Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single electrochromic window is controlled in isolation, then the control complexity is reduced, but the system lacks advanced features and reliability
Solution Approach 1:
The patent combines multiple single-window control systems into a networked multi-window control system. Each window maintains its own controller for simplicity, while controllers are merged through a communication network to provide centralized monitoring, fault detection, and coordinated control, thereby achieving both low individual complexity and high system reliability
Solution Approach 2:
The controller is designed with multi-functionality to handle both individual window control and networked system management. It can operate independently for basic functions while also participating in networked operations including fault detection, parameter optimization, and coordinated control with other windows, thus maintaining simplicity while adding reliability
2Adaptability or versatility
If electrochromic windows are installed in large commercial buildings, then the building control capabilities are improved, but the repair and replacement costs increase significantly
Solution Approach 1:
The system segments the large building's window control into independent modular units, each with its own controller. This allows individual windows or groups of windows to be controlled, monitored, and maintained separately. If one unit fails, only that specific unit needs repair rather than the entire building system, significantly reducing repair costs while maintaining comprehensive building control capabilities
Solution Approach 2:
The networked system implements continuous feedback monitoring of each window's operational status, health parameters, and performance metrics. This enables early detection of potential failures, allowing maintenance to be scheduled proactively before complete failure occurs, reducing emergency repair costs and downtime for large building installations
3Adaptability or versatility
If sophisticated controllers are used for large installations, then the control features are enhanced, but the device complexity and failure risk increase
Solution Approach 1:
The sophisticated control functionality is segmented and distributed across multiple simple individual controllers rather than concentrated in one complex central controller. Each controller handles basic control functions locally, while advanced features emerge from the networked interaction between controllers, reducing individual device complexity while maintaining overall system versatility
Solution Approach 2:
A communication network acts as an intermediary between simple individual controllers, enabling them to achieve sophisticated control capabilities through coordinated interaction. The network mediates information exchange and control signals, allowing basic controllers to function as part of a complex system without themselves becoming complex
4Manufacturing precision
If manual configuration and parameter adjustment are performed for each window, then the installation precision is maintained, but the installation time and labor costs increase
Solution Approach 1:
Controllers are pre-configured with default parameters and identification information before installation. During installation, the system automatically detects and configures each controller based on its pre-stored identification data, eliminating the need for manual parameter adjustment while ensuring correct configuration. This preliminary preparation maintains installation precision while dramatically reducing installation time
