Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional grinding tools are used for processing stratified glass materials, then the processing operation can be performed, but the tool deteriorates early and produces poor product quality due to incomplete removal of plastic residues
Solution Approach 1:
The grinding tool is segmented into multiple functional zones: peripheral grinding sections for general edge processing and a central toothed section specifically designed for plastic material removal. This segmentation allows each zone to perform its specialized function, preventing the tool from deteriorating due to attempting to handle both glass and plastic materials uniformly.
Solution Approach 2:
Different portions of the grinding tool have different geometric characteristics and material properties. The central toothed portion has specific geometry optimized for cutting plastic, while the peripheral sections are optimized for glass grinding. This local differentiation ensures that each part of the tool maintains its functionality longer and produces higher quality results in its designated area.
2Ease of operation
If conventional grinding tools process stratified glass with interposed plastic films, then the glass edges can be rounded, but plastic residues remain causing opacity and poor product quality
Solution Approach 1:
The central toothed section is positioned to act on the plastic material before the peripheral grinding sections process the glass edges. This preliminary removal of plastic prevents residues from interfering with the subsequent glass grinding operation, ensuring both ease of operation and high manufacturing precision.
Solution Approach 2:
The invention extracts the plastic material removal function from the general glass grinding operation by adding a dedicated central toothed section. This separation ensures that plastic is completely removed without interfering with the glass edge rounding process, eliminating opacity issues while maintaining operational simplicity.
3Productivity
If the grinding tool removes plastic material through rubbing and rotation, then some plastic is processed, but the motion drives plastic along the sheet causing opacity and incomplete removal
Solution Approach 1:
Instead of using the conventional rubbing and rotating motion that drives plastic along the sheet, the invention uses a central toothed section that cuts and lifts plastic material upward and outward from the processing zone. This inverted approach prevents plastic from being driven along the sheet while maintaining high productivity and complete removal.
4Temperature
If the grinding tool is designed with holes and cuts for water passage, then cooling and flushing are improved, but plastic material still obstructs the processing and is not completely unloaded
Solution Approach 1:
The invention extracts the plastic removal function into a dedicated central toothed section that is specifically designed to cut and eject plastic material. This separation ensures that plastic is completely removed and unloaded from the processing zone, while the holes and cuts continue to provide effective cooling and flushing without obstruction.
