Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The dyeing of aluminum products often results in inaccurate and unpredictable gradient colors due to reliance on human expertise, leading to inconsistent and poor dyeing outcomes, especially when multiple dyeing processes are required to achieve desired color gradients.
Innovation Solution
A method is developed to establish a dyeing model using historical data of dyeing times and color values, which trains an initial model to determine the required dyeing time based on the desired color value, thereby eliminating manual judgment and ensuring precise dyeing processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If expert's experience is used to control the dyeing process, then the dyeing process can be performed with simple equipment and operations, but the dyeing time is not accurate enough and the results are inconsistent
Solution Approach 1:
The patent replaces the mechanical system of manual expert judgment with an automated machine learning model. The model takes parameters such as anodizing voltage, anodizing time, and workpiece material as inputs and automatically outputs precise dyeing time predictions, eliminating the need for human experts to manually determine dyeing times based on experience.
Solution Approach 2:
The patent implements a self-service system where the dyeing process automatically determines optimal parameters through the machine learning model. The system self-learns from historical dyeing data and automatically predicts dyeing times without requiring continuous human intervention or expert involvement in each dyeing operation.
2Reliability
If manual judgment is used to determine dyeing time, then the equipment and operation remain simple, but the dyeing results are prone to human misjudgment and inconsistency
Solution Approach 1:
The patent implements a feedback mechanism where the machine learning model is trained on historical dyeing data that includes actual dyeing times and resulting color values. The model continuously learns from past performance and adjusts its predictions to improve accuracy, creating a closed-loop system that enhances reliability through data-driven optimization.
Solution Approach 2:
The patent transforms the dyeing process from manual parameter selection to automated parameter prediction by changing the state of the determination system from human-based to algorithm-based. The model processes multiple parameters simultaneously (anodizing conditions, material properties, color targets) to generate optimized dyeing time predictions that are more reliable than manual judgment.
3Manufacturing precision
If multiple dyeing processes are performed to achieve gradient colors, then the desired color effects can be obtained, but the process time increases and productivity decreases
Solution Approach 1:
The patent applies preliminary action by using the machine learning model to predict the optimal second dyeing time in advance, before the actual dyeing process begins. The model calculates the precise duration needed to achieve the desired color gradient, allowing the process to proceed efficiently without trial-and-error adjustments during the dyeing operation.
Solution Approach 2:
The patent introduces dynamics by enabling flexible adjustment of dyeing parameters based on real-time conditions. The machine learning model can adaptively determine dyeing times based on varying inputs such as different workpiece materials, anodizing conditions, and target color values, optimizing each dyeing operation dynamically rather than using fixed time schedules.

AI summary
The present application discloses an establishing method for establishing a dyeing model, a dyeing method, a device, and a storage medium which are applied to the dyeing technology field. The establishing method includes: obtaining historical data of dyeing a workpiece, the historical data includes historical dyeing time of the workpiece and historical color value of the workpiece after dyeing; and obtaining the dyeing model by training an initial model based on the historical data. The dyeing model is established using the historical data, and can establish a relationship between the dyeing time and the color value of the workpiece after dyeing. Based on the dyeing model, the dyeing time required for the workpiece can be determined according to a color value of the workpiece after dyeing. A precise dyeing process can be realized by determining the dyeing time using the dyeing model instead of determining the dyeing time manually.
