Releasable-Insert Projectile for Deeper Impact Penetration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projectiles often lack sufficient momentum and penetration to effectively bring down animals during hunting, particularly in bear hunting, where they may not strike vital organs, leading to potentially life-threatening situations for hunters.
Innovation Solution
A projectile device featuring a shroud with a channel and a releasable insert, where air flow restriction enhances penetration, combined with a metal shroud and plastic insert, and a flighted member for rotation upon impact, allowing for increased cutting power and penetration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a traditional projectile is used, then the structure is simple, but the penetration capability and momentum on impact are insufficient
Solution Approach 1:
The projectile is divided into two main segments: a shroud (outer casing) and an insert (inner core). The insert is releasably secured to the shroud, allowing it to be released during impact to increase penetration. This segmentation allows each part to have optimized functions while maintaining overall structural integrity during flight.
Solution Approach 2:
The projectile incorporates dynamic elements including: (1) The insert is releasably secured to allow it to separate from the shroud during impact based on air pressure and force conditions; (2) The flighted member is designed to rotate the projectile upon impact with the target; (3) The air channel allows air flow to build pressure for releasing the insert. These dynamic features enable the projectile to adapt its structure during impact to maximize penetration.
2Ease of manufacture
If the projectile structure is simplified, then manufacturing is easier, but the ability to rotate and cut through the target is reduced
Solution Approach 1:
The flighted member is designed as a separate component that can be attached to the shroud, allowing for simplified manufacturing of individual parts while achieving the complex rotating cutting action when assembled and deployed together during impact.
3Force
If the projectile has increased mass for more momentum, then penetration improves, but the projectile becomes harder to control during flight
Solution Approach 1:
The projectile concentrates mass strategically in the insert (inner core) rather than uniformly distributing it. The insert can be made of dense material to provide momentum, while the overall projectile geometry and air channel design maintain aerodynamic properties for controlled flight. The localized mass concentration achieves momentum without compromising flight control.
4Stability of the object's composition
If the projectile penetrates deeply without releasing components, then structural integrity is maintained, but penetration depth and cutting effectiveness are limited
Solution Approach 1:
The insert is releasably secured to the shroud in advance of impact, with the release mechanism pre-configured to activate under impact conditions (air pressure buildup, force application). This preliminary arrangement allows the projectile to maintain integrity during flight while being prepared to separate at the moment of impact to maximize penetration depth.
Solution Approach 2:
The projectile transitions from a static, integrated structure during flight to a dynamic, separable structure during impact. The air channel and releasable securation create a dynamic system where the insert separates from the shroud based on impact conditions, enabling deeper penetration while maintaining structural integrity during the approach phase.
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 projectile achieves enhanced penetration and cutting power, ensuring rapid disablement of the animal and providing a clear blood trail for easy tracking, thereby ensuring hunter safety.
Implementation Method 1
a flow of air flowing through the forward end of the shroud through the channel is restricted by the insert
Implementation Method 2
forward momentum of the shroud causes the forward end of the shroud to cut a column from the target
Implementation Method 3
the flighted member cooperates with the target so that the projectile rotates and cuts through the target
Data Source
AI summary
A projectile device is disclosed for firing at a target. The projectile device includes a shroud, the shroud having a forward end and a rearward end. The shroud defines a channel which extends through the shroud between the forward end and the rearward end of the shroud. An insert is releasably secured to the shroud such that after the forward end of the shroud strikes the target, the insert is released from the shroud for increasing penetration of the shroud through the target.
