Ear-Level Device Audible Alarm Volume Dynamics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Small, expensive electronic devices like ear-level devices are prone to being misplaced and difficult to find once lost, as existing technologies lack effective methods for locating them.
Innovation Solution
A method is implemented where an ear-level device, equipped with a processor, microphone, and speaker, communicates with a companion device to broadcast an audible location alarm, increasing in volume over time, to help the user locate the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If an ear-level device is made small and lightweight for comfortable wear, then it becomes easy to misplace and difficult to find
Solution Approach 1:
The system performs preliminary action by establishing communication between the ear-level device and companion device before loss occurs. The companion device stores location information and can immediately trigger an audible alarm when loss is detected, eliminating the need for post-loss detection methods
Solution Approach 2:
The companion device serves as an intermediary that bridges the ear-level device and the user. It receives communication from the ear-level device, processes location data, and generates audible alarms to alert the user of the device's location, solving the detection problem without modifying the ear-level device itself
2Difficulty of detecting and measuring
If the audible location alarm volume is increased to enhance detectability, then it may cause loud noise warnings and user discomfort
Solution Approach 1:
The alarm volume is made dynamic rather than static. The system adjusts the alarm volume based on real-time conditions, starting at a moderate level and increasing only if the device remains undetected after a predetermined time period. This dynamic adjustment ensures detectability while minimizing noise warnings and user discomfort
Solution Approach 2:
The system implements periodic action by using time-based thresholds to control alarm behavior. The alarm follows a predetermined time schedule: initial alarm period at moderate volume, followed by a time delay, then increased volume if detection fails. This periodic approach balances detectability with user comfort
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The method allows users to easily find misplaced ear-level devices by broadcasting a loud audible signal, enhancing the likelihood of detection and retrieval.
Implementation Method 1
an audible location alarm signal is transmitted to the ear-level device, thereby providing instruction to the ear-level device to broadcast an audible location alarm through the speaker of the ear level device
Data Source
AI summary
An audible location alarm is generated from an ear-level device of a type comprising a memory, a microphone and a speaker, each coupled to a processor. Communication is established between the ear-level device and a companion device, the companion device having an interface, a display associated with the user interface, and an audible location alarm program stored therein. The audible location alarm program is initiated. An audible location alarm signal is transmitted to the ear-level device, thereby providing instruction to the ear-level device to broadcast an audible location alarm through the speaker of the ear level device until detection of an end event.
