Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oil sampling procedures in mechanical systems risk introducing contaminants and are difficult to pinpoint the exact location of oil extraction, complicating analysis.
Innovation Solution
A mechanical system with a sampling device featuring a pipe, anti-pollutant barrier, and sampling tube that limits contamination by restricting the flow path to a narrow passage, ensuring precise oil sampling from a specific area within the system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the plug and strainer are removed to insert a sampling tube, then oil sampling can be performed, but contaminants may be accidentally introduced into the mechanical system
Solution Approach 1:
The filler port assembly is segmented into multiple functional components: an outer housing, an anti-pollutant barrier (screen), a plug, and a sampling tube interface. This segmentation allows the anti-pollutant barrier to remain in place during sampling operations, providing continuous contamination protection while enabling oil extraction through the designated sampling tube pathway.
Solution Approach 2:
The anti-pollutant barrier acts as an intermediary element between the external environment and the internal mechanical system. It selectively permits oil to pass through to the sampling tube while blocking contaminants, thus mediating the interaction between the sampling operation and the protected mechanical system.
2Productivity
If the sampling tube is inserted through the filler port, then oil can be extracted, but the exact location of oil extraction within the mechanical system cannot be pinpointed
Solution Approach 1:
The sampling tube is designed with specific local characteristics including a predetermined length, diameter constraints, and positioning features that enable it to reach a specific location within the mechanical system. The tube's dimensions and positioning mechanism ensure it accesses a defined sampling point, providing both efficient oil extraction and precise location identification.
3Ease of operation
If the filler port is left open for sampling, then oil can be sampled, but the risk of contamination increases
Solution Approach 1:
The anti-pollutant barrier is pre-installed in the filler port assembly before sampling operations begin. This preliminary protective measure ensures that contamination protection is already in place when the sampling tube is inserted, eliminating the need to remove protective elements and maintaining system cleanliness throughout the sampling process.
Solution Approach 2:
The anti-pollutant barrier serves as a continuous intermediary protective element that remains in place during sampling operations. It mediates between the open filler port (necessary for sampling access) and the protected internal system, allowing oil to pass through to the sampling tube while blocking contaminants from entering the mechanical system.

AI summary
The present invention relates to a mechanical system (10) having a casing (20) delimiting an internal volume (INT) containing oil (15). The mechanical system (10) includes a sampling device (30) for sampling at least a portion of the oil (15). The sampling device (30) comprises at least one pipe (35) integral with the casing (20), the pipe (35) extending from an internal end (36) located within the internal volume (INT) to a neck (37) having an external end (38) open to an external environment (EXT) located outside the mechanical system (10). The sampling device (30) includes a plug (40) operable by an operator for closing the neck (37). The sampling device (30) includes, within the neck (37), a contaminant barrier (50) providing a restricted passage suitable for the passage of a sampling pipe (70).
