Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual data recording is used, then simplicity of operation is maintained, but reliability and accuracy of data deteriorate due to potential fabrication and errors
Solution Approach 1:
The patent combines the water quality meter with a smartphone, merging the measurement function with data recording, processing, and communication functions into a single integrated system. This eliminates manual recording while maintaining operational simplicity through the smartphone's user interface.
Solution Approach 2:
The system enables self-service by having the smartphone automatically record, store, and manage water quality data without requiring manual transcription. The smartphone serves itself by handling data capture, storage, and preliminary analysis, freeing the operator from tedious manual tasks.
2Productivity
If manual data arrangement is performed, then device complexity is reduced, but time consumption and productivity deteriorate
Solution Approach 1:
The patent replaces the mechanical process of manual data arrangement with automated electronic data processing. The smartphone's calculation unit automatically organizes, analyzes, and prepares data for reporting, eliminating the time-consuming manual sorting and arrangement process.
Solution Approach 2:
The system performs preliminary data processing and arrangement automatically as data is being collected. The smartphone pre-organizes data in structured formats and prepares it for immediate analysis or reporting, eliminating the need for post-collection data arrangement work.
3Measurement precision
If GPS unit is added to the smartphone, then position accuracy is improved, but device complexity and cost increase
Solution Approach 1:
The smartphone serves multiple functions: it acts as the user interface for the water quality meter, provides GPS location tracking, stores data, performs calculations, and enables communication. By making the smartphone a multi-functional device, the added GPS capability does not significantly increase overall system complexity since the smartphone already handles numerous other functions.
