Revolver Speed Loader Plunger Shaft and Rotating Disk Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional speed loaders for revolvers are inefficient and time-consuming, requiring multiple steps and components that limit the ability to load cartridges in a longitudinal arrangement, preventing the stacking of additional cartridges and necessitating the cylinder to be held stationary during loading.
Innovation Solution
A speed loader system featuring a plunger shaft that actuates the release of cartridges into a revolver cylinder, with an extender allowing for additional cartridges to be stacked longitudinally, and a rotating disk mechanism that enables quick loading and automatic return to a locked state without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional speed loaders use hand-rotated rods or screws located at the farthest end, then the device can load cartridges, but the device complexity increases and loading time is extended
Solution Approach 1:
The patent removes the complex hand-rotated rods or screws from the conventional speed loader design. Instead, it uses a simplified plunger shaft mechanism that directly pushes cartridges into the cylinder, eliminating unnecessary components and reducing device complexity while maintaining loading functionality
Solution Approach 2:
The patent inverts the conventional approach by positioning the actuating component (plunger shaft) at the first end of the device closest to the cylinder, rather than at the farthest end. This inversion allows for more direct force application and simpler mechanics, improving loading speed while reducing complexity
2Ease of operation
If conventional loading devices require the cylinder to be held stationary, then cartridges can be loaded, but the ease of operation decreases
Solution Approach 1:
The speed loader device is designed to self-align and self-load cartridges without requiring the user to manually hold the cylinder stationary. The plunger shaft mechanism automatically positions and pushes cartridges into the rotating cylinder, making the loading process simpler and easier to operate with one hand
3Quantity of substance
If conventional actuating rods and screws are used, then the device can function, but the cartridge capacity is limited to one row
Solution Approach 1:
The patent extends the cartridge arrangement from a single row to multiple rows by adding a second dimension to the cartridge storage. The plunger shaft mechanism is designed to push cartridges from multiple rows simultaneously into the cylinder, significantly increasing cartridge capacity while maintaining a relatively simple device structure
Solution Approach 2:
The plunger shaft mechanism is designed to perform multiple functions: it can load cartridges from a single row or multiple rows, and it can accommodate different cartridge arrangements. This multi-functionality increases cartridge capacity while avoiding the need for multiple separate loading mechanisms
