Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing manually operated projectile launching devices lack innovation and versatility for entertainment, target practice, hunting, and self-protection, with a need for devices that can utilize natural finger motion for efficient and accurate projectile launch.
Innovation Solution
A finger-mounted projectile launching device with a launch guide that utilizes the natural flicking or flinging motion of a finger, secured via various mechanisms like straps, sleeves, or clips, to hold and direct projectiles using centrifugal force and friction, allowing for adjustable launch angles to alter projectile trajectory and velocity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a spring mechanism is added to the finger-mounted device, then the projectile launch velocity and power are improved, but the device complexity increases
Solution Approach 1:
The spring mechanism is nested within the finger-mounted device structure, with the spring housed inside the device body and connected to the launch guide. This nesting approach allows the spring to be integrated without significantly increasing the external dimensions or visual complexity of the device, while still providing the power boost needed for higher projectile launch velocity.
2Ease of operation
If multiple securing mechanisms (straps, sleeves, clips) are provided, then the ease of operation and secure attachment are improved, but the device complexity increases
Solution Approach 1:
The device incorporates multiple types of securing mechanisms (straps, sleeves, clips) that can be used interchangeably to attach the device to different finger sizes and preferences. Each securing mechanism serves the same primary function of securing the device to the finger, but provides different methods for users to choose from, improving ease of operation without requiring completely separate devices for different users.
3Adaptability or versatility
If adjustable launch angles are provided, then the adaptability and versatility for different trajectories are improved, but the device complexity increases
Solution Approach 1:
The launch guide is designed with an adjustable angle mechanism that allows the user to change the launch angle dynamically between shots. The launch guide can be rotated or pivoted to different angles and locked into position, enabling the same device to adapt to different trajectory requirements without requiring multiple fixed-angle guides or complex reconfiguration mechanisms.

AI summary
A digit-mounted, spring-assisted device for launching a projectile in response to a launching motion of a finger by a user. The digit-mounted device may comprise a securing means for securing a launcher to the digit of the user. The securing means may comprise a strap, loop, or cinch. The digit-mounted device may further comprise a launch guide extending outwardly from a base member. A projectile may be mounted onto or into the launch guide. A spring may be mounted on the digit-mounted device which is placed under tension when the user prepares to make a launching motion with the digit. The projectile is launched in response to the user making a launching motion with the digit, using the thumb as a tensioning means. The spring is released from tension upon making a launching motion with the digit, adding to the force given to the projectile upon launch. The projectile may take a wide variety of forms.
