Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a waveform is obtained from input numerical values and intersection of paths is checked, then machining safety is improved, but intuitiveness of machining state visualization deteriorates
Solution Approach 1:
The patent transforms the one-dimensional waveform data into a two-dimensional visualization by displaying the waveform along with projected tool paths on a screen. This dimensional expansion allows operators to simultaneously view both the waveform characteristics and the spatial relationship between tool paths, making the machining state more intuitive while maintaining safety checks
Solution Approach 2:
The patent introduces a display device as an intermediary between the numerical control system and the operator. This intermediary translates complex numerical values and waveform data into visual representations including waveform displays and tool path projections, bridging the gap between raw data and operator understanding
2Manufacturing precision
If detailed machining state data is calculated, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The patent makes the existing numerical control device perform multiple functions by adding the capability to generate and display waveforms and tool path projections alongside its traditional machining control functions. This multi-functionality allows detailed machining state analysis without requiring a separate dedicated system
Solution Approach 2:
The patent enables the machining system to automatically calculate and display its own machining state data including waveforms and tool paths. The system serves itself by using its internal computational resources to generate visualizations of its operating parameters, eliminating the need for external complex analysis equipment
