Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing entertainment devices for creating a thrilling experience are complex, costly, and lack adequate safety features, particularly when used in outdoor settings without a reliable power source.
Innovation Solution
A pivoting frame device with a threaded spindle and counterweight mechanism, combined with safety features like nets, side walls, and sensors, allows for safe and economical operation, even in the absence of a power source, by using a motor or crank for adjustment and incorporating self-locking thread pitch and lever mechanisms for optimal torque distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hydraulic cylinders are used to adjust the pivoting frame, then the device can achieve precise positioning and control, but the device complexity and cost increase significantly
Solution Approach 1:
The patent replaces the hydraulic cylinder system with a threaded spindle mechanism. The threaded spindle converts rotational motion into linear displacement, providing precise positioning through mechanical means rather than hydraulic control. This substitution eliminates the need for complex hydraulic systems while maintaining positioning accuracy through the self-locking property of the threaded spindle.
Solution Approach 2:
The threaded spindle with self-locking thread pitch provides automatic position holding without requiring continuous power or complex control systems. Once positioned, the mechanism maintains its position through its inherent mechanical properties, reducing the need for active control and monitoring systems.
2Stability of the object's composition
If a fixed plate is used for the person to stand on, then structural stability is improved, but the thrilling experience and hygiene are compromised
Solution Approach 1:
The patent replaces the fixed plate with a net or grid structure. This porous configuration allows air circulation through the structure, preventing moisture accumulation and reducing germ growth. The net structure maintains structural stability while providing the desired thrilling experience through its flexibility and the visual effect of exposure.
3Speed
If the pivoting frame is adjusted without a self-locking mechanism, then the adjustment speed is increased, but safety is compromised due to uncontrolled swinging
Solution Approach 1:
The threaded spindle with self-locking thread pitch automatically maintains the positioned state without requiring continuous power or active control. The self-locking mechanism prevents uncontrolled swinging and maintains safety during power failures through its inherent mechanical properties, eliminating the need for additional braking or locking systems.
4Stability of the object's composition
If the device is designed for permanent installation only, then structural stability is improved, but adaptability for temporary events is reduced
Solution Approach 1:
The device is designed as a modular system with the fixed frame serving as the stable anchor point while the pivoting frame and net structure can be independently assembled and disassembled. This segmentation allows the device to be installed temporarily on suitable structures and easily removed when no longer needed, providing both structural stability during use and adaptability for temporary events.
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 device provides a thrilling experience with enhanced safety and simplicity, ensuring stable operation during power outages and reducing material fatigue, while being compact and suitable for temporary events.
Implementation Method 1
By means of the at least one threaded spindle, considerable reduction ratios can be achieved, so that even drives with low torque are sufficient to adjust the at least one pivoting frame.
Implementation Method 2
The at least one threaded spindle has a self-locking thread pitch, so that if the drive torque fails, the at least one pivoting frame remains in its position.
Implementation Method 3
In order to keep the load on the drive low, the at least one pivoting frame can be coupled to at least one counterweight in order to reduce the load on the at least one drive.

AI summary
A device (1) is used for restraint. It has a fixed frame (2) to which a pivoting frame (3) is articulated about an approximately horizontal pivot axis (4). This pivoting frame (3) can be pivoted between a substantially vertical closed position and a pivoted exposure position. A net (5) or grid is held in the pivoting frame (3), on which the person lies in the exposure position. The pivoting frame (3) is adjustable by means of at least one threaded spindle (8) with a self-locking thread pitch.
