Electromagnetic Camera Wiper Assembly for Compact Cover Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning systems for miniature cameras, such as those used on rail vehicles, are too large and unsuitable for the spatially limited application scenarios, failing to provide reliable cleaning of optically transparent covers under adverse weather conditions while maintaining small dimensions.
Innovation Solution
An electromagnetic drive system with a wiper blade connected to a linkage, utilizing magnetic fields to move the wiper blade linearly over the camera cover, combined with a spring mechanism for restoring force, ensuring effective cleaning without increasing the system's size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a camera is left in a camera bag for extended periods, then the camera and lens become contaminated with dust and other contaminants, but frequent removal and cleaning increases maintenance time and risk of contamination
Solution Approach 1:
The patent applies preliminary action by providing a protective cover that is pre-assembled with a lens cap and body cap connected by a connecting piece. This pre-configuration allows the user to quickly cover the camera lens and body simultaneously with a single motion, preventing contamination before it occurs rather than requiring frequent cleaning operations.
Solution Approach 2:
The patent merges multiple protective functions into a single integrated cover structure. The cover combines the lens cap, body cap, and connecting piece into one unified assembly that protects both the lens and camera body simultaneously, reducing the number of separate maintenance actions required.
2Reliability
If protective covers are used separately for lens and body, then cleaning coverage is incomplete, but multiple separate covers increase device complexity
Solution Approach 1:
The patent merges separate protective elements (lens cap and body cap) into a single integrated cover assembly connected by a connecting piece. This unified structure provides comprehensive protection for both the lens and camera body while presenting as one simple device rather than multiple separate components.
Solution Approach 2:
The connecting piece serves multiple functions: it structurally joins the lens cap and body cap, provides an attachment point for the lanyor, and enables simultaneous coverage of both lens and body. This multi-functionality reduces the need for additional separate protective devices.

AI summary
The invention relates to an assembly for cleaning an optically translucent cover (ABD) of a camera (KAM). The camera (KAM) is arranged below the optically translucent cover (ABD) in order to be protected against environmental influences. A wiper blade (WB) is guided over the cover (ABD) in order to clean the cover (ABD), and the wiper blade (WB) is connected to a mounted linkage (STG1, STG2, STG11, STG22), by means of which the wiper blade (WB) can be moved over the cover (ABD) between a first position (POS1) and a second position (POS2). The linkage (STG1, STG2, STG11, STG22) is coupled to an electromagnetic drive (EMA), and the electromagnetic drive (EMA, EMA11, EMA21) has a drive element (PM) which is connected to the linkage (STG1, STG2, STG11, STG22) such that the drive element (PM) linearly moves the linkage (STG1, STG2, STG11, STG22). The magnetic field that is built up by the coil (SP) is coupled to the drive element (PM) such that a pushing force (FS) acting on the drive element (PM) is produced on the basis of the coupling, said pushing force being transmitted to the wiper blade (WB) via the linkage (STG1, STG2, STG11, STG22) in order to bring the wiper blade (WB) from the first position (POS1) into the second position (POS2) in a linear movement.
