Flexible Balancing Assembly for Smooth Key Press Feel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing key switches with balancing frame structures have poor hand feeling and user experience due to the use of hard plates, which affect the smooth pressing function.
Innovation Solution
A balancing assembly with a flexible plate, such as silica gel, is integrated between upper and lower fixing plates, providing elasticity and softness, and is connected to a balancing frame that allows smooth pressing and good tactile feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a hard plate structure is used to install the balancing frame structure, then the structural strength and stability are improved, but the hand feeling and user experience when pressing deteriorate
Solution Approach 1:
The patent applies a flexible plate made of soft material (such as rubber or silicone) that acts as a flexible shell covering the hard plate structure. This flexible plate deforms under pressing force to provide good hand feeling and tactile feedback, while the underlying hard plate maintains structural strength and stability. The flexible shell thus resolves the contradiction between structural rigidity and operational comfort.
Solution Approach 2:
The patent uses a composite structure combining a hard plate (providing strength) with a soft flexible layer (providing good hand feeling). This composite material approach allows the system to simultaneously achieve both structural integrity and comfortable tactile feedback during pressing operations, resolving the contradiction between strength and ease of operation.
2Ease of operation
If a flexible plate is added to the balance assembly, then the hand feeling and pressing feel are improved, but the device complexity increases
Solution Approach 1:
The flexible plate is integrated with the existing hard plate structure to form a unified component assembly. The flexible plate is positioned to work in conjunction with the balancing frame and hard plate, merging multiple functions (tactile feedback, force distribution, structural support) into a cohesive design that minimizes overall complexity while improving pressing feel.
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 flexible plate enhances the pressing feel and user experience by allowing direct force application on the flexible plate, ensuring smooth and balanced pressing while maintaining structural integrity.
Implementation Method 1
Since the flexible plate has the characteristics of elasticity, softness and flexibility, when pressed downward, it directly acts on the flexible plate instead of the upper fixing plate, thereby creating a good pressing feel.

AI summary
A balancing assembly with a good tactile feel. The balancing assembly comprises a lower fixing plate (1),an upper fixing plate (2) and a balancing frame (3) arranged between the upper fixing plate (2) and the lower fixing plate (1),wherein a flexible plate (4) is arranged on the upper fixing plate (2). The balancing assembly with a good tactile feel achieves a good pressing sensation while also achieving smooth pressing, thereby providing a good user experience.
