Eccentric Ring Launching Member for Stable Flight Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sports and game products involving sticks and rings lack a design that enhances the throwing and catching mechanism, resulting in inefficient rotation and stability of the ring device during launch.
Innovation Solution
A combination of a stick and a ring device with a ring launching member having a larger cross-sectional area towards its base, an eccentric ring support extension, and a stop member, which allows the ring device to be launched eccentrically, creating rotation similar to a frisbee, with the ring device supported in a pre-launch position that engages the ring launching member asymmetrically, ensuring stable flight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the ring device is launched symmetrically from the center of the ring launching member, then the launching mechanism is simple, but the rotation and stability of the ring device during flight is insufficient
Solution Approach 1:
The ring launching member features an eccentric ring support extension that supports the ring device at an offset position from the central axis, creating asymmetric engagement. This asymmetric support point generates rotational torque during launch, causing the ring device to rotate consistently during flight while maintaining stability, directly resolving the contradiction between simple launching mechanism and stable rotating flight.
2Stability of the object's composition
If the ring launching member has a uniform cross-sectional area, then the manufacturing is simpler, but the rotation control and stability of the ring device is reduced
Solution Approach 1:
The ring launching member has a cross-sectional area that varies along its length, being larger at the base and smaller at the tip. This non-uniform cross-section is concentrated at the base where structural support is needed, while the tip remains slender for proper ring engagement. This local variation in cross-sectional area provides both the structural integrity needed for rotation stability and the manufacturing efficiency of keeping most of the member slender.
3Speed
If the ring device is launched without eccentric support, then the launching mechanism is simpler, but the rotation speed and consistency is insufficient
Solution Approach 1:
The eccentric ring support extension creates an asymmetric support configuration where the ring device is supported at a point offset from the central axis. This asymmetric positioning generates consistent rotational torque during the launching motion, producing reliable rotation speed and consistency. The eccentric geometry converts linear launching motion into rotational motion efficiently, achieving high rotation speed without complex mechanical components.
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 design enhances the rotation and stability of the ring device during launch, allowing for a more spectacular and efficient throwing and catching experience, with the ring device rotating slowly but consistently, maintaining a stable flight position.
Implementation Method 1
The ring launching member is constructed to support the ring device in a launching position, wherein in the launching position a center of the ring device is offset with respect to the axis. The eccentric ring support extension is constructed to support the ring device in an eccentric position relative to the ring launching member axis. This eccentric position creates rotation during the launch.
Implementation Method 2
The eccentric position of the ring device may be a driving factor of the rotation of the ring device during the launch. This can be compared to the launch of a frisbee. When throwing the frisbee, the user holds the frisbee eccentrically, i.e. at a distance from the center of gravity of the frisbee. When throwing the frisbee, the frisbee starts to rotate as a result of the eccentric force of the hand of the thrower.
