Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the machine tool is designed for various machining situations to be general-purpose, then the adaptability is improved, but the device complexity and cost increase due to over-specification of components
Solution Approach 1:
The system performs preliminary action by detecting operation signals and calculating actual load conditions before finalizing the component selection. This allows the design to be based on real measured data rather than assumptions, enabling general-purpose capability without over-specification.
Solution Approach 2:
The system changes parameters by using actual load conditions derived from detected operation signals to determine component specifications. This dynamic parameter adjustment allows the machine tool to be optimized for specific machining situations while maintaining adaptability through the ability to re-evaluate based on actual usage patterns.
2Ease of manufacture
If the designer assumes a machining situation to estimate load conditions, then the design process is simplified, but the manufacturing precision of the design matches poorly with actual requirements
Solution Approach 1:
The system applies feedback by detecting operation signals from the actual machining process and using these signals to calculate and refine load conditions. This closed-loop approach continuously improves design accuracy by incorporating real operational data, eliminating the need for inaccurate assumptions while maintaining design simplicity.
Solution Approach 2:
The system replaces the mechanical estimation process with an automated detection and calculation system. Operation signals are automatically detected and processed to determine load conditions, substituting manual assumption-based estimation with precise measurement-based determination, thereby improving design accuracy without significantly complicating the process.
3Productivity
If components are selected based on assumed load conditions, then the initial design can be completed quickly, but the reliability of the feed drive system is reduced due to mismatch with actual machining conditions
Solution Approach 1:
The system performs preliminary detection of operation signals and calculation of actual load conditions before component selection is finalized. This preliminary action ensures that components are selected based on real data, improving reliability while maintaining efficient design completion through automated processing.
Solution Approach 2:
The system uses feedback from detected operation signals to continuously refine load condition estimates and optimize component selection. This feedback mechanism ensures that the feed drive system is reliably matched to actual machining conditions while the automated nature of the process maintains high productivity in the design completion.
