Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing papermaking machines lack effective methods to determine the location of seal strip devices within suction rolls without physical access, as these components are sealed and not visible to operators, complicating maintenance and wear detection.
Innovation Solution
A system utilizing a seal strip location identification component, current monitoring circuit, and location circuit to determine the position of seal strip devices by measuring current through a passive electrical component, such as a resistor, and communicating this information via a common bus to a system coordinator circuit, allowing for automatic address assignment and location determination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If seal strip devices are installed inside suction rolls and sealed, then the reliability of the papermaking process is improved, but the difficulty of detecting and measuring the location of these devices increases
Solution Approach 1:
A location identification component is introduced as an intermediary element between the seal strip device and the external monitoring system. This component can be detected through the sealed structure without physical access, allowing location determination while maintaining the sealed configuration's reliability benefits
Solution Approach 2:
The patent replaces manual physical inspection methods with an electrical/electronic detection system. By using electrical components and circuits to detect and communicate location information, the system eliminates the need for physical access to sealed components while maintaining reliable process operation
2Manufacturing precision
If manual programming and operator training are required for seal strip location determination, then the manufacturing precision can be maintained, but the ease of operation deteriorates
Solution Approach 1:
The seal strip device performs self-identification of its location automatically. The location identification component and monitoring circuit enable the device to determine and communicate its own position without requiring external manual programming or operator intervention, thus maintaining precision while improving ease of operation
Solution Approach 2:
The location identification component is pre-configured during manufacturing with unique identifying characteristics. This preliminary action ensures that when the device is installed, its location can be automatically determined without requiring operators to perform complex programming tasks during installation or maintenance
