Saddled Vehicle Air Cleaner Sensor Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing design of air cleaner boxes in saddled vehicles often requires a large recess for mounting vehicle body movement sensors, which reduces the volume of the air cleaner box.
Innovation Solution
A saddled vehicle design where the vehicle body movement sensor is received in a recess defined by a flat surface crossing the rear wall of the air cleaner box, allowing the sensor to protrude slightly rearward and reducing the recess dimensions, along with a folded sensor harness and a continuous harness recess, enabling efficient placement without volume reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a large recess is formed to receive the vehicle body movement sensor and its harness coupler, then the sensor can be properly mounted, but the volume of the air cleaner box is reduced
Solution Approach 1:
The patent changes the orientation of the recess from a conventional top-surface mounting to a rear-wall mounting that extends in the vehicle width direction. This dimensional reorientation allows the sensor to be received in a recess that does not compromise the main volume of the air cleaner box, as the recess is formed on the rear wall rather than occupying space within the box's interior volume.
Solution Approach 2:
The patent segments the air cleaner box structure by forming a dedicated recess on the rear wall that is separate from the main box volume. This recess is specifically designed to receive both the vehicle body movement sensor and the sensor harness coupler, effectively partitioning the mounting function from the main air cleaning function without interfering with the box's internal capacity.
2Ease of operation
If the recess is made large enough to receive the sensor harness coupler inserted from the vehicle width direction, then the coupler can be properly received, but the air cleaner box volume is reduced
Solution Approach 1:
The patent orients the recess to extend in the vehicle width direction along the rear wall, which is the same direction from which the coupler is inserted. This alignment allows the coupler to be received along the length of the recess without requiring the recess to penetrate into the box's interior volume, thereby maintaining box volume while enabling easy coupler insertion from the side.

AI summary
A saddled vehicle includes an air cleaner and a vehicle body movement sensor. The air cleaner takes travel wind in an air cleaner box to purify air of the travel wind and supplies the purified air to an internal combustion engine. The vehicle body movement sensor is received in a recess and measures movement of a vehicle body. The recess is defined by a flat surface that crosses a rear wall of the air cleaner box. This provides a saddled vehicle including a vehicle body movement sensor that is disposed without reducing the volume of an air cleaner box.
