Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smartwatches face challenges in convenient content adjustment due to small screen sizes and mechanical rotary switch limitations, leading to false triggering and unreliable operation.
Innovation Solution
A magnetic adjustment mechanism with a magnetic ring and sensor, or an optical adjustment mechanism with a sliding piece, generates pulse signals to process and display adjusted content, enhancing user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mechanical rotary switch with brush gears is used for content adjustment, then the device can perform man-machine interaction functions, but the quantity of brush gears is limited by the size of the smartwatch, making it difficult to adjust software identification threshold and step value, resulting in undesirable user experience
Solution Approach 1:
The patent replaces the mechanical rotary switch with brush gears with a magnetic adjustment mechanism consisting of a magnetic ring and magnetic sensor. This substitution eliminates the need for multiple brush gears while maintaining the rotation detection function. The magnetic ring with magnetic sets generates magnetic field changes that are detected by the magnetic sensor to produce pulse signals, achieving the same man-machine interaction function without the limitations of mechanical brush gear quantity.
2Ease of operation
If a mechanical rotary switch is used for content adjustment, then the device can perform paging and zooming functions, but false triggering is prone to occur due to factors such as a small size of the screen or a wobble in a moving state
Solution Approach 1:
The patent replaces the mechanical rotary switch with a magnetic adjustment mechanism. The magnetic ring and magnetic sensor configuration eliminates false triggering issues associated with mechanical switches. The magnetic field detection method is more stable and less susceptible to wobble and screen size limitations, significantly improving operation reliability while maintaining content adjustment functionality.
3Volume of moving object
If the screen size is kept small to meet wearable device requirements, then the device maintains its wearable characteristics, but false triggering is more prone to occur when the finger directly touches the display screen
Solution Approach 1:
The patent introduces a magnetic ring as an intermediary component between the user and the display screen. Instead of directly touching the small screen which causes false triggering, the user rotates the magnetic ring that is coupled to the magnetic sensor. This intermediary mechanism allows for reliable input on small screens by providing a larger, more stable interaction interface that is not susceptible to the same false triggering issues as direct touchscreen interaction.

AI summary
The present invention disclose an information processing method and a mobile device. The mobile device includes a device body and a magnetic adjustment mechanism, where the magnetic adjustment mechanism includes a magnetic adjustment member and a magnetic sensor, and the magnetic adjustment member is adjusted to enable the magnetic sensor to generate a pulse signal; and the device body further includes a processor and a display screen, and the processor receives the pulse signal generated by the magnetic adjustment mechanism, processes the pulse signal, and then displays adjusted content by using the display screen. This avoids a problem that adjustment cannot be conveniently performed because a display screen is covered by a finger when an operation is performed directly on the display screen.
