Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle systems lack precise monitoring of exhaust fluid levels in storage tanks, leading to potential overfilling and inefficient refilling processes, as existing level sensors only indicate if the fluid is above or below a threshold, not providing a continuous range of measurements.
Innovation Solution
Incorporating an exhaust fluid level sensor that measures the fluid level throughout a range from near empty to near full, allowing for the calculation of consumption rates and notification to the operator, enabling accurate refilling without overfilling, using a continuous level sensor like a magnetostrictive or resistive chain sensor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a threshold-level sensor is used to indicate exhaust fluid level, then the device complexity is reduced, but the measurement precision deteriorates because it only indicates above or below threshold rather than providing continuous range measurements
Solution Approach 1:
The patent replaces mechanical float-based threshold sensors with magnetostrictive or resistive chain sensors that provide continuous electronic measurements of fluid level throughout the entire tank range, enabling precise quantification of fluid levels rather than simple threshold detection
Solution Approach 2:
The invention changes the measurement parameter from binary threshold detection to continuous analog measurement throughout the fluid level range, allowing the system to provide detailed information about current fluid levels, consumption rates, and optimal refill amounts
2Measurement precision
If continuous range level sensing is implemented, then the measurement precision is improved, but the device complexity increases due to more sophisticated sensor requirements
Solution Approach 1:
The patent employs magnetostrictive or resistive chain sensors that use electromagnetic or electrical fields instead of mechanical components, providing continuous measurement capability without the complexity of mechanical moving parts while maintaining high measurement precision
Solution Approach 2:
The invention introduces a mediator substance (magnetic tape or resistive chain) that translates fluid level position into measurable electrical signals, enabling precise continuous measurement while keeping the sensor structure relatively simple and maintenance-free
3Ease of operation
If threshold-only level indication is used, then the ease of operation is maintained with simple binary feedback, but the loss of information increases as consumption rate and optimal fill amount data become unavailable
Solution Approach 1:
The patent implements a feedback system where continuous level measurements are processed to calculate consumption rates and determine optimal refill amounts, which are then communicated to the operator through the display interface, enabling informed decision-making while maintaining simple operation
Solution Approach 2:
The invention makes the level sensing system multi-functional by using the same continuous measurements to provide both simple level indication and detailed consumption analysis, eliminating the need for separate systems while enhancing operational utility
