Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional component combination methods are used to meet required specifications, then component selection is simplified, but the intended force or magnetic attraction is not achieved
Solution Approach 1:
The patent applies parameter changes by systematically varying key parameters such as field magnet length, armature length, and gap distance to observe their effects on force and magnetic attraction. This allows the selection of component combinations that actually achieve the intended performance rather than just meeting minimum specifications.
Solution Approach 2:
The patent implements feedback by measuring the actual force and magnetic attraction achieved by assembled linear motors and using this information to refine the component selection process. This feedback loop ensures that selected configurations actually deliver the required performance characteristics.
2Measurement precision
If detailed calculations of force and magnetic attraction are performed to ensure performance, then selection accuracy is improved, but calculation complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-calculating and storing the relationships between component parameters and performance characteristics in databases. This allows rapid retrieval and comparison of potential configurations without performing complex calculations during the actual selection process, thereby reducing computational complexity while maintaining accuracy.
Solution Approach 2:
The patent uses approximate expressions as intermediaries to simplify the complex relationship between component parameters and force/magnetic attraction. These approximate expressions provide sufficiently accurate predictions without requiring full-scale complex calculations, thus reducing computational burden while maintaining selection accuracy.
