Cleaning device and method of using a cleaning device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices struggle to effectively clean both flat and structured surfaces, particularly facade surfaces, due to the need for a design that accommodates both types of surfaces and requires a lightweight construction for easy positioning.
Innovation Solution
A modular cleaning device with movable cleaning elements that can be displaced and rotated relative to a carrier, using a drive mechanism to facilitate wiping, brushing, or rubbing, and can be attached to an aircraft for inaccessible areas, employing lightweight materials and energy sources like hydrogen fuel cells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple cleaning elements are used to clean both flat and structured surfaces, then cleaning versatility is improved, but device weight increases
Solution Approach 1:
The cleaning device is divided into multiple independent cleaning elements (first cleaning element for flat surfaces, second cleaning element for structured surfaces) that can be selectively positioned and activated. Each cleaning element is a separate functional unit that can be independently controlled, allowing the device to adapt to different surface types without carrying unnecessary components.
Solution Approach 2:
The cleaning elements are designed to be movable relative to the support structure, allowing dynamic repositioning between different cleaning positions. The drive mechanism enables the cleaning elements to be moved into and out of engagement with the surface, and allows switching between different cleaning modes (flat surface cleaning vs. structured surface cleaning) based on the actual cleaning requirements.
2Adaptability or versatility
If cleaning elements are made movable relative to the carrier, then cleaning adaptability is improved, but device complexity increases
Solution Approach 1:
The cleaning device is divided into modular components: a support structure, multiple independent cleaning elements, and a drive mechanism. Each cleaning element is a self-contained unit that can be independently positioned and controlled, simplifying the overall system architecture while enabling complex cleaning operations.
Solution Approach 2:
The support structure and drive mechanism serve multiple functions: they provide structural support, enable movement of cleaning elements, and facilitate switching between different cleaning modes. The same basic mechanism is used to position both the first cleaning element for flat surfaces and the second cleaning element for structured surfaces, reducing the need for separate specialized mechanisms.
3Weight of moving object
If lightweight materials are used to reduce device weight, then ease of positioning is improved, but structural strength may be compromised
Solution Approach 1:
The support structure and carrier components are designed as lightweight frameworks and thin-walled structures that provide sufficient structural strength while minimizing weight. The design uses optimized structural geometry and material distribution to achieve the required strength-to-weight ratio, enabling the device to be effectively positioned and maneuvered while maintaining structural integrity during cleaning operations.

AI summary
The invention relates to a cleaning device comprising a support, a drive, a holder and cleaning elements, characterized in that the holder has a longitudinal axis, on which the cleaning elements are arranged so as to be displaceable with the drive relative to the support. According to the method, the cleaning elements can be moved in opposite directions on the longitudinal axis or on axes which are arranged in parallel to one another.
