Keyboard Key Structure With Sliding Cover Spring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing keyboard key structures with spring shafts face challenges in structural integrity and miniaturization, leading to suboptimal auditory feedback during key presses.
Innovation Solution
A key structure design incorporating a base plate, key cap, positioning base, positioning cover, and a spring with first and second spring portions, where the positioning cover slides to compress the spring, enhancing structural integrity and auditory experience through integrated sound design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a separate elastic piece is added to create sound structure, then auditory experience is improved, but structural integrity deteriorates and device complexity increases
Solution Approach 1:
The patent merges the sound-generating function with the existing spring shaft structure. The spring shaft itself is designed to generate sound through its compression and expansion movements, eliminating the need for a separate elastic piece. This integration maintains structural integrity while achieving the desired auditory feedback.
Solution Approach 2:
The spring shaft is designed to serve multiple functions: providing mechanical support, enabling key movement, and generating auditory feedback. By making the spring shaft multi-functional, the patent eliminates the need for additional components, thereby maintaining structural integrity while improving auditory experience.

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 improves structural integrity and meets miniaturization requirements by providing enhanced auditory feedback during key presses, ensuring a better user experience while maintaining compactness.
Implementation Method 1
The spring includes a first spring portion and a second spring portion opposite to the first spring portion. The first spring portion is located in the positioning recess and is in contact with the bottom surface of the key cap. The second spring portion is located in the positioning cover and is in contact with the bottom portion of the positioning cover.
Implementation Method 2
Taking the key structure using the spring shaft (for example, a compression spring) as an example

AI summary
A key structure includes a base plate, a key cap, a positioning base, a positioning cover, and a spring. The key cap is disposed above the base plate and has a bottom surface. The positioning base is connected to the bottom surface of the key cap and has a positioning recess. The positioning cover is slidably connected to the positioning base, is inserted into the positioning recess, and includes a bottom portion and a side wall. The spring includes a first spring portion and a second spring portion. The first spring portion is located in the positioning recess and is in contact with the bottom surface of the key cap. The second spring portion is located in the positioning cover. An orthographic projection of the first spring portion on the bottom surface of the key cap is overlapped with an orthographic projection of the side wall of the positioning cover on the bottom surface of the key cap.
