Hand Squeegee Fluid-Guiding Blade for Controlled Drainage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hand cleaners with wiper blades struggle to control the flow of liquids during cleaning of smooth surfaces, leading to uncontrolled drainage, especially on vertically aligned panes, while absorbent materials fail to match the cleaning quality and speed of wiper blade systems.
Innovation Solution
A hand cleaner design featuring a carrier unit, wiper blade with guide elements, and a collecting unit, where the wiper blade is fixed to the carrier unit and has a transverse lip to guide fluids onto a guide device that directs them into a collecting unit, preventing escape and ensuring efficient fluid removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a wiper blade is used to clean smooth surfaces, then cleaning speed and quality are improved, but uncontrolled liquid drainage occurs
Solution Approach 1:
The patent introduces a collecting unit as an intermediary component between the wiper blade and the environment. This collecting unit captures and contains the liquid drawn off by the wiper blade, preventing uncontrolled drainage while maintaining the high-speed cleaning capability of the wiper blade system
Solution Approach 2:
The patent extracts the liquid collection function from the wiper blade itself by adding a separate collecting unit. This allows the wiper blade to focus on its primary function of high-speed cleaning while the collected liquid is separately managed in the collecting unit, eliminating the harmful uncontrolled drainage effect
2Object-generated harmful factors
If absorbent material is used to clean smooth surfaces, then uncontrolled liquid drainage is avoided, but cleaning quality and speed are reduced
Solution Approach 1:
The patent merges the advantages of both wiper blade and absorbent material approaches by combining a wiper blade (for high-speed cleaning) with a collecting unit that contains and manages the collected liquid. This hybrid solution achieves both high cleaning productivity and controlled liquid management
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design effectively prevents uncontrolled fluid flow, maintains high cleaning quality and speed, and allows for efficient collection and disposal of fluids, suitable for smooth surfaces like window panes and vehicle windshields.
Implementation Method 1
a wiper blade made of elastic material... to press a disc and then to move along the disc. The wiper blade pulls off liquids on the windshield in the direction of movement.
Implementation Method 2
the wiper blade has at least in regions a guide element which is designed to guide a fluid located on the wiper blade in the direction of the guiding device
Implementation Method 3
the guiding device is arranged adjacent to the wiper blade and borders on the collecting unit in order to collect the fluid from the wiper blade
