Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If liquid developer is used for plate washing, then the black film can be cleaned off the plate, but the washing effect becomes inconsistent due to temperature loss from water flow and environmental harm is caused
Solution Approach 1:
The patent replaces the liquid chemical washing system with a mechanical adhesion system. A washing material (solid material) is pressed against the plate surface through a pressing mechanism, and the black film is removed through mechanical adhesion and friction rather than chemical dissolution. This substitution eliminates the need for liquid developers, preventing environmental contamination and odor issues while providing more consistent washing results through controlled mechanical pressure and motion.
Solution Approach 2:
The patent changes the physical state of the washing medium from liquid to solid. By using a solid washing material with specific friction characteristics and pressing it against the plate with controlled force, the system achieves consistent washing效果 without the temperature instability and environmental problems associated with liquid developers. The solid material's properties (friction coefficient, hardness, surface texture) are optimized to maintain effective black film removal.
2Object-affected harmful factors
If non-liquid plate washing method is adopted, then environmental harm is reduced, but the flatness of the plate washing material leads to inconsistent washing effects
Solution Approach 1:
The patent introduces dynamic elements to the solid washing system. The washing material is fed through a mechanism that maintains continuous contact with the rotating plate, and the pressing force is dynamically adjusted to ensure uniform pressure distribution. The washing material itself may have flexible properties that allow it to conform to the plate surface, ensuring consistent flatness and contact during the washing process, thereby achieving both environmental protection and washing consistency.
Solution Approach 2:
The washing material is designed as a flexible thin film or sheet that can conform to the plate surface. This flexibility ensures uniform contact across the entire plate area, maintaining consistent flatness during washing. The material's ability to adapt to surface variations while remaining solid prevents the inconsistency problems that would arise from rigid washing elements, thus resolving the contradiction between environmental protection and washing precision.
3Manufacturing precision
If the plate washing material is pressed against the plate, then the contact area increases and cleaning efficacy improves, but the material flatness may be affected
Solution Approach 1:
The patent applies preliminary action by pre-flattening or pre-conditioning the washing material before it contacts the plate. The material is fed through rollers or a flattening mechanism that ensures it is uniformly flat and free of wrinkles or deformations before reaching the pressing zone. This preliminary preparation maintains material flatness even under pressing conditions, allowing increased contact area and improved cleaning efficacy without sacrificing shape integrity.
Solution Approach 2:
The patent merges the flattening function with the pressing function in an integrated mechanism. The same pressing mechanism that applies force to remove the black film also serves to maintain and restore material flatness during continuous operation. This combination ensures that the material remains flat and maintains optimal contact with the plate throughout the washing process, achieving both high cleaning efficacy and shape preservation simultaneously.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system enhances cleaning efficacy by correcting material flatness, increasing contact area, and maintaining temperature, resulting in stable and precise plate washing without liquid developers, reducing environmental impact.
