Bluetooth Transmitter Feedback Control for Broadcasting Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Bluetooth transmitters cannot determine if data packages are successfully received by receivers, leading to unpredictable data package broadcasting quality and a lack of control over re-broadcasting processes.
Innovation Solution
Implementing a method where the Bluetooth transmitter detects receivers within its range, broadcasts data packages, and receives acknowledgement or non-acknowledgement packages to determine the success of the transmission, allowing for re-broadcasting until all receivers confirm receipt.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the conventional blue-tooth transmitter re-broadcasts data packages multiple times with engineer-set parameters, then the broadcasting coverage is improved, but the broadcasting quality control deteriorates and success rate remains unpredictable
Solution Approach 1:
The patent implements a feedback mechanism where blue-tooth receivers send acknowledgement packages to the transmitter after receiving data packages. The transmitter monitors these acknowledgements and automatically decides whether to re-broadcast based on the feedback received, eliminating the need for engineer-configured re-broadcasting parameters and achieving reliable broadcasting quality control.
2Reliability
If the blue-tooth transmitter broadcasts data packages without receiving feedback, then the broadcasting process is simple, but the broadcasting quality and success rate deteriorate
Solution Approach 1:
The patent introduces a feedback mechanism where receivers automatically send acknowledgement packages to the transmitter. This feedback enables the transmitter to determine whether data packages were successfully received and to make automatic re-broadcasting decisions, significantly improving broadcasting reliability while maintaining operational simplicity through automated control.
Solution Approach 2:
The system implements self-service broadcasting where the transmitter automatically monitors acknowledgement feedback from receivers and autonomously decides whether to re-broadcast data packages. This eliminates the need for external engineer intervention or complex manual control, achieving both high reliability and ease of operation through automated self-adjustment.
3Adaptability or versatility
If the blue-tooth transmitter uses fixed re-broadcasting parameters set by engineers, then the system complexity is reduced, but the adaptability to different broadcasting scenarios deteriorates
Solution Approach 1:
The patent transforms the static, engineer-configured re-broadcasting system into a dynamic adaptive system. The transmitter continuously monitors acknowledgement feedback from receivers and automatically adjusts its broadcasting strategy in real-time based on the actual reception status, enabling adaptation to different broadcasting scenarios without requiring complex preconfiguration or manual intervention.
