Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Chromatography systems face challenges in quickly, easily, and reliably coupling two chromatography columns due to issues with threaded connections, such as over-tightening, under-tightening, leaks, and alignment problems, which require special tools and additional time.
Innovation Solution
A clamp system with a non-movable seal and a movable coupler, allowing for the secure pressing of two chromatography columns on opposite sides of a compression seal coupler, ensuring fluid communication through the columns, and featuring a lever mechanism for easy installation and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If threaded connections are used to couple chromatography columns, then the connection can be secure, but the coupling process becomes complex and time-consuming requiring special tools
Solution Approach 1:
The clamp is divided into distinct functional segments: a stationary clamp body with first seal, a movable clamp member with second seal, and integrated compression seals. This segmentation allows each component to perform its specific function independently while simplifying the overall coupling process compared to threaded connections.
Solution Approach 2:
The compression seals act as intermediary elements between the clamp members and chromatography columns. These seals transfer the compressive force from the clamp to the columns while creating reliable fluid-tight connections, eliminating the need for threaded fasteners and special coupling tools.
2Reliability
If threaded connections are used to couple chromatography columns, then the connection can be secure, but additional time is required for installation and removal
Solution Approach 1:
The clamp incorporates a movable clamp member that can be rapidly positioned between the stationary clamp body and the chromatography columns. This dynamic mechanism allows quick application and release of compressive force, enabling fast installation and removal of columns without the time-consuming process of threading and unthreading connections.
Solution Approach 2:
The compression seals are pre-installed and positioned within the clamp structure before use. When the movable clamp member is actuated, the compression force is immediately applied through these pre-positioned seals, creating a secure connection in a single rapid motion rather than requiring multiple steps of threading and tightening.
3Reliability
If threaded connections are used, then columns can be coupled securely, but alignment problems and leaks occur due to over-tightening or under-tightening
Solution Approach 1:
The clamp transforms the connection parameter from threaded fastening (requiring precise torque control) to compressive force application. The compression seals distribute the force uniformly across the column interfaces, maintaining consistent sealing pressure without the risk of over-tightening or under-tightening that plagues threaded connections. This parameter change eliminates alignment sensitivity and leak risks.

AI summary
A clamp for chromatography columns has a first seal with a first opening a movable seal with a second opening and a movable coupler. The movable coupler has first and second coupler seals with communicating third and fourth openings. The clamp is arranged for pressing a first chromatography column between the first seal and the first coupler seal and for pressing a second chromatography column between the movable seal and the second coupler seal, such that the first opening fluidly communicates with the second opening through the first chromatography column, the third and fourth openings and the second chromatography column.
