Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If simple image processing functions are used, then device complexity is reduced, but image processing capability and user satisfaction deteriorate
Solution Approach 1:
The system automatically corrects outline shapes by detecting user intent and applying corrections without requiring manual adjustment. The controller identifies rough outlines drawn by users and autonomously refines them into smooth, precise cropping boundaries, allowing the device to serve itself in enhancing image processing capability without proportionally increasing operational complexity
Solution Approach 2:
The system performs preliminary outline correction before the actual cropping operation. By pre-processing the rough outline into a refined shape, the system prepares the cropping boundary in advance, enabling sophisticated image processing capability while keeping the user interaction simple and the overall device complexity manageable
2Ease of operation
If manual outline drawing is used for cropping, then ease of operation is improved, but manufacturing precision of the crop outline deteriorates
Solution Approach 1:
The system introduces an intermediary processing step between manual outline drawing and final cropping. The controller acts as a mediator that receives rough user-drawn outlines and transforms them into precise cropping boundaries through automatic correction algorithms, thereby maintaining ease of operation while achieving high manufacturing precision in the crop outline
Solution Approach 2:
The system replaces the mechanical precision requirement (needing perfectly precise manual drawing) with an automated correction mechanism. Instead of relying on user precision, the system uses computational algorithms to detect and refine the outline, substituting mechanical precision needs with software-based precision enhancement
