Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional keyboard devices with scissors-type connecting elements experience unstable keycap movement and depression, leading to reduced depressing stability.
Innovation Solution
A keyboard device featuring a wing-type connecting element with a specialized base plate and connecting bracket design, where the wing-type connecting element is swung relative to the base plate, reducing the swinging extent and enhancing stability, and allowing controlled vertical movement of the keycap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a scissors-type connecting element is used to connect the base plate and keycap, then the key structure can achieve movement, but the keycap movement becomes unstable due to excessive swinging extent
Solution Approach 1:
The connecting element is divided into a first frame and a second frame that are swingably connected together, creating a segmented structure. This segmentation allows each frame to independently control and limit the swinging motion, reducing the overall swinging extent compared to a single scissors-type connecting element while maintaining the necessary keycap movement capability.
Solution Approach 2:
The invention changes the structural parameters of the connecting element by introducing a multi-frame configuration with specific connection points. The first frame connects to the base plate at a first position and to the keycap at a second position, while the second frame connects these two frames at a third position. This parameter change in the connecting structure fundamentally reduces the swinging extent and improves stability.
2Ease of operation
If the connecting bracket is allowed to move vertically freely, then the keycap can be depressed, but the overall thickness of the keyboard device increases
Solution Approach 1:
The connecting bracket is designed with dynamic characteristics, allowing it to swing relative to the base plate during keycap depression. This swinging motion enables the bracket to accommodate the vertical movement of the keycap while maintaining a compact overall structure. The bracket can return to its original position after depression, providing reusable operation without requiring excessive thickness.
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 design enhances depressing stability and reduces the overall thickness of the keyboard device by restricting the vertical movement of the connecting bracket, providing a more stable and controlled keycap travel distance.
Implementation Method 1
When the rubbery elastomer 13 is depressed, the rubbery elastomer 13 is subjected to deformation to push the corresponding key intersection of the membrane switch circuit member 14
Implementation Method 2
In response to the elasticity of the rubbery elastomer 13, the rubbery elastomer 13 is restored to its original shape to provide an upward elastic restoring force
Implementation Method 3
The wing-type connecting element is permitted to be swung relative to the base plate. While the keycap is depressed, the first end of the first frame is moved within a first receiving space of the at least one connecting bracket in a vertical direction

AI summary
A keyboard device includes a base plate with a base plate with a connecting bracket, a wing-type connecting element and a keycap. A first connecting shaft of the wing-type connecting element is inserted into the connecting bracket, so that the wing-type connecting element is connected with the base plate. While the keycap is depressed, the first connecting shaft is inserted into a first receiving space of the connecting shaft and used as a swinging fulcrum. Since the vertical movement of the wing-type connecting element is restricted by the first receiving space, the swinging range of the wing-type connecting element is reduced. Consequently, the keyboard device of the present invention is capable of improving the depressing stability of the keycap.
