Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Water contamination of vehicle fluids leads to decreased performance of vehicle components, causing unsatisfactory driving experiences due to increased viscosity and corrosion, with existing solutions either failing to address cumulative issues or requiring frequent maintenance and replacement of fluids.
Innovation Solution
A system comprising an optimization server and client that uses refractometers to detect water contamination, transmitting data to a cloud server for analysis and generating parameter updates for ADAS systems to compensate for water contamination, thereby improving vehicle performance without physical changes to fluids or components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If vehicle fluids are used over time, then the vehicle operates continuously, but water contamination accumulates and degrades fluid performance
Solution Approach 1:
The system performs preliminary detection of water contamination levels in vehicle fluids using sensors and refractometers. By detecting contamination before it reaches critical levels, the system can trigger maintenance actions or parameter adjustments proactively, preventing performance degradation rather than reacting after failure occurs.
Solution Approach 2:
The system continuously monitors fluid contamination levels and provides feedback to adjust vehicle operating parameters in real-time. This feedback loop allows the vehicle to compensate for gradual fluid degradation, maintaining reliable performance over extended operation periods without immediate fluid replacement.
2Reliability
If water contamination is detected and corrected through fluid replacement, then vehicle performance is restored, but maintenance frequency and customer inconvenience increase
Solution Approach 1:
Instead of physically replacing contaminated fluids, the system changes operational parameters of vehicle components to compensate for fluid degradation. By adjusting parameters such as pump speed, pressure settings, or temperature control, the system maintains component performance despite fluid contamination, avoiding time-consuming fluid drainage and replacement procedures.
Solution Approach 2:
The system replaces mechanical fluid replacement operations with electronic parameter adjustments. Rather than using mechanical systems to drain and refill fluids, the invention uses electronic control systems to modify component behavior, substituting a time-intensive mechanical maintenance process with a rapid software-based compensation mechanism.
3Reliability
If ADAS parameters are adjusted to compensate for water contamination, then vehicle component performance is maintained, but system complexity increases
Solution Approach 1:
The system uses a universal compensation approach where a single set of parameter adjustments can address multiple types of fluid contamination and affect multiple vehicle components. Rather than implementing separate compensation mechanisms for each component or contamination type, the invention employs multi-functional parameter adjustments that simultaneously maintain performance across various systems, reducing overall complexity.

AI summary
The disclosure includes embodiments for modifying a performance of a vehicle component whose performance is affected by a vehicle fluid that is contaminated by water. A method according to some embodiments includes recording sensor data describing refractometry measurements for the vehicle fluid. The method includes determining contamination data that describes an amount of water present in the vehicle fluid. The method includes analyzing the contamination data to determine parameter data describing modifications for a set of parameters for an advanced driver assistance system (“ADAS system”) that control the operation of the ADAS system, wherein the parameter data is operable to update the set of parameters and thereby modify the operation of the ADAS system to compensate for the amount of water present in the vehicle fluid so that vehicle component performs as though the vehicle fluid is substantially not contaminated by water.
