Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple evaluation indices are used to assess tool path quality, then the comprehensiveness of evaluation is improved, but the complexity of determining which items require optimization increases
Solution Approach 1:
The patent introduces a determination unit as an intermediary component that receives multiple evaluation indices from the analysis/evaluation unit and processes them to identify which specific evaluation items require optimization. This intermediary structure simplifies the overall system by centralizing the complex determination logic in a dedicated component, making the system manageable despite handling multiple evaluation criteria.
Solution Approach 2:
The system implements a feedback mechanism where the determination unit analyzes evaluation results and provides guidance back to the path adjustment unit. The determination unit compares actual evaluation values against reference values and feeds back specific information about which evaluation items need optimization, enabling targeted adjustments rather than comprehensive re-optimization of all parameters.
2Manufacturing precision
If all evaluation items are optimized, then the overall tool path quality is improved, but the machining time and computational resources increase
Solution Approach 1:
The patent extracts and identifies only the specific evaluation items that require optimization from the complete set of evaluation indices. The determination unit compares actual values against reference values and extracts only those items with significant deviations, allowing the system to focus optimization efforts on critical parameters rather than all parameters, thereby reducing computational overhead and machining time.
Solution Approach 2:
Instead of optimizing all evaluation items comprehensively, the system applies partial optimization by selecting only the necessary evaluation items that require adjustment. This partial action approach achieves sufficient tool path quality improvement without the excessive computational resources and time that would be required to optimize every evaluation parameter.
3Manufacturing precision
If the tool path is adjusted based on comprehensive evaluation, then the machining accuracy is improved, but the complexity of path adjustment increases
Solution Approach 1:
The patent applies local quality by making path adjustments specific to particular evaluation items that require optimization rather than applying uniform adjustments across the entire tool path. The path adjustment unit receives targeted guidance from the determination unit about which specific aspects need improvement and applies localized adjustments only to those areas, simplifying the overall adjustment process while maintaining high machining accuracy.

AI summary
An optimization device includes a tool path, an analysis/evaluation unit for inputting one or more evaluation indices each including an evaluation item and weighting, analyzing and evaluating the tool path for each evaluation item, and outputting one or more analysis/evaluation results, and a normalization unit that normalizes the analysis/evaluation results considering the weighting, and outputs one or more normalized analysis/evaluation results. The optimization device also includes a determination unit for inputting a determination criterion, and determining the necessity of path adjustment based on the determination criterion and the normalized analysis/evaluation results such that, when a path adjustment is required, a determination result is outputted including either the normalized analysis/evaluation results or an item requiring adjustment selected from the evaluation items, and a path adjustment unit that performs an adjustment of the tool path based on the determination result, and outputs a path adjustment result including the adjusted tool path.
