Magnetic Keyswitch Bracket for Stable Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional adjustable keyboards rely on unstable gravity force for keycap height adjustment, leading to inaccurate positioning over long-term use, which affects operational reliability.
Innovation Solution
A magnetic keyswitch design utilizing a movable bracket and magnetic attractive force to adjust the height of keycaps, where a magnetic portion on the bracket interacts with a curved supporter to either support or descend the keycap based on its position, allowing for stable and reliable height adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If gravity force is used to descend the keycap to the lowest position, then the keycap can be adjusted to a low position, but the drop path becomes unstable and the keycap cannot be descended to the predetermined lowest position accurately after long-term repetitive usage
Solution Approach 1:
The patent replaces the gravity-based mechanical descent system with a magnetic field-based system. A magnetic portion on the bracket interacts with a magnetic portion on the curved supporter to provide controlled magnetic attractive force, eliminating the instability and inaccuracy associated with gravity-driven mechanical systems while maintaining the ability to adjust keycap height reliably over time
2Length of stationary object
If a thin-typed keyboard design is used to meet aesthetic requirements, then the device achieves a thin profile, but the travel stroke becomes short and sufficient force feedback cannot be provided to the user
Solution Approach 1:
The patent makes the keyboard structure dynamically adjustable by allowing the bracket to slide relative to the base between different positions. This enables the keyboard to change its entity structural height and travel stroke dynamically, providing long travel stroke and sufficient force feedback when needed while maintaining a thin profile when not in use, thus resolving the contradiction between thin design and operational comfort

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 magnetic keyswitch provides a simple and reliable mechanism for height adjustment, ensuring stable operational performance and suitable for thin-type electronic devices by using magnetic forces for upward and downward keycap movement, enhancing user feedback and reducing structural height variability.
Implementation Method 1
An attractive force is generated between the second magnetic portion and the first end when the bracket is located at the first position, so that the second end supports the keycap at a first height
Implementation Method 2
The attractive force between the first magnetic portion and the second magnetic portion is removed when the bracket moves to the second position, and the keycap is descended to a second height by an external force

AI summary
A magnetic keyswitch includes a base, a keycap, a curved supporter, a bracket and a second magnetic portion. The keycap moves relative to the base upwardly and downwardly. The curved supporter is disposed between the keycap and the base and has a first end and a second end. A first magnetic portion is disposed on the first end. The bracket slides relative to the base and is switched between a first position and a second position. The second magnetic portion is disposed on the bracket. An attractive force is generated between the second magnetic portion and the first end when the bracket is located at the first position, so that the second end supports the keycap at a first height. The attractive force is removed when the bracket moves to the second position, and the keycap is descended to a second height by an external force.
