Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed glue dam sealing element is used on the roller, then the structure is simple, but the sealing effect is insufficient and wear is high
Solution Approach 1:
The patent applies the dynamics principle by making the glue dam sealing element pivotable rather than fixed. The sealing element can rotate about a pivot axis, allowing it to dynamically adapt to the roller surface and maintain optimal sealing contact. This dynamic capability improves the sealing effect while the pivot mechanism remains relatively simple in structure.
2Duration of action of stationary object
If a fixed sealing element is used, then the structure is simple, but the wear distribution is uneven and service life is reduced
Solution Approach 1:
The pivotable design allows the sealing element to dynamically adjust its position and orientation during operation. This dynamic adaptation ensures more uniform wear distribution across the sealing element surface, extending its service life. The mechanism remains mechanically simple with a straightforward pivot connection.
3Adaptability or versatility
If a non-pivotable sealing element is used, then the handling is straightforward, but the adaptation to the roller is poor
Solution Approach 1:
The sealing element is designed to be pivotable about a pivot axis that is offset from its center of gravity. This creates a self-adjusting mechanism where the element automatically adapts to the roller surface through controlled rotation, improving adaptability while maintaining ease of installation and operation.
Solution Approach 2:
The offset pivot axis design enables the sealing element to self-adjust and self-adapt to the roller surface during operation. The element automatically positions itself optimally without requiring external adjustment mechanisms, combining improved adaptability with operational simplicity.
4Reliability
If urging force is not applied, then the structure is simple, but the sealing pressure is insufficient
Solution Approach 1:
The patent introduces an urging mechanism that applies controlled force to the sealing element, changing the pressure parameter to ensure adequate sealing. The urging force can be adjusted to optimize sealing pressure while maintaining a relatively simple mechanical structure.
