Segmented Magnetic Keyboard for Mobile Touch-Typing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable keyboards for mobile devices are either too large when designed for laptops or unsuitable for touch-typing due to their compact form-factor, failing to provide efficient typing experiences.
Innovation Solution
A compact, portable wireless keyboard with dissociable elements, including two key arrays and a spacebar, using magnetic forces for assembly and disassembly, and equipped with capacitive sensors and a wireless signaling module for efficient data transmission and power management, allowing for ergonomic comfort and touch-typing capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a keyboard is designed for laptop use, then the keyboard provides full typing functionality, but the keyboard becomes too large and heavy for mobile devices
Solution Approach 1:
The keyboard is divided into two separate key arrays (first and second key arrays) that can be used independently or combined together, allowing users to carry only the necessary portion for their specific typing needs while maintaining full QWERTY functionality when both are assembled
Solution Approach 2:
The patent transitions from a traditional single-plane keyboard layout to a multi-dimensional configuration where key arrays can be stacked vertically and folded together, creating a compact form factor that preserves full typing functionality in a reduced footprint suitable for mobile devices
2Weight of moving object
If a keyboard is shrunk to a compact form-factor, then the keyboard becomes portable for mobile devices, but the keyboard becomes unsuitable for touch-typing
Solution Approach 1:
Each key array maintains a complete set of QWERTY keys with proper spacing and layout, allowing users to achieve touch-typing proficiency on either array independently or in combination, preserving ergonomic typing capability despite the compact overall form factor
Solution Approach 2:
The second key array is designed to nest within or alongside the first key array when not in use, creating a compact configuration that preserves full keyboard functionality while reducing the overall footprint to be portable for mobile devices
3Ease of operation
If a keyboard uses magnetic assembly for portability, then the keyboard can be easily assembled and disassembled, but the magnetic connection strength must be sufficient to maintain stability during use
Solution Approach 1:
The patent replaces traditional mechanical fastening systems (screws, clips, adhesives) with magnetic coupling between key arrays, enabling tool-free assembly and disassembly while maintaining stable connection during typing through properly positioned magnetic elements that provide sufficient holding force
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 keyboard offers a compact form factor suitable for touch-typing, efficient data transmission, and power management, enhancing the typing experience on mobile devices while maintaining portability and ergonomic comfort.
Implementation Method 1
magnetic masses disposed within the spacebar and within each key array... the magnetic forces between the magnetic masses and the magnets draw the dissociable elements together to form a unitary keyboard
Implementation Method 2
Each key is associated with a capacitive sensor that detects key press events

AI summary
An ultra compact mobile keyboard. The keyboard has a plurality of mechanical keys suitable for touch typing. Each such key has a travel distance sufficient to provide a touch type feel and a rigid cap for crisp actuation by a user. The keyboard has a deployed configuration for touch-typing use and a collapsed configuration for transport and storage. In the collapsed configuration, the keyboard fits within bounding volume of less than 180 cubic centimeters.
