Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the remote controller automatically locks after a period of inactivity to prevent accidental operation, then security is improved, but user convenience deteriorates as the operator must unlock it before use
Solution Approach 1:
The system performs preliminary action by automatically unlocking the remote controller when it detects that the operator has approached the vehicle (via proximity sensing or key recognition). This eliminates the need for manual unlocking while maintaining security, as the controller remains locked for others but is automatically unlocked for the authorized user before they can use it.
2Reliability
If the security system activates all sensors to provide comprehensive protection, then security coverage is improved, but false alarm frequency increases
Solution Approach 1:
The system applies local quality by allowing different sensors to have different activation states - some sensors are activated while others are bypassed or disabled based on their location and function. This enables comprehensive security coverage in critical areas while reducing false alarms from sensors prone to malfunction or environmental interference.
Solution Approach 2:
The system implements dynamics by allowing real-time modification of sensor activation status. Users can dynamically enable or disable specific sensors based on current needs, such as disabling vibration sensors when parked on busy streets or enabling them when parked in secure locations, thus adapting security coverage to situational requirements.
3Loss of information
If the system provides detailed alarm information including sensor identification, then alarm source identification is improved, but system complexity increases
Solution Approach 1:
The system applies feedback by providing real-time alarm information to the user through the remote controller or in-vehicle display, including identification of which sensor was triggered. This detailed feedback enables quick identification of alarm sources without requiring complex user interpretation, as the system automatically processes and presents the information in an understandable format.
4Adaptability or versatility
If the remote controller is designed with multiple keys for comprehensive control, then functional capability is improved, but portability and comfort deteriorate
Solution Approach 1:
The system implements universality by designing a single remote controller that can control multiple vehicle functions (locking, unlocking, trunk release, panic alarm, remote start) and potentially multiple vehicles. This consolidates what would traditionally require multiple separate controls into one device, maintaining comprehensive control capability while improving portability and comfort.
Data Source
AI summary
A security system is disclosed with a digital processor-based wireless remote controller that sends command to perform system operations and receive confirmation of various aspects of the system. The security system monitors environmental and vehicle system parameters and automatically provides commands or prohibits issuance of commands to operate vehicles systems based on preset environmental and vehicle system conditions. The system reports command and response status to users through the remote controller.
