Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The process of changing chromatography cartridges in existing systems is laborious and time-consuming due to the need for clamping and sealing, which complicates the interchanging of cartridges with different thread sizes and configurations.
Innovation Solution
A chromatography system with a detachable cartridge adapter that uses interchangeable coupling components with threads of varying sizes, secured by a coupling retainer with a keyway mechanism, allowing for quick interchanging of cartridges by aligning parallel sides and using spring elements for secure sealing to prevent leaks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cartridges are clamped and sealed to the chromatography system, then reliable sealing is achieved, but the cartridge changing process becomes laborious and time-consuming
Solution Approach 1:
The system is divided into modular components: a reusable coupling retainer with keyway mechanism, interchangeable coupling components with different thread configurations, and cartridges. This segmentation allows the sealing mechanism to remain fixed while only the coupling component needs to be changed, reducing overall cartridge changing time while maintaining sealing reliability through the consistent keyway engagement.
Solution Approach 2:
The coupling components are pre-configured with specific thread sizes and keyway alignments. The keyway mechanism is pre-designed to automatically align and secure the coupling component when inserted, eliminating the need for manual alignment and sealing adjustments during cartridge changes. This preliminary preparation enables quick interchange while ensuring reliable sealing.
2Strength
If traditional clamping mechanisms are used to secure cartridges, then secure attachment is achieved, but the interchange process becomes complex and slow
Solution Approach 1:
The coupling retainer features a dynamic keyway mechanism that transitions from an unlocked state during insertion to a locked state during operation. The keyway allows the coupling component to be quickly inserted and rotated into position, where it automatically engages and locks securely. This dynamic mechanism provides strong attachment during use while enabling rapid interchange when needed.
3Adaptability or versatility
If multiple thread configurations are supported, then versatility is improved, but device complexity increases
Solution Approach 1:
The coupling retainer with keyway mechanism serves as a universal interface that can accommodate multiple thread configurations through interchangeable coupling components. The retainer itself remains unchanged, providing a standardized mounting interface, while only the coupling components need to be swapped to support different thread sizes and types. This universal approach enables versatility without proportionally increasing overall system complexity.

AI summary
A chromatography system has a cartridge adapter that is detachably attachable to enable a chromatography cartridge to be quickly interchanged. Chromatography cartridges are configured with threads for coupling to a corresponding interchangeable coupling component having matching threads. The interchangeable coupling component may be secured to the chromatography system by a coupling retainer. A coupling retainer may have a keyway that is configured for quick interchanging of the interchangeable coupling components. The interchangeable coupling component may have a pair of parallel sides that align with a slot of the keyway to secure the interchangeable coupling components to the coupling retainer. An inlet nipple of the chromatography cartridge may extend through an opening in the coupling components and couple to an inlet conduit for sample gas. Analyte gas may flow back to the chromatography system for detection and collection.
