Straddle-Type Vehicle Sensor Mounting for Vibration Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Straddle-type vehicle body behavior sensors face challenges in accurately detecting vehicle behavior due to high-frequency vibrations, particularly radio frequency waves, which affect the accuracy of their detection signals.
Innovation Solution
The vehicle body behavior sensor is mounted on a support member that also supports a heavy weight vehicle member, such as a head lamp unit or battery, to reduce high-frequency vibrations, and is positioned between the head lamp unit and the head pipe or under the seat, enhancing signal accuracy without increasing the number of components or size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the vehicle body behavior sensor is mounted on the vehicle body, then it can detect vehicle body behavior, but high-frequency vibrations are transmitted to the sensor and reduce detection accuracy
Solution Approach 1:
The patent introduces a support member as an intermediary structure between the vehicle body and the sensor. This support member is specifically designed to be rigid and resistant to high-frequency vibrations, thereby mediating the transmission of vibrations to the sensor and improving detection accuracy
2Measurement precision
If a new support structure is added to reduce vibrations, then sensor accuracy improves, but the number of components and device complexity increases
Solution Approach 1:
The patent designs the support member to serve multiple functions: it provides structural support for the sensor, acts as a vibration-resistant mounting platform, and integrates with the existing vehicle body structure. This multi-functionality approach avoids adding unnecessary components while achieving vibration reduction
3Device complexity
If the sensor is mounted on existing vehicle members, then device complexity is minimized, but the sensor is still affected by high-frequency vibrations
Solution Approach 1:
The patent applies local quality by designing the support member with specific local characteristics - it is constructed to be particularly rigid and resistant to high-frequency vibrations at the mounting location, while the rest of the vehicle body structure remains unchanged. This localized enhancement provides vibration resistance without requiring complete structural redesign
