Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If conventional operation control methods are used to control moving body travel, then the control system can be implemented with basic position feedback, but the calculated route is not suitable and the time to return to the ideal route is excessive
Solution Approach 1:
The patent transforms the path calculation problem by changing parameters from conventional single-distance feedback to composite parameters including perpendicular distance, parallel distance, and deviation angle. This parameter transformation enables more suitable path calculation that reduces return time to the ideal route while maintaining reasonable system complexity
Solution Approach 2:
The patent introduces a new dimensional approach by calculating paths in two dimensions (perpendicular and parallel distances to the ideal route) rather than conventional one-dimensional distance feedback. This dimensional expansion allows for more accurate and suitable path calculation, directly addressing the time loss problem
2Measurement precision
If the moving body deviates from the ideal route, then position adjustment is needed, but conventional methods lack accuracy in determining the suitable correction path
Solution Approach 1:
The patent improves measurement precision by changing from simple distance measurement to composite parameter measurement including perpendicular distance, parallel distance, and deviation angle. This comprehensive parameter set provides accurate deviation information while the calculation methods remain computationally manageable
Solution Approach 2:
The patent segments the deviation measurement into three independent components: perpendicular distance, parallel distance, and deviation angle. This segmentation allows for precise measurement of each aspect of deviation independently, improving overall measurement accuracy while keeping individual calculations simple
3Productivity
If basic distance feedback is used for path control, then the control algorithm is simple, but the calculated path does not optimize for minimal deviation and efficient route correction
Solution Approach 1:
The patent enhances productivity by transforming the control algorithm to use composite parameters (perpendicular distance, parallel distance, deviation angle) that directly relate to efficient route correction. This parameter transformation enables the system to calculate optimal paths that minimize deviation and improve correction efficiency
Solution Approach 2:
The patent implements a feedback mechanism where the calculated path based on composite parameters is continuously compared with the actual moving body position. This feedback loop enables real-time path optimization and efficient route correction, significantly improving productivity

AI summary
To calculate a path of movement of a moving body, a moving-body path calculation device includes: a deviation obtaining means that obtains a deviation of the moving body in a direction perpendicular to an ideal route; and a path calculating means that calculates the path of the movement of the moving body on a basis of a composite parameter including a parameter indicating the deviation of the moving body which deviation has been obtained by the deviation obtaining means.
