Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices face challenges in increasing display area while maintaining a larger keyboard area due to their compact size, and existing mechanisms for connecting sliding portions often add thickness and complexity.
Innovation Solution
A magnetic slider mechanism is introduced, allowing the base and main portions of the device to be separable and held together by magnetic force, with guide rails or grooves defining sliding directions, enabling multiple sliding motions without adding thickness and allowing the device to operate when separated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a mechanical connection mechanism (groove with peg) is used to connect the top portion and bottom portion, then the connection strength is improved, but the device thickness increases
Solution Approach 1:
The patent replaces the traditional mechanical connection mechanism (groove with peg) with a magnetic field connection system. Magnets embedded in the bottom portion attract the top portion through magnetic force, eliminating the need for mechanical interlocking structures. This substitution reduces device thickness while maintaining connection strength, as the magnetic field can exert sufficient holding force without requiring thick mechanical joints.
Solution Approach 2:
The patent changes the fundamental parameter of connection from mechanical (physical interlocking) to magnetic (field-based attraction). By using magnetic field strength as the connection parameter instead of mechanical geometry, the system achieves strong connection without increasing thickness, as magnetic forces can be optimized through material selection and positioning rather than structural dimensions.
2Reliability
If a mechanical connection mechanism is used to connect the top portion and bottom portion, then the connection reliability is improved, but the device complexity increases
Solution Approach 1:
The patent eliminates complex mechanical connection mechanisms (grooves, pegs, knobs) by substituting them with a magnetic field-based connection system. This simplifies the overall device structure while maintaining reliable connection, as the magnetic attraction provides automatic alignment and holding without requiring precision-machined mechanical interfaces or multiple moving parts.
Solution Approach 2:
The patent extracts and removes the complex mechanical connection components (groove structures, peg mechanisms) from the device design, retaining only the essential magnetic elements needed for connection. This extraction simplifies the device by eliminating unnecessary mechanical complexity while preserving the core connection function through magnetic attraction.
3Adaptability or versatility
If the device components are made separable to allow sliding motions, then the display area and keyboard area can be optimized independently, but the connection mechanism becomes more complex
Solution Approach 1:
The patent replaces complex mechanical connection mechanisms with a magnetic field-based system that enables separable components to connect and disconnect easily. The magnetic connection allows the top and bottom portions to slide relative to each other and be separated independently, optimizing display and keyboard areas without requiring complex mechanical locking or alignment mechanisms.
Solution Approach 2:
The patent creates a dynamic connection system where the magnetic force allows the components to be connected when needed and separated when desired. This dynamic capability enables sliding motions and independent optimization of different device portions while maintaining simple connection through magnetic attraction rather than fixed mechanical structures.

AI summary
A portable processing device that includes a base portion and a main portion. The base portion includes a magnet and guides. The main portion includes a magnetic area. The base portion and the main portion are separable and configured to be held together by a magnetic force between the magnetic area and the magnet. The main portion is configured to be slideably movable with respect to the base portion in a sliding direction defined by the guides. The base portion may further include a cavity adjacent to the top end of the base portion, with a second magnet disposed proximate the cavity. At the end of a sliding motion, the bottom of the main portion is pulled into the cavity by magnetic attraction between the second magnet and the magnetic area. In some embodiments the main portion may be capable of a flip with respect to the base portion.
