Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current firearm barrel cleaning methods are time-consuming and often neglected due to the inefficiency of existing shoot-through bore cleaning devices, which waste compressive force by using rigid frames that are prone to deformation, reducing the effectiveness of cleaning materials in reaching and cleaning the bore surface.
Innovation Solution
A frameless ballistic barrel cleaning device utilizing a stack of cleaning materials with a solid, non-hollow core cylindrical shape, propelled by a propellant, that maximizes compressive force to deform radially and effectively scrub the bore surface, ensuring intimate contact and efficient debris removal without the inefficiencies of rigid frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid frame is used to connect cleaning materials in a shoot-through bore cleaning device, then the structure provides structural support, but the rigid frame deforms under compressive force reducing the effectiveness of cleaning materials
Solution Approach 1:
The patent removes the rigid frame component entirely from the cleaning device. Instead of using a frame to hold cleaning materials, the invention uses a flexible membrane that can deform under compression to directly contact and clean the bore surface, eliminating the frame's negative effect on cleaning effectiveness
Solution Approach 2:
The patent employs a flexible membrane instead of a rigid frame to hold and transmit force to the cleaning materials. This flexible shell allows the structure to deform under compressive force while maintaining integrity, enabling the cleaning materials to be pushed against the bore surface with maximum force without being lost to frame deformation
2Shape
If a rigid frame is used to hold cleaning materials, then the structure maintains shape, but compressive force is wasted deforming the frame rather than cleaning the bore
Solution Approach 1:
The flexible membrane serves as a force transmission medium that can change shape under compression without wasting energy. Unlike a rigid frame that deforms elastically and dissipates energy, the membrane transmits compressive force efficiently to the cleaning materials while maintaining its containment function
Solution Approach 2:
The patent changes the mechanical properties of the structural component from rigid to flexible. This parameter change allows the membrane to adapt its shape under different force conditions, optimizing force transmission to cleaning materials while preventing energy loss through frame deformation
3Reliability
If traditional cleaning methods are used, then thorough cleaning can be achieved, but the process is time-consuming and often neglected
Solution Approach 1:
The cleaning device is designed to be self-actuating, using the firearm's own recoil or gas pressure to propel the cleaning materials through the bore. This eliminates the need for manual operation or additional power sources, making the cleaning process automatic and integrated into the firearm's normal operation
Solution Approach 2:
The shoot-through design allows cleaning materials to be rapidly propelled through the entire bore length in a single pass, completing the cleaning task in seconds rather than requiring prolonged manual scrubbing. The high-speed passage of cleaning materials through the bore achieves thorough cleaning without time-consuming manual intervention
