Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual intervention is used for device location identification and conflict resolution, then mapping accuracy can be maintained, but time consumption and operational complexity increase significantly
Solution Approach 1:
The system enables processing devices to automatically perform location identification and mapping without human intervention. Each device autonomously determines its position by measuring wireless signal strengths from neighboring devices and comparing them against stored reference data, eliminating the need for manual mapping while maintaining high accuracy through self-service operations
Solution Approach 2:
Reference signal strength data is pre-collected and stored in a database during an initial setup phase. This preliminary action creates a reference framework that enables rapid automatic mapping during subsequent operations, reducing time consumption while preserving mapping accuracy through pre-prepared comparison data
2Productivity
If automatic mapping based on signal strength is implemented, then operational efficiency improves, but mapping accuracy may deteriorate due to signal interference and environmental factors
Solution Approach 1:
The system combines multiple signal strength measurements from different neighboring devices to determine the location of each processing device. By aggregating data from multiple sources rather than relying on single measurements, the system achieves both high operational efficiency and improved mapping accuracy through combined information
Solution Approach 2:
The system continuously compares measured signal strengths against stored reference data and adjusts location determinations accordingly. This feedback mechanism compensates for signal interference and environmental variations, maintaining mapping accuracy while enabling automatic operation at high speed
3Measurement precision
If comprehensive signal strength measurements from multiple devices are collected, then mapping accuracy improves, but system complexity and data processing requirements increase
Solution Approach 1:
The mapping system is divided into independent processing modules: signal strength measurement, data storage, comparison analysis, and location determination. Each module handles a specific aspect of the mapping process independently, reducing overall system complexity while maintaining high mapping accuracy through specialized processing at each stage
