Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for cleaning touch screens, such as using water and cloths, often result in oily streaks and potential damage to electronic components, and fail to effectively remove fingerprints without smearing or damaging the screen.
Innovation Solution
A hand-held cleaning apparatus with a removable cap and adjustable cleaning pad containing a non-liquid cleaning composition, primarily carbon black with a binding agent, that is designed to safely remove oily residues from touch screens without leaving streaks or damaging the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If water and cloth are used to clean touch screens, then the cleaning process is simple and accessible, but it leaves oily streaks and may damage electronic components
Solution Approach 1:
The invention changes the physical state of the cleaning composition from liquid to non-liquid (powdered carbon black mixed with binding agent). This parameter change allows the cleaning material to be applied dry, eliminating the streaking and moisture damage issues associated with liquid water-based cleaning methods while maintaining ease of application.
Solution Approach 2:
The invention replaces the liquid-based mechanical cleaning system with a dry powder-based system. The powdered carbon black particles mechanically adsorb and lift oily residues from the screen surface without requiring liquid moisture, thereby eliminating the harmful effects of water-based cleaning while preserving cleaning effectiveness.
2Object-generated harmful factors
If liquid cleaning solutions are used, then they can dissolve oily residues, but they may penetrate into the device and damage electronic components
Solution Approach 1:
The invention changes the physical state parameter of the cleaning composition from liquid to solid (non-liquid powder form). This eliminates the risk of moisture penetration into electronic components while maintaining the ability to remove oily residues through the adsorptive properties of carbon black particles and the mechanical action of the pad.
Solution Approach 2:
The cleaning pad with non-liquid cleaning composition can be replaced when depleted, providing a disposable or replaceable cleaning mechanism that eliminates the need for liquid cleaners that pose infiltration risks. The pad itself becomes a contained, replaceable unit that prevents contamination of device interiors.
3Ease of operation
If traditional cleaning methods are used, then they are simple to apply, but they smear and streak the touch screen surface
Solution Approach 1:
The invention changes the physical state of the cleaning material from liquid to dry powder form. This parameter change prevents the formation of liquid streaks and smears on the screen surface, as the dry carbon black particles adsorb oils without leaving liquid residue, thereby maintaining high surface quality while keeping the application process simple.
Solution Approach 2:
The invention substitutes liquid-based cleaning mechanics with dry powder-based mechanics. The powdered carbon black particles mechanically adsorb and lift oily contaminants from the screen through friction and adhesion, then are removed without leaving streaks, preserving screen surface quality while maintaining ease of operation.
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 apparatus effectively removes fingerprints and oily deposits from touch screens without smearing or damaging the screen, maintaining the screen's clarity and safety by using a carbon black-based cleaning composition that adsorbs oils, and is designed for easy replacement and use with a mechanism to prevent contamination and reapply cleaning particles.
Implementation Method 1
