Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hearing systems that utilize cartilage conduction face limitations in enhancing usability and efficiency, particularly in adapting to varying noise levels and user needs.
Innovation Solution
A hearing system comprising a finger ring and a hearing device main body, where the finger ring includes a short-distance wireless communication portion, a vibration output portion, and a power source, and the hearing device main body includes a microphone, a voice signal output portion, and a power source, enabling cartilage conduction vibrations to be transmitted to the ear via the finger, with remote power control and self-holding timer functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the finger ring and hearing device main body are separated into independent units with separate power sources, then mobility and comfort are improved, but device complexity increases
Solution Approach 1:
The hearing system is divided into two independent units: a finger ring unit and a hearing device main body unit. Each unit has its own power source (first power source portion in the finger ring, second power source portion in the main body), allowing them to operate independently. This segmentation enables the user to wear only the lightweight finger ring for mobility while the main body can be carried separately, improving comfort and mobility without requiring a single bulky device.
2Ease of operation
If remote power control functionality is added to the finger ring, then ease of operation is improved, but device complexity increases
Solution Approach 1:
A wireless communication system acts as an intermediary between the finger ring and the hearing device main body. The finger ring includes a short-distance wireless communication portion that can transmit power control signals to the main body's second short-distance wireless communication portion. This allows the user to control the power state of the main body device remotely from the finger ring without direct physical interaction, improving ease of operation while distributing control logic across the wireless communication protocol rather than adding complex local control circuitry.
3Reliability
If cartilage conduction vibration is transmitted through the finger, then hearing effectiveness is improved, but the system requires precise contact positioning which increases difficulty of operation
Solution Approach 1:
The finger ring is designed to be worn on the user's finger in a natural position, and the vibration output portion is positioned to automatically contact the finger when the ring is properly worn. The elastic band structure of the finger ring ensures consistent contact pressure and positioning without requiring the user to manually adjust or precisely position the vibration element. The system serves itself by utilizing the natural anatomy and movement of the finger to maintain optimal contact for cartilage conduction transmission.

AI summary
The hearing system comprises a finger ring and a hearing device body. The finger ring includes: a first short-distance wireless communication portion; a vibration output portion disposed at a position that contacts a finger to convert a voice signal, which is received by the first short-distance wireless communication portion, into a cartilage conduction vibration and outputs it; and a first power source portion that supplies power to the first short-distance wireless communication portion and the vibration output portion. The talk device body includes: a second short-distance wireless communication portion that communicates with the first short-distance wireless communication portion; a microphone; a voice signal output portion that makes the second short-distance wireless communication portion output the voice signal according to a voice captured by the microphone; and a second power source portion that supplies power to the second short-distance wireless communication portion, the microphone, and the voice signal output portion.
