Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a non-electronic timing fuse is used to fire the break charge, then the device complexity is reduced, but the measurement precision of timing is worsened
Solution Approach 1:
The patent replaces the mechanical timing fuse system with an electronic timing circuit that uses a microprocessor and voltage storage component. This substitution eliminates the need for physical fuse delays while achieving precise electronic timing control for the break charge ignition.
Solution Approach 2:
The patent changes the timing mechanism from chemical burn rate parameters to electronic time delay parameters. The microprocessor controls the timing precision by programming specific delay intervals, allowing for accurate control of when the break charge fires relative to the lift charge ignition.
2Ease of manufacture
If black-powder match and slow-burning chemical timing fuse are used, then the ease of manufacture is improved, but the measurement precision of timing is worsened
Solution Approach 1:
The patent replaces chemical timing fuses with an electronic timing circuit containing a microprocessor and voltage storage component. This substitution maintains ease of manufacture through standardized electronic components while dramatically improving timing precision through electronic control.
3Adaptability or versatility
If electronic ignition system is used for lift charge but non-electronic fuse for break charge, then the adaptability is improved, but the measurement precision of timing is worsened
Solution Approach 1:
The patent merges the electronic ignition system for the lift charge with an electronic timing circuit for the break charge into a unified system. The microprocessor coordinates both ignitions, providing precise timing control for both charges while maintaining the adaptability of electronic control throughout the entire system.
