Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods struggle to accurately mark and track defects on electrodes during secondary battery manufacturing, making it difficult to identify and analyze the cause of defects in finished battery products, leading to potential safety issues.
Innovation Solution
A system and method for generating a roll map using an inspection and measurement device to track and display inspected and measured data on a simulated electrode, including coordinate values and defect data, allowing for precise identification and tracking of defects throughout the manufacturing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual marking or tagging is used to identify defects on electrodes, then defect identification is possible, but the exact location of defects becomes difficult to determine and track
Solution Approach 1:
The patent creates a virtual copy of the electrode in the form of a roll map that preserves all spatial information. Instead of physically marking the electrode, the system generates a digital representation that can be annotated and tracked throughout the manufacturing process, maintaining precise location data without interfering with the physical electrode.
Solution Approach 2:
The patent transitions from two-dimensional physical marking on the electrode surface to a three-dimensional virtual space that includes temporal dimension. The roll map system captures defect locations in a virtual coordinate system that can be tracked across multiple manufacturing stages, adding the dimension of time and process stage to the location tracking.
2Loss of information
If physical markings are placed on electrodes during manufacturing, then defect information can be recorded, but the markings are removed or disappear during subsequent manufacturing processes
Solution Approach 1:
The system creates a persistent digital copy of defect information in the roll map that survives throughout the entire manufacturing process. Unlike physical markings that are removed during handling and assembly, the virtual markings in the roll map system remain intact and can be tracked from electrode manufacturing through battery assembly and activation.
Solution Approach 2:
The roll map system acts as an intermediary between the physical electrode and the defect tracking system. Rather than marking the electrode directly, the system projects defect information onto a virtual representation, allowing defect tracking without physical contact that would lead to marking loss during subsequent processes.
3Loss of information
If traditional marking methods are used on finished battery products, then defect history can be partially identified, but comprehensive manufacturing process information cannot be determined
Solution Approach 1:
The roll map system serves multiple functions within a single integrated platform: it tracks defect locations, records manufacturing process parameters, monitors electrode movement through the production line, and maintains correlation data across different manufacturing stages. This multi-functional approach eliminates the need for separate tracking systems for each function.
Solution Approach 2:
The patent combines defect tracking, process monitoring, and product identification into a single integrated roll map system. By merging these previously separate functions into one unified virtual representation, the system achieves comprehensive information tracking without proportionally increasing complexity.
