Sling Shot Rifle Elastic Pouch Launch Consistency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sling shot rifles for shooting arrows or metal balls/pellets face issues due to uneven reactive forces from rubberized bands, causing projectiles to deviate from the intended flight path.
Innovation Solution
The design incorporates an elongated rail, a stock with a trigger mechanism, a resiliently stretchable pouch with a closed first end and an open second end, and a loop operatively coupled to the pouch's closed end, allowing for consistent and controlled projectile launch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If rubberized bands are used to propel projectiles, then the projectile can be launched with force, but the bands impart uneven reactive forces causing the projectile to deviate from the intended flight path
Solution Approach 1:
The single rubberized band is divided into multiple separate bands (typically three) that are arranged symmetrically around the central axis. Each band is anchored at different points on the arms and converges at a common attachment point on the pouch. This segmentation ensures that the reactive forces from each band are distributed evenly, preventing lateral deviation and keeping the projectile on the intended flight path while still providing sufficient launch force.
2Strength
If the pouch is made tightly confined at the closed end, then the projectile is contained securely, but it becomes difficult for the projectile to be released smoothly
Solution Approach 1:
The pouch is constructed with differentiated local properties: the closed end is made tightly confined and reinforced to securely contain the projectile during loading and cocking, while the open end is left loose and flexible to allow smooth projectile release. The transition zone between these regions is designed with gradual tapering to prevent snagging. This local quality differentiation ensures both secure containment and easy release without requiring complex mechanisms.

Function Achieved in This Case
This configuration ensures that the projectile is launched with consistent force, improving accuracy and allowing the user to hit their target more effectively by minimizing deviations caused by uneven band tension.
Implementation Method 1
a resiliently stretchable pouch having a closed first end and an open second end
Implementation Method 2
a spring-loaded locking pin operatively coupled to the slidable body, wherein the spring-loaded locking pin is configured to lock the slidable body to at least one particular position along the elongated rail

AI summary
An improved sling shot rifle has an elongated rail, a stock operatively coupled to a first end of the elongated rail, the stock comprising a trigger and a catch releasably coupled to the trigger. A resiliently stretchable pouch comprising a closed first end, an open second end configured to be operatively coupled to the elongated rail, and an insert comprising an insert body having a first end, an opposite second end, a cylindrical cavity formed in the insert body second end and a first diameter wherein the back of the axial cavity is configured to receive a back end of an arrow. The insert further comprises a flange formed on the insert body first end wherein the flange comprises a second diameter that is larger than the first diameter. A ring is positioned around an outside surface of the resiliently stretchable pouch proximate the resiliently stretchable pouch first end so that the ring is received around the insert body adjacent the flange. A loop is operatively coupled to the ring at respective points that are opposite from each other on the ring, wherein the loop is configured to be releasably coupled to the catch.
