Oil Dipstick Seal Element for Leakage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for leakage testing and readability of oil dip-sticks in internal combustion engines are complex and costly, with multiple sealing points requiring high imperviousness testing, leading to potential leaks and increased costs.
Innovation Solution
A measuring rod with a seal element on the measuring tongue, which seals off from the guide tube, allowing for simple leakage testing and improved readability by isolating the lubricant from the guide tube, reducing the need for multiple sealing points and costly imperviousness testing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple sealing points are used to prevent lubricant leakage, then reliability is improved, but device complexity and manufacturing costs increase
Solution Approach 1:
The patent extracts the sealing function from multiple separate sealing points and concentrates it into a single sealing element located at the distal end of the measuring tongue. This single seal element prevents lubricant from entering the guide tube, eliminating the need for multiple sealing locations and simplifying the overall structure while maintaining reliability.
Solution Approach 2:
The seal element acts as an intermediary component between the measuring tongue and the guide tube. It creates a reliable seal that prevents lubricant leakage without requiring complex multi-point sealing arrangements, thus reducing device complexity while maintaining protection against harmful factors.
2Reliability
If multiple sealing points are implemented, then leakage testing becomes more thorough, but testing complexity and costs increase
Solution Approach 1:
The patent extracts the critical sealing function to a single location at the distal end of the measuring tongue, which is the only point that requires sealing. This eliminates the need to test multiple sealing points, thereby simplifying leakage testing procedures while maintaining thoroughness in testing the single critical seal element.
3Reliability
If the guide tube is exposed to lubricant, then sealing is achieved, but oil deposition and stripping occur reducing readability
Solution Approach 1:
The patent extracts the sealing function to a single seal element at the distal end of the measuring tongue, which prevents lubricant from entering the guide tube. This ensures the guide tube remains dry and free from oil deposition, maintaining readability while achieving reliable sealing at the critical interface between the measuring tongue and guide tube.
Solution Approach 2:
The seal element serves as an intermediary that creates a barrier between the lubricant and the guide tube. This single sealing point effectively prevents oil from depositing on or stripping from the guide tube, eliminating harmful effects while maintaining sealing integrity.
4Reliability
If conventional sealing methods are used, then leakage is prevented, but manufacturing costs increase
Solution Approach 1:
The patent extracts the sealing function to a single seal element location, significantly reducing the number of components and assembly steps required. This simplification of the sealing system reduces manufacturing complexity and cost while maintaining effective leakage prevention through the single critical seal element.

Implementation Method 1
at least one or precisely one seal element arranged on the measuring tongue, by means of which seal element the measuring rod is to be sealed off from a guide tube for guiding the measuring rod
Implementation Method 2
a wetting of the measuring tongue with the lubricant resulting from an immersing of the measuring tongue into the lubricant accommodated in the reservoir can be visually determined

AI summary
A measuring rod for measuring a fill level of a lubricant in a reservoir of an internal combustion engine includes a rod element, at one end of which is arranged a measuring tongue which can be submerged into the lubricant and by which the fill level can be measured and can be detected visually. At least one sealing element is arranged on the measuring tongue, by way of which the measuring rod can be sealed in relation to a guide tube for guiding the measuring rod.
