Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The application of coating media in industrial processes, particularly in high-voltage energy storage systems, faces challenges due to environmental conditions and the need for precise, localized application to avoid functional impairments such as detachment and short circuits, necessitating the use of adhesion promoters that must not be applied outside specific areas.
Innovation Solution
A coating device with a detection system, such as a laser-based triangulation or profile sensor, to detect geometric properties of components and control a movable coating nozzle to apply the medium selectively based on predetermined criteria, ensuring accurate application only to intended areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If an adhesion promoter is applied to prevent foam detachment from cell shoulders, then the bonding strength is improved, but the risk of short circuits increases if the coating is applied outside the intended areas
Solution Approach 1:
The patent applies local quality by using a detection device (camera) to identify the precise location of cell shoulders and controlling the coating nozzle to apply adhesion promoter only to those specific areas. This spatially selective application ensures that the coating is applied locally where needed (on cell shoulders) while avoiding sensitive areas, thus maintaining both bonding strength and electrical safety.
Solution Approach 2:
The patent implements feedback by using a detection device to capture the geometric properties and position of cell shoulders in real-time, then using this information to dynamically control the coating nozzle's movement and application. The system continuously monitors the component geometry and adjusts the coating application accordingly, ensuring precise application only where required and preventing misapplication that could cause short circuits.
2Reliability
If the coating application is made highly selective to avoid sensitive areas, then the safety is improved, but the manufacturing complexity increases
Solution Approach 1:
The patent applies universality by integrating multiple functions into a single coordinated system: the detection device (camera) serves both to identify cell shoulder locations and to guide the coating nozzle, while the control unit coordinates both the detection and coating functions. This multi-functional integration achieves precise selective application without requiring separate complex systems for detection and application, thereby managing manufacturing complexity while maintaining safety.
Solution Approach 2:
The patent uses an intermediary approach by introducing a control unit that acts as a mediator between the detection device and the coating nozzle. The control unit processes the geometric data from the detection device and translates it into precise motion control for the coating nozzle, enabling selective application without direct mechanical complexity in the coating mechanism itself. This intermediary control layer simplifies the overall system architecture while achieving high precision.
3Manufacturing precision
If the coating nozzle is made movable to adapt to component geometry, then the application precision is improved, but the device complexity increases
Solution Approach 1:
The patent replaces complex mechanical positioning systems with an optical detection and digital control system. Instead of using mechanically complex adjustable nozzles or fixtures, the system uses a camera to detect component geometry and a control unit to calculate and guide the nozzle position. This substitution of mechanical systems with optical and digital systems achieves high application precision while actually reducing mechanical device complexity.
Solution Approach 2:
The patent applies dynamics by making the coating nozzle position dynamically adjustable based on real-time detection of component geometry. The system can adapt to variations in cell shoulder positions and orientations by dynamically controlling the nozzle's movement and orientation. This dynamic adaptability achieves high precision application across different component configurations without requiring a completely different nozzle for each case, thereby managing device complexity.
