Solution Approach 1:
The carriers are designed as telescopic tubes that can dynamically adjust their length to change the height of the slackline support plate. The telescopic mechanism allows the carriers to extend and retract, providing height adjustability while retracting below the support plate level to eliminate safety hazards from protruding parts.
Solution Approach 2:
The carriers are divided into telescopic sections that can move relative to each other, allowing the effective length to be adjusted independently from the total structure. This segmentation enables the carriers to provide adjustment range while keeping the outer envelope compact and safe.
2Stability of the object's composition
If the frame structure is made rigid and fixed, then structural stability is improved, but ease of disassembly for transportation deteriorates
Solution Approach 1:
The frame is divided into modular components including telescopic carriers, a support plate, and a cross bar that can be independently connected and disconnected. The connecting elements allow for quick assembly and disassembly while maintaining structural integrity during use, enabling easy transportation and storage.
Solution Approach 2:
The frame transitions from a static fixed structure to a dynamic adjustable structure where the telescopic carriers can be extended or retracted, and the entire assembly can be quickly disassembled by removing connecting elements, providing both stability during operation and ease of transportation.
3Ease of manufacture
If the carriers are designed with simple straight geometry, then manufacturing simplicity is improved, but ability to maintain symmetrical angle and adapt to slopes deteriorates
Solution Approach 1:
The upper ends of the carriers are equipped with curved surfaces (convex on one carrier, concave on the other) that enable precise angular alignment and maintain a symmetrical configuration. These curved surfaces facilitate smooth rotation and positioning while adapting to slope conditions, adding functional complexity without significantly complicating manufacturing.

AI summary
A disassemblable and height-adjustable frame for slacklines has a slackline support plate which rests on two upwardly converging carriers that are connected to a cross bar at the base by connecting elements. The carriers are rectangular-shaped telescopic tubes. The slackline support plate, which is downwardly open in a U-shape, rests on the upper end of the carriers. The upper end of the front side of the carrier has a convex curved shape on the material side starting from the carrier surface facing the carriers in the operating position, and at the upper end of the rear side of the carrier has a concave curved shape on the material side starting from the surface facing the carriers in the operating position, which merges into a straight line and then forms a convex curve shape.
