Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote control is implemented through external devices using radio signals, then ease of operation is improved, but device complexity increases due to need for signal transmission, key code verification, and application activation management
Solution Approach 1:
The patent uses radio signals as an intermediary medium to transmit remote control information between external devices and the digital device. The signal includes key codes that act as mediators for identifying and activating specific remote applications, enabling convenient remote control without direct device interaction
Solution Approach 2:
The digital device is designed to support multiple wireless communication protocols (Wi-Fi and Bluetooth) within a single system, allowing it to receive and process remote control signals from various external devices using different protocols. This multi-functionality enables universal remote control capability while managing complexity through protocol selection based on signal type
2Productivity
If automatic application activation is implemented based on received signals, then productivity is improved by eliminating manual activation steps, but reliability decreases due to risk of unintended application execution
Solution Approach 1:
The system performs preliminary verification by extracting and verifying key codes from received radio signals before activating remote applications. The key code matching process is executed in advance of application activation to ensure the correct application is selected, preventing unintended execution while maintaining automatic activation
Solution Approach 2:
The system uses key code verification as a feedback mechanism to confirm that the received signal corresponds to the intended remote application before activation. This feedback loop ensures reliability by validating the signal content matches the target application, preventing erroneous activation while maintaining automatic operation
