Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional half-area touch devices in notebook computers are inconvenient due to a fixed upper region that cannot be pressed, have a complex and thick structure, and high production costs, making them unsuitable for modern light and thin notebook computers.
Innovation Solution
A full-area touch device with a movable touch control assembly supported by elastic sheet assemblies and a limiting unit structure, allowing any area to be pressed and reducing thickness through a modular, simplified design with fewer components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a half-area touch pad structure is used, then the upper half region is fixed and cannot be pressed, but this limits the pressing area and user convenience
Solution Approach 1:
The patent transforms the fixed upper half structure into a dynamic, movable structure by introducing elastic support sheets and connecting arms. The upper half region can now move relative to the lower half region through the elastic support mechanism, enabling full-area pressing while maintaining structural integrity through controlled elasticity.
2Ease of operation
If a half-area touch pad with fixed upper structure is used, then the structure becomes complicated with numerous components, but this increases device thickness
Solution Approach 1:
The patent employs elastic support sheets as flexible thin film structures to replace rigid, thick components. These elastic sheets provide the necessary support and movement functionality while maintaining a thin profile, thus reducing overall device thickness while enabling full-area touch operation.
3Adaptability or versatility
If a half-area touch pad with complicated structure is used, then numerous components are required, but this increases assembly complexity and production cost
Solution Approach 1:
The patent segments the touch pad into distinct functional modules: a lower half region, an upper half region, elastic support sheets, and connecting arms. This segmentation allows each component to be manufactured and assembled independently, simplifying the overall assembly process and reducing production complexity while achieving full-area touch coverage.

AI summary
A full-area touch device includes a touch control assembly, a plurality of support elastic sheet assemblies, a support frame and a limiting unit structure. The touch control assembly is movably disposed on the support frame. The support elastic sheet assemblies is disposed between the touch control assembly and the support frame to enable the touch control assembly to move relative to the support frame between an unpressed position and a pressed position. The limiting unit structures is disposed between the touch control assembly and the support frame for limiting height position and travel distance of the touch control assembly.
