Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tracking systems for arrows, such as those using removable transmitters and electronic tracking systems involving drones and satellites, face challenges including potential interference with arrow penetration and complexity, which can affect the lethality of shots and efficiency in tracking moving targets.
Innovation Solution
A tracking system comprising a Base Unit, a Holding Magnet, and a Sending Unit with an electronic circuit that emits a tracking signal, where the circuit is maintained in a deactivated state by the magnetic field until the arrow hits a target, allowing the Sending Unit to separate and activate the signal without interfering with the arrow's trajectory.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a removable transmitter with a barbed hook is used to track the target, then the target can be tracked after being hit, but the transmitter interferes with the arrow's penetration and reduces lethality
Solution Approach 1:
The tracking system is divided into two separate components: a base unit that remains attached to the arrow shaft, and a sending unit that is propelled through the target. This segmentation allows the tracking functionality to be maintained while eliminating the interference caused by integrated transmitters, as the sending unit is small and streamlined for clean penetration.
Solution Approach 2:
The electronic circuit and battery are extracted from the arrow shaft and placed in a separate sending unit that is magnetically coupled to the base unit. This extraction removes the bulk of the tracking components from the arrow's path, allowing for clean penetration while maintaining tracking capability through the magnetically coupled sending unit.
2Loss of information
If electronic tracking systems involving drones and satellites are used, then comprehensive tracking information can be obtained, but the system complexity increases significantly
Solution Approach 1:
The sending unit serves multiple functions: it acts as both the arrow penetrator and the tracking signal source. The base unit provides both structural support and magnetic coupling for the sending unit. This multi-functionality eliminates the need for separate drone and satellite systems, achieving comprehensive tracking with minimal complexity.
Solution Approach 2:
The tracking system is self-contained and autonomous, requiring no external infrastructure. The sending unit automatically activates upon separation from the base unit and provides continuous tracking signals until battery depletion, eliminating the need for external drone or satellite intervention.
3Loss of information
If the electronic circuit is continuously active to provide tracking signals, then real-time tracking is achieved, but battery life is depleted quickly
Solution Approach 1:
The electronic circuit operates periodically rather than continuously. The magnetically coupled sending unit is activated only when separated from the base unit by a predetermined distance, creating periodic tracking signal emission that conserves battery life while maintaining effective tracking capability.
Solution Approach 2:
The magnetic coupling between the base unit and sending unit provides automatic feedback control. When the sending unit is close to the base unit, the magnetic field keeps the circuit deactivated. When separation occurs, the magnetic field weakens and automatically activates the circuit, eliminating the need for complex activation mechanisms and ensuring optimal battery usage.
