Detachable Input Unit Pad and Magnetic Connection for Tablet-Laptop Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices, such as laptops and tablets, lack a flexible and convenient method for data input, as they either have undetachable keyboards or restrict the use of external keyboards and touchpads.
Innovation Solution
An electronic device design featuring a detachable input unit with a pad and support that contacts a surface for stability when detached, and a magnetic connection for secure assembly with the main body, allowing for conversion between tablet and laptop modes with reduced friction for easy assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the input unit is made detachable to enable flexible usage modes, then adaptability is improved, but connection stability and assembly reliability deteriorate
Solution Approach 1:
The patent replaces traditional mechanical connection methods (screws, clips, or complex latches) with a magnetic connection system. The magnetic elements provide automatic alignment and secure attachment when the input unit is connected to the main body, ensuring reliable connection while maintaining detachability for flexible usage modes.
2Stability of the object's composition
If the pad protrudes longer to contact the surface when detached, then stability is improved, but friction interference during assembly increases
Solution Approach 1:
The magnetic elements are positioned in advance within the housing structure, creating a magnetic field that guides and attracts the input unit toward the main body during assembly. This preliminary magnetic action occurs before physical contact, pulling the input unit into proper alignment and reducing friction interference during the connection process.
Solution Approach 2:
The magnetic force acts as an intermediary between the input unit and main body during assembly. Instead of direct mechanical contact that causes friction, the magnetic field mediates the connection process by attracting components together smoothly, allowing the pad to maintain surface contact for stability while enabling easy assembly.
3Stability of the object's composition
If the support protrudes longer to provide stability when detached, then stability is improved, but device complexity increases
Solution Approach 1:
The housing structure serves multiple functions: it provides mechanical support, contains the magnetic elements for connection, and forms the structural framework for both detached and connected states. The support protrusion is integrated into this multi-functional housing rather than being a separate component, reducing overall device complexity while maintaining stability when detached.

AI summary
An electronic device is provided, including a main body, a display unit connected to the main body, and an input unit detachably connected to the main body. The input unit has a pad protruding from the bottom side thereof. When the input unit is placed on a surface of an object, the pad contacts the surface. When the main body is placed on the surface and joined with the input unit, the pad and the surface form a distance therebetween.
