PTO Engagement Tracking via Relay Voltage Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for systems and methods to accurately track the amount of fuel used and the duration of operation of power transfer devices, such as PTO devices, to determine fuel tax exemptions, as existing methods are prone to errors and do not efficiently monitor these conditions.
Innovation Solution
A system comprising an electrical relay, a switch, and a processing unit that couples the relay to a reference voltage upon engagement of the power transfer device, allowing the processing unit to determine when the device is operational and track relevant conditions, including fuel usage and operation time, without relying on sensor pins and reducing human and electrical errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual tracking methods are used for PTO operation data, then device complexity is reduced, but measurement precision and reliability deteriorate due to human errors
Solution Approach 1:
The patent replaces manual mechanical tracking methods with an electronic monitoring system that uses electrical signals from the PTO engagement valve to automatically record operation data. This substitution eliminates human error in data collection while maintaining relatively simple system architecture through the use of standard electronic components like relays and data loggers.
2Reliability
If existing tracking systems are used, then device complexity is minimized, but reliability worsens due to susceptibility to human and electrical errors
Solution Approach 1:
The system automatically monitors and records PTO operation data without requiring human intervention. The electronic components self-regulate the data collection process, with the relay automatically triggering data logging when the PTO engagement valve is activated, thereby eliminating human error sources while maintaining system simplicity.
3Loss of information
If manual monitoring is employed, then ease of operation is improved, but loss of information increases due to incomplete or inaccurate data recording
Solution Approach 1:
The patent replaces manual data recording with an electronic system that automatically captures PTO operation data through electrical signal detection. This substitution ensures complete and accurate data collection while requiring minimal operational input from the operator, as the system autonomously logs all PTO engagement events.
