Innovation Solution
A flexible coating unit with an interface for accommodating and energizing exchangeable joining agent processing means, allowing conversion of energy for different joining technologies, such as hot melt adhesive, laser-based, and hot gas-based methods, enabling the use of multiple technologies on a single machine.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate machines are provided for hot melt adhesive technology and zero-bond-line technology, then each technology can be implemented with dedicated equipment, but the overall system costs increase and processing options are limited
Solution Approach 1:
The coating unit is designed with a universal interface that can accommodate different joining agent processing means (hot melt adhesive application systems or laser-beam-specific systems). This allows a single machine to perform multiple coating technologies, thereby increasing adaptability while avoiding the need for separate dedicated machines for each technology
Solution Approach 2:
The coating unit is designed as a modular system where the joining agent processing means can be exchanged. The interface separates the common functional elements from the technology-specific elements, allowing independent replacement of processing means while maintaining the core unit structure
2Adaptability or versatility
If two separate machines are provided for different coating technologies, then processing variability is increased, but the device complexity and space requirements increase
Solution Approach 1:
The patent combines multiple joining agent processing means into a single coating unit. The interface allows different processing means (hot melt adhesive systems or laser systems) to be integrated into one machine, thereby providing processing variability while reducing space requirements compared to separate machines
3Adaptability or versatility
If exchangeable joining agent processing means are provided, then flexibility and future expansion are enabled, but the interface complexity increases
Solution Approach 1:
The interface is designed as a universal connection standard that can energize and accommodate different types of joining agent processing means. This universal design enables flexibility and future expansion while maintaining a standardized, manageable interface complexity through consistent connection and control protocols

Implementation Method 1
the energy conversion means for converting the energy provided via the interface to process a joining agent for joining the coating material to the workpiece surface to be coated. The joining agent can, for example, be a hot melt adhesive, in which case processing is then targeted, for example, at melting the hot melt adhesive
Implementation Method 2
the energy conversion means for converting the energy provided via the interface to process a joining agent for joining the coating material to the workpiece surface to be coated. Likewise, the energy conversion means of a hot melt adhesive bonding unit is capable, for example, of converting, on the joining agent processing means itself, the electrical energy provided via the interface into thermal energy for melting a bonding agent
Implementation Method 3
the joining agent can, for example, be a hot melt adhesive, in which case processing is then targeted, for example, at melting the hot melt adhesive
