Integrated Wiper for Camera and Illumination Window Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surveillance cameras face complications in structure due to the need for a dedicated wiper for the illumination window in addition to the camera window, which reduces brightness due to dust or snow accretions.
Innovation Solution
An imaging apparatus with a wiper that moves along the exterior surface of the camera's front light-transmission plate and can extend to a virtual surface to clean both the camera and auxiliary imaging device's front light-transmission plates without increasing the camera's structural complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated wiper for the illumination window is added in addition to the camera window wiper, then the cleaning effectiveness for both windows is improved, but the device complexity increases
Solution Approach 1:
The patent combines the camera window wiper and illumination window wiper into a single integrated wiper unit. The wiper includes a body with a camera window wiper portion and an illumination window wiper portion that are merged into one structure, allowing both windows to be cleaned by a single wiper mechanism rather than requiring separate wipers for each window.
Solution Approach 2:
The single wiper unit is designed to perform multiple functions by cleaning both the camera window and the illumination window. The wiper body is configured with portions that can contact and clean both types of windows, making the wiper a universal cleaning device that serves dual purposes without requiring additional dedicated wipers.
2Ease of operation
If separate wipers are provided for camera window and illumination window, then each window can be cleaned independently, but the number of components increases
Solution Approach 1:
The patent merges the functionality of two separate wipers into one integrated wiper unit. The wiper body contains both a camera window wiper portion and an illumination window wiper portion, reducing the total number of components from two separate wiper assemblies to a single unified structure.
Solution Approach 2:
While merging into one unit, the wiper is segmented into distinct portions: a camera window wiper portion and an illumination window wiper portion. This segmentation allows each portion to be optimized for its specific window type while still being part of a single integrated component, maintaining independent cleaning capability without requiring separate complete wiper assemblies.

AI summary
An imaging apparatus includes a camera front light-transmission plate that covers a front surface of a camera, an auxiliary device addition space which has a virtual surface obtained by an exterior surface of the camera front light-transmission plate being extended, and in which an auxiliary imaging device is provided, and a wiper that wipes the exterior surface of the camera front light-transmission plate by moving along the exterior surface and that moves to the virtual surface.
