Solution Overview

Problem

Electronic devices supported at a predetermined angle slip due to oblique magnetic forces acting between magnets, and stylus pens are not stably attached, leading to instability and incorrect attachment.

Innovation Solution

The electronic device includes a housing with a first side surface, a display, a closing magnet adjacent to the front surface for fixing a cover accessory, and a pen attachment magnet on a second side surface for stable stylus pen fixation, ensuring the device is securely positioned and the pen is correctly attached.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single magnet is used to fix the cover accessory, then the structure is simple, but the electronic device slips due to oblique magnetic forces when supported at an angle

Engineering Contradiction:
Improvemagnet structureVSAvoiddevice stability
Core Design Contradiction:
Device complexityVSStability of the object's composition

Solution Approach 1:

The single magnet is divided into multiple magnets (first magnet and second magnet) positioned at different locations. The first magnet is disposed at a first position and the second magnet is disposed at a second position, allowing magnetic forces to act in different directions to prevent slippage when the device is supported at an angle.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple magnets are combined to work together as a unified magnetic fixing system. The first magnet and second magnet collectively provide stable attachment of the cover accessory to the electronic device, with their combined magnetic forces counteracting the oblique forces that cause slippage.

Inventive Principle:
Principle #5Merging (Combining)

2Device complexity

If the magnet is used for both cover attachment and stylus fixation, then the number of components is reduced, but the stylus pen is incorrectly attached to the side surface

Engineering Contradiction:
Improvemagnet quantityVSAvoidattachment accuracy
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The single magnet function is segmented into separate magnets for different purposes. The first magnet (closing magnet) is dedicated to fixing the cover accessory, while the second magnet (pen attachment magnet) is dedicated to fixing the stylus pen, ensuring each component is attached to the correct location.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the electronic device are assigned different magnetic functions. The first position is optimized for cover attachment while the second position is optimized for stylus fixation, giving each location its specific functional quality appropriate to its purpose.

Inventive Principle:
Principle #3Local quality
