Rotary Wheel Control for Compact Watch Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Watch-type terminals have limited size, restricting the types of controls that can be implemented, particularly for navigating and interacting with visual information displayed on their small screens.
Innovation Solution
A watch-type terminal that uses a wheel surrounding the outer side of its body, allowing users to control visual information by turning the wheel, enabling navigation and execution of control commands through rotational inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a touch button or push button is used to control visual information on a watch type terminal, then the control functionality is provided, but the device size increases and the limited space constraint is violated
Solution Approach 1:
The wheel component serves multiple functions: it can be rotated to navigate menus, pressed to select items, and combines scrolling with selection capabilities. This multi-functionality eliminates the need for separate buttons, providing full control functionality while maintaining a compact device size.
Solution Approach 2:
The invention merges the navigation function (scrolling) and selection function (button press) into a single wheel component. By combining these previously separate functions into one element, the device maintains comprehensive control capabilities without requiring additional space for multiple discrete buttons.
2Area of stationary object
If the watch type terminal is kept compact with limited size, then the device portability is improved, but the control options are restricted
Solution Approach 1:
The wheel provides dynamic control capabilities through rotational movement for scrolling and pressing for selection. This dynamic interaction allows the compact device to offer versatile control options that adapt to different user needs, such as navigating through lists, selecting items, and accessing menus, all within a limited space.
Solution Approach 2:
The single wheel component performs multiple control functions including scrolling, selecting, and navigating, making the compact watch terminal versatile despite its limited size. This multi-functional design ensures that no critical control option is sacrificed due to space constraints.
3Adaptability or versatility
If multiple buttons are added to provide comprehensive control, then the control versatility is improved, but the device complexity increases
Solution Approach 1:
The wheel is designed as a universal control element that handles multiple operations: rotation for scrolling through options, pressing for selection, and potentially combination movements for different functions. This single multi-functional component reduces device complexity compared to implementing separate buttons for each control function.
Solution Approach 2:
The invention merges navigation and selection controls into one wheel mechanism, reducing the total number of components needed. This consolidation simplifies the device structure while maintaining comprehensive control versatility, avoiding the complexity that would arise from adding multiple discrete buttons.
