Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional tracing methods are used for three-dimensional objects, then the process can be completed, but the efficiency is low and the operation is challenging
Solution Approach 1:
The patent replaces traditional mechanical tracing methods with a magnetic field-based system. The magnetic virtual inking effect allows the input object to be attracted to and follow the contours and edges of the target object without physical contact, substituting mechanical tracing with magnetic field interaction. This resolves the contradiction by making the operation easier while maintaining high tracing efficiency through the intuitive magnetic attraction mechanism.
Solution Approach 2:
The patent introduces magnetic field lines as an intermediary between the input object and the target object. These magnetic field lines create the virtual inking effect that guides the input object along the contours of the target object. This intermediary mechanism simplifies the tracing operation by providing a visual and magnetic guide, while maintaining high efficiency through direct magnetic attraction without physical contact.
2Measurement precision
If direct contact tracing is used, then accurate tracing can be achieved, but the process requires direct contact which limits versatility
Solution Approach 1:
The patent substitutes direct mechanical contact with magnetic field interaction. The magnetic virtual inking effect allows the input object to follow the contours of the target object through magnetic attraction without physical contact. This maintains tracing accuracy by keeping the input object precisely aligned with the target contours while significantly improving versatility by enabling tracing of objects that are difficult to touch or manipulate physically.
3Measurement precision
If virtual ink is applied without smoothing, then the tracing follows the input object movement exactly, but the result appears jagged and less accurate
Solution Approach 1:
The patent applies smoothing algorithms to the virtual ink to create a continuous, smooth tracing line. The smoothing process processes the virtual ink data to eliminate jagged edges and create a continuous contour representation. This resolves the contradiction by improving tracing smoothness and perceived accuracy while the computational complexity is managed through efficient algorithms that process the virtual ink data in real-time.
