Resilient Element Dent Portion Soft Landing Keyboard
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern computer keyboards often cause finger fatigue due to inadequate percussive feel, leading to a mismatch between input speed and system processing speed.
Innovation Solution
A resilient element with a top surface featuring a dent portion and a conducting post, where the post volume enters an accommodating space upon pressing, providing a soft landing effect and comfortable percussion feel by extending the recovery stroke.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional resilient element is used, then the keyboard structure is simple, but the percussive feel is inadequate causing finger fatigue
Solution Approach 1:
The resilient element is divided into distinct functional regions: a top surface with a dent portion forming an accommodating space, and a conducting post beneath it. This segmentation allows different parts to perform specific functions - the accommodating space provides the soft landing effect while the conducting post maintains electrical connectivity, thereby improving percussive feel without excessive complexity.
Solution Approach 2:
The conducting post is positioned within and beneath the dent portion, with the post volume nested within the accommodating space when pressed. This nested configuration allows the smaller conducting post to be integrated into the larger resilient element structure, enabling the soft landing effect while maintaining a compact overall design.
2Ease of operation
If the resilient element structure is modified to improve percussive feel, then finger fatigue is reduced, but the device complexity increases
Solution Approach 1:
The dent portion is created locally on the top surface of the resilient element, concentrating the soft landing function in a specific region rather than requiring a complete structural overhaul. This localized modification provides improved finger comfort while keeping the rest of the resilient element structure relatively simple and manufacturable.
3Ease of manufacture
If a simple resilient element is used, then manufacturing is easy, but the recovery stroke is insufficient producing hard landing
Solution Approach 1:
The accommodating space is pre-formed in the top surface of the resilient element during manufacturing, preparing the structure in advance to accommodate the conducting post volume during pressing. This preliminary configuration ensures the soft landing effect is inherent to the design, allowing for a longer recovery stroke without complicating the manufacturing process.
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 user comfort by providing a longer stroke with a soft landing effect, reducing finger fatigue and improving input speed synchronization with system processing.
Implementation Method 1
When the resilient element is pressed, at least a portion of the post volume enters the accommodating space, and the recovery stroke of the resilient element after the contact point produces a soft landing effect
