Tamper-Resistant Strap and Remote Siren Control for Wireless Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems for tracking and communicating with individuals, such as children, lack improved security features that prevent the remote receiver unit from being removed or tampered with, while also providing effective tracking and communication capabilities.
Innovation Solution
A wireless communication system comprising a hand-held transmitter and a remote receiver unit with a tamper-resistant strap and a siren that can be actuated and volume-controlled remotely, ensuring the remote receiver unit cannot be easily removed and providing reliable tracking and communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the remote receiver unit is made easily removable for convenience, then ease of operation is improved, but security and reliability deteriorate
Solution Approach 1:
The strap transitions from a static attachment to a dynamic system with multiple states: normal wear mode with tamper-resistant features, and emergency release mode. The emergency release mechanism allows the strap to dynamically change its security properties based on the situation, maintaining security during normal use while enabling quick release when needed.
Solution Approach 2:
The tamper-resistant strap changes its mechanical properties based on activation state. When the emergency release button is pressed, it triggers a parameter change in the strap's structural integrity, allowing it to transition from a secure, difficult-to-remove state to an easily removable state, thus resolving the contradiction between security and ease of operation.
2Productivity
If the siren volume is increased for better communication, then communication effectiveness is improved, but energy consumption increases
Solution Approach 1:
Instead of continuous high-volume siren operation, the system uses periodic activation with variable duration and intensity. The hand-held transmitter can trigger the siren for specific time intervals at adjusted volume levels, achieving communication effectiveness while minimizing energy consumption through intermittent rather than continuous operation.
Solution Approach 2:
The siren system transitions from a static, fixed-volume operation to a dynamic system where volume and duration can be adjusted in real-time based on communication needs. The hand-held transmitter enables dynamic control of siren parameters, allowing optimal balance between communication effectiveness and energy conservation.

AI summary
A wireless communication system includes a hand-held transmitter for selectively transmitting at least one wireless signal, and a remote receiver unit including a remote receiver mounted to a strap and receiving the wireless signal. The remote receiver includes a sound generator which is actuated and volume adjusted using the hand-held transmitter, dependent on the wireless signal.
