Firearm Electronic Device Dormant Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearms with electronic devices require large energy sources for long-term functionality, leading to bulky power supplies that disrupt the gun's geometry and integration.
Innovation Solution
An electronic device integrated into the gun that activates only upon predefined events, such as extraction from a holster or hammer cocking, using a small lithium-ion battery that remains dormant until activated, minimizing energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a large battery is used to power the electronic device for long periods, then the duration of action is improved, but the volume and weight of the gun increase
Solution Approach 1:
The electronic device operates in periodic cycles: dormant state (low energy consumption) and active state (high energy consumption). The microprocessor remains dormant until triggered by a predefined event, then activates briefly to detect/process the event and return to dormant state. This periodic operation enables long-duration functionality with a small battery.
Solution Approach 2:
The system prepares for extended operation by maintaining the electronic device in a pre-charged but dormant state. The battery is fully charged in advance, and the microprocessor is programmed to activate only when needed, eliminating the need for frequent recharging while maintaining compact dimensions.
2Duration of action of moving object
If a large battery is used to power the electronic device, then the duration of action is improved, but the weight of the gun increases
Solution Approach 1:
The electronic device operates in periodic cycles: dormant state (minimal energy consumption) and active state (brief operation). The microprocessor remains dormant until triggered by a predefined event, then activates briefly to detect/process the event and return to dormant state. This periodic operation enables long-duration functionality with a small battery.
3Measurement precision
If the electronic device is always active, then the detection precision is improved, but the energy consumption increases
Solution Approach 1:
The electronic device operates in periodic cycles: dormant state (minimal energy consumption) and active state (brief operation). The microprocessor remains dormant until triggered by a predefined event, then activates briefly to detect/process the event and return to dormant state. This periodic operation enables long-duration functionality with a small battery.
Solution Approach 2:
The system uses the gun's own operational events (extraction from holster, hammer cocking) as automatic triggers to activate the electronic device. These predefined events serve as self-triggering mechanisms that activate detection only when relevant, eliminating the need for continuous monitoring while ensuring detection precision when needed.
