Keyboard Finger Guide with Malleable Curvilinear Dividers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing keyboard guide devices are not suitable for experienced users or those typing in low light conditions, as they are either too rigid or not beneficial for guiding finger placement accurately without restricting finger movement.
Innovation Solution
A keyboard finger placement guide with elongated dividers and curvilinear guides made from malleable, resilient materials that extend above or level with the keyboard keys, providing tactile guidance for the first two fingers without restricting outer fingers, and featuring bright or neon colors for visual alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If rigid frames extending above the keyboard are used to guide finger placement, then finger placement guidance is provided, but finger movement is restricted
Solution Approach 1:
The patent uses a flexible membrane with cutouts instead of rigid frames. The membrane can be depressed by fingers, allowing natural finger movement while still providing tactile guidance through the cutout patterns that indicate proper finger placement positions.
Solution Approach 2:
The patent changes the physical state of the guide from rigid to flexible. The membrane's ability to deform under finger pressure allows it to adapt to different typing forces and finger movements, maintaining guidance functionality while eliminating movement restrictions.
2Measurement precision
If raised frames are used to bracket fingers, then proper hand placement is enforced, but outer finger movement is restricted
Solution Approach 1:
The patent divides the keyboard surface into segmented zones using cutouts in the membrane, with each cutout corresponding to a specific finger placement zone. This segmentation provides guidance without creating continuous rigid boundaries that would restrict outer finger movements.
Solution Approach 2:
The flexible membrane acts as an intermediary between the keyboard surface and the user's fingers. It provides tactile feedback and guidance through its deformation characteristics and cutout patterns, while remaining sufficiently compliant to allow natural finger movements.
3Measurement precision
If visual indicators are added to show proper hand placement, then finger alignment is improved, but device complexity increases
Solution Approach 1:
The patent incorporates color-coded or visually distinct regions in the membrane to indicate proper finger placement zones. These visual indicators are integrated into the membrane design itself, providing alignment guidance without requiring separate complex indicator systems.

AI summary
A keyboard finger guide device includes an elongated divider this is positionable horizontally between two rows of a keyboard, and a plurality of curvilinear guides that are secured to the divider perpendicularly and are positionable vertically between a plurality of individual keys of the keyboard. The guides are constructed from a malleable and resilient material and can extend above the top surface of the keyboard keys to provide a constant guide for the first two fingers of a user's left and right hands in the typing position at rest. The guides can also extend level with the top surface of the keyboard keys at rest to selectively guide the first two fingers of a user's left and right hands while typing.
