Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices for firearms are large and cumbersome, making them difficult to integrate into handguns and affecting the firearm's geometry and behavior, as they require large power supplies for effective and long-term operation.
Innovation Solution
An electronic device comprising a firearm element with detection and processing means for events like shot firing, and a base element with a charging battery that recharges the power supply battery via a specialized interface port system, allowing for compact and secure power management within the firearm.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a large-sized power supply battery is used to ensure effective and long-term operation, then the duration of action is improved, but the volume and weight of the device increase
Solution Approach 1:
The power supply system is segmented into two parts: a small power supply battery integrated in the firearm element for portable operation, and a separate charging battery in the base element for recharging. This segmentation allows the firearm to remain compact while providing extended operational capability through periodic recharging at the base station.
Solution Approach 2:
The base element acts as an intermediary between the external environment and the firearm element. It contains a charging battery that wirelessly or contactlessly transfers energy to the firearm's power supply battery when docked, eliminating the need for a large integrated battery while ensuring continuous operation.
2Duration of action of moving object
If a large-sized power supply battery is used to ensure effective and long-term operation, then the duration of action is improved, but the device complexity increases
Solution Approach 1:
By separating the power supply and charging functions into different elements (firearm element and base element), the complexity of managing a large battery is transferred to the stationary base, keeping the portable firearm simple while enabling extended operation through periodic recharging.
3Reliability
If a specialized interface port system is used for recharging, then the reliability of recharging is improved, but the device complexity increases
Solution Approach 1:
The interface port serves multiple functions: mechanical docking alignment, electrical contact for power transfer, and data communication. By merging these functions into a single integrated interface between the firearm element and base element, the system achieves reliable recharging without proportionally increasing complexity.
Solution Approach 2:
The interface port is designed as a multi-functional universal connector that handles both power recharging and data transmission between the firearm element and base element, reducing the need for separate specialized connections and simplifying the overall interface design.
