One-Way Communication Signal Strength Feedback for Power Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Blood pressure monitors with one-way communication transmission functions face issues with data security and control, as they cannot transmit control data or refer to the data reception state of the portable information terminal, leading to potential data leakage and increased power consumption.
Innovation Solution
A data receiving apparatus that calculates the reception signal strength of one-way communication packets and compares it with a threshold value, generating assistance information to help users adjust the transmission power, thereby enhancing security and reducing data leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by stationary object
If one-way communication is used for data transmission, then power consumption is reduced and device complexity is lowered, but control capability is lost and data security is compromised
Solution Approach 1:
The system implements feedback by having the receiving apparatus measure reception signal strength and generate assistance information that is transmitted back to the transmitting apparatus. This feedback loop enables the transmitter to adjust its transmission power based on actual reception conditions, achieving both power efficiency and security without requiring full two-way communication capability.
Solution Approach 2:
The transmitting apparatus dynamically changes the transmission power parameter based on assistance information from the receiver. By adjusting this key parameter, the system can optimize power consumption while maintaining data security - lowering power when signal strength is sufficient and increasing it only when necessary for reliable reception.
2Reliability
If transmission power is increased to ensure data reception, then data reception reliability is improved, but data leakage risk increases
Solution Approach 1:
The system makes transmission power dynamic rather than static. The transmitting apparatus continuously adjusts transmission power based on real-time feedback about reception signal strength. This dynamic adjustment ensures reliable data reception when needed while minimizing transmission power (and thus data leakage risk) during normal operation.
Solution Approach 2:
The key transmission power parameter is changed dynamically based on reception conditions. The system transitions from fixed high-power transmission (which creates security risks) to adaptive power levels that match actual reception needs, thereby reducing data leakage risk while maintaining reliability.
3Ease of operation
If assistance information is provided to users, then transmission power control is improved, but device complexity increases
Solution Approach 1:
The system implements self-service by automatically generating and transmitting assistance information without requiring complex user intervention. The receiving apparatus autonomously measures signal strength, determines appropriate power adjustment recommendations, and communicates these to the transmitter, simplifying the overall control mechanism while improving ease of operation.
