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

VSEngineering 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

Engineering Contradiction:
Improvedata transmission reliabilityVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If re-transmission of data packets is performed to correct errors, then data accuracy is improved, but transmission time increases

Engineering Contradiction:
Improvedata accuracyVSAvoidtransmission time
Core Design Contradiction:
ReliabilityVSLoss of time

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.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If the receiver is kept active continuously to receive and correct errors, then error detection capability is improved, but power consumption increases

Engineering Contradiction:
Improveerror detection capabilityVSAvoidreceiver power consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

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.

Inventive Principle:
Principle #19Periodic action

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.

Inventive Principle:
Principle #2Taking out (Extraction)
