Revolver Cam Mechanism Eliminates Cylinder Gap for Suppressor Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Revolvers are difficult to suppress due to the space between the cylinder and barrel, which allows noise from spent casings to escape, defeating the purpose of silence in covert operations and sport shooting in populated areas, and existing suppressors add weight and obstruct the user's view when enlarged for better noise reduction.
Innovation Solution
A revolver design with a cam mechanism that eliminates the gap between the cylinder and barrel upon firing, allowing gas to expand within a suppressor enclosed within the frame, featuring resonant chambers and a gas exit pathway to reduce noise, while maintaining the revolver's functionality and sight alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the space between the cylinder and barrel is maintained to allow cylinder rotation, then the revolver functions properly, but noise from spent casings escapes and suppression is defeated
Solution Approach 1:
The cylinder is made dynamically adjustable through a cam mechanism that changes its position relative to the barrel. During firing, the cam pushes the cylinder forward to eliminate the gap for noise suppression. During reloading, the cylinder is pulled back to create space for manual operation. This dynamic positioning resolves the contradiction between maintaining functionality and reducing noise.
Solution Approach 2:
The physical parameter of the cylinder-barrel gap is changed based on operational phase. The cam mechanism transforms the fixed gap into a variable parameter: minimal gap during firing for noise suppression, larger gap during reloading for functionality. This parameter change allows the system to satisfy both contradictory requirements at different times.
2Object-generated harmful factors
If the suppressor volume is increased to improve noise reduction, then suppression effectiveness increases, but weight increases and field of vision is blocked
Solution Approach 1:
Instead of uniformly increasing suppressor volume, the invention creates localized expansion chambers at specific positions within the suppressor. The resonant chambers are strategically positioned to target specific noise frequencies without requiring overall suppressor enlargement. This localized approach provides effective noise reduction while minimizing weight and visual obstruction.
Solution Approach 2:
The suppressor incorporates three-dimensional resonant chambers that expand noise suppression capability in additional spatial dimensions rather than simply increasing linear length. The internal chamber geometry creates volumetric noise cancellation without proportionally increasing external dimensions, thereby reducing weight and field of view blockage while maintaining suppression effectiveness.
3Adaptability or versatility
If the suppressor is made as a separate attachment to allow flexibility, then adaptability is improved, but device complexity increases and convenience is reduced
Solution Approach 1:
The suppressor is merged with the revolver frame into an integrated assembly rather than being a separate attachment. The cam mechanism, cylinder, and suppressor form a unified system where the cam's movement simultaneously controls both cylinder positioning and suppressor function. This merging reduces the number of separate components and simplifies the overall device while maintaining adaptability through the cam's operational phases.

AI summary
The present invention relates to a firearm with a frame, a trigger, a barrel entrance, a cam, and a revolving cylinder configured a gap distance from the barrel entrance. The firearm may have a suppressor with a bullet pathway that ends in a muzzle and a gas exit pathway that ends in a gas exit. The suppressor may have at least one resonant chamber. When the trigger of the firearm is pulled, the cam may contact the frame and the revolving cylinder to eliminate the gap distance. When a bullet is fired from the firearm, gas may follow a projectile portion of the bullet. The gas may expand within the suppressor. The at least one resonant chamber may bias the gas away from the muzzle. The gas may exit the firearm via a muzzle or via a gas exit.
