Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in ballistics is to accurately predict and adjust the trajectory of a projectile due to temperature variations in the gun barrel, which can affect muzzle velocity and barrel integrity over time.
Innovation Solution
A system that includes temperature sensors within the gun barrel to measure temperature profiles, which are then used by a processor to generate instructions for the marksman to adjust their aim, taking into account the effects of temperature on barrel harmonics and bullet trajectory.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If temperature sensors and processing systems are added to measure and compensate for barrel temperature, then trajectory accuracy is improved, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical temperature compensation mechanisms with an electronic system consisting of temperature sensors, a processor, and optical indicators. This substitution of mechanical/physical compensation methods with electronic measurement and control systems resolves the contradiction by achieving high measurement precision through digital processing while managing device complexity through integrated electronics rather than complex mechanical adjustments
Solution Approach 2:
The system enables the firearm to self-monitor and self-compensate for temperature effects through integrated temperature sensors that continuously measure barrel temperature and automatically trigger aim adjustment indicators. This self-service approach improves trajectory accuracy without requiring external intervention or complex manual compensation procedures, thereby reducing operational complexity
2Measurement precision
If multiple temperature sensors are installed within the barrel to measure temperature profiles, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent divides the barrel into multiple measurement zones by installing multiple temperature sensors at different locations along the barrel length. This segmentation allows precise measurement of temperature profiles at critical points, improving measurement precision while managing complexity through distributed, modular sensor placement rather than requiring a single complex measurement system
Solution Approach 2:
The temperature sensors serve multiple functions: measuring temperature at different barrel zones, tracking temperature changes over time during firing sequences, and providing data for compensation calculations. This multi-functionality improves measurement precision for trajectory prediction while reducing overall system complexity by eliminating the need for separate measurement and monitoring systems
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enables more accurate and consistent projectile trajectories by accounting for temperature-induced changes in the gun barrel, thereby improving marksmanship and reducing barrel wear.
Implementation Method 1
Friction and the pressure between the bullet, the casing, and the barrel may cause heat to be generated, and that heat is conducted through the gun barrel
Implementation Method 2
the barrel increases in temperature because of the friction of the bullet and the pressure of the charge propelling it
Data Source
AI summary
An apparatus, system, computer-readable medium, and/or process to measure, sense, or otherwise determine temperature of a gun barrel (e.g., temperature profile) and use that information to generate instructions to adjust aim of the gun before, during, or after (e.g., next shot) shooting the gun. For example, a gun includes several (e.g., 4, 5) temperature sensors within its barrel that measure the temperature profile of a gun barrel after it is shot (e.g., each time it is shot or after several shots); and these sensors provide their measurements to a processing unit (e.g., CPU, GPU) and the processing unit uses these temperature measurements to generate a temperature profile. In at least one embodiment, the temperature profile may then be used to generate one or more predictions and/or instructions for a user.
