Side Turn Signal Camera Cleaner With Rubber Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vibrations from the reciprocation of a piston in a vehicle air cleaner unit cause deviations in the relative position between the nozzle and the to-be-cleaned object, leading to inaccurate cleaning, and there is a need for a cleaner to maintain a side turn signal lamp with a camera on vehicles capable of automatic driving.
Innovation Solution
A vehicle cleaner unit with a cylinder and power unit supported by rubber members to suppress vibrations, and a side turn signal lamp with a camera that includes a cleaning medium delivery system to accurately clean the camera lens, using a casing with integrated attachment parts for the light source, camera, and cleaner units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the piston reciprocates inside the cylinder to discharge cleaning medium, then cleaning function is achieved, but vibrations are generated causing position deviation
Solution Approach 1:
A rubber member is introduced as an intermediary vibration-absorbing element between the piston and the nozzle. The rubber member absorbs vibrations generated by piston reciprocation, preventing them from being transmitted to the nozzle and causing position deviation. This mediator resolves the contradiction by allowing the piston to reciprocate for cleaning while isolating the vibration that would compromise positioning accuracy.
Solution Approach 2:
The rubber member is pre-installed in the nozzle as a vibration-absorbing cushion before the piston begins reciprocation. This beforehand cushioning prepares the system to absorb upcoming vibrations, preventing position deviation before it occurs. The rubber member acts as a pre-positioned buffer that mitigates the harmful effects of piston-driven vibrations on cleaning accuracy.
2Extent of automation
If the side turn signal lamp with camera is mounted on vehicles capable of automatic driving, then automation functionality is enhanced, but a cleaner configured to clean the camera is required
Solution Approach 1:
The cleaner unit is merged with the side turn signal lamp assembly, combining two separate functions (cleaning and lighting/signaling) into a single integrated device. The cleaner unit includes a cylinder, piston, and nozzle that work together with the turn signal lamp and camera components. This merging reduces overall system complexity by eliminating the need for separate mounting of independent cleaner and turn signal units, while maintaining automation functionality.

AI summary
This vehicle cleaner unit is provided with: a cylinder unit comprising a cylinder which forms a chamber, a discharge port through which the chamber opens to the outside, and a piston which reciprocates inside of the cylinder and discharges from the discharge port a cleaning medium inside of the chamber; a power unit comprising a motor, a power transmission mechanism which transmits rotary motion of the motor to the piston to cause the piston to reciprocate, and a housing which houses the motor and the power transmission mechanism; and a casing which houses the cylinder unit and the power unit. The cylinder unit and the power unit are supported by the casing with rubber members interposed therebetween.
