Method for marking references on a flat article and related system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for marking references on flat articles, such as leather, are prone to inaccuracy due to operator dependence, require excessive manual effort, and are inefficient, especially when dealing with complex or thick materials, leading to reduced precision and productivity.
Innovation Solution
An automated system that uses a model with through-openings to detect and replicate the peripheral profiles of both the model and the article, allowing for precise and contactless marking of references, eliminating the need for manual alignment and enabling rapid marking of multiple references with high precision and repeatability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual marking method using cardboard model and marker pen is used, then the marking process is simple and equipment-free, but the marking precision deteriorates due to operator experience dependence and inability to maintain perpendicular pressure
Solution Approach 1:
The patent replaces the manual mechanical marking system (cardboard model + marker pen) with an automated marking system that uses a camera to detect the model's through-openings and a marking device to automatically mark references. This substitution eliminates operator-dependent precision issues while maintaining the simplicity of the overall process.
Solution Approach 2:
The system enables self-service marking by automatically detecting the model's through-openings and generating reference marks without requiring operator intervention for each marking action. The automated system performs alignment and marking based on detected features, making the process independent of operator skill level.
2Device complexity
If manual alignment and marking of multiple references is performed, then the equipment requirement is minimal, but the working time increases significantly leading to reduced productivity
Solution Approach 1:
The patent replaces manual alignment and marking operations with an automated system that uses a camera to detect through-openings and automatically positions and marks references. This substitution dramatically reduces working time while the system remains relatively simple in structure.
Solution Approach 2:
The system performs preliminary detection of the model's through-openings and pre-calculates the positions of multiple references before executing the marking operation. This allows rapid sequential marking of multiple references without repeated manual alignment, significantly improving productivity.
3Quantity of substance
If excessive pressure is applied by marker pen on thick or rough leather, then the marking becomes visible, but the marking precision deteriorates and creates difficulty in eliminating imprecise markings
Solution Approach 1:
The patent replaces the mechanical marker pen system with an automated marking device that can precisely control marking parameters. This substitution allows consistent marking quality without the pressure control issues inherent in manual operation, particularly on difficult materials like thick or rough leather.
Solution Approach 2:
The system uses camera detection to verify the model's position and orientation before marking, providing feedback that ensures precise alignment. This feedback mechanism prevents imprecise markings from occurring in the first place, eliminating the need for pressure adjustment tricks.
4Loss of time
If the model is not superposed exactly on the flat article, then the alignment process is faster, but the marking functionality deteriorates due to incorrect reference positions
Solution Approach 1:
The system performs self-alignment by automatically detecting the model's through-openings and calculating the correct positions of references relative to the flat article. This eliminates the need for manual superposition and alignment by the operator, achieving both speed and precision simultaneously.
Solution Approach 2:
The patent replaces manual visual alignment with an automated optical detection system that uses a camera to detect through-openings and computationally determines the correct reference positions. This substitution achieves precise positioning without requiring time-consuming manual superposition.
