Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for launching disc-like objects do not effectively rotate discs from a perpendicular to a parallel alignment with the longitudinal axis for discharge, lacking a robust and simple mechanism for reorientation.
Innovation Solution
A launch apparatus with a handle-operated mechanism that includes a rotatable disc pocket and spring-biased transfer and launch arms, allowing discs to be reoriented 90° from a perpendicular to a parallel position for discharge, featuring a drum with cylindrical chambers and a trigger for activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a robust mechanism is used to rotate discs from perpendicular to parallel alignment, then the reliability of disc discharge is improved, but the device complexity increases
Solution Approach 1:
The disc pocket combines multiple functions: it stores discs, rotates them 90 degrees from perpendicular to parallel alignment, and positions them for discharge. By merging these functions into a single component rather than using separate mechanisms for each function, the patent achieves reliable disc discharge while minimizing device complexity.
Solution Approach 2:
The disc pocket serves as a multi-functional element that handles disc storage, orientation change, and discharge positioning. This universal component eliminates the need for separate mechanisms to perform each function, thereby improving reliability without proportionally increasing complexity.
2Device complexity
If a simple mechanism is used to rotate discs, then the device complexity is reduced, but the ease of operation deteriorates
Solution Approach 1:
The spring-biased transfer arm automatically performs the complex task of removing discs from the drum and positioning them in the disc pocket without requiring manual intervention. The spring provides the necessary force to move the arm through its arc, enabling the mechanism to service itself and simplifying operation for the user.
Solution Approach 2:
The spring-biased transfer arm acts as an intermediary between the drum and disc pocket, automatically transferring discs between these components. This intermediary mechanism handles the complex coordination between different parts of the system, allowing the user to simply operate the handle while the transfer arm manages the disc movement.
3Ease of operation
If spring-biased transfer arms are used to move discs, then the ease of operation is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The transfer arm is designed to move dynamically through an arc motion rather than requiring precise static positioning. The spring provides continuous force throughout the movement, and the arm's arcuate path allows for gradual, forgiving positioning of the disc. This dynamic approach reduces the stringency of manufacturing precision requirements compared to a fixed, rigid positioning mechanism.

The apparatus is easy to operate, safe, and robust, enabling efficient discharge of soft foam circular projectiles, suitable for young children, while being structurally simple and cost-effective.
Implementation Method 1
a spring biased transfer arm pivotally mounted in the housing and operatively connected to the handle for sliding a disc from the disc container into the disc pocket
Implementation Method 2
a spring biased launch arm pivotally mounted in the housing and operatively connected to the handle, the launch arm being cocked when the handle is moved from the first position to the second position

AI summary
A toy pump action rifle for launching discs having an outer housing, a stock, a grip, a trigger, a handle for cocking the rifle and a revolving drum for storing multiple discs. Within the housing is a mechanism for removing discs, one at a time, from the drum where the discs are arranged in a first position, rotating each disc 90° to a second position, and transporting each disc to a discharge chamber. The mechanism includes a transfer arm to remove each disc from the drum, a disc pocket for receiving the removed disc, the pocket being rotatable to reorient the disc, and disc pocket also being slidable to carry the disc to the discharge chamber. Activation of the trigger releases a cocked launch arm that snaps forward and strikes the disc to cause discharge.
