Adjustable Keypswitch Tactile Feedback Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional keyboards provide only a single type of tactile feedback, which cannot meet the diverse needs of users in different operation situations, leading to the need for multiple keyboards and increased costs and storage concerns.
Innovation Solution
A keyswitch structure with a base, cap, and tactile adjustment units that allow for adjustable tactile feedback by changing the position of tactile feedback members relative to cam portions, ensuring consistency and preventing deformation during adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a keyboard provides only a single type of tactile feedback, then the device complexity is reduced, but the adaptability to different user needs deteriorates
Solution Approach 1:
The patent implements a movable holder that can be adjusted to different positions relative to the cam portion, allowing the tactile feedback characteristics to be dynamically changed. The holder's position determines the engagement point with the cam portion, enabling users to switch between different tactile feedback types (e.g., linear, scissor-switch, dome) without changing the physical keyboard structure. This dynamic adjustment mechanism resolves the contradiction by providing multiple feedback options while maintaining a single keyboard unit.
2Adaptability or versatility
If the tactile feedback member is adjusted by moving it directly, then the adaptability is improved, but the member may deform during adjustment
Solution Approach 1:
The patent separates the tactile feedback member from the adjustment mechanism by introducing a movable holder as an intermediate component. The tactile feedback member remains fixed on the holder, while the holder itself is moved to adjust the engagement position with the cam portion. This segmentation prevents direct manipulation of the tactile feedback member during adjustment, eliminating deformation risks while maintaining full adjustability. The holder acts as a carrier that transfers the adjustment action without subjecting the feedback member to harmful forces.
3Adaptability or versatility
If multiple keyboards with different tactile feedbacks are purchased, then the adaptability is improved, but the cost and storage requirements increase
Solution Approach 1:
The patent makes a single keyboard universal by enabling it to provide multiple tactile feedback types through the adjustable holder mechanism. The same keyboard can be configured to deliver different tactile experiences (linear, scissor-switch, dome, etc.) by simply repositioning the holder to different locations along the cam portion. This multi-functionality eliminates the need for users to purchase and store multiple specialized keyboards, reducing both cost and storage requirements while maintaining full adaptability to different user needs and operating situations.
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 multiple tactile feedback options for users, enhancing user experience by providing different stiffness and feedback types without deforming the tactile feedback members, thus improving consistency and service life.
Implementation Method 1
a restoring member disposed between the base and the cap and configured to provide a restoring force to enable the first cam portion to move away from the base

AI summary
A keyswitch structure includes a base, a cap disposed corresponding to the base, a restoring member disposed between the base and the cap, and a tactile adjustment unit. The cap has a cam portion movable relative to the base. The restoring member is configured to provide a restoring force to enable the cam portion to move away from the base. The tactile adjustment unit is disposed corresponding to the cam portion and includes a holder and a tactile feedback member mounted on the holder. The holder is movable relative to the base to change a position of the tactile feedback member relative to the cam portion, so as to change a pressing force required for the cam portion to move toward the base.
