Straddle Vehicle Detection Unit Cleaning via Movable Windscreen
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Contamination on the lens unit of a detection unit in a straddle type vehicle, such as dirt, affects the accuracy of detection values, necessitating effective cleaning methods.
Innovation Solution
A straddle type vehicle equipped with a detection unit and a cleaning unit that can change position relative to the detection unit, using a movable mechanism to wipe the detection unit, including a windscreen that moves between different positions to facilitate cleaning, with a driving mechanism and actuator controlling the position changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the detection unit is fixed in position, then the structure is simple, but the cleaning unit cannot effectively reach and clean the detection unit
Solution Approach 1:
The cleaning unit is made movable relative to the detection unit through a position changing mechanism, allowing the cleaning unit to dynamically adjust its position to effectively reach and clean the detection unit from different angles and distances
2Adaptability or versatility
If the windscreen is fixed, then the structure is simple, but the cleaning unit cannot access the detection unit during travel
Solution Approach 1:
The windscreen is designed to be movable between different positions (e.g., raised and lowered), allowing the cleaning unit to access the detection unit when the windscreen is in a specific position, while maintaining aerodynamic performance when the windscreen is in its normal operating position
Solution Approach 2:
The windscreen is positioned in advance to a specific location before cleaning is required, creating an accessible pathway for the cleaning unit to reach the detection unit without interfering with normal vehicle operation
3Measurement precision
If the cleaning unit is positioned far from the detection unit, then the detection unit is protected from contamination, but the cleaning unit cannot effectively wipe the detection unit
Solution Approach 1:
The cleaning unit dynamically adjusts its position to be close to the detection unit during cleaning operations, enabling effective wiping while maintaining the detection unit's protection from contamination when not in use

AI summary
A straddle type vehicle comprises: a detection unit for detecting a condition of front of a vehicle; a cleaning member capable of cleaning the detection unit; and a movable apparatus for changing a position of the cleaning member in relation to the detection unit in a height direction of the vehicle, wherein the cleaning member, by the changing of the position, performs the cleaning by wiping with a portion of the detection unit where the cleaning unit contacts the detection unit.
