Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If various shot condition parameters are adjusted to achieve desired intensity, then processing quality improves, but the complexity of selecting appropriate parameters increases
Solution Approach 1:
The system employs a feedback mechanism where the actual shot intensity is measured during processing and compared against the target intensity. Based on this comparison, the control device automatically adjusts shot condition parameters (projection pressure, amount, type, distance, diameter) to minimize the difference between actual and target intensity, eliminating the need for manual parameter selection expertise
Solution Approach 2:
The patent replaces manual parameter adjustment with an automated control system that uses measurement data to dynamically adjust shot conditions. This substitution of manual mechanical adjustment with an automated feedback-controlled system resolves the complexity of parameter selection while maintaining processing quality
2Ease of operation
If shot condition parameters are not properly set, then device operation becomes simpler, but processing quality deteriorates
Solution Approach 1:
The system performs self-adjustment by automatically measuring the actual shot intensity and correcting parameter deviations without operator intervention. The control device autonomously maintains optimal processing conditions by continuously comparing measured intensity against target values and adjusting parameters accordingly, achieving both ease of operation and high processing quality
Solution Approach 2:
The automated feedback loop continuously monitors shot intensity and adjusts parameters to maintain optimal processing conditions, enabling simple operation while ensuring consistent processing quality through real-time corrections
