Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Retrofitting AR-10 style firearms to accommodate larger caliber ammunition results in increased size and weight, making them difficult to handle and fire.
Innovation Solution
Modifications to the upper receiver, lower receiver, bolt carrier, charging handle, firing pin, and magazine well to accommodate cartridges between 73.66 mm and 91.44 mm in length without increasing the overall length and weight of the firearm.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If elongated components are used to retrofit AR-10 style firearm for larger caliber ammunition, then the firearm can fire larger caliber ammunition, but the overall length and weight of the firearm increase
Solution Approach 1:
The patent modifies specific dimensional parameters of existing components (upper receiver, lower receiver, bolt carrier, charging handle, firing pin) to accommodate larger caliber ammunition. By carefully adjusting these parameters within the existing component framework, the firearm can fire larger caliber rounds without requiring elongated components that would increase overall length.
Solution Approach 2:
The patent designs a universal modification system that allows the same modified AR-10 platform to accommodate multiple cartridge types within the 73.66-91.44mm length range. The modified components serve multiple functions: they maintain compatibility with existing magazines while enabling larger caliber ammunition, thus providing versatility without proportionally increasing size.
2Adaptability or versatility
If elongated components are used to retrofit AR-10 style firearm for larger caliber ammunition, then the firearm can fire larger caliber ammunition, but the weight of the firearm increases
Solution Approach 1:
The patent adjusts parameters of existing components (upper receiver, lower receiver, bolt carrier, charging handle, firing pin) to accommodate larger caliber ammunition. By modifying these components in-place rather than adding elongated parts, the patent achieves the ability to fire larger caliber rounds while maintaining the original weight characteristics of the AR-10 platform.
Solution Approach 2:
The patent combines the functionality of multiple components into integrated modifications. For example, the upper and lower receiver modifications work together with the bolt carrier and charging handle changes as a unified system, allowing larger caliber ammunition to be accommodated through coordinated parameter adjustments rather than separate additions, thereby avoiding weight increase.
3Adaptability or versatility
If elongated components are used to retrofit AR-10 style firearm for larger caliber ammunition, then the firearm can fire larger caliber ammunition, but the firearm becomes more difficult to handle and fire
Solution Approach 1:
The patent modifies parameters of existing operational components (upper receiver, lower receiver, bolt carrier, charging handle, firing pin) to enable larger caliber ammunition. By keeping the overall dimensions and component arrangements substantially the same while adjusting specific parameters, the patent maintains the ease of operation and handling characteristics of the original AR-10 platform.
Solution Approach 2:
The patent creates a universal modification system that maintains the original AR-10 operational characteristics while enabling larger caliber ammunition. The modified components are designed to work together in the existing configuration, preserving the familiar handling and firing dynamics of the original platform while providing the versatility to fire larger caliber rounds.
