Touch Panel Assembly With Adjustable Lever-Based Pressing Feel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current touch panels in laptop computers provide a fixed pressing feel due to a fixed position of the protrusion on the housing, limiting adjustability of the pressing sensation.
Innovation Solution
A touch panel assembly with a detachable abutting structure that can be mounted at multiple positions on the touch panel base, altering the lever arm length and moment of force to provide adjustable pressing sensations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed protrusion position is used on the housing, then the structure is simple, but the pressing hand-feeling cannot be adjusted
Solution Approach 1:
The abutting structure is designed to be movable along the lever member, transforming a fixed structure into a dynamic one. This allows the pressing hand-feeling to be adjusted by changing the position of the abutting structure, while maintaining structural simplicity through a straightforward mounting mechanism
Solution Approach 2:
The abutting structure is separated into a detachable component that can be mounted at different positions on the housing. This segmentation allows users to reposition or replace the abutting structure to achieve different pressing sensations without redesigning the entire touch panel assembly
2Force
If the abutting structure is positioned to provide stronger pressing feedback, then the tactile response is enhanced, but the lever arm length is reduced
Solution Approach 1:
The system allows changing the physical parameter of lever arm length by repositioning the abutting structure. When stronger pressing feedback is needed, the abutting structure is positioned closer to the pivot point, reducing the lever arm length and increasing the mechanical advantage for force transmission
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 adjustable pressing feedback by varying the moment of force, enhancing user experience through customizable tactile responses.
Implementation Method 1
The touch panel module includes a lever member and a circuit board. The lever member is adhered to the circuit board. The circuit board includes a triggering element. When the touch panel module is pressed, the lever member is in contact with the triggering element.

AI summary
A touch panel assembly is provided and comprises a touch panel module, a touch panel base and an abutting structure. The touch panel module is arranged on the touch panel base and includes a lever member and a circuit board. The lever member is adhered to the circuit board. The circuit board includes a triggering element. When the touch panel module is pressed, the lever member is in contact with the triggering element. The abutting structure is disposed in the touch panel base, abuts against the lever member, and is detachable and optionally mounted at a plurality of different positions of the touch panel base. Corresponding to the abutting structure being at the different positions of the touch panel base, the abutting structure abuts on different portions of the lever member, so that different pressing hand-feelings are provided when the lever member is in contact with the triggering element.
