Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional cleaning methods are used to clean glass surfaces before decoration, then the cleaning process is simple and quick, but impurities and protective coatings are not effectively removed, leading to uneven ink distribution and decoration flaws
Solution Approach 1:
The invention changes the physical parameters of the cleaning process by using a heating device to emit heat flow that impinges on the glass surface. This thermal energy transforms the state of impurities and protective coatings, enabling effective removal without complex mechanical cleaning systems, thus achieving both high cleanliness and productivity
Solution Approach 2:
The invention replaces traditional mechanical cleaning methods with a thermal field approach. The heating device generates heat flow that acts on the glass surface to remove impurities and coatings, substituting mechanical contact with thermal energy transfer, thereby maintaining high productivity while achieving superior cleaning precision
2Manufacturing precision
If protective coating is removed from glass articles before hardening, then the glass surface is clean for decoration, but time is wasted in the removal process
Solution Approach 1:
The heating device performs preliminary thermal treatment on the glass surface that simultaneously achieves coating removal and surface preparation for decoration. This preliminary action eliminates the need for separate coating removal steps, reducing time loss while ensuring surface cleanliness
Solution Approach 2:
The invention merges the coating removal function with the surface cleaning function into a single thermal processing step. The heat flow from the heating device accomplishes both tasks concurrently, eliminating sequential operations and reducing overall processing time
3Manufacturing precision
If protective coating is subjected to heat treatment in the hardening furnace, then coating removal occurs, but undesired residues accumulate in the furnace impairing cleanliness
Solution Approach 1:
The invention extracts the coating removal process from the hardening furnace and relocates it to a separate heating device positioned before the furnace. This extraction prevents coating residues from entering and contaminating the hardening furnace, eliminating the harmful effect of residue accumulation while maintaining effective coating removal
Solution Approach 2:
The heating device acts as an intermediary between the glass article and the hardening furnace. It performs the coating removal function in advance, serving as a mediator that protects the hardening furnace from direct exposure to coating residues, thereby preventing pollution while achieving the desired coating removal
4Manufacturing precision
If multiple cleaning and preparation steps are performed on glass articles, then surface cleanliness is improved, but the process complexity and cost increase
Solution Approach 1:
The heating device is designed to perform multiple functions simultaneously: it removes protective coatings, cleans impurities from the glass surface, and prepares the surface for decoration. This multi-functionality eliminates the need for multiple separate processing steps and devices, reducing overall system complexity while maintaining high surface cleanliness
Solution Approach 2:
The invention merges coating removal, surface cleaning, and surface preparation functions into a single integrated thermal processing step using the heating device. This consolidation reduces the number of processing steps and associated equipment, lowering device complexity and operational costs while achieving the desired surface quality
