Adjustable Keystroke Force Input Device Using Dynamic Magnetic Repulsion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing keyboards lack the ability to adjust keystroke force, which is essential for user preference in gaming and typing experiences, as they rely on fixed magnetic mechanisms that do not allow for customizable feedback.
Innovation Solution
An input device with a movable keycap and second magnet, where the poles of the magnets point in opposite directions, allowing for adjustable keystroke force through a sliding magnet rack mechanism that can be controlled by an electrical actuator, enabling users to adjust the force based on application needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed magnetic mechanism is used in the keyboard, then the structure is simple and reliable, but the keystroke force cannot be adjusted according to user preference
Solution Approach 1:
The patent applies the dynamics principle by making the second magnet movable relative to the housing instead of fixed. The second magnet can be positioned at different locations to adjust the magnetic repulsion force experienced by the keycap, thereby customizing the keystroke force. This transforms a static magnetic mechanism into a dynamic one that can adapt to different user preferences while maintaining relatively simple structure.
2Adaptability or versatility
If like poles of magnets are facing each other to create opposing force, then the keycap returns to initial position, but the keystroke force is fixed and cannot be customized
Solution Approach 1:
The second magnet is made movable along the base, allowing its position to be adjusted dynamically. When the second magnet is positioned closer to the first magnet in the keycap, the magnetic repulsion force increases, creating a stronger opposing force and higher keystroke force. When positioned farther away, the repulsion force decreases, resulting in softer keystroke. This dynamic positioning enables customization of keystroke force while maintaining the simple like-pole-facing arrangement.
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
Enables users to customize keystroke force to suit their preferences, providing either softer feedback for gaming or harder feedback for typing by aligning or misaligning the magnets, thereby enhancing user experience.
Implementation Method 1
a first magnet is provided in or on the keycap and a second magnet is provided at a base such that like poles of the first and second magnets are facing each other in spaced apart relation. The first and second magnets are arranged to create an opposing force between them that acts to return the key member towards the initial position when the applied force is removed.
