Multisensory Alarm Controller for Hearing Impaired Users
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for alerting individuals with hearing impairments are limited in their ability to provide comprehensive and reliable alerts, often requiring replacement of existing hardware and lacking in multisensory notification capabilities.
Innovation Solution
A comprehensive alarm monitoring system comprising a controller, sensors, and signaling devices that use wireless communication, including radio frequency, Bluetooth, and Wi-Fi, to provide alerts through flashing lights, vibrations, and audible alarms, with the ability to integrate with various sensors and power sources, and optionally connect to the internet for increased reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing hardware is replaced to improve alert reliability, then the reliability of alerts is improved, but the device complexity and installation difficulty increase
Solution Approach 1:
The system is designed to work with multiple types of sensors (doorbell sensors, fire alarm sensors, baby monitor sensors, etc.) and multiple signaling devices (flashers, bed shakers, pagers) through a universal controller that supports various communication protocols including wireless RF, Bluetooth, and Wi-Fi, eliminating the need to replace existing specialized hardware
Solution Approach 2:
A wireless communication intermediary layer (RF, Bluetooth, Wi-Fi) is introduced between the controller and sensors/signaling devices, allowing the system to integrate with existing hardware without direct physical replacement while maintaining reliable communication for alert transmission
2Ease of manufacture
If simple alert mechanisms are used to reduce device complexity, then the ease of manufacture is improved, but the versatility of alerting capabilities deteriorates
Solution Approach 1:
The system is segmented into independent modular components: a controller unit, multiple sensor types, and multiple signaling device types. Each component can be manufactured separately and simply, yet the combination provides versatile multisensory alerting capabilities through wireless coordination
Solution Approach 2:
The controller is designed with universal functionality to manage multiple sensor types and multiple signaling device types simultaneously, providing diverse alerting capabilities (visual, tactile, audible) while maintaining relatively simple individual component manufacturing
3Ease of operation
If wireless communication is implemented to improve system adaptability, then the ease of operation is improved, but the use of energy increases
Solution Approach 1:
The wireless communication system uses periodic transmission and sleep cycles where the controller and sensors communicate at intervals rather than continuously. The system can enter low-power states between alert events, reducing overall energy consumption while maintaining ease of wireless operation and installation
Data Source
AI summary
The alarm monitoring system provides various alerts of events that are not readily discernable to those with hearing difficulties. The system generates visual, vibratory, and high decibel alerts separately or in combination to alert the user to a wide variety of events for those with multisensory impairments.
