Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hearing aid technologies face challenges in efficiently receiving sound signals from smart devices without increasing power consumption, leading to poor endurance and convenience issues for users with hearing impairments.
Innovation Solution
A wireless communication apparatus for hearing aids that connects directly to a portable terminal, utilizing a first wireless communication module for communication with the hearing aid and obtaining electric energy, while also using a second or third wireless communication module for communication with external smart devices, employing low power wireless transmission techniques to reduce power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a Bluetooth communication module is added to the hearing aid for wireless communication with smart products, then the hearing aid can directly receive audio signals from smart products, but the power consumption increases significantly affecting endurance capability
Solution Approach 1:
The patent introduces a wireless communication apparatus as an intermediary device between the smart product and the hearing aid. This apparatus includes a first wireless communication module that communicates with the hearing aid and a second wireless communication module that communicates with the smart product. By using this intermediate device, the hearing aid avoids direct high-power Bluetooth communication with smart products, thereby reducing its power consumption while maintaining the ability to receive audio signals wirelessly.
2Reliability
If a repeater is added between the hearing aid and the smart product to improve signal transmission, then the wireless communication quality improves, but the portability deteriorates as the patient needs to carry the repeater
Solution Approach 1:
The wireless communication apparatus is designed to be integrated with or replaceable as part of the hearing aid system, serving multiple functions: it acts as a wireless communication interface with smart products, a signal amplifier, and a power management unit. By combining these functions into a single integrated apparatus that can be worn on the body, the system maintains reliable wireless communication without requiring a separate portable repeater device.
3Ease of operation
If the hearing aid directly receives sound played by a mobile phone, then the wireless communication convenience improves, but the sound signal quality deteriorates due to multiple conversions
Solution Approach 1:
The wireless communication apparatus serves as an intermediary that receives audio signals from smart products via its second wireless communication module and transmits them to the hearing aid via its first wireless communication module. This intermediate transmission path allows for better signal management and processing, reducing the number of conversion stages that the hearing aid itself must perform, thereby improving sound signal quality while maintaining wireless convenience.
