Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual handling of material webs is used, then device complexity is reduced, but productivity and reliability deteriorate due to time expenditure and lack of care in handling
Solution Approach 1:
The material roll is pre-oriented in a defined initial situation with the material web end positioned at a specific location before the splicing operation begins. This preliminary positioning enables the automated splicing apparatus to immediately engage with the material web without requiring manual intervention for orientation or positioning, thereby improving productivity while maintaining controlled device complexity
Solution Approach 2:
The automated splicing apparatus is designed to autonomously perform the entire splicing operation including receiving the oriented material roll, drawing in the material web, positioning it at the splicing location, and executing the connection without human intervention. The system serves itself by automatically completing tasks that would otherwise require manual handling, thus improving both productivity and reliability
2Loss of time
If manual removal of release liners is performed, then device complexity is reduced, but loss of time increases due to the tedious nature of the operation
Solution Approach 1:
The material roll is pre-oriented with the adhesive piece and its release liner positioned at a specific location before the splicing operation. This preliminary positioning enables the automated apparatus to immediately access and remove the release liner without manual intervention, reducing time loss while maintaining controlled device complexity
Solution Approach 2:
The manual mechanical action of peeling off the release liner is replaced by an automated mechanism within the splicing apparatus. The system automatically grasps, pulls, and removes the release liner from the adhesive piece, substituting human manual labor with automated mechanical action, thereby reducing time loss while the complexity is managed through integration into the existing splicing system
3Manufacturing precision
If manual orientation of material rolls is performed, then device complexity is reduced, but manufacturing precision deteriorates due to lack of exact positioning
Solution Approach 1:
The material roll is pre-oriented in a defined initial situation with precise positioning of the material web end at a specific location before the splicing operation begins. This preliminary precise orientation is achieved through automated positioning mechanisms that ensure exact alignment, thereby improving manufacturing precision while the complexity is managed through integration into the automated splicing system
Solution Approach 2:
The manual mechanical action of orienting and positioning the material roll is replaced by automated positioning mechanisms within the splicing apparatus. The system automatically orients the material roll to the defined initial situation and positions the material web end with precision, substituting human manual positioning with automated mechanical action, thereby improving manufacturing precision while managing device complexity through system integration
