Tire Condition Detection Protocol Switching for Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tire condition detecting devices face increased power consumption when transmitting data signals using multiple protocols, regardless of whether an anomaly is present, as they often transmit data signals as frequently and with the same power regardless of the protocol type.
Innovation Solution
A tire condition detecting device with a controlling section that designates one protocol as primary and another as secondary, adjusting transmission frequency and power based on detected anomalies, using the secondary protocol only when an anomaly is detected to reduce power consumption and ensure data signal reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If data signals are transmitted using multiple types of protocols, then compatibility with different receivers is improved, but power consumption increases
Solution Approach 1:
The patent applies dynamics by making the transmission protocol selection variable rather than fixed. The controlling section dynamically switches between single-protocol mode (normal operation) and multi-protocol mode (anomaly detection) based on real-time tire condition monitoring, optimizing power consumption while maintaining receiver compatibility when needed
Solution Approach 2:
The patent changes the transmission parameters (protocol type, transmission frequency, power level) based on the detected tire condition. When anomalies are detected, the system transitions from using a single protocol at standard power/frequency to using multiple protocols with adjusted transmission parameters, ensuring receiver compatibility only when necessary
2Reliability
If data signals are transmitted more frequently using multiple protocols, then data reception reliability is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic action by transmitting data signals at different frequencies based on operational mode. During normal operation, transmissions occur at standard intervals using a single protocol. When anomalies are detected, the system increases transmission frequency and uses multiple protocols, maintaining reliability only when necessary to conserve power
3Stability of the object's composition
If the same transmission power is used for all protocols, then transmission consistency is maintained, but power consumption increases
Solution Approach 1:
The patent applies local quality by assigning different transmission power levels to different protocols based on their specific requirements and the operational context. The controlling section adjusts power levels individually for each protocol being transmitted, rather than using a uniform power level, optimizing energy efficiency while maintaining adequate signal quality for each protocol type

AI summary
A tire condition detecting device includes a controlling section that determines whether there is an anomaly in the tire based on the condition of the tire detected by the condition detecting section. A protocol that is designated by a trigger device is defined as a first protocol, and protocols that are not designated by the trigger device are defined as second protocols. When determining that there is no anomaly in the tire, the controlling section causes the transmission section to transmit only the data signals using the first protocol. When determining that there is an anomaly in the tire, the controlling section causes the transmission section to transmit the data signals using the second protocols in addition to the data signals using the first protocol.
