Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed image processing functions are provided for low vision mode, then basic accessibility is achieved, but flexibility and adaptability to user preferences are insufficient
Solution Approach 1:
The patent implements dynamic image processing by allowing users to adjust multiple parameters (edge thickness, brightness, contrast, sharpness, color) in real-time based on their preferences. The system transitions from fixed processing functions to dynamically adjustable parameters, enabling adaptability without requiring complex control systems through intuitive sliders and preset options.
Solution Approach 2:
The patent applies parameter changes by providing multiple adjustable parameters for image processing including edge thickness, brightness, contrast, sharpness, and color saturation. Each parameter can be independently adjusted to suit user preferences, transforming the rigid fixed-function approach into a flexible parameter-based system that adapts to individual needs.
2Manufacturing precision
If multiple image processing parameters are adjusted, then image quality and visibility are improved, but processing time and computational load increase
Solution Approach 1:
The patent implements preliminary action by providing preset configurations (e.g., strong, medium, weak enhancement levels) that pre-combine multiple parameter adjustments. Users can immediately apply comprehensive image processing with optimal quality by selecting presets, avoiding the time-consuming process of manually adjusting each parameter while still achieving high processing quality.
Solution Approach 2:
The patent applies partial action by allowing users to selectively adjust only the parameters they need rather than processing all parameters simultaneously. Users can focus on critical parameters like edge thickness and brightness while leaving other parameters at default values, reducing processing time while maintaining sufficient image quality for low vision needs.
