Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatuses with pen-shaped device attachment structures using magnetic forces face limitations in terms of flexibility and convenience, particularly in narrow frame structures where large magnetic attraction portions are difficult to accommodate.
Innovation Solution
The electronic apparatus features a chassis with switchable postures between closed, open, and fully open positions, incorporating first and second magnetic attraction portions with varying magnetic forces, allowing the pen-shaped device to automatically move between attachment positions based on chassis posture changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large magnetic attraction portion is provided to strongly attract the pen-shaped device, then the attachment reliability is improved, but the device cannot be accommodated in narrow frame structures
Solution Approach 1:
The magnetic attraction function is divided into two separate magnetic attraction portions: a first magnetic attraction portion in the first chassis and a second magnetic attraction portion in the second chassis. This segmentation allows each portion to be smaller in size while collectively providing sufficient magnetic attraction force, enabling accommodation in narrow frame structures while maintaining attachment reliability.
Solution Approach 2:
The patent combines the magnetic attraction functions of two separate chassis (first chassis and second chassis) to achieve the overall attachment effect. When the chassis are in the closed posture, both magnetic attraction portions work together to securely hold the pen-shaped device, merging their individual weak magnetic forces into a effective combined attraction.
2Ease of operation
If the pen-shaped device is attached to the first chassis, then it is easily accessible during use, but it cannot be securely carried when the chassis is closed
Solution Approach 1:
The attachment system dynamically adapts to different chassis postures. In the open posture, the first magnetic attraction portion actively attracts the pen-shaped device to the first chassis for easy accessibility. In the closed posture, the second magnetic attraction portion becomes active to attract the device to the second chassis for secure carrying. This dynamic switching ensures both ease of operation and security at different usage states.
Solution Approach 2:
The magnetic attraction portions automatically switch functionality based on chassis posture without user intervention. The system self-adjusts which magnetic attraction portion is active, providing the appropriate attachment behavior (accessibility or security) according to the current state of the chassis.
3Reliability
If magnetic attraction portions are placed adjacent to each other in closed posture, then the pen-shaped device can be securely held, but the structure becomes more complex
Solution Approach 1:
Each chassis serves multiple functions: the first chassis provides the first magnetic attraction portion for accessibility, and the second chassis provides the second magnetic attraction portion for secure carrying. Both chassis are universally designed to participate in magnetic attraction regardless of posture, reducing the need for additional specialized components and simplifying the overall structure.

AI summary
An electronic apparatus includes: a chassis including a first chassis having a first facing surface and a second chassis having a second facing surface; a first magnetic attraction portion provided in the first chassis and configured to magnetically attract a pen-shaped device to a first attraction position of the first chassis; and a second magnetic attraction portion provided in the second chassis and configured to magnetically attract the pen-shaped device to a second attraction position of the second chassis. A posture of the chassis is switchable between a closed posture in which the first facing surface and the second facing surface face each other and an open posture in which the first facing surface and the second facing surface do not face each other.
