Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed central control unit is used for monitoring, then the system structure is simple and easy to control, but the adaptability to changing conditions and flexibility in response to different operating states is reduced
Solution Approach 1:
The monitoring system is segmented into multiple independent sensor units distributed across stationary and mobile devices. Each sensor unit autonomously performs detection and communicates findings to other units, eliminating the need for a single central control unit while improving adaptability to changing conditions.
Solution Approach 2:
The system transitions from a static centralized structure to a dynamic decentralized architecture where sensor units can be added, removed, or repositioned independently. This dynamic configuration allows the system to adapt flexibly to changing operational requirements and environmental conditions.
2Adaptability or versatility
If sensors only perform object detection without communication capabilities, then the device complexity is low, but the ability to adapt monitoring functionalities to changing boundary conditions is limited
Solution Approach 1:
Sensor units are designed with multi-functionality, combining detection capabilities with communication functions. Each sensor can both detect objects/conditions and actively participate in defining monitoring functionalities through inter-sensor communication, allowing the system to adapt to various operating modes and boundary conditions.
Solution Approach 2:
Inter-sensor communication establishes feedback loops where sensor units exchange information about detected conditions and their own operational states. This feedback enables the network to dynamically adjust monitoring functionalities based on aggregated information from multiple sensors, improving overall system adaptability.
3Productivity
If monitoring functionalities are statically defined, then the system is easier to implement and control, but it cannot automatically adapt to changing operating modes and states
Solution Approach 1:
The sensor network performs self-configuration and self-adaptation through autonomous inter-sensor communication. Sensor units automatically adjust monitoring functionalities based on their detected environment and communicated information from peers, eliminating the need for complex external control systems while maintaining high monitoring efficiency.
Solution Approach 2:
Sensor units are pre-equipped with communication capabilities and detection algorithms that enable them to autonomously adapt to changing conditions without requiring real-time external intervention. This preliminary preparation allows rapid response to changing operating modes while keeping the control system simple.
