Oil Level Sensor Dipstick Assembly for Sloped Terrain
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing engine oil level measurement systems, both manual and electric, often provide inconsistent readings due to different measurement points in the oil sump, especially when the vehicle is on a slope, leading to user confusion and potential errors in oil level assessment.
Innovation Solution
A device that integrates both manual and automatic measurement means at a single point in the oil sump, using a guiding tube with a built-in dipstick for manual measurement and a level sensor on the external surface for automatic measurement, calibrated to provide consistent oil level indications regardless of vehicle inclination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual and electric reading devices are placed in different points of the sump, then each device can function independently, but the measuring values provided by the two devices become inconsistent
Solution Approach 1:
The patent merges the manual dipstick and electric sensor into a single integrated assembly where both measurement means are positioned at the same location in the sump. The dipstick and sensor are combined in one component structure, ensuring they measure oil level at identical points, thus eliminating discrepancies between manual and electric readings while maintaining independent functionality of both systems
2Adaptability or versatility
If the vehicle is on a slope, then the vehicle can operate on varied terrain, but the oil level measurements from manual and electric devices differ significantly
Solution Approach 1:
By combining both measurement systems at one location, the patent ensures that both manual and electric readings reflect the same oil level condition regardless of vehicle inclination. This unified positioning eliminates the discrepancy that occurs when separate devices are used on slopes, as both sensors now respond to the same oil pool level at their shared measurement point
3Productivity
If the engine is running, then the vehicle can operate, but the oil has not collected in the sump and measurement is inaccurate
Solution Approach 1:
The integrated design allows continuous monitoring capability where the electric sensor provides real-time oil level data during engine operation, eliminating the need to stop the engine for measurement. The dipstick component remains available for manual verification at any time, ensuring continuous useful action for oil level assessment without interrupting vehicle operation
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures consistent oil level readings between manual and electronic systems, reducing user confusion and measurement errors by aligning sensor values with dipstick markings, and minimizing the impact of vehicle inclination on oil level detection.
Implementation Method 1
a sensor made of a conductor element whose resistance varies when it is immersed in air or in contact with the engine oil

AI summary
This invention relates to a device for reading the engine oil level suitable for both a manual and an electric reading of the engine oil level. The oil level measuring device according to this invention allows to carry out both the manual and the automatic measurement in a single point in the oil sump and it provides the level indication by a warning light or other indicators immediately visible to the driver, eliminating the differences between the two data, above all in the cases where the vehicle is not on a flat terrain.
