Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rear laser sensor is added to detect obstacles, then obstacle detection capability is improved, but device complexity increases
Solution Approach 1:
The laser sensor is integrated into the mobile terminal to perform multiple functions: obstacle detection, distance measurement, and providing spatial information for augmented reality applications. This multi-functional approach justifies the addition of the sensor by making it serve several purposes within the device.
Solution Approach 2:
The laser sensor acts as an intermediary component that bridges the gap between the mobile terminal and the physical environment, enabling the device to perceive obstacles and distances. By introducing this specialized sensor, the system gains environmental awareness without requiring complete redesign of the terminal architecture.
2Speed
If the laser sensor is activated continuously to detect obstacles in real time, then obstacle detection responsiveness is improved, but energy consumption increases
Solution Approach 1:
The laser sensor is activated periodically or on-demand rather than continuously. The controller activates the laser sensor based on detected events or at scheduled intervals, allowing the system to maintain real-time obstacle detection capability while significantly reducing energy consumption compared to continuous operation.
Solution Approach 2:
The system activates the laser sensor in advance or in response to specific triggers (such as detected movement or entered zones), preparing for potential obstacle detection scenarios without maintaining constant sensor operation. This event-driven activation strategy balances responsiveness with energy efficiency.
