Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Collapsible terminal devices are difficult to open with one hand, requiring simultaneous operation of both hands or insertion of a thumb into a narrow gap, making them less user-friendly.
Innovation Solution
Incorporation of a first and second folding portion with magnetic components and an adjustment component that allows for magnetic attraction and repulsion, enabling single-handed operation and adjustable force for easy opening and closing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the screen size is increased, then the display area is improved, but the device size becomes larger and portability deteriorates
Solution Approach 1:
The device is divided into multiple folding portions (first folding portion, second folding portion) that can be rotated relative to each other. This segmentation allows the large screen to be folded into a compact form factor, achieving both large display area and small portable size.
Solution Approach 2:
The folding portions are designed to be rotatable between folded and unfolded states, transforming the device from a static to a dynamic structure. This enables the device to adapt its size - large when unfolded for display, compact when folded for portability.
2Volume of moving object
If the device is designed to be collapsible, then portability is improved, but ease of operation deteriorates due to difficulty in opening with one hand
Solution Approach 1:
The manual mechanical operation of opening the device is replaced with a magnetic field-based system. Magnetic components generate attractive or repulsive forces that automatically assist the opening and closing actions, eliminating the need for complex manual manipulation or thumb insertion into narrow gaps.
Solution Approach 2:
An adjustment component is provided to change the magnetic force parameters (attractive or repulsive). By adjusting the magnetic force strength, the device can be optimized for different operating conditions, enabling easy one-handed operation while maintaining compact folded state.
3Ease of operation
If magnetic components are added to enable easy opening, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The magnetic components serve multiple functions: they assist in opening the device, assist in closing the device, and can be adjusted to provide different force levels. This multi-functionality reduces the need for separate mechanical mechanisms for each operation, thereby limiting the increase in complexity.
Solution Approach 2:
Magnetic field is used as an intermediary force between the user's action and the folding portions. Instead of direct mechanical contact requiring precise alignment and force application, the magnetic field provides a distributed, contactless force that simplifies the interaction while adding minimal structural complexity.
