Touchpad Dial Interface Using Translucent Light Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch pads in electronic devices lack sufficient functionality and internal space for incorporating a dial mechanism, limiting user interaction and functionality.
Innovation Solution
A touch control module with a translucent dial pattern and light-emitting elements on a touch pad that projects a light-emitting pattern to simulate a dial function, enhancing user interaction without occupying additional space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a physical dial is provided in the electronic product, then dial function is achieved, but internal space becomes insufficient
Solution Approach 1:
The patent creates a virtual dial interface on the touch pad surface that visually replicates the appearance and functionality of a physical dial without occupying actual space. The dial pattern including inner circle and outer ring regions is displayed on the touch surface, allowing users to interact with a dial-like interface through touch gestures while conserving internal device space.
Solution Approach 2:
The patent transitions the dial function from a three-dimensional physical component to a two-dimensional graphical interface on the touch pad. By projecting the dial pattern onto the touch surface and using light-emitting elements to create visual effects, the system achieves dial functionality in the visual dimension rather than requiring physical depth and volume.
2Adaptability or versatility
If existing touch pad functions are used, then simple cursor operation is achieved, but user interaction functionality is insufficient
Solution Approach 1:
The patent enhances the touch pad to serve multiple functions: it maintains basic cursor navigation capabilities while adding dial operation functionality. The touch pad can detect both simple tap gestures for cursor movement and rotational touch patterns for dial control, allowing a single device to perform both simple and complex interaction tasks.
Solution Approach 2:
The patent uses light-emitting elements that change color or illumination patterns to provide visual feedback during dial operations. Different colors or light patterns indicate different dial states or directions, making the interface more intuitive and easier to operate by providing clear visual cues for user interaction.
