Cartridge Activation via Mechanical Feature Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing weapon systems lack effective mechanisms to ensure safe and appropriate use by preventing activation of unsuitable cartridges, which can lead to unintended or harmful outcomes, particularly in terms of lethality and interoperability with different types of cartridges and weapons.
Innovation Solution
A system that conditionally activates a cartridge based on compatibility between features of the activator and the cartridge, inhibiting activation if incompatibility is detected, using mechanical, electrical, or electromagnetic means to prevent improper use, thereby ensuring safe and appropriate deployment of force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a weapon system allows use with multiple types of cartridges, then versatility and adaptability are improved, but safety and control over lethality deteriorate
Solution Approach 1:
The patent divides the cartridge into distinct feature sets (e.g., first features and second features) that correspond to different weapon system types. This segmentation allows the system to maintain versatility by supporting multiple cartridge types while preventing unintended use by ensuring that only compatible weapon systems can activate each cartridge type, thus resolving the contradiction between versatility and safety control.
Solution Approach 2:
The patent introduces an intermediary activation mechanism that detects compatibility between the cartridge features and weapon system features before allowing activation. This intermediary layer acts as a mediator that enables versatile operation across different cartridge types while preventing harmful unintended activation by verifying compatibility, thus addressing both versatility and safety concerns.
2Reliability
If compatibility detection mechanisms are added to prevent incompatibility, then safety is improved, but device complexity increases
Solution Approach 1:
The patent implements self-service compatibility detection where the activation mechanism automatically detects and verifies compatibility between cartridge and weapon system features without requiring external intervention. The system self-verifies compatibility through feature detection (e.g., protrusions fitting into recesses), which improves safety while minimizing added complexity by eliminating the need for separate manual verification procedures.
3Object-affected harmful factors
If features are designed to be incompatible by default, then safety against misuse is improved, but ease of operation deteriorates
Solution Approach 1:
The patent applies local quality by designing specific localized features (protrusions and recesses) at particular locations on the cartridge and weapon system. These localized incompatible features are strategically positioned to prevent misuse while maintaining overall ease of operation for legitimate use, as the compatibility features align perfectly for proper installation while the incompatible features only engage when attempting improper use.

AI summary
A weapon conditionally activates a cartridge. The cartridge has a projectile and a first mechanical feature. The weapon includes an activator and a station. The activator includes a second mechanical feature. The station positions the cartridge so that the first feature opposes the second feature. On condition that the first feature does not mechanically interfere with the second feature, the activator activates the cartridge to launch the projectile from the cartridge. On condition that the first feature mechanically interferes with the second feature resulting in an excess head space, the activator is inhibited by the excess head space from activating the cartridge.
