Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple communication modules are integrated into a single device, then the communication capability and versatility are improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple communication modules (first communication module and second communication module) into a single integrated communication device that connects to one USB port. This merging approach allows the device to provide multiple communication standards (e.g., Wi-Fi, Bluetooth, cellular) without requiring multiple separate connectors, thus improving versatility while managing complexity through integration.
Solution Approach 2:
The integrated communication device is designed to support multiple communication functions through a single universal interface. The device can switch between different communication modules based on operational requirements, enabling one USB port to serve multiple purposes (data transmission, wireless communication, power supply), thereby enhancing adaptability without proportionally increasing device complexity.
2Adaptability or versatility
If multiple connection interfaces are provided for simultaneous connections to multiple peripheral devices, then the connectivity and versatility are improved, but the area required in the mobile terminal increases
Solution Approach 1:
The patent merges multiple connection interfaces into a single USB port that can accommodate different peripheral devices through an integrated communication device. Instead of providing separate physical interfaces for each communication standard, the system uses one universal interface that can connect to various devices by switching between communication modules, thus maintaining connectivity while reducing the area required in the mobile terminal.
Solution Approach 2:
The single USB port is designed as a universal interface that can support multiple communication functions and peripheral devices. The integrated communication device enables this port to perform multiple roles (Wi-Fi communication, Bluetooth, data transfer, power supply) by dynamically switching between different communication modules, thereby achieving high connectivity without requiring multiple dedicated interfaces.
3Reliability
If all communication modules are kept active to ensure availability, then the service availability is improved, but the power consumption increases
Solution Approach 1:
The patent implements dynamic control of communication module activation based on operational needs. The device controller can selectively activate or deactivate specific communication modules depending on the current communication task, ensuring that only necessary modules remain active. This dynamic approach maintains service availability for required functions while minimizing power consumption by keeping unnecessary modules in a low-power or inactive state.
Solution Approach 2:
The system changes the operational state parameters of communication modules based on demand. By monitoring communication requirements, the device controller adjusts the power state of each module (active, standby, or off), thereby optimizing the balance between service availability and power consumption. This parameter-based control ensures high availability for active functions while significantly reducing overall power usage.
