Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual or conventional arrissing methods are used, then operator flexibility is maintained, but production time is prolonged and quality is suboptimal
Solution Approach 1:
The machine performs arrissing operations automatically without continuous operator intervention. The probe detects edge positions and the abrasive tool grinds edges autonomously based on detected misalignment, eliminating manual handling while maintaining quality standards.
Solution Approach 2:
Manual mechanical arrissing operations are replaced with an automated system combining optical probes for detection and mechanical abrasive tools for grinding. The system substitutes human operators with an automated detection-grinding cycle that achieves both speed and precision.
2Reliability
If complex maintenance procedures are implemented, then machine reliability is improved, but device complexity increases
Solution Approach 1:
The probe and abrasive tool system is designed for self-adjustment during operation. The probe automatically detects edge positions and triggers tool repositioning without requiring manual intervention or complex maintenance procedures, simplifying operation while maintaining reliability.
Solution Approach 2:
The system incorporates dynamic adjustment capabilities where the abrasive tool automatically repositions based on real-time probe detection of edge misalignment. This dynamic self-correction eliminates the need for complex manual adjustment mechanisms and reduces maintenance requirements.
3Adaptability or versatility
If irregularly shaped glass sheets are processed, then adaptability is improved, but manufacturing precision deteriorates
Solution Approach 1:
The probe continuously detects the actual position of glass sheet edges and provides feedback to the control system. Based on this feedback, the abrasive tool automatically adjusts its position and grinding parameters to compensate for irregular shapes, maintaining symmetrical beveling precision across various geometries.
Solution Approach 2:
The system employs dynamic positioning of the abrasive tool that adapts in real-time to the detected edge geometry. The tool movement and grinding parameters are continuously adjusted according to the probe's detection of misalignment, enabling precise beveling of irregular shapes while maintaining manufacturing precision.
