Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single high-power processing unit is used to support both navigation and anti-theft functions, then the system functionality is complete, but power consumption and production cost increase
Solution Approach 1:
The system divides processing units into multiple segments with different computing powers (first processing unit with higher computing power for navigation, second processing unit with lower computing power for anti-theft). This segmentation allows each unit to be optimized for its specific function, reducing overall power consumption while maintaining complete system functionality.
Solution Approach 2:
The patent implements multi-functionality by enabling both processing units to perform vehicle protection functions, while the controller dynamically selects which unit handles specific tasks based on operational states. This allows the system to adaptively allocate resources, using the more powerful unit only when necessary and the lower-power unit for routine operations.
2Adaptability or versatility
If a single high-power processing unit is used to support both navigation and anti-theft functions, then the system functionality is complete, but production cost increases
Solution Approach 1:
The system segments processing capabilities into two separate units with different computing powers, allowing each unit to be manufactured to its specific performance requirements rather than both requiring high-end specifications. This reduces overall production cost while maintaining complete system functionality.
Solution Approach 2:
The patent applies local quality by assigning different computing power levels to different processing units based on their specific functional requirements. The navigation function receives higher computing power allocation while anti-theft functions use lower computing power, optimizing resource distribution and reducing production costs.
3Reliability
If the high-power processing unit is always used for vehicle protection, then processing capability is sufficient, but power consumption increases
Solution Approach 1:
The system implements dynamics by enabling the controller to dynamically switch between processing units based on operational states. The high-power first processing unit is activated only when complex navigation processing is required, while the low-power second processing unit handles routine vehicle protection tasks, optimizing the balance between processing capability and power consumption.
Solution Approach 2:
The patent changes the operational parameter of processing unit selection based on system state. The controller monitors operational states and adjusts which processing unit is active, changing the power consumption parameter while maintaining sufficient processing capability through adaptive parameter adjustment.
4Reliability
If conventional alarm systems are used without mobile phone integration, then system simplicity is maintained, but anti-theft performance is limited
Solution Approach 1:
The system merges the conventional alarm system with mobile phone positioning and communication capabilities into an integrated anti-theft system. The vehicle protection circuit can now send positioning information and alarm information via mobile phone, combining multiple functions into a unified system that improves anti-theft performance while managing complexity through integration.
Solution Approach 2:
The vehicle protection circuit is designed with multi-functionality, serving both as a traditional alarm system and as a positioning/communication system when theft is detected. This universal design allows the same hardware to perform multiple functions, improving anti-theft capabilities without proportionally increasing system complexity.

AI summary
An in-vehicle protection system includes a signal input interface and a vehicle protection circuit. The signal input interface is arranged to receive at least an indication signal indicative of a status of a vehicle. The vehicle protection circuit includes a first processing unit, a second processing unit, and a controller. Each of the first processing unit and the second processing unit is capable of performing vehicle protection upon the vehicle, where computing power of the first processing unit is different from computing power of the second processing unit. The controller is used for receiving the indication signal, outputting the received indication signal to the first processing unit for further processing when the in-vehicle protection system operates under a first operational state, and outputting the received indication signal to the second processing unit for further processing when the in-vehicle protection system operates under a second operational state.
