Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mobile dimensioning device uses predetermined accuracy divisions, then it can be compatible with NIST standards, but it cannot adapt to dynamic measurement environments where parameters like distance and viewing angle vary
Solution Approach 1:
The patent implements dynamic accuracy division by continuously monitoring measurement parameters (distance, viewing angle, ambient light) and adjusting the accuracy division in real-time based on current environmental conditions. This allows the mobile dimensioning device to adapt to varying measurement scenarios while maintaining NIST compliance through proper reporting of the dynamic accuracy division for each measurement.
Solution Approach 2:
The system incorporates feedback mechanisms where sensors continuously monitor measurement parameters and feed this information back to the processor. The processor then adjusts the accuracy division based on the feedback from environmental conditions, ensuring optimal measurement accuracy while maintaining compliance with NIST standards through accurate reporting.
2Adaptability or versatility
If a mobile dimensioning device allows parameters like distance and viewing angle to vary dynamically, then it gains mobility and versatility, but measurement precision deteriorates due to uncontrolled environmental factors
Solution Approach 1:
Sensors continuously monitor measurement parameters including distance to object, viewing angle, and ambient light conditions. This feedback is processed to dynamically adjust the accuracy division, ensuring measurement precision is maintained despite environmental variations by compensating for suboptimal conditions through appropriate accuracy reporting.
Solution Approach 2:
The system changes the accuracy division parameter dynamically based on measured environmental conditions. When distance, viewing angle, or lighting conditions deviate from optimal ranges, the accuracy division is adjusted to reflect the actual measurement quality, thereby maintaining measurement precision through accurate uncertainty characterization.
3Measurement precision
If a mobile dimensioning device implements dynamic accuracy division, then it can optimize measurements for different environments, but device complexity increases due to additional sensors and processing requirements
Solution Approach 1:
The mobile dimensioning device integrates multiple sensors (optical sensors for distance and viewing angle, ambient light sensors) that serve multiple functions. These sensors not only monitor environmental parameters for dynamic accuracy adjustment but also contribute to overall object characterization and measurement optimization, reducing the need for separate dedicated components.
Solution Approach 2:
The system uses the mobile device's existing sensors and processing capabilities to self-monitor and self-adjust the accuracy division based on environmental conditions. The device serves itself by utilizing its own computational resources and sensor data to optimize measurements without requiring external calibration equipment or complex additional hardware.

AI summary
A mobile dimensioning device, i.e. a mobile dimensioner, is described that uses a dynamic accuracy while still being compatible with the NIST standard. Even if the accuracy division is dynamic and not predetermined, a mobile dimensioning device of the present invention reports the actual dimensioning prior to measurement capture and can therefore be certified and used in commercial transactions.
