Vehicle Fuel Pump Alarm via Engine Rotation Speed Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack real-time monitoring for vehicle fuel pumps, making it difficult to determine the optimal time for maintenance and replacement, which can lead to potential car accidents due to malfunctioning fuel pumps.
Innovation Solution
An alarm system that measures engine rotation speed, calculates fuel pump consumption time, and generates a warning message when the accumulated consumption time reaches a critical value, allowing drivers to replace the fuel pump before it malfunctions, eliminating the need for professional equipment and regular maintenance facility visits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If real-time monitoring of fuel pump is implemented, then fuel pump reliability is improved, but device complexity increases
Solution Approach 1:
The patent uses engine rotation speed as an intermediary parameter to indirectly monitor fuel pump consumption. Instead of directly measuring fuel pump status, the system measures engine rotation speed (which is easily obtainable from existing sensors) and uses it to calculate fuel pump consumption time. This intermediary approach enables reliable monitoring without adding complex direct measurement devices.
Solution Approach 2:
The system leverages existing engine rotation speed data from the vehicle's own monitoring systems to calculate fuel pump consumption. The fuel pump's operational characteristics are inferred from the engine's operating parameters, allowing the system to self-monitor without external professional equipment or additional complex sensors.
2Measurement precision
If professional fuel pump testing equipment is used, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
The system enables ordinary drivers to monitor fuel pump status using the vehicle's existing onboard computers and sensors. The monitoring function is integrated into the vehicle's own systems, eliminating the need for professional technicians or external testing equipment. Drivers can check fuel pump status at any time without specialized training or equipment.
Solution Approach 2:
The patent makes the fuel pump monitoring system universal by using common engine parameters (rotation speed) that are already measured by standard vehicle systems. The same onboard computer that monitors engine performance is used to calculate fuel pump consumption, making the system accessible to all vehicles without requiring specialized equipment.
3Measurement precision
If regular maintenance facility visits are required, then measurement precision is improved, but loss of time increases
Solution Approach 1:
The system performs preliminary monitoring and calculation of fuel pump consumption continuously using onboard sensors. By the time the driver needs to know the fuel pump status, the system has already accumulated the necessary data and can provide immediate results without requiring a trip to the maintenance facility. The monitoring action is performed in advance and continuously.
Solution Approach 2:
The patent uses engine rotation speed data as an intermediary that is already being collected by the vehicle's monitoring systems. This existing data stream serves as a mediator that eliminates the need for separate maintenance facility visits, as the information is already available in real-time through the vehicle's own sensors and computer systems.

AI summary
An alarm system is used for a vehicle including a fuel pump and an engine. The alarm system includes a measuring device, a computing device and a warning device. The measuring device is used to read a current rotation speed of the engine and respectively measures a plurality of running times of a plurality of rotation speed values of the current rotation speed. The computing device calculates a plurality of consuming times of the fuel pump corresponding to the rotation speed values according to the running times of the rotation speed values, respectively. When an accumulating consuming time accumulated by the consuming times reaches a default critical value, the warning device generates a warning message.
