Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional mechanical scales (Marcy Scale) are used to measure solid concentration, then the device structure is simple, but measurement precision deteriorates due to operator dependency and parallax errors
Solution Approach 1:
The patent replaces the traditional mechanical pointer scale system with an electronic measurement and digital display system. Load cells provide electronic weight measurement, ADC converts signals to digital values, and LCD displays results digitally, eliminating mechanical parallax errors and operator dependency while maintaining relatively simple device structure.
Solution Approach 2:
The device integrates multiple functions into a single system: weight measurement, density calculation, temperature compensation, and digital data storage. This multi-functionality improves measurement precision while the integrated design prevents excessive complexity increase.
2Reliability
If analog devices are used for measuring solid concentration, then the device structure is simple, but reliability deteriorates due to lack of data collection and storage capabilities
Solution Approach 1:
The device automatically collects measurement data, calculates density and solid concentration, compensates for temperature effects, and stores results in EEPROM memory. This automated self-service capability improves reliability by eliminating manual calculation errors and providing permanent data records, while the microcontroller handles these functions efficiently without proportionally increasing complexity.
Solution Approach 2:
The system incorporates temperature sensing with automatic temperature compensation feedback to the measurement calculations. This feedback mechanism improves measurement reliability by correcting for thermal expansion effects, and the integrated temperature sensor and processing keep the overall device complexity manageable.
3Adaptability or versatility
If specialized measuring devices are used for specific fields, then measurement precision is improved for that field, but adaptability deteriorates due to limited application scope
Solution Approach 1:
The device is designed as a universal multi-functional instrument that can measure weight, calculate density, determine solid concentration, and compensate for temperature effects across various applications. The microcontroller-based system with programmable calculations adapts to different measurement needs while maintaining precision through electronic computation rather than field-specific mechanical designs.
Solution Approach 2:
The device allows dynamic parameter input and adjustment, including user-defined calibration factors, temperature compensation parameters, and customizable calculation methods. This flexibility enables adaptation to different fields (mining, food, chemistry, etc.) while maintaining measurement precision through electronic parameter control rather than physical redesign.
4Loss of information
If manual calculation methods are used (as in MAXX DP scale), then device complexity is reduced, but loss of information increases due to lack of automated data processing
Solution Approach 1:
The device automatically performs all calculations including weight measurement, density computation, solid concentration determination, and temperature compensation. The microcontroller executes programmed algorithms to process raw data into meaningful results, eliminating manual calculation errors and information loss, while the integrated processing keeps complexity increases minimal.
Solution Approach 2:
The ADC (analog-to-digital converter) and microcontroller act as intermediaries between the physical measurement (weight) and the final displayed information. This intermediary processing chain ensures accurate data conversion, calculation, and storage without information loss, while the compact electronic components prevent excessive complexity.
