Firearm Cartridge Package with Thermochromic Trajectory Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packages for firearm cartridges do not account for temperature effects on bullet trajectory, which can significantly impact shooting accuracy, especially at varying temperatures not corresponding to the calibration temperature, leading to inaccurate shooting.
Innovation Solution
The package incorporates intelligent printings on the container element or label that display the temperature effect on bullet trajectory at specific temperatures or temperature ranges, allowing shooters to correct for temperature variations, with options for curve or table formats and a releasable label for convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional labeling is used without temperature information, then the package structure remains simple, but shooting accuracy deteriorates due to lack of temperature correction data
Solution Approach 1:
The patent pre-calculates and prints trajectory correction values for multiple temperature conditions directly on the package label before the shooter needs them. This preliminary preparation ensures that accurate temperature correction information is immediately available when needed, eliminating the need for complex calculations or external references during shooting.
Solution Approach 2:
The patent creates a simplified copy of the trajectory data by printing essential correction values directly on the package label rather than requiring access to detailed trajectory tables or computational tools. This copied information provides shooters with the critical temperature correction data in an accessible, portable format that can be used directly in the field.
2Loss of information
If comprehensive trajectory information is printed for all temperatures, then temperature correction availability improves, but label complexity and information overload increases
Solution Approach 1:
The patent applies local quality by providing different levels of information for different temperature conditions. Instead of uniformly detailed tables for all temperatures, the label presents simplified correction values specifically tailored to common shooting temperature ranges, giving shooters the appropriate level of detail without overwhelming them with unnecessary data.
Solution Approach 2:
The patent segments the trajectory information by temperature ranges, presenting correction data in distinct sections or formats for different temperature conditions (e.g., cold, moderate, hot). This segmentation allows shooters to quickly locate and use only the information relevant to their current environmental conditions, reducing cognitive load and improving usability.
3Loss of information
If the label is permanently attached to the container, then information availability is ensured, but flexibility and portability deteriorates when shooters need to take only some cartridges
Solution Approach 1:
The patent implements a dynamic labeling system where the label can transition between different attachment states. The label is designed to be releasably attachable to the cartridge container, allowing it to remain attached when the full container is stored (ensuring information availability) but be easily removed and transferred when shooters take only some cartridges (providing portability and flexibility).
Solution Approach 2:
The patent changes the attachment parameter of the label from fixed to variable. By using releasable attachment mechanisms, the label's connection strength and position can be adjusted based on usage needs, enabling shooters to maintain information access when storing cartridges while easily transferring the label to smaller groups of cartridges when carrying only a portion of the supply.
