Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manufacturer-specific communication interfaces are used for data transmission between working machines and additional units, then communication reliability within the same manufacturer system is improved, but compatibility with equipment from different manufacturers deteriorates
Solution Approach 1:
The patent implements a universal data transmission interface that can communicate with both manufacturer-specific systems and generic systems. The evaluation device includes multiple communication interfaces that can adapt to different manufacturers' protocols while maintaining a standardized external interface, allowing the same device to work with equipment from any manufacturer without requiring manufacturer-specific customization.
Solution Approach 2:
The evaluation device acts as an intermediary between the additional unit and the higher-level management system. It receives data from the additional unit through a standardized interface, processes and evaluates the data, and then transmits results to the management system using appropriate communication protocols. This intermediary role enables compatibility between different manufacturers' equipment while maintaining reliable communication.
2Ease of manufacture
If active transmission modules are installed on additional units for wireless data transmission, then ease of retrofitting and installation is improved, but energy consumption increases
Solution Approach 1:
The transmission module is designed to transmit data at periodic intervals rather than continuously. The module can be configured to transmit operating status data at predetermined time intervals or when specific events occur, significantly reducing energy consumption compared to continuous transmission while still providing timely data for evaluation and monitoring purposes.
Solution Approach 2:
The transmission module includes integrated sensors that automatically detect operating parameters and trigger data transmission when relevant changes occur. The system self-manages its transmission schedule based on actual operating conditions, transmitting data only when necessary rather than consuming energy for unnecessary transmissions.
3Measurement precision
If integrated sensors are added to transmission modules for independent data generation, then measurement capability is improved, but device complexity increases
Solution Approach 1:
The patent combines the transmission module with integrated sensors into a single unified device. The sensors are embedded within the transmission module housing, and the module processes both sensor data and received operating status data in one integrated unit. This merging approach provides comprehensive measurement capabilities while avoiding the complexity of separate sensor systems and reducing the number of discrete components that would need to be installed and configured.
