Touch Screen Knob Device With Varying Height Pads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional touch monitor operation knobs have a complicated setting mechanism for touch control pads, requiring independent configuration before use, which is not conducive to implementation.
Innovation Solution
A knob device for touch screens featuring a base with recovery elastic components and an operating cap with touch control pads of varying heights, allowing for rotational and click controls without separate pad configuration, utilizing a bracket with mounting holes and auxiliary return components for flexible assembly and tactile feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If touch control pads are set independently before leaving the factory, then each pad can independently perform corresponding control functions, but the setting mechanism becomes complicated and is not conducive to implementation
Solution Approach 1:
The patent merges multiple touch control pads into a single integrated operating cap structure. Instead of having separately configured pads, all touch control functions are integrated into one cap that can perform rotation, pressing, and sliding operations, thereby simplifying the setting mechanism while maintaining versatile control capabilities
Solution Approach 2:
The operating cap is designed as a universal control interface that can perform multiple control functions (rotation for scrolling, pressing for selection, sliding for navigation) through a single component. This multi-functional design eliminates the need for separate independent pads and their complex individual configurations
2Adaptability or versatility
If multiple touch control pads are configured independently, then diverse control functions can be achieved, but the mechanism becomes complicated requiring coordination with structural design
Solution Approach 1:
Multiple control functions are merged into a single operating cap that integrates rotation, pressing, and sliding capabilities. This consolidation maintains diverse control functions while dramatically improving implementation ease by eliminating complex multi-pad coordination requirements
Solution Approach 2:
The operating cap employs dynamic mechanisms including elastic components that enable pressing detection, rotational movement for scrolling, and sliding capability for navigation. These dynamic features are integrated into one component, providing diverse control functions with simple implementation

AI summary
A knob device for disposing on a touch screen, comprising a base provided with a plurality of recovery elastic components; and an operating cap disposed on the base. The operating cap have a rotation stroke and a pressing stroke, and is provided with a plurality of touch control pads, each of the pads has a working surface. The working surface of at least one of the touch control pads is not at a same height as the working surfaces of the other touch control pads. When the rotation stroke is performed, the working surfaces of some of the touch control pads contact the touch screen to activate a rotational touch control. When the pressing stroke is performed, the working surfaces of the touch control pads contact the touch screen jointly to activate a click and touch control.
