Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual calibration of onboard vehicle scales is performed, then calibration can be completed, but transcription errors and user errors occur leading to measurement inaccuracies
Solution Approach 1:
The patent replaces manual calibration procedures with an automated electronic calibration system that uses wireless data transmission. The onboard scale automatically receives calibration data from a reference scale via wireless communication, eliminating manual transcription and user intervention. This substitution of manual mechanical calibration with automated electronic calibration resolves the contradiction by maintaining measurement precision while significantly improving calibration reliability through elimination of human error.
Solution Approach 2:
The onboard scale performs self-calibration by automatically receiving calibration data from the reference scale and adjusting its measurements accordingly. The system calibrates itself without requiring manual intervention, data entry, or user action. This self-service calibration approach maintains accurate weight measurements while ensuring reliable calibration by eliminating transcription errors and user mistakes inherent in manual processes.
2Reliability
If automatic calibration system is implemented, then transcription errors are reduced and measurement reliability improves, but device complexity increases
Solution Approach 1:
The onboard scale is designed with multi-functionality, serving both as a weight measurement device and as a calibrated measurement system that automatically receives calibration data. The wireless transceiver integrated into the scale serves dual purposes: communication with external systems and automatic calibration data reception. This universal design approach improves calibration reliability while minimizing additional system complexity by leveraging existing components for multiple functions.
Solution Approach 2:
The wireless transceiver acts as an intermediary component that enables automatic calibration without requiring complex direct integration between the onboard scale and reference scale. This intermediary communication interface simplifies the overall system architecture by providing a standard, off-the-shelf solution for data transmission, thereby improving calibration reliability while adding minimal complexity through the use of conventional wireless communication technology.
