Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If 2D static plots are used for payload sizing, then the information presentation is simple, but the measurement precision and reliability are insufficient leading to human error
Solution Approach 1:
The patent transitions from 2D static plots to 3D interactive visualizations of the center of gravity envelope. This dimensional enhancement allows users to accurately determine payload parameters by visualizing the three-dimensional space where the payload center of gravity must remain, eliminating the need for manual interpolation and judgment required by 2D plots.
2Adaptability or versatility
If 2D envelope plots with discrete options are used, then the device complexity is low, but the adaptability is insufficient for custom configurations
Solution Approach 1:
The patent implements an interactive tool where users can dynamically adjust operating parameters such as speed, payload mass, and incline conditions. The system responds in real-time by updating the 3D center of gravity envelope visualization, allowing adaptation to any custom configuration without requiring discrete pre-defined options.
3Ease of operation
If expert guidance is required for payload determination, then the measurement precision can be high, but the ease of operation deteriorates
Solution Approach 1:
The patent creates a self-service system where users can independently determine accurate payload parameters by interacting with the 3D visualization tool. The system automatically calculates and displays the center of gravity envelope based on user-input parameters, eliminating the need for expert judgment while maintaining high precision through automated computational geometry.
4Reliability
If manual judgment and interpolation are required, then the device complexity is low, but the reliability deteriorates due to human error
Solution Approach 1:
The patent replaces manual mechanical judgment and interpolation processes with automated computational systems. The software automatically calculates the center of gravity envelope boundaries and provides visual feedback, eliminating human error while maintaining system accessibility through an intuitive graphical interface.
