Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with shared antennas for multiple communication modules face reduced data throughput and temporary disconnections due to frequency and usage conflicts, particularly as the number of connected Bluetooth devices increases, leading to signal loss and reduced performance.
Innovation Solution
An electronic device with multiple antennas and a processor that determines occupancy information to dynamically allocate antennas for different communication modules based on usage, allowing for simultaneous or sequential use of antennas and switching between them to prevent signal loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multiple communication modules share a single antenna through time-division scheme, then device complexity is reduced, but data throughput is reduced and connection stability deteriorates
Solution Approach 1:
The patent implements dynamic antenna allocation where the processor monitors occupancy information of antennas in real-time and dynamically switches which communication module uses which antenna based on current usage conditions. This resolves the contradiction by making the system adaptable rather than static, allowing full antenna resources to be dedicated to whichever module needs them most at any given moment, thereby maintaining high data throughput while using fewer physical antennas.
Solution Approach 2:
The processor performs preliminary assessment of occupancy information before allocating antenna resources. By evaluating the usage frequency and data throughput requirements of different communication modules in advance, the system can proactively assign antennas to prevent potential conflicts before they occur, ensuring optimal data throughput is maintained while managing limited antenna resources efficiently.
2Device complexity
If multiple communication modules share a single antenna through time-division scheme, then device complexity is reduced, but connection stability deteriorates
Solution Approach 1:
The system dynamically monitors occupancy information including usage frequency and data throughput of each communication module, and adaptively switches antenna allocation in real-time. This dynamic approach prevents connection instability by ensuring that when one module requires heavy antenna usage, other modules can temporarily use different antennas or wait, avoiding conflicts that would cause disconnections.
Solution Approach 2:
The processor continuously monitors occupancy information as feedback about antenna usage conditions. Based on this feedback, the system adjusts antenna allocation decisions to maintain connection stability. When occupancy information indicates high usage by one module, the system responds by allocating appropriate antenna resources to prevent disconnection of other modules.
3Productivity
If antenna resources are allocated to one communication module, then that module's performance is improved, but other modules experience signal loss
Solution Approach 1:
The patent segments antenna resources dynamically among multiple communication modules based on their instantaneous needs. Rather than permanently assigning specific antennas to specific modules, the processor divides antenna usage into time-based segments, allowing each module to receive dedicated antenna access when needed. This segmentation prevents any single module from monopolizing antenna resources, thereby avoiding signal loss in other modules while maintaining high throughput for the active module.
Solution Approach 2:
The system changes the allocation parameters of antenna resources based on occupancy information such as usage frequency and data throughput requirements. By adjusting these parameters dynamically, the system optimizes performance for the current primary communication module while ensuring other modules retain sufficient antenna access to prevent signal loss, resolving the contradiction between one module's high throughput and others' reliability.
