Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If ultrasound inspection method is used, then measurement precision of ceramic plate integrity is improved, but device complexity and ease of operation deteriorate due to requiring specialized equipment and expertise
Solution Approach 1:
The patent replaces the mechanical/physical ultrasound inspection system with an optical inspection system. The transparent fibre-reinforced composite layer acts as an optical indicator that visually reveals ceramic plate damage through light reflection changes, eliminating the need for complex ultrasound equipment and specialized expertise while maintaining damage detection capability.
Solution Approach 2:
The patent utilizes optical property changes in the transparent fibre-reinforced composite layer to indicate ceramic plate integrity. When the ceramic plate is damaged, the interface between the ceramic and composite layer changes, causing visible alterations in light reflection patterns through the transparent layer, enabling simple visual inspection.
2Measurement precision
If ultrasound inspection method is used, then measurement precision is improved, but ease of operation deteriorates due to requiring specialized expertise
Solution Approach 1:
The patent replaces the complex ultrasound operation requiring specialized expertise with simple visual inspection. The transparent composite layer provides direct optical visibility of ceramic plate damage through light reflection changes, allowing any user to perform inspection without training in ultrasound equipment operation.
3Measurement precision
If ultrasound inspection method is used, then measurement precision is improved, but loss of time deteriorates due to time required to perform control
Solution Approach 1:
The patent replaces time-consuming ultrasound inspection with immediate visual inspection. The transparent composite layer provides real-time visual feedback on ceramic plate integrity through light reflection patterns, eliminating the time required to set up and perform ultrasound scanning and analysis.
4Ease of operation
If transparent fibre-reinforced composite layer is used, then ease of operation is improved by enabling visual inspection, but manufacturing precision may deteriorate due to interface integrity requirements
Solution Approach 1:
The patent intentionally designs the transparent composite layer to change its optical properties based on interface integrity. The light reflection patterns are engineered to visibly indicate whether the ceramic-ceramic interface is intact or damaged, transforming a potential manufacturing challenge into a useful inspection feature.
Solution Approach 2:
The patent uses a composite structure of transparent fibre-reinforced composite material bonded to the ceramic plate. This composite layer serves dual purposes: providing structural reinforcement and acting as an optical indicator for damage detection, with the interface between materials designed to provide visual feedback on integrity.
