Integral RFID Tag Shaker Screen for Vibration Resilience
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Shale shakers and shaker screens face challenges with maintenance due to the vibratory nature of the equipment, leading to tag detachment and exposure to fluids, which affects separation efficiency and requires improved attachment methods for radio frequency identification tags (RFID) or surface acoustic wave tags (SAW) to enhance separation control and inventory management.
Innovation Solution
Integrating RFID or SAW tags with the screen frame or cross members, forming them as part of the whole structure to improve integrity and reduce exposure to fluids, and using reader antennae to adjust shaker operating variables based on tag information for optimal separation efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If RFID or SAW tags are attached to shaker screens using conventional attachment methods, then inventory management and separation control can be improved, but the tags detach due to vibratory equipment operation and exposure to fluids
Solution Approach 1:
The patent integrates the RFID or SAW tag directly into the shaker screen frame structure, merging the tagging function with the structural component. This eliminates separate attachment methods and ensures the tag remains reliably attached during vibratory operation and fluid exposure, while maintaining inventory management capabilities.
Solution Approach 2:
The tag is incorporated into the screen frame during manufacturing before the screen is deployed to the shaker. This preliminary integration ensures proper attachment and positioning from the start, preventing detachment issues that would arise from post-manufacturing attachment methods.
2Reliability
If tags are integrated into the screen frame structure, then tag detachment is prevented and fluid exposure is reduced, but manufacturing complexity increases
Solution Approach 1:
By combining the tag integration function with the existing screen frame manufacturing process, the patent avoids adding separate attachment steps. The tag becomes part of the frame structure through methods such as embedding, encapsulation, or direct attachment during frame fabrication, maintaining manufacturing efficiency while improving tag reliability.
3Productivity
If shaker operating variables are adjusted based on tag information, then separation efficiency is optimized, but system complexity and control requirements increase
Solution Approach 1:
The system uses RFID or SAW tags to provide feedback about screen identity, age, or condition to the control system. Based on this feedback, the control system automatically adjusts shaker operating variables such as vibration amplitude, frequency, or screen angle, optimizing separation efficiency without requiring complex manual intervention.
Solution Approach 2:
The shaker system automatically adjusts its own operating parameters based on information from the tags. This self-service capability eliminates the need for external monitoring and manual adjustment, reducing operational complexity while maintaining optimized separation performance.
