Solution Overview
Problem
Portable electronic devices face a challenge in balancing the need for comprehensive functionality with simplified control key configurations, leading to complex operations or limited functionality.
Innovation Solution
A portable electronic device equipped with a wheel that generates switching signals to navigate between first and second function options, allowing cyclic switching in the first function menu and endpoint switching in the second, facilitated by a processor that determines the current option and adjusts accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a large number of control keys are set to achieve complete functions, then the functionality of the device is improved, but the operation process becomes complicated
Solution Approach 1:
The wheel component is designed to perform multiple functions: it can rotate to switch between different function options, press to confirm selections, and serve as both a navigation and selection tool. This multi-functional design eliminates the need for separate control keys for different operations, simplifying the control interface while maintaining complete device functionality
Solution Approach 2:
The patent merges the functions of multiple control keys into a single wheel component. The wheel integrates directional navigation (rotation) and selection (pressing) capabilities that would traditionally require separate buttons, thereby reducing the total number of control elements while preserving full operational capability
2Ease of operation
If fewer control keys are used to simplify the interface, then the ease of operation is improved, but only relatively simple functions can be performed
Solution Approach 1:
The wheel interface employs dynamic switching between different operation modes (rotation for navigation, pressing for selection). This dynamic behavior allows a single static component to deliver multiple functional outcomes, enabling complex operations through simple, adaptive control actions rather than requiring multiple dedicated keys for each function
Solution Approach 2:
The control interface is segmented into distinct operational phases: rotation phase for browsing options and pressing phase for selection. This segmentation allows the single wheel to manage complex functionality by breaking down operations into discrete, manageable steps, maintaining simplicity while enabling sophisticated control capabilities
3Device complexity
If a single wheel is used for all control operations, then the device complexity is reduced, but the precision of control for different functions may be compromised
Solution Approach 1:
The wheel interface implements local quality by providing context-specific control behavior: rotation precision is optimized for navigating through options, while pressing provides precise selection confirmation. The system adapts the control precision characteristics to the specific operational context, ensuring high precision for each type of control action despite using a single unified component

AI summary
A portable electronic device (1) includes a wheel (11), a display (12) and a processor (13). The wheel (11) is configured to rotate to generate a positive/negative switching signal. The display (12) is configured to display a current option, which is one of a plurality of first/second function options. The processor (13) is electrically connected to the wheel (11) and the display (12), and is configured to switch the current option to last/first one of the first/second function options when receiving the negative/positive switching signal and determining that the current option is first/last one of the first function options; and not to switch the current option when receiving the negative switching signal and determining that the current option is first one of the second function options, or when receiving the positive switching signal and determining that the current option is last one of the second function options.
