Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If visual evaluation by user is used to determine machining surface problems, then the evaluation process is simple and intuitive, but the determination becomes subjective and inconsistent depending on user viewpoint and skill
Solution Approach 1:
The patent replaces the manual visual inspection process with an automated image processing system that captures machining surface images and analyzes them computationally. The system substitutes human subjective judgment with objective algorithmic evaluation, eliminating variability caused by different users while maintaining ease of operation through automated processing.
Solution Approach 2:
The patent introduces an intermediary image processing system that acts as a mediator between the machining surface and the evaluation process. This intermediary captures the surface through imaging, processes the visual information through algorithms, and provides consistent quantitative results, thereby resolving the contradiction between operational simplicity and measurement precision.
2Device complexity
If subjective visual evaluation is used, then no complex equipment is needed, but it is difficult to numerically determine whether machining satisfies required accuracy
Solution Approach 1:
The patent replaces subjective visual assessment with automated image processing algorithms that quantitatively analyze surface features. The system captures images and uses computational methods to extract numerical metrics about machining accuracy, enabling objective verification against required standards without requiring complex physical measurement equipment.
Solution Approach 2:
The patent transforms visual surface information into quantitative parameters through image processing. By converting visual data into numerical metrics that can be compared against accuracy requirements, the system enables precise manufacturing verification while maintaining relatively simple equipment requirements.
3Adaptability or versatility
If evaluation depends on user skill and display settings, then the process is flexible and adaptable, but the results vary and problematic locations may be missed
Solution Approach 1:
The patent replaces human-dependent evaluation with an automated system that applies consistent processing algorithms to all images. The system eliminates variability introduced by different users and display settings while maintaining flexibility through programmable analysis parameters and adaptable image processing routines.
Solution Approach 2:
The patent establishes predetermined evaluation criteria and processing parameters before the actual evaluation occurs. By pre-configuring the analysis methodology and consistency standards, the system ensures reliable and repeatable results while maintaining adaptability through adjustable parameters for different machining scenarios.
