Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multiple communication schemes using the same frequency band, such as the 2.4 GHz band, can lead to monopolization, causing degradation in the quality of service and interference among electronic devices.
Innovation Solution
An electronic device adjusts antenna usage time to manage simultaneous communication with multiple devices using different communication schemes, optimizing performance and reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple communication schemes simultaneously use the same frequency band, then communication versatility is improved, but service quality and reliability deteriorate due to monopolization and interference
Solution Approach 1:
The patent implements periodic time-division multiplexing where the antenna is allocated to different communication schemes in alternating time slots. The first communication scheme uses the antenna during first time slots, while the second communication scheme uses it during second time slots, creating a periodic pattern that prevents monopolization and ensures both schemes can operate reliably
Solution Approach 2:
The patent dynamically adjusts the antenna connection state by switching between connecting to the first communication scheme and disconnecting to allow the second communication scheme to operate. This dynamic switching enables the system to adaptively manage resource allocation based on communication scheme requirements, preventing interference while maintaining versatility
2Reliability
If antenna is continuously connected for communication, then communication performance is maintained, but power consumption increases
Solution Approach 1:
The communication module periodically switches the antenna connection state between connected and disconnected states according to time-division multiplexing schedules. The antenna is connected only during time slots allocated to its corresponding communication scheme and disconnected during other time slots, reducing power consumption while maintaining communication performance through periodic activation
Solution Approach 2:
The system autonomously manages antenna resource allocation by automatically switching connection states based on communication scheme requirements. The communication module itself controls the antenna switching without requiring continuous external intervention, enabling efficient self-managed power and resource optimization
