Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for synchronizing radio frequency (RF) module activities in multi-technology mobile devices are limited, leading to interference, high power consumption, and maintenance challenges, as they are not scalable and require complex inter-technology dependencies or power-intensive jammer detection.
Innovation Solution
A method and apparatus using an RF activity bulletin board to mediate notifications among RF modules, allowing each module to subscribe to specific notifications based on criteria, reducing interference and power consumption by decoupling direct inter-technology interactions and implementing a scalable architecture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If RF modules operate independently without synchronization, then each module can function autonomously, but interference between modules increases and receiver performance deteriorates
Solution Approach 1:
The patent introduces an RF activity bulletin board as an intermediary component that receives notifications from transmitter RF modules and relays them to receiver RF modules. This mediator enables coordinated operation without direct module-to-module interference, allowing autonomous function while preventing harmful interactions through centralized notification management
2Productivity
If multiple RF modules transmit simultaneously, then communication throughput increases, but peak power demand increases causing battery load issues and transmission failures
Solution Approach 1:
The bulletin board implements a feedback mechanism where transmitter modules notify the board of their transmission activities, which then relays this information to other modules. This feedback loop enables receivers to prepare for incoming signals and transmitters to coordinate their operations, allowing higher throughput while managing peak power demands through informed scheduling
3Reliability
If previous synchronization solutions are implemented for two closely related wireless technologies, then coexistence between those specific technologies is achieved, but the solution is not scalable to all wireless technologies and requires complex linkages
Solution Approach 1:
The patent creates a universal RF activity bulletin board that can handle notifications from any RF module regardless of the specific wireless technology it uses. This single multi-functional component replaces multiple technology-specific synchronization mechanisms, achieving reliable coexistence across all wireless technologies while maintaining scalability and simplicity
4Reliability
If jammer detectors are used to detect internal jammers, then transmission reliability improves, but power consumption increases
Solution Approach 1:
Instead of using power-intensive jammer detectors to identify interference after it occurs, the bulletin board performs preliminary action by notifying receiver modules of upcoming transmissions in advance. This allows receivers to prepare their reception parameters proactively, achieving reliable transmission without the need for continuous jammer detection and significantly reducing power consumption
