Molded Article Identification via Fixed and Amorphous Pattern Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for mold specification and individual identification of molded articles require additional processing steps, which can complicate the manufacturing process and affect the uniformity of the molded article's appearance, necessitating a method that does not perform additional surface processes on the molded article for individual identification.
Innovation Solution
An identification device that acquires and compares images of fixed and amorphous patterns formed on molded articles, using a processor to specify the mold by matching registered images stored in a storage unit, allowing for mold specification and individual identification without additional surface processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If additional surface processing is performed on molded articles for individual identification, then identification accuracy is improved, but manufacturing process complexity increases and appearance uniformity deteriorates
Solution Approach 1:
The invention performs preliminary action by forming an amorphous pattern on the molded article during the molding process itself, rather than adding it later. The amorphous pattern is created as part of the mold formation, specifically through the action of a core insert or gate, so that no additional surface processing is needed afterward. This resolves the contradiction by embedding the identification feature in the initial manufacturing step.
Solution Approach 2:
The invention merges the identification function with the structural formation function. The amorphous pattern is formed using the same molding process that creates the molded article's basic structure. By combining these two functions into a single molding operation, the process eliminates separate identification processing steps while maintaining both structural integrity and identification capability.
2Measurement precision
If additional surface processing is performed on molded articles for individual identification, then identification accuracy is improved, but appearance uniformity deteriorates
Solution Approach 1:
The amorphous pattern is formed preliminarily during the molding process itself, before the molded article leaves the mold. This ensures that the pattern becomes an integral part of the article's surface structure, eliminating the need for subsequent surface treatments that would compromise appearance uniformity. The pattern is embedded during formation rather than applied afterward.
Solution Approach 2:
The molding process itself serves the dual purpose of creating both the molded article's structure and its identification pattern. The core insert or gate structure automatically generates the amorphous pattern as part of the normal molding operation, without requiring external or additional processing. The system serves its own identification need through the inherent molding action.
3Measurement precision
If multiple images (fixed pattern and amorphous pattern) are captured and compared for identification, then identification accuracy is improved, but calculation load increases
Solution Approach 1:
The invention segments the identification task into two distinct pattern types: the fixed pattern (from mold surface) and the amorphous pattern (from core insert/gate). By separating these into distinct identifiable features, the system can process them independently and compare them systematically. This segmentation allows for more efficient pattern recognition and comparison algorithms, reducing overall computational complexity despite processing multiple images.

AI summary
An identification device configured to acquire a collation fixed image of a part of a region where a fixed pattern is formed, and a collation amorphous image of a part of a region where an amorphous pattern formed when the fixed pattern is formed on a region different from the region where the fixed pattern is formed, of a collation molded article; refer to a storage unit that stores, as a registered image in advance for a mold, a fixed image and an amorphous image pair of a part of a region where a fixed and an amorphous pattern are formed, of each of plural molded articles formed using the mold; specify a mold that forms the collation molded article using the registered fixed and collation fixed images, and identify whether the collation amorphous image matches the registered amorphous image of any of the registered images corresponding to the mold.
