Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional machining methods are used with separate storage of machining information and workpiece images, then device complexity is reduced, but information accessibility deteriorates making it hard to link optical features to machining programs
Solution Approach 1:
The patent merges machining information and workpiece image information into a unified link information structure. The link information generation unit combines machining program data, machine state information, and optical feature data from workpiece images into integrated link information that associates specific image areas with corresponding machining program blocks and machine parameters, enabling comprehensive information access without increasing operational complexity
Solution Approach 2:
The patent introduces link information as an intermediary data structure that bridges machining information and workpiece image information. This link information acts as a mediator containing both machining program data and optical feature data, allowing users to access either type of information through the other without direct complex linking mechanisms
2Loss of information
If detailed machining information is stored for each workpiece area, then information completeness is improved, but data processing complexity increases
Solution Approach 1:
The patent segments machining information and workpiece image information into distinct but linkable components. Machining information is divided into program blocks with specific execution positions, while workpiece images are divided into image areas with optical features. The link information segments and associates corresponding elements from both datasets, enabling complete information storage with structured, manageable data organization
Solution Approach 2:
The patent applies local quality by associating specific machining information with specific image areas rather than storing all information globally. Each link information record contains machining program data and optical feature data localized to corresponding workpiece areas, allowing efficient retrieval and processing of only relevant information subsets
