Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wet chemical cleaning and mechanical blasting are used for surface treatment, then cleaning effectiveness and adhesion improvement are achieved, but hazardous substances are consumed and disposal costs increase
Solution Approach 1:
The patent replaces wet chemical cleaning and mechanical blasting with laser irradiation. The laser beam directly removes contaminants through ablation without requiring chemical agents or mechanical consumables, thereby eliminating hazardous substance consumption while maintaining cleaning effectiveness.
Solution Approach 2:
The patent changes the physical state and properties of the laser beam parameters (wavelength, power, pulse duration) to optimize surface treatment. By adjusting these parameters, the laser can effectively clean and prepare surfaces without the need for hazardous chemicals or mechanical consumables.
2Productivity
If collective laser treatment is applied to mass-produced bulk materials, then costs and resource usage are reduced, but uniform surface properties must be achieved
Solution Approach 1:
The patent introduces dynamic movement of the bulk material through mixing during laser irradiation. This ensures that all surfaces are statistically exposed to the laser beam, achieving uniform surface properties across the entire batch while maintaining cost efficiency through collective treatment.
Solution Approach 2:
The patent employs periodic mixing and redistribution of the bulk material during laser treatment. This periodic action ensures that all surfaces receive comparable laser exposure over time, achieving uniform surface properties while treating the entire batch collectively.
3Reliability
If traditional cleaning methods are used for mass-produced bulk materials, then surface contaminants are removed, but excessive consumables and hazardous chemicals are required
Solution Approach 1:
The patent replaces mechanical blasting and wet chemical cleaning with laser irradiation. This substitution eliminates the need for blasting media, chemicals, and other consumables, achieving contaminant removal without excessive substance loss.
Solution Approach 2:
The laser beam performs the cleaning function directly through photothermal and photomechanical effects, without requiring external consumables. The energy from the laser itself is sufficient to remove contaminants, making the process self-sufficient and free from consumable usage.
