Dual-Transmitter Emergency Alert Device Connectivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable emergency alert devices face connectivity issues, as they often rely on either radio hubs at home or mobile phones, which may not be consistently available, and have limited battery life, requiring frequent recharging or replacement.
Innovation Solution
A portable emergency alert device with dual communication transmitters, including a radio transmitter for home use and a Bluetooth transmitter for mobile use, ensuring connectivity both at home and outside, and a long-lasting battery that lasts for at least one year without recharging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single transmitter (radio or Bluetooth) is used in emergency alert devices, then the device structure is simple, but connectivity reliability deteriorates because the device may not be consistently available when needed
Solution Approach 1:
The patent combines two different transmitter systems (radio transmitter and Bluetooth transmitter) into a single emergency alert device. This merging of communication technologies ensures that the device can connect through multiple pathways - using radio transmission when at home near a hub, and Bluetooth transmission when mobile with a smartphone - thereby significantly improving connectivity reliability without requiring the user to carry separate devices
Solution Approach 2:
The emergency alert device is designed with multi-functionality by incorporating both radio and Bluetooth transmission capabilities. This universal design allows the device to adapt to different usage scenarios and environments - functioning as a home-based alarm system when stationary and as a mobile personal alarm when外出 - ensuring reliable emergency communication regardless of the user's location or available infrastructure
2Duration of action of moving object
If frequent recharging is required to maintain battery power, then the device can remain functional, but user convenience deteriorates due to the need for regular maintenance
Solution Approach 1:
The patent implements a high-capacity battery designed to provide power for extended periods (one year or more) before requiring recharging. This preliminary action of equipping the device with sufficient energy capacity from the outset eliminates the need for frequent user intervention for recharging, allowing the device to remain functional throughout long periods without maintenance, thereby dramatically improving ease of operation for elderly or vulnerable users
