Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window cleaning technologies face challenges in efficiently cleaning the outer side of windows, especially in high-rise buildings, due to safety risks and difficulty in determining optimal movement paths based on window width, leading to inefficient cleaning and potential damage.
Innovation Solution
A window cleaning apparatus comprising a first and second cleaning unit attached to the inner and outer sides of the window using magnetic force, with a control unit that determines a movement path based on the window's width, allowing the apparatus to move along this path for effective cleaning, and includes features for easy detachment and remote control operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a window cleaning apparatus is used to clean the outer side of windows in high-rise buildings, then cleaning capability is improved, but safety risks increase
Solution Approach 1:
The patent replaces manual mechanical operation with an automated window cleaning apparatus that uses magnetic force for attachment and motor-driven mechanisms for movement and cleaning. This substitution eliminates the need for human operators to physically access dangerous heights, thereby improving safety while maintaining cleaning capability.
2Productivity
If the movement path is not determined based on window width, then device complexity is reduced, but cleaning efficiency deteriorates
Solution Approach 1:
The window cleaning apparatus automatically determines its own movement path based on the detected window width without requiring external intervention or complex pre-programming. The control unit processes the width information and generates the appropriate movement path autonomously, achieving self-service functionality that improves cleaning efficiency while avoiding excessive system complexity.
3Ease of operation
If the window cleaning apparatus is designed for easy detachment, then ease of operation is improved, but attachment reliability may worsen
Solution Approach 1:
The attachment mechanism uses controllable magnetic force that can be dynamically adjusted between strong attachment during cleaning and reduced force for easy detachment. The control unit regulates the magnetic field strength, allowing the system to maintain reliable attachment during operation while enabling simple detachment when needed, thus resolving the contradiction between attachment reliability and ease of operation.
