Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If amplitude modulation dots are used to fix center distance and adjust dot size, then the visual effect and color shade simulation are improved, but the ability to accurately present image details deteriorates
Solution Approach 1:
The invention segments the dot pattern generation into two independent components: amplitude modulation for color/shade control and frequency modulation for detail control. This allows each component to optimize its function without compromising the other, resolving the contradiction between color simulation and detail presentation.
Solution Approach 2:
The invention creates a composite dot pattern that combines amplitude modulation dots and frequency modulation dots. This composite approach integrates the strengths of both techniques, enabling accurate color reproduction while simultaneously achieving high image detail fidelity.
2Adaptability or versatility
If frequency modulation dots are used to adjust center distance and maintain uniform dot size, then the pattern flexibility is improved, but the ease of software operation deteriorates
Solution Approach 1:
The invention introduces dynamic control parameters that allow users to adjust the balance between amplitude modulation and frequency modulation effects. This dynamic adjustment mechanism maintains pattern flexibility while simplifying software operation through intuitive parameter controls.
Solution Approach 2:
The invention creates a universal dot pattern generation system that can operate in multiple modes (amplitude modulation only, frequency modulation only, or combined). This multi-functionality allows the system to adapt to different design needs while maintaining consistent ease of operation through a unified interface.
3Manufacturing precision
If a large number of dots are used to achieve pattern details in frequency modulation, then the image detail presentation is improved, but the production feasibility deteriorates
Solution Approach 1:
The invention changes the controlling parameters from dot quantity to dot characteristics (size, spacing, distribution patterns). By controlling the amplitude and frequency parameters rather than simply increasing dot count, the system achieves high detail presentation while maintaining production feasibility through optimized parameter sets.
Solution Approach 2:
The invention applies partial frequency modulation effects combined with amplitude modulation, using only the necessary degree of frequency variation needed for detail presentation. This avoids the excessive action of using extremely large numbers of dots, thereby maintaining production feasibility while achieving sufficient detail fidelity.
4Manufacturing precision
If composite dots combining amplitude and frequency modulation are used, then the image detail presentation is improved, but the ease of software operation deteriorates
Solution Approach 1:
The invention implements feedback mechanisms that automatically adjust the balance between amplitude and frequency modulation based on image characteristics and user preferences. This feedback system maintains high image detail presentation while simplifying software operation by eliminating the need for manual balancing of multiple parameters.
Solution Approach 2:
The invention introduces an intermediary processing layer that translates user-friendly software controls into the complex combined amplitude-frequency modulation parameters. This intermediary automatically manages the complexity of composite dot generation while maintaining ease of operation through simplified user interface elements.
