Tire Condition Detection Device Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tire condition detection devices have limited battery life due to maintaining a receiving section in a standby state for external signal reception, which is only necessary during specific inspections or updates, leading to unnecessary power consumption.
Innovation Solution
A tire condition detection device with a control section that switches between responsive and non-responsive states, reducing power consumption by minimizing reception responses and standby power usage, especially when receiving signals from unintended external devices or in non-inspection scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the receiving section is always maintained in the standby state to receive external signals, then the device can respond to inspection and software update commands, but the battery life is shortened due to continuous power consumption
Solution Approach 1:
The receiving section dynamically switches between standby state and non-standby state based on operational needs. The control section activates the receiving section to standby state when external devices need to communicate (inspection, software update, ID registration) and deactivates it during normal operation, making the system adaptive rather than static.
Solution Approach 2:
The receiving section operates in periodic cycles rather than continuously. It alternates between active standby periods when external communication is needed and inactive periods during normal tire condition monitoring, reducing overall power consumption while maintaining necessary functionality.
2Adaptability or versatility
If the receiving section is kept in standby state for limited situations, then external devices can transmit information, but power is consumed unnecessarily during normal operation
Solution Approach 1:
The system dynamically adjusts the receiving section's operational state based on whether external communication is needed. During normal tire monitoring, the receiving section is deactivated to save power. When inspection, software updates, or ID registration are required, the control section activates it to standby state, optimizing the balance between adaptability and energy consumption.
3Reliability
If the receiving section remains in standby state, then the device can perform reception responses, but the battery is depleted faster
Solution Approach 1:
The receiving section operates periodically rather than continuously. It enters standby state only when external devices need to communicate and returns to non-standby state during normal operation. This periodic activation maintains signal reception readiness when needed while significantly reducing energy loss from continuous standby operation.
Solution Approach 2:
The system discards the standby state during periods when external communication is not needed and recovers battery power by avoiding unnecessary power consumption. The receiving section is selectively activated only when external signal reception is required, allowing the battery to conserve energy during extended periods of normal operation.

AI summary
A tire condition detection device includes a condition detecting section, a control section, a transmitting section, a receiving section, and battery, which is a power source for the tire condition detection device. When the receiving section continually receives information from an external device, a controller switches the state of the tire condition detection device from a responsive state to a non-responsive state. In the responsive state, the receiving section is maintained in a standby state, in which the receiving section is capable of receiving the information wirelessly transmitted from the external device, and a reception response is performed when the information is received. In the non-responsive state, the reception response by the receiving section is not performed regardless whether the receiving section is maintained in the standby state.
