Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wireless data connection is established between a mobile computer device and a domestic appliance for remote control, then the flexibility and effectiveness of data communication is improved, but the device complexity and security risks increase
Solution Approach 1:
The patent implements dynamic connection states that automatically transition between first connection state (full remote control access) and second connection state (local control only) based on the door opening/closing events. This dynamic adaptation resolves the contradiction by providing flexible remote control when needed while automatically reducing complexity and security risks when the appliance is locally accessible.
Solution Approach 2:
The system uses door opening/closing detection as feedback triggers to automatically switch connection states. When the door is opened, the system detects this event and transitions from first connection state to second connection state, providing automatic feedback-based adaptation that balances flexibility with security and complexity management.
2Ease of operation
If remote control is enabled via wireless connection, then the usability of the domestic appliance is improved, but the safety risks increase due to unauthorized access
Solution Approach 1:
The connection state dynamically changes based on door status. When the door is closed, the system allows first connection state for remote control usability. When the door is opened, it automatically transitions to second connection state, blocking remote control access and preventing unauthorized local access, thus dynamically managing safety risks.
Solution Approach 2:
The system preemptively blocks remote control access by transitioning to the second connection state when the door is opened, before any potential unauthorized access can occur. This preliminary anti-action prevents security issues rather than reacting to them after they occur.
3Productivity
If the mobile computer device can control the domestic appliance from any location, then the effectiveness of operation is improved, but the loss of time for connection establishment increases
Solution Approach 1:
The wireless connection and first connection state are established in advance before the user needs to remotely operate the appliance. The system maintains readiness for remote control when the door is closed, so when the user wants to operate the appliance remotely, the connection is already in place, eliminating connection establishment time and improving operational effectiveness.
