Rotary Ring Screen Operating System with Magnetic Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen-based vehicle operating systems with mechanical operating elements face challenges in minimizing the blocking or covering of the display field, as conventional rotary knobs protrude significantly, obstructing the screen and limiting usable display area.
Innovation Solution
A screen-based operating system with a rotary ring mechanical operating element, where one part is flush-mounted axially within the housing and the other part protrudes, utilizing a magnet arrangement for stable support and haptic feedback, minimizing screen obstruction and incorporating a cradle for mobile devices with magnetic latching and sensing for enhanced interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional rotary knobs are used as mechanical operating elements, then haptic feedback and stable support are achieved, but the display field is significantly blocked or covered
Solution Approach 1:
The rotary ring is segmented into a first part that is mounted axially into the housing and a second part that extends out of the housing. This segmentation allows the operating element to provide stable support through the first part while minimizing display field blocking with the extended second part.
Solution Approach 2:
The rotary ring extends in the axial dimension rather than purely radially outward. By mounting one part axially into the housing and having the other part extend above the screen, the design utilizes the third dimension (depth/axial direction) to achieve stable support without maximizing radial projection that would block the display.
2Ease of operation
If mechanical operating elements protrude into the display field, then haptic feedback is provided, but the usable display area is reduced
Solution Approach 1:
The rotary ring has different functional zones: the first part mounted axially into the housing provides stable support and haptic feedback through magnetic interaction, while the second part extending above the screen provides minimal obstruction. This local differentiation optimizes both haptic operation and display visibility.
Solution Approach 2:
The patent replaces traditional mechanical contact-based haptic feedback with magnetic field interaction between magnet arrangements in the rotary ring and housing. This substitution provides haptic feedback through magnetic forces while allowing the rotary ring to have a more compact profile that blocks less of the display.
3Area of stationary object
If a compact mechanical operating element is used, then display field blocking is minimized, but stable support and haptic feedback may be compromised
Solution Approach 1:
Magnet arrangements are introduced as an intermediary mechanism between the rotary ring and the housing. These magnets provide the necessary magnetic field interaction to generate haptic feedback and stable support without requiring the mechanical operating element to have a large physical footprint, thus minimizing display blocking.
Solution Approach 2:
The rotary ring incorporates magnet arrangements within its structure, creating a composite element that combines mechanical functionality with magnetic field generation. This allows the operating element to maintain a compact size while providing both stable support through mechanical mounting and haptic feedback through magnetic interaction.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution allows for minimal obstruction of the screen while providing effective haptic feedback and stable support, enabling efficient operation and display usage with reduced visual obstruction and enhanced user interaction.
Implementation Method 1
The housing may include a magnet arrangement and the rotary ring may include another magnet arrangement. The magnet arrangements cooperate through magnetic field interaction to generate mechanical latching, and thereby haptic feedback, when the rotary ring rotates.

AI summary
A screen-based operating system includes a housing having a screen accommodated therein and a rotary ring rotatably mounted to the housing. A first part of the rotary ring is mounted axially into the housing and a remaining second part of the rotary ring extends out of the housing and above the screen.
