Calling Apparatus Signal Transmission Stop Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing locator systems continue to transmit a calling signal unnecessarily after it has been received by the locator, potentially interrupting communication with other apparatuses and delaying the reception of a response signal.
Innovation Solution
A radio communication system where the calling apparatus stops the transmission of the calling signal once a response is received or a predetermined time period elapses, using timers and synchronization protocols to manage communication and power states in the locator and calling apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the calling apparatus continues to transmit a calling signal for a certain time period, then the locator can reliably receive the calling signal, but the transmission becomes useless after the locator has already received it, interrupting other communications and delaying response signal reception
Solution Approach 1:
The calling apparatus monitors the reception status of the calling signal by the locator and provides feedback information. Based on this feedback indicating successful reception, the calling apparatus stops transmitting the calling signal, thereby eliminating useless continuous transmission while ensuring reliable initial reception.
2Reliability
If the calling apparatus continues to transmit a calling signal, then the locator can be ensured to receive it, but the reception of the response signal from the locator is delayed
Solution Approach 1:
The system uses feedback information from the locator indicating successful calling signal reception. Upon receiving this feedback, the calling apparatus stops transmitting the calling signal and can immediately begin receiving the response signal, thereby reducing the delay in response signal reception while maintaining reliable calling signal delivery.
3Reliability
If the calling apparatus continuously transmits the calling signal, then the locator can reliably detect it, but communication with other apparatuses is interrupted
Solution Approach 1:
The calling apparatus receives feedback information from the locator confirming successful reception of the calling signal. Based on this feedback, the calling apparatus stops further transmission of the calling signal, thereby eliminating continuous transmission that would interfere with other communications while ensuring the locator reliably detected the signal.

AI summary
Disclosed is a radio communication apparatus capable of stopping useless transmission of a calling signal to a locator. A calling apparatus transmits, using a near field radio communication apparatus, a calling signal to a locator attached to an item and outputting a notification sound, the calling signal being used for calling the locator. The calling apparatus periodically stands by for reception of a response signal from the locator using one slot when performing consecutive transmission of the calling signal to the locator using a plurality of slots. The calling apparatus stops the consecutive transmission of the calling signal by being triggered upon reception of the response signal from the locator.
