Keyboard Baseplate Concave Structure for Logic Substrate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional computing systems with pointing stick devices often have a large or thick keyboard profile due to the housing of logic substrates, which can obstruct space and increase the device's thickness.
Innovation Solution
A keyboard baseplate with a concave structure is designed to house the logic substrate, allowing it to receive analog signals from a sensor and convert them to digital signals while maintaining a thin or low-profile design by positioning the substrate within the concave structure on the baseplate's lower surface, preventing it from projecting and thus allowing for a more compact form factor.

Engineering Contradiction Analysis
1Ease of operation
If the logic substrate is mounted on the keyboard baseplate using conventional methods, then the logic substrate can be properly positioned and secured, but the keyboard device becomes thicker and has a larger profile
Solution Approach 1:
The logic substrate is nested within a concave structure formed on the lower surface of the baseplate. This concave structure creates a recessed area that houses the logic substrate, allowing it to be positioned below the main plane of the baseplate. As a result, the logic substrate does not project from the baseplate, enabling a thinner keyboard profile while maintaining proper positioning and securing of the substrate through the contoured fit of the concave structure.
2Length of stationary object
If the logic substrate is positioned to reduce keyboard thickness, then a thin or low-profile design is achieved, but the logic substrate may be more exposed to environmental factors
Solution Approach 1:
The concave structure not only reduces the keyboard profile by nesting the logic substrate below the baseplate surface, but also provides a degree of environmental protection by creating a recessed housing that shields the logic substrate from direct exposure to moisture and electrostatic discharge sources in the surrounding environment.
