Extraction Cell Magnetic Closure for Automated Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing extraction cells require significant manual effort for assembly and disassembly, and automated attachment or removal of closure arrangements is complex, making it difficult to achieve rapid and automated handling, especially for residual sample emptying and cleaning.
Innovation Solution
The use of adhesive arrangements, such as permanent-magnetic or silicone-based fasteners, to hold closure arrangements on the extraction body, allowing for linear movement and adjustable holding force, simplifying assembly, disassembly, and automated handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If screw connections are used to close the extraction body, then the closure arrangement can be securely attached, but manual effort is required for assembly or disassembly and automated attachment or removal becomes complex
Solution Approach 1:
The patent replaces the mechanical screw connection system with a magnetic field-based holding system. The permanent magnet arranged in the closure body interacts with the ferromagnetic material in the extraction body to provide secure attachment without requiring threading or manual screwing operations. This substitution eliminates complex mechanical fastening mechanisms while enabling simple linear movement for automated attachment and removal.
Solution Approach 2:
The patent extracts the rotational fastening function from the closure mechanism and replaces it with a linear magnetic holding system. By removing the screw thread component entirely, the design allows the closure body to be attached or removed through simple linear movement along the longitudinal center axis, significantly simplifying the operation and enabling automated handling.
2Extent of automation
If screw connections are used to close the extraction body, then the closure arrangement can be securely attached, but automated attachment or removal of the closure arrangements becomes complex or difficult to implement

3Reliability
If multiple components are used in the closure arrangement, then fluid-tight sealing can be achieved, but the number and complexity of components increases cleaning effort
Solution Approach 1:
The patent combines the sealing function with the closure body itself through an integrated design. The closure body includes a sealing surface that directly contacts the extraction body to create a fluid-tight seal, eliminating the need for separate sealing components. This merging of functions reduces the total number of parts while maintaining reliable sealing performance.
