Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless communication is performed between binaural hearing devices at a constant high packet transmission rate, then signaling quality and connectivity reliability are improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic adjustment of mirror service properties including packet transmission rate and packet format based on real-time monitoring of hearing device operating parameters. The system transitions from static constant-rate transmission to adaptive dynamic transmission, adjusting the packet transmission rate according to actual connectivity needs and operating conditions to optimize the balance between reliability and power consumption
Solution Approach 2:
The system changes transmission parameters (packet transmission rate, packet format) based on monitored operating parameters. When operating parameters indicate stable conditions, the system reduces packet transmission rate to save power; when parameters indicate potential connectivity issues, the system increases transmission rate to maintain reliability, thus dynamically optimizing the trade-off
2Use of energy by moving object
If packet transmission rate is reduced to save power, then power consumption decreases, but signaling quality and connectivity reliability deteriorate
Solution Approach 1:
The system continuously monitors hearing device operating parameters and uses this feedback to adjust mirror service properties. The feedback loop ensures that packet transmission rate is reduced only when operating conditions permit, maintaining signaling quality while optimizing power consumption. The system detects changes in operating parameters and responds by adjusting transmission rate accordingly
Solution Approach 2:
The patent implements dynamic adjustment of mirror service properties including packet transmission rate and packet format based on real-time monitoring of hearing device operating parameters. The system transitions from static constant-rate transmission to adaptive dynamic transmission, adjusting the packet transmission rate according to actual connectivity needs and operating conditions to optimize the balance between reliability and power consumption
