Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a communication bus like CAN bus is used to connect elevator signalization devices, then device integration is achieved, but communication bandwidth is limited and customization is difficult
Solution Approach 1:
The patent segments the communication network into multiple independent communication ports on switching devices, allowing each port to handle traffic independently. This segmentation enables simultaneous support for multiple communication protocols and customization schemes without bandwidth contention, resolving the contradiction between customization capability and communication bandwidth.
Solution Approach 2:
The patent implements a universal communication architecture where switching devices can handle multiple communication protocols (CAN bus, Ethernet, wireless) through different ports. This multi-functionality allows the system to accommodate various customization needs while maintaining adequate bandwidth for each protocol type, thus resolving the contradiction between adaptability and bandwidth limitations.
2Productivity
If a communication bus like CAN bus is used to connect elevator signalization devices, then device integration is achieved, but communication bandwidth is limited
Solution Approach 1:
By segmenting the communication network into multiple ports with independent bandwidth allocation, the system achieves higher overall communication efficiency. Each port can be optimized for specific traffic types, preventing bandwidth bottlenecks and improving productivity without requiring a complete system overhaul.
Solution Approach 2:
The switching device acts as an intermediary between signalization devices and the central controller, intelligently routing traffic through appropriate ports. This mediation optimizes bandwidth utilization and improves communication efficiency by selecting the most appropriate communication path for each data type, thereby resolving the bandwidth limitation issue.
3Measurement precision
If network addresses are inquired from switching devices, then accurate device identification is achieved, but configuration complexity increases
Solution Approach 1:
The patent implements preliminary configuration where network addresses are pre-associated with communication ports during system setup. This preliminary action eliminates the need for complex real-time address discovery, reducing configuration complexity while maintaining accurate device identification through the pre-established address-port mappings.
Solution Approach 2:
The system employs feedback mechanisms where the control device receives network address information from switching devices and uses this feedback to automatically update its configuration database. This feedback loop simplifies the configuration process by automating address management while ensuring accurate device location tracking, resolving the contradiction between precision and complexity.
