Flexible Stem Cleaner for Keyboard Gaps Without Key Presses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices, such as brushes and compressed gas canisters, are inadequate for effectively cleaning uneven surfaces like keyboards, as they can cause unintended key presses, fail to reach deep spaces between keys, and may redistribute or aerosolize contaminants, posing health risks and hygiene challenges.
Innovation Solution
A cleaning apparatus with movable, semi-rigid stems and flexible tips that extend and retract to accommodate varying surface geometries, allowing for gentle cleaning without pressing keys and incorporating a biasing element, such as gravity or pressurized gas, to maintain extended positions, and a kit with a storage vessel and dispensing mechanism for applying cleaning solutions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a wide-area flat cleaning brush is used to scrub a keyboard, then cleaning coverage is improved, but keys are pressed causing unintended actions
Solution Approach 1:
The stems are made movable between extended and retracted positions, allowing the cleaning apparatus to dynamically adapt to the keyboard surface. When stems are extended, they reach between keys without pressing them; when retracted, they avoid contact with key surfaces, thus preventing unintended key presses while maintaining wide-area cleaning capability
Solution Approach 2:
The cleaning apparatus is divided into multiple independent stems with flexible tips, each capable of independent movement. This segmentation allows different parts of the apparatus to navigate around keys independently, providing comprehensive cleaning coverage without pressing any single key, as each stem can be positioned optimally relative to the underlying keys
2Manufacturing precision
If bristles are positioned on top surfaces of keys, then key surface cleaning is improved, but bristles between keys cannot reach full depth
Solution Approach 1:
The stems can be extended to reach between keys and then flexed or tilted to direct the flexible tips toward key surfaces. This dynamic positioning allows the same bristles to alternately clean between keys at full depth and then angle toward key surfaces, achieving both deep space cleaning and key surface cleaning without requiring separate brush positions
Solution Approach 2:
The flexible tips on each stem can be oriented at different angles relative to the stem axis, allowing local adjustment of bristle direction. This enables each stem to independently optimize its cleaning angle for either inter-key spaces or key surfaces, providing both deep reach and effective surface cleaning with the same physical structure
3Productivity
If compressed gas canisters are used to blow dust from keyboards, then debris removal is improved, but contaminants are redistributed and aerosolized
Solution Approach 1:
The invention replaces the compressed gas mechanical system with a direct contact mechanical cleaning system using flexible-tipped stems. The stems physically scrub and lift contaminants from surfaces through mechanical action, then collect them on the flexible tips or in a collection mechanism, eliminating the aerosolization problem entirely by containing contaminants through direct mechanical removal rather than air flow
4Productivity
If compressed gas canisters are used for cleaning, then debris removal is improved, but noise levels increase causing distractions
Solution Approach 1:
The invention replaces the noisy compressed gas system with a quiet mechanical stem-based cleaning system. The flexible-tipped stems mechanically clean surfaces through scrubbing and lifting actions that generate minimal noise, eliminating the loud discharge sounds of gas canisters while maintaining effective contaminant removal through direct mechanical contact
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 ensures thorough cleaning of uneven surfaces without triggering key presses and effectively applies cleaning solutions, reducing health risks by ensuring thorough sanitation and minimizing contamination spread.
Implementation Method 1
Each stem is movable between a withdrawn position and an extended position with respect to the base... a biasing element biases at least one stem toward its extended position
Implementation Method 2
Flexible tips are attached respectively to the second ends of the stems... allowing for gentle cleaning without pressing keys

AI summary
A first apparatus includes a base, a plurality of stems, each stem having a first end retained by the base and a second end opposite the first end. Each stem is movable between a withdrawn position and an extended position with respect to the base, such that the second end projects from the base when the stem is in the extended position. Flexible tips are attached respectively to the second ends of the stems. A second apparatus includes a storage vessel, a cup dimensioned to receive the flexible tips of the first apparatus, and a dispensing mechanism linking the storage vessel to the cup.
