Hearing Instrument Wireless Network Error Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hearing instruments face challenges in minimizing power consumption and transmission time due to the need for error correction in wireless communication, as existing methods require significant power and time for re-transmitting data packets, which is not feasible with limited power supplies like ZnO2 batteries.
Innovation Solution
A data package is divided into multiple packages and a redundant package is created to enable error detection and correction, allowing the receiver to activate only when errors are detected, reducing unnecessary power consumption and transmission time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If error correction schemes are implemented in wireless communication for hearing instruments, then data transmission reliability is improved, but power consumption and transmission time increase significantly
Solution Approach 1:
The original data package is divided into multiple segmented packages (first data package, second data package, etc.). Instead of transmitting one large package with full error correction, the data is split into smaller segments that can be transmitted more efficiently. The receiver reconstructs the original data by combining these segments, reducing the overall power consumption while maintaining reliability.
Solution Approach 2:
The invention changes the parameter of data package structure by introducing a reconstructed data package formed from multiple smaller data packages. This parameter change allows the system to transmit data in a more power-efficient manner while still achieving error correction through the reconstruction process at the receiver end.
2Reliability
If re-transmission of data packets is performed to correct errors, then data accuracy is improved, but transmission time increases
Solution Approach 1:
The invention performs preliminary action by creating multiple segmented data packages in advance, each containing portions of the original data. These segments are transmitted simultaneously or in sequence without requiring re-transmission, as the receiver can reconstruct the complete data from the segments. This eliminates the time loss associated with traditional re-transmission error correction methods.
3Reliability
If the receiver is kept active continuously to receive and correct errors, then error detection capability is improved, but power consumption increases
Solution Approach 1:
The receiver operates using periodic action by activating only during specific time slots when data packages are transmitted. Instead of remaining continuously active, the receiver wakes up periodically to receive and process data segments, then returns to a low-power state. This periodic operation maintains error detection capability while significantly reducing overall power consumption.
Solution Approach 2:
The invention extracts only the essential reception function at specific moments, activating the receiver solely when data packages need to be received. By taking out the continuous operation requirement and replacing it with discrete, event-driven activation, the system maintains error detection capability while minimizing power consumption during non-reception periods.
