Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a robot cleaner is used to automate cleaning, then labor cost is reduced and cleaning can be performed on complex floor plans, but the device complexity increases and requires sophisticated navigation systems
Solution Approach 1:
The robot cleaner is divided into multiple independent modules including a main body, separate sensor units, and modular cleaning components. This segmentation allows each module to perform specific functions independently, reducing overall system complexity while maintaining automation capabilities.
Solution Approach 2:
The robot cleaner is designed with multi-functional capabilities including navigation, obstacle detection, cleaning, and self-charging all integrated into a single device. This universality reduces the need for multiple separate systems, thereby managing device complexity while achieving high automation.
2Reliability
If sensors and ultrasonic waves are used for obstacle detection and navigation, then the robot can avoid obstacles and navigate complex floor plans, but the device complexity increases
Solution Approach 1:
Multiple sensing functions including ultrasonic detection, infrared sensing, and collision detection are merged into integrated sensor units. This consolidation reduces the number of separate components needed while maintaining comprehensive obstacle detection and navigation reliability.
Solution Approach 2:
Ultrasonic waves and infrared signals serve as intermediary carriers for distance measurement and obstacle detection. These physical phenomena mediate between the robot's sensors and the environment, enabling reliable detection without requiring complex direct measurement systems.
3Duration of action of stationary object
If the robot returns to the charging station autonomously, then continuous operation is enabled, but the navigation system complexity increases
Solution Approach 1:
The robot establishes wireless communication and positioning systems in advance that continuously track its location relative to the charging station. This preliminary setup enables autonomous return navigation without requiring complex real-time decision-making, simplifying the navigation system while ensuring continuous operation capability.
