Telescopic Sprayer Attachment for Vibration-Stable Sensor Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telescopic cleaning devices for optical sensors in vehicles face attachment issues due to vibration, leading to breakage and instability, which disrupt the cleaning process and affect the operation of the sensors.
Innovation Solution
A telescopic cleaning device with a support sheath and a sprayer body that uses elastic nesting and guide surfaces with grooves to securely attach and position the sprayer, preventing translation and rotation movement, ensuring stable attachment and effective cleaning despite vehicle vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a telescopic cleaning device is attached to clean optical sensors, then the cleaning function is provided, but the attachment members are subject to vibration that weakens them and causes breakage
Solution Approach 1:
The sprayer body is inserted into and nested within the support sheath, creating a compact telescopic structure. The blocking means are integrated into this nested arrangement, with tabs on one component nesting elastically with projections on the other, providing secure attachment while maintaining the telescopic cleaning function
Solution Approach 2:
The blocking means incorporate elastic elements that can dynamically respond to vibration forces. The elastic nesting of tabs and projections allows the attachment mechanism to flex and absorb vibrational energy, preventing breakage while maintaining secure attachment during the cleaning operation
2Stability of the object's composition
If the sprayer body is securely attached in the sheath, then stable cleaning operation is achieved, but the device complexity increases due to blocking means
Solution Approach 1:
The blocking means combine multiple functions into a single integrated mechanism. The same tabs and projections that provide translation blocking also provide rotation blocking when combined with guide surfaces and grooves, eliminating the need for separate attachment mechanisms and reducing overall device complexity
Solution Approach 2:
The blocking means serve multiple purposes: they attach the sprayer body to the support sheath, prevent translation movement, and when combined with guide surfaces and grooves, prevent rotation movement. This multi-functionality maintains device stability without requiring multiple separate components
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device provides a secure and durable attachment mechanism that withstands vibrations, ensuring reliable cleaning of optical sensors over time without breakage, maintaining the sensors' operational integrity.
Implementation Method 1
the blocking means form the blocking in translation by elastic nesting of the sprayer body in the sheath
Implementation Method 2
the rotation blocking means comprise guide surfaces on one or other of the sprayer body or of the sheath interacting with at least one groove on the other of the sprayer body or of the sheath

AI summary
A telescopic cleaning device for an optical sensor of a vehicle, including a support sheath, a sprayer body, a sprayer adapted to be movable in translation relative to the sprayer body, with the sprayer body being adapted to be inserted in translation into the sheath and adapted to be attached in the sheath by blocking means. The sprayer body is thus prevented from coming out of the sheath, allowing secure attachment of the sprayer body in a vehicle. The invention also relates to a detection system and a method for assembling the telescopic cleaning device.
