Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing manufacturing methods lack a fixed and effective detection standard for determining the state of manufacturing elements, relying on subjective visual inspections which are inconsistent and unreliable.
Innovation Solution
A manufacturing method that involves pressing a manufacturing element on a detection element to generate indentation patterns, converting these patterns into image data, calculating image feature values, and comparing them against established thresholds to determine the pressure distribution and state of the element, providing a standardized assessment without relying on visual inspection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If visual inspection is used to determine the state of manufacturing elements, then the detection process is simple and quick, but the detection standard becomes subjective and inconsistent
Solution Approach 1:
The patent replaces the mechanical/visual inspection system with an optical detection system. A detection element captures indentation patterns created by manufacturing elements, and an image processing system automatically analyzes these patterns to generate quantitative detection results, eliminating subjective human judgment while maintaining operational simplicity
Solution Approach 2:
The patent introduces a detection element as an intermediary between the manufacturing element and the inspector. This detection element records indentation patterns that serve as objective evidence, allowing the actual state of the manufacturing element to be reflected accurately without relying on the inspector's subjective vision
2Device complexity
If subjective visual inspection is used, then no complex detection equipment is needed, but the detection reliability and accuracy decrease
Solution Approach 1:
The patent creates a visual copy of the manufacturing element's state through indentation patterns on the detection element. This copy captures the essential information about the manufacturing element's condition, allowing for reliable analysis without needing to directly measure or inspect the original manufacturing element with complex equipment
Solution Approach 2:
The patent transforms the physical state of the manufacturing element (pressure distribution, flatness) into a different parameter form (indentation pattern, image data). This parameter transformation enables reliable detection using simple imaging technology rather than requiring complex direct measurement of the original physical parameters
