Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual setting is used for faceting, then the operator can perform the faceting operation, but it is difficult to estimate the shape of the lens after faceting and accurately perform the setting, leading to poor quality and requiring time and labor
Solution Approach 1:
The patent replaces manual mechanical setting operations with an automated image processing system. The control portion automatically acquires images of the lens, detects facet lines through image processing algorithms, and generates faceting control data without manual intervention. This substitution eliminates the difficulty of manual shape estimation while maintaining high precision through automated detection algorithms.
Solution Approach 2:
The patent uses image copying and processing to represent the lens geometry. By capturing images of the lens and creating digital representations through image processing, the system can analyze and determine facet lines without physical manual measurement. The copied image data serves as the basis for automated faceting control, improving both accuracy and ease of operation.
2Productivity
If manual setting is used for faceting, then the operator can perform the operation, but it takes time and labor to set the faceting
Solution Approach 1:
The patent replaces time-consuming manual setting operations with automated image processing. The control portion automatically captures lens images, processes them to detect facet lines, and generates control data without human intervention. This automation dramatically reduces the time and labor required for faceting setup while increasing productivity through rapid automated processing.
Solution Approach 2:
The system performs self-service by automatically acquiring its own control data. The control portion independently captures images, processes them through image processing algorithms, and generates faceting control data without requiring external manual input. This self-service capability eliminates the time and labor previously needed for manual setting operations.
3Reliability
If manual setting is used for faceting, then the operator can perform the operation, but the quality of the lens after faceting may not be good due to difficulty in estimating shape
Solution Approach 1:
The patent replaces unreliable manual shape estimation with automated image processing. The control portion objectively detects facet lines from lens images using processing algorithms, eliminating human error and subjectivity. This substitution ensures consistent, reliable lens quality by base faceting control on precise automated detection rather than manual judgment.
Solution Approach 2:
The patent creates accurate digital copies of the lens geometry through image capture and processing. These copied image representations provide an objective basis for determining facet lines, ensuring consistent and reliable results. The digital copy allows for precise measurement and analysis that maintains quality consistency across different lenses and operators.
