Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual weight measurement and handling is used for meter calibration, then the calibration process can be performed with simple equipment, but the calibration is laborious, time-consuming, and prone to inaccuracies
Solution Approach 1:
The patent replaces manual mechanical weight measurement with electronic weight sensors that automatically detect and transmit weight data to the controller. This substitution eliminates manual handling operations and provides continuous, precise weight measurements during the calibration process, thereby improving both accuracy and reducing calibration time.
Solution Approach 2:
The calibration system performs self-measurement through integrated weight sensors that automatically track the weight of bulk material as it is dispensed. The system self-calculates calibration factors by comparing expected versus actual dispensed amounts, eliminating the need for external manual measurement devices and operations.
2Ease of operation
If manual weight measurement and handling is used for meter calibration, then the equipment complexity is low, but the calibration process is laborious and prone to inaccuracies
Solution Approach 1:
The patent merges the weight measurement function directly into the calibration container by integrating electronic weight sensors within the container structure. This combination eliminates the need for separate manual measurement devices and operations, making the calibration process easier to perform while the increased complexity is confined to the integrated sensor system.
Solution Approach 2:
The system performs automatic weight detection and data processing through integrated sensors and a controller that self-calculate calibration factors. This automation simplifies the operator's task to merely initiating the calibration process, while the system handles all measurement and calculation operations independently.
3Productivity
If automated weight sensing and electronic communication are used for calibration, then calibration speed and accuracy are improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple functions (bulk material collection, weight sensing, data processing, and calibration calculation) into a single integrated calibration container system. This merging enables automated calibration operations that improve productivity while consolidating complexity into one modular unit rather than requiring multiple separate complex systems.
Solution Approach 2:
The controller acts as an intermediary that receives weight data from the electronic sensors, processes the information, and automatically calculates calibration factors. This intermediary component enables automated high-speed calibration operations while managing the system's complexity through centralized intelligent control.
