Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mobile radio terminal uses a single module for receiving multimedia services (FLO or MBMS), then the device complexity is reduced, but the reception reliability deteriorates due to dead spots and limited coverage areas
Solution Approach 1:
The patent combines multiple multimedia service modules (FLO module and MBMS module) into a single mobile radio terminal. The terminal includes both modules simultaneously and uses a switching device to select between them based on signal strength, thereby improving reception reliability without requiring the user to manually switch between services
Solution Approach 2:
The mobile radio terminal is designed with multi-functionality by incorporating both FLO and MBMS modules, allowing it to receive multimedia services through multiple standards. This universal capability ensures that the terminal can operate reliably across different coverage areas regardless of which service is available
2Adaptability or versatility
If the terminal manually switches between multimedia services, then the adaptability to different coverage areas is improved, but the ease of operation deteriorates due to cumbersome and time-consuming switching processes
Solution Approach 1:
The terminal performs self-service by automatically monitoring signal strength and triggering module switching without user intervention. The triggering means continuously evaluates the received signal strength indicator (RSSI) of the current module and automatically switches to the other module when signal quality deteriorates, eliminating the need for manual user actions
Solution Approach 2:
The system uses feedback from signal strength monitoring to control the switching behavior. The triggering means receives feedback about the current module's signal quality and uses this information to automatically initiate switching when necessary, creating a closed-loop control system that adapts to changing reception conditions
3Loss of time
If the terminal switches between modules manually, then the loss of time during service interruption is reduced, but the productivity deteriorates due to interruptions in multimedia service reception
Solution Approach 1:
The system performs preliminary actions by continuously monitoring signal strength and proactively switching modules before complete service interruption occurs. The triggering means detects signal degradation early and initiates the switching process in advance, ensuring seamless transition and preventing interruptions to the multimedia service
4Reliability
If the terminal uses multiple modules for multimedia services, then the reliability of reception is improved, but the use of energy deteriorates due to power consumption of multiple modules
Solution Approach 1:
The terminal dynamically adjusts its operation by activating only the necessary module at any given time. The switching device, controlled by signal strength monitoring, ensures that only one module is actively receiving and processing multimedia services at a time, thereby minimizing energy consumption while maintaining reception reliability through automatic switching capability
