Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sampling apparatuses for processes, especially those involving harsh environments and liquids with suspended solids, are prone to failure and require frequent operator intervention, compromising their reliability and longevity.
Innovation Solution
A sampling apparatus with a sample chamber, a dam, and a moveable gate that reciprocates between positions to draw and eject samples through inlets and outlets, minimizing external moving parts and allowing for continuous sampling without operator intervention, equipped with sensors and optional agitation and inoculation features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If complex sampling apparatus with multiple moving parts is used, then sample retrieval capability is improved, but reliability deteriorates due to increased failure risk
Solution Approach 1:
The patent removes the complex piston and shell mechanism from the sampling apparatus, retaining only the essential sample chamber and simplified gate structure. This extraction of unnecessary components directly reduces failure points while preserving core sampling functionality, resolving the contradiction between operational capability and reliability.
Solution Approach 2:
Instead of using multiple independent moving parts (piston, shell, gate) that actuate separately, the invention inverts the approach by using a single integrated gate structure that performs multiple functions through its positional changes. This consolidation transforms a complex multi-component system into a simplified single-component system, improving reliability while maintaining sampling effectiveness.
2Adaptability or versatility
If multiple moving parts are used for sample control, then sampling function is improved, but device complexity increases
Solution Approach 1:
The single gate structure serves multiple functions: it opens to allow sample entry, closes to seal the chamber, and opens again to eject the sample. This multi-functional design eliminates the need for separate components for each operation, reducing device complexity while maintaining comprehensive sampling functionality.
Solution Approach 2:
The patent merges the functions of the piston, shell, and gate into a single integrated gate mechanism. By combining these previously separate components into one unified structure, the invention reduces the number of parts and simplifies the overall mechanism while preserving all necessary sampling operations.
3Productivity
If sample chamber is permanently inserted in process, then continuous sampling is improved, but interference from external environment increases
Solution Approach 1:
The sample chamber acts as a protective barrier that isolates the sampled liquid from external environmental factors. By permanently inserting this sealed chamber into the process, the system achieves continuous sampling while the chamber walls prevent harmful environmental interference, resolving the contradiction between productivity and environmental protection.

AI summary
An apparatus for obtaining samples from a process, and which can be located in the process, which comprises a gate which reciprocates between a first position and a second position to fill and empty a sample chamber via corresponding inlets and outlets. The gate may pivot within the chamber about a longitudinal axis through the chamber, and a dam prevents fluid flow directly between the inlets and outlets. The inlets may provide outlets, and vice versa, depending on the direction of movement of the gate. Means such as pumps may be provided to agitate the fluid samples obtained by the apparatus, and sensors mounted in the sample chamber (for example on the gate or on the dam) can perform measurements on the samples. Wipers may be provided on the gate to assist in the ingress and egress of samples into and out of the sample chamber. It is also possible to inoculate the fluid samples within the sample chamber.
