Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Straddle-type vehicles, such as motorcycles, face challenges in detecting impending component failures due to wear and tear, which can lead to vehicle inoperability if not addressed promptly.
Innovation Solution
The system employs vibration sensors, such as accelerometers, to sense vibrations produced by the vehicle and an electronic processor to analyze these vibrations for predetermined frequency ranges and thresholds, thereby identifying component faults and executing mitigation actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vibration sensors and analysis systems are installed to detect component faults, then reliability of vehicle operation is improved, but device complexity increases
Solution Approach 1:
The system enables the vehicle to self-diagnose component faults by automatically monitoring vibrations and comparing them against stored baseline patterns, eliminating the need for manual inspection and reducing dependency on external diagnostic services
Solution Approach 2:
The patent replaces manual mechanical inspection methods with electronic vibration sensing and digital signal processing, using accelerometers and microprocessors to automatically detect and diagnose component conditions
2Loss of time
If continuous vibration monitoring is performed to detect faults early, then loss of time for maintenance is reduced, but use of energy increases
Solution Approach 1:
The system performs vibration analysis periodically at predetermined intervals rather than continuously, analyzing vibrations only during specific engine operating conditions to reduce energy consumption while maintaining effective fault detection timing
Solution Approach 2:
The system adjusts monitoring parameters dynamically based on engine operating conditions, activating vibration analysis only when specific RPM ranges or load conditions are met, thereby reducing energy usage during inappropriate operating states

AI summary
Systems and methods for detecting component faults for a straddle-type vehicle using sensed vibrations. One example system includes a vibration sensor positioned at a first position on the straddle-type vehicle and configured to sense vibrations of the straddle-type vehicle and an electronic processor communicatively coupled to the vibration sensor. The electronic processor is configured to receive, from the vibration sensor, sensor information, determine, based on the sensor information, whether a vibration is present at a predetermined frequency range, and determine, in response to determining that the vibration is present at the predetermined frequency range, whether a characteristic of the vibration exceeds a predetermined threshold. The electronic processor is further configured to, in response to determining that the characteristic exceeds the predetermined threshold, identify a fault with a component of the straddle-type vehicle corresponding to the predetermined threshold and execute a mitigation action based on the fault.
