Cleaning apparatus for mobile electronic devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile electronic devices with touch-sensitive screens often accumulate finger marks and other stains, requiring users to manually clean them, which can be inconvenient, especially when carrying a cleaning cloth or pouch.
Innovation Solution
A housing for mobile devices with a localized cleaning material that automatically cleans the screen as the device is inserted or removed, providing dual protection and cleaning functionality without requiring specific user action, and optionally incorporating shock-absorbing materials and reversible designs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user manually carries a cleaning cloth to clean the screen, then the screen can be cleaned, but the user convenience deteriorates due to the need to carry additional items
Solution Approach 1:
The cleaning function is merged with the protective housing itself. The housing includes a localized portion of cleaning material integrated into its structure, specifically positioned to contact and clean the screen during the normal insertion or removal of the device. This eliminates the need for separate cleaning cloths or pouches.
Solution Approach 2:
The cleaning material is pre-positioned within the housing structure, ready to clean the screen automatically when the device is inserted or removed. The housing is designed with the cleaning material in place beforehand, so that the cleaning action occurs as a natural consequence of the device being placed into or taken out of the housing, without requiring any additional user action.
2Reliability
If a cleaning pouch is used to protect the device, then some protection is provided, but specific cleaning action by the user is still required
Solution Approach 1:
The housing performs the cleaning function automatically during the insertion or removal process. The localized cleaning material is positioned such that the screen contacts it during these normal operations, enabling the housing to clean itself and the device without requiring separate user action. The housing thus serves both protective and self-cleaning functions.
Solution Approach 2:
The protective housing and cleaning functions are combined into a single integrated structure. The housing not only protects the device but also incorporates cleaning material that automatically cleans the screen during insertion or removal, eliminating the need for separate cleaning pouches or cloths.
3Ease of operation
If cleaning material is placed in the housing, then automatic cleaning is achieved, but the cleaning material may contact and potentially damage the device during shock
Solution Approach 1:
A shock-absorbing material is provided between the cleaning material and the device. This cushioning layer is positioned to protect the device from shock while preventing the cleaning material from directly contacting the device during impact events. The shock-absorbing material absorbs impact forces before they can reach the device, while still allowing the cleaning material to contact and clean the screen during normal insertion or removal operations.
4Reliability
If the screen is recessed from the surround, then the screen is protected, but cleaning material must project inward to apply sufficient pressure for effective cleaning
Solution Approach 1:
The cleaning material is positioned with localized projection inward toward the screen. This projection is specifically configured to apply pressure to the recessed screen surface during insertion or removal, ensuring effective cleaning contact. The projection is localized to the area needed for cleaning the screen while maintaining the overall protective structure of the housing.
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 solution effectively cleans the screen without user intervention, protecting the device from shocks and allowing for easy cleaning of other devices, enhancing the cleaning effect by applying pressure during insertion or removal.
Implementation Method 1
a localised portion of cleaning material arranged to clean the screen of the device as the device is removed from, or inserted into the housing
Implementation Method 2
the localised portion of cleaning material may project inwardly of the inner surface of the housing, so as to apply pressure to the screen of the device
Implementation Method 3
A shock-absorbing material may be provided between the cleaning material and the pouch, to protect the device from shock without contacting the device

AI summary
A housing for a mobile device (4) comprises a pouch (1) or case including cleaning material arranged to clean the surface of the mobile device (4) as it is slid into or out of the housing. Shock-absorbing material (5) may be provided between the cleaning material (3) and the pouch (1) or case. The pouch may be reversible for use as a cleaning pad or mitt, and may include a pocket (6) for holding the mobile device when the pouch is reversed.
