Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the operator moves the scanner faster through the environment, then the scanning productivity increases, but the data density decreases and tracking may be lost
Solution Approach 1:
The system continuously monitors scan quality attributes such as data density and tracking stability, then provides real-time visual feedback through quality indicators displayed on the graphical user interface. This feedback loop enables the operator to adjust scanning speed dynamically to maintain optimal data quality while maximizing productivity.
Solution Approach 2:
The quality indicator incorporates movable elements that dynamically change position, size, or configuration based on real-time scan quality assessment. This dynamic visualization adapts to varying scanning conditions, allowing the operator to respond appropriately to changing data quality levels during the scanning process.
2Loss of time
If the operator moves the scanner faster through the environment, then the scanning time decreases, but the measurement precision deteriorates
Solution Approach 1:
Real-time monitoring of data density and scan quality attributes provides continuous feedback to the operator through visual indicators. This enables the operator to optimize the balance between scanning speed and data density, reducing total scanning time while maintaining measurement precision through informed speed adjustments.
Solution Approach 2:
The system evaluates multiple scan quality attributes including data density, tracking stability, and scanner movement characteristics. Based on this evaluation, the quality indicator dynamically adjusts its presentation parameters to guide the operator in modifying scanning parameters to achieve optimal data density within reduced time frames.
3Ease of operation
If the system provides detailed quality feedback to the operator, then the ease of operation improves, but the device complexity increases
Solution Approach 1:
The quality indicator focuses on displaying specific, critical quality attributes at relevant locations in the graphical user interface rather than overwhelming the operator with comprehensive data. This selective presentation of information enhances ease of operation by highlighting only the most important quality metrics that require operator attention.
Solution Approach 2:
The quality indicator utilizes color variations to communicate scan quality status and attribute levels intuitively. Different colors represent different quality ranges or states, allowing the operator to quickly assess scan quality without complex numerical data, thereby improving ease of operation while maintaining manageable interface complexity.
