Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable weapons lack a means to automatically or semi-automatically lock and unlock their firing sequences based on safe operational conditions, including time, place, direction, and operator, posing a significant safety risk.
Innovation Solution
A safety control system for portable weapons, utilizing sensors and microcontrollers to ensure safe operation by locking or unlocking the firing sequence based on vital signs, direction, biometric authentication, and environmental conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a primary safety lock mechanism is equipped on portable weapons, then unauthorized operation is prevented, but the mechanism can be manually released and provides no automatic safety control after release
Solution Approach 1:
The patent replaces manual mechanical safety control with an automated electronic control system. A microcontroller unit monitors multiple sensors (infrared sensors for breathing detection, motion sensors, position sensors) to automatically control the firing mechanism, substituting human judgment and manual intervention with electronic automation to maintain safety while enabling operation when conditions are safe
Solution Approach 2:
The safety control system performs self-monitoring and self-control functions. The microcontroller continuously reads sensor data regarding environmental conditions, operator state, and weapon position, then automatically adjusts the firing sequence control without external intervention, making the system self-regulating based on real-time conditions
2Adaptability or versatility
If manual safety lock release is allowed, then operational flexibility is maintained, but automatic or semi-automatic locking and unlocking based on safe conditions cannot be implemented
Solution Approach 1:
The patent implements dynamic safety control where the firing sequence control state changes automatically based on real-time sensor readings. The system transitions between locked and unlocked states dynamically according to environmental conditions, operator vital signs, and weapon positioning, rather than static manual control
Solution Approach 2:
The system incorporates multiple feedback loops where sensors continuously monitor conditions (infrared for breathing, motion sensors, position sensors) and feed this information to the microcontroller, which then adjusts the firing sequence control accordingly. This closed-loop feedback enables automatic adaptation to changing conditions
3Reliability
If multiple sensors and control mechanisms are added for automatic safety control, then operational safety is enhanced, but device complexity increases
Solution Approach 1:
The microcontroller serves multiple functions: it processes data from various sensors (infrared, motion, position), makes safety determinations, controls the firing sequence, and manages the overall system operation. By using a single multi-functional control unit rather than separate dedicated circuits for each function, the system achieves high reliability without proportionally increasing complexity
