Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If bell-type equipment is used to maintain continuity of glaze film, then glaze application coverage is improved, but material waste increases significantly
Solution Approach 1:
The glazing equipment divides the glaze application into multiple discrete nozzles arranged in rows, each nozzle applying glaze to a specific zone. This segmentation allows precise control of glaze distribution, eliminating the excessive material waste associated with bell-type equipment while maintaining continuous coverage through coordinated nozzle operation.
Solution Approach 2:
The patent implements nozzles with locally optimized characteristics, including variable spray patterns and adjustable flow rates for different zones. This allows tailored glaze application to specific areas of the tile surface, ensuring adequate coverage where needed while minimizing waste in other areas, directly addressing the material efficiency problem.
2Area of stationary object
If bell-type equipment is used to cover entire tile surface, then coverage area is improved, but glaze application uniformity deteriorates
Solution Approach 1:
The glazing system segments the coverage area into multiple zones, each served by dedicated nozzles or nozzle groups. This segmentation enables independent control of glaze application in different regions, allowing the system to maintain uniformity across the entire tile surface while achieving complete coverage, directly resolving the uniformity problem of bell-type equipment.
Solution Approach 2:
The patent incorporates adjustable and controllable nozzle systems that can dynamically modify spray patterns, flow rates, and positioning. This dynamic capability allows real-time optimization of glaze distribution across the tile surface, ensuring uniform application regardless of tile size or shape, thereby solving the uniformity issue.
3Loss of substance
If multiple nozzles are used to dispense glaze strips, then material waste is reduced, but shading appears at strip junction areas
Solution Approach 1:
The patent merges multiple nozzle outputs into a coordinated system where glaze strips overlap or meet without gaps. The nozzles are positioned and controlled to ensure continuous glaze deposition, eliminating the visible shading at junction areas while maintaining material efficiency. This merging approach combines the benefits of multiple nozzles without their drawbacks.
Solution Approach 2:
The system performs preliminary positioning and calibration of nozzles to ensure proper spacing and alignment before glaze application begins. This preliminary action prevents shading issues at strip junctions by pre-establishing the correct geometric relationships between nozzles, allowing material-efficient multi-nozzle operation without surface quality defects.
4Productivity
If airless misting methodology is used, then glaze application speed is improved, but material waste increases due to suspension
Solution Approach 1:
The patent extracts the harmful suspension and waste generation characteristics of airless misting by replacing the misting mechanism with direct nozzle application. This extraction eliminates the problem of glaze particles remaining in suspension while maintaining high application speed through efficient nozzle design and positioning, directly addressing the material waste issue.
5Object-affected harmful factors
If vacuum system is added to manage glaze particles, then environmental control is improved, but device complexity increases
Solution Approach 1:
The patent converts the potential harm of glaze particle dispersion into a benefit by using the nozzle positioning and glaze flow control to ensure complete transfer of glaze to the substrate. The system design ensures that glaze is deposited directly where needed with minimal aerosol generation, eliminating the need for vacuum systems while maintaining environmental control.
