Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensors are mounted in the smart car to obtain sensing information, then driving control and assistance can be provided, but zones obstructed by buildings or other cars cannot be detected, increasing accident risk
Solution Approach 1:
The patent introduces a communication system as an intermediary between the smart car and other objects (vehicles, infrastructure). This intermediary enables information exchange about sensing blind zones, allowing the smart car to obtain sensing information from other objects that can perceive obstructed areas, thereby resolving the information loss problem without adding physical sensors to the smart car.
Solution Approach 2:
The patent transitions from a single-dimension sensing approach (relying solely on onboard sensors) to a multi-dimension information gathering approach by communicating with multiple external objects. This dimensional expansion allows the system to obtain sensing information from different spatial perspectives and sources, covering obstructed zones that individual sensors cannot detect.
2Ease of operation
If the smart car uses onboard sensors to detect objects, then driving assistance can be provided, but uncertainty and risk increase in zones from which sensors cannot obtain information
Solution Approach 1:
The patent implements a feedback mechanism where the smart car receives sensing information about blind zones from other objects through communication. This feedback loop provides critical safety information that compensates for the limitations of onboard sensors, reducing uncertainty and risk in obstructed zones while maintaining ease of driving assistance.
3Measurement precision
If multiple sensors are added to cover obstructed zones, then detection capability improves, but device complexity and cost increase
Solution Approach 1:
Instead of adding more physical sensors to the smart car, the patent uses communication technology as an intermediary to obtain sensing information from external objects. This approach achieves improved detection capability in blind zones without increasing the complexity of the smart car's sensor system, as the information is acquired through data exchange rather than additional hardware.
