Jet Engine Hydraulic Tank Fluid Level Detection Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydraulic fluid tanks in jet engines face measurement deviations between sight glasses and sensor devices due to inclinations, leading to non-compliance with strict tolerance requirements and complex mounting and calibration processes.
Innovation Solution
A structural unit with a viewing device and sensor device arranged in close proximity, mounted via a fastening device, allowing independent determination of fluid levels regardless of tank inclination, with preassemblable components for simplified calibration and reduced assembly time and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the sight glass and sensor device are arranged separately on the hydraulic fluid tank, then the mounting and calibration processes become complex, but the measurement results deviate significantly when the tank is inclined
Solution Approach 1:
The patent combines the sight glass and sensor device into a single integrated assembly that is mounted together on the hydraulic fluid tank. This merging ensures both devices share the same reference plane and mounting orientation, eliminating measurement deviations caused by tank inclination while simplifying the mounting and calibration processes to a single operation
2Productivity
If the sight glass and sensor device are mounted separately, then assembly time and costs increase, but individual mounting positions can be adjusted
Solution Approach 1:
The integrated assembly merges the sight glass and sensor device into a single pre-aligned unit with a common mounting interface. This allows both devices to be installed simultaneously in one operation, reducing assembly time and costs while ensuring precise alignment through the unified mounting structure that eliminates the need for separate position adjustments
Solution Approach 2:
The sight glass and sensor device are pre-assembled and pre-aligned in the correct relative positions before being mounted on the tank. This preliminary action ensures proper alignment is achieved during manufacturing of the assembly itself, rather than requiring complex field adjustments during installation, thereby reducing both assembly time and ensuring manufacturing precision
