Hand Cannon Elastic Propulsion for Multi-Projectile Launching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projectile launching weapons are limited to a single type of projectile and are not well-suited for outdoor use, as they can suffer from rust and grime damage due to exposure to inclement weather conditions, lacking durability and versatility.
Innovation Solution
A handheld slingshot-type weapon, referred to as a hand cannon, utilizing a tubular body with attached elastic to propel various projectiles, featuring a single-piece construction for durability and ease of use, with a funnel and tube design for improved accuracy and a lack of complex parts to resist weather degradation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional projectile launching weapons are used, then they can launch projectiles with high speed and accuracy, but they are limited to a single type of projectile and require multiple weapons for different projectiles
Solution Approach 1:
The hand cannon is designed with a universal tubular body and elastic propulsion mechanism that can accommodate multiple types of projectiles including bullets, arrows, and other projectiles. The tubular body serves as a multi-functional chamber that can hold different projectile types, while the elastic band provides a universal propulsion method for all projectile types, eliminating the need for multiple specialized weapons
2Reliability
If traditional weapons with metal parts like springs are used, then they can provide reliable projectile launch, but they are susceptible to rust and grime damage from weather exposure
Solution Approach 1:
The invention extracts and eliminates vulnerable metal spring parts from the launch mechanism. Instead of using traditional metal springs that rust and degrade from weather exposure, the design uses a simple elastic band made from weather-resistant materials like rubber or latex. This extracted simplification removes the harmful vulnerability to rust and grime while maintaining the essential elastic propulsion function
Solution Approach 2:
The material parameters of the propulsion element are changed from metal springs to elastic bands made of weather-resistant materials. This parameter change in material composition transforms the launch mechanism from one susceptible to oxidation and corrosion to one that can withstand outdoor weather conditions including moisture, rain, and temperature variations
3Manufacturing precision
If complex multi-part weapons are used, then they can provide precise projectile launch control, but they require proper storage and cleaning to prevent degradation
Solution Approach 1:
The design segments the weapon into simple, separable components: a tubular body and an elastic band. This segmentation allows the elastic band to be easily removed, replaced, or cleaned independently from the tubular body. The simplicity of each segment reduces the complexity of maintenance while preserving the precision of the launch mechanism through proper component design
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 hand cannon provides a versatile, durable, and accurate means to launch multiple types of projectiles with adjustable velocity and distance, resisting weather-related damage through its simple and robust design, enhancing usability in hunting and fishing scenarios.
Implementation Method 1
The elastic band is pulled back and held in place against the funnel, storing elastic energy. When released, the elastic energy is converted to kinetic energy, propelling the projectile forward at high speed.

AI summary
A multi-use projectile launching apparatus that includes a single piece body and attached elastic propulsion band to propel an object through a portion of the single piece body. The single piece body consists of a handle for supporting the apparatus, a projectile tube through which the propelled object travels, a funnel for receiving the propelled object and passing it to the projectile tube, and one or more attachment nodes for connecting an elastic propulsion band to the single piece body. Together these components form a device capable of launching several kinds of projectile objects at high speed by propelling the projectile object with elastic force.
