Wireless Display Control Signal Sharing via Intermediary Mediation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless display systems, control signals often fail to reach both the receiving and transmitting modules due to interference or timing differences when transmitted from a remote control device, leading to synchronization issues between the modules.
Innovation Solution
The system employs a method where the receiving module and transmitting module share control signals received from a remote control device, with each module equipped with units for determining and transmitting control signals, and utilizing different communication frequencies (IR and Bluetooth) to minimize interference and ensure simultaneous operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If control signals are transmitted from a remote control device to both receiving and transmitting modules, then both modules can be controlled, but control signals may fail to reach at least one module due to interference or timing differences
Solution Approach 1:
The patent introduces an intermediary mechanism where one module (receiving or transmitting) that successfully receives the control signal acts as a mediator to forward the signal to the other module. This intermediary approach ensures that control signals are reliably delivered to both modules even when direct transmission to one module fails due to interference or timing issues.
Solution Approach 2:
The patent implements a copying mechanism where the control signal received by one module is replicated and transmitted to the other module. This ensures that both modules receive identical control signals simultaneously, eliminating timing differences and interference issues that would otherwise cause one module to miss the signal.
2Adaptability or versatility
If the receiving module and transmitting module are disposed separately, then installation flexibility is improved, but control signal transmission to both modules becomes unreliable due to interference
Solution Approach 1:
By disposing the modules separately for installation flexibility, the patent uses the intermediary approach where one module forwards control signals to the other. This maintains the benefit of separate installation while compensating for the reliability issue through the mediator mechanism.
Solution Approach 2:
The copying mechanism ensures that control signals are replicated and transmitted to both separately disposed modules, maintaining reliable control delivery despite the physical separation that enables installation flexibility.
3Productivity
If control signals are transmitted to both modules simultaneously, then both modules can operate, but timing differences occur between when the signal reaches each module
Solution Approach 1:
The copying mechanism transmits the control signal to both modules at the same time, ensuring they receive and execute the signal simultaneously. This eliminates timing differences and synchronization issues while maintaining operational efficiency of the distributed system.
Solution Approach 2:
The intermediary approach where one module forwards signals to the other can also synchronize timing by ensuring the signal is relayed immediately upon receipt, eliminating delays and timing mismatches between modules.
