Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing complexity of electronic devices in vehicles requires compact control elements that provide a high degree of functionality, as larger displays reduce available space and using multiple control elements can distract drivers.
Innovation Solution
A multifunctional rotary switch with bidirectional rotational, translational, and pushing modes of operation, where electrical switches are arranged inside the roller to maintain compactness and allow intuitive operation, enabling access to various functions of electronic devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple control elements are used to provide various functions, then the degree of functionality is improved, but the amount of space required increases
Solution Approach 1:
The patent combines three distinct control operations (rotational, translational, and pushing modes) into a single roller control element. The roller can rotate bidirectionally around an axis, translate parallel to the axis, and be pushed perpendicular to the axis, integrating multiple control functions that would traditionally require separate buttons or switches into one compact component.
Solution Approach 2:
The roller control element is designed to perform multiple functions through different operational modes. The same physical component responds to rotational input for one set of functions, translational input for another set, and pushing input for a third set, making it a universal control element that replaces multiple specialized controls.
2Adaptability or versatility
If multiple control elements are used to access various functions, then the degree of functionality is improved, but driver distraction increases
Solution Approach 1:
By merging multiple control operations into a single roller element, the patent reduces the number of discrete control actions a driver must perform. The driver interacts with one continuous component rather than switching between multiple separate buttons or switches, simplifying the control process and reducing cognitive load.
Solution Approach 2:
The universal roller control element allows a driver to access various functions through intuitive motions (rotate, push, slide) without needing to locate or remember the specific function of each separate control element, reducing distraction while maintaining comprehensive functionality.
