Hearing Aid LED Visual Identification System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hearing aids often rely on color dots that can be difficult for elderly users to distinguish between left and right ear models, and these markings are fixed during production, lacking functionality when not in use.
Innovation Solution
A method utilizing a light emitting device that provides distinct light signals for left and right ear hearing aids when turned on, with programmable duration and intensity, allowing for secure identification before placement and optional disablement after use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a color dot marking is used on the hearing aid, then the user can identify whether it is for the left or right ear, but the marking is difficult to spot for elderly users and cannot be changed after production
Solution Approach 1:
The patent applies the dynamics principle by replacing the static color dot marking with a dynamic light-emitting diode (LED) indicator that can be activated and deactivated. The LED provides active visual feedback when the hearing aid is powered on, making the left/right identification clearly visible to elderly users without requiring permanent production markings. This dynamic approach allows the identification system to adapt to different usage states (powered on/off) and provides enhanced visibility when needed.
Solution Approach 2:
The patent applies parameter changes by utilizing the electrical power state as a control parameter for the identification system. When power is supplied to the hearing aid, the LED indicator is activated to display the left/right identification. When power is removed, the indicator turns off. This parameter-based control allows the same physical component to provide identification information only when needed, improving visibility for elderly users during the critical identification moment while consuming minimal power otherwise.
2Reliability
If a permanent marking is applied during production, then the hearing aid is dedicated to left or right ear, but the marking is only visible when needed and consumes power continuously if always on
Solution Approach 1:
The patent applies periodic action by activating the LED identification indicator only during specific periods when the hearing aid is powered on and needs identification, rather than continuously. The indicator operates in cycles: on when power is supplied and identification is needed, off when power is removed. This periodic operation maintains reliable identification accuracy during use while dramatically reducing overall power consumption compared to continuous operation.
Solution Approach 2:
The patent applies the extraction principle by separating the identification function from the permanent production marking and extracting it into a独立的 power-controlled LED indicator system. This allows the identification function to be independently controlled and activated only when needed, rather than being permanently fixed and always visible. The extraction enables the system to provide reliable identification when required while avoiding continuous power consumption.
3Loss of time
If the light signal remains visible continuously after turning on, then the user has ample time to identify the hearing aid, but power is consumed unnecessarily after placement
Solution Approach 1:
The patent applies partial action by providing the light signal for a limited duration after power-on rather than continuously. The LED indicator operates long enough to allow users to identify the hearing aid's left/right designation, but then automatically turns off once placement is complete. This partial operation provides sufficient identification time for most users while avoiding the energy waste of continuous operation after the identification function is no longer needed.
Solution Approach 2:
The patent applies self-service by implementing an automatic timeout feature that turns off the LED identification indicator after a predetermined period without user interaction. The system monitors whether the hearing aid has been placed in the ear (indicated by lack of further button presses or activation), and automatically deactivates the light signal accordingly. This self-managing feature ensures adequate identification time while autonomously reducing power consumption once placement is confirmed.
