Electronic Rear-View Mirror with Rotary Push Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic rearview mirrors lack intuitive and user-friendly methods for adjusting the viewing angle and image detail of exterior cameras, which can lead to driver distraction and discomfort during adjustments.
Innovation Solution
Incorporating a mirror operator control element, such as a rotary/push control with additional degrees of freedom, allows drivers to adjust the image detail and camera orientation using familiar controls, including knobs, joysticks, trackballs, or touchpads, providing intuitive and distraction-free interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a swivel device is used to adjust the camera angle, then the viewing angle can be changed, but the device complexity increases
Solution Approach 1:
The patent replaces the mechanical swivel device with an electronic/image processing solution. Instead of physically moving the camera to change viewing angles, the system captures a wide-angle image and uses image processing to display different portions of the captured scene on the mirror surface, effectively substituting mechanical adjustment with electronic control.
Solution Approach 2:
The patent transitions from one-dimensional mechanical camera rotation to two-dimensional image selection and display control. By capturing a broad field of view and selectively displaying different regions of the captured image, the system adds a dimension of control through image processing rather than physical movement.
2Ease of operation
If automatic adjustment of the viewing angle is implemented, then the adjustment process is simplified, but driver interaction and control are reduced
Solution Approach 1:
The patent incorporates driver feedback mechanisms that allow the driver to interact with and control the mirror adjustment. The system can detect driver actions (such as hand position or control inputs) and adjust the displayed image portion accordingly, maintaining driver engagement while enabling automatic adjustment capabilities.
Solution Approach 2:
The system provides self-service automatic adjustment based on detected driving conditions or driver preferences, while simultaneously maintaining the capability for direct driver control when needed. This dual approach allows the system to operate autonomously when appropriate while remaining responsive to driver input.
3Ease of operation
If a rotary/push control is used for adjustment, then the ease of operation improves, but the device complexity increases
Solution Approach 1:
The patent employs a rotary/push control element that serves multiple functions: it can rotate to adjust horizontal viewing angles, push to adjust vertical angles or zoom levels, and potentially combine both motions for complex adjustments. This multi-functional control element consolidates what would otherwise require separate controls for different adjustment dimensions.
Solution Approach 2:
The patent combines multiple control functions (rotation for one axis, pushing for another axis) into a single integrated control element. This merging of control mechanisms into one unified interface simplifies the driver's interaction while managing the complexity through functional integration rather than separate controls.

AI summary
A motor vehicle has at least one electronic rearview mirror, particularly an exterior and/or side mirror, that has a display apparatus, particularly a display, for images recorded by an exterior camera that is provided particularly outside the motor vehicle. The operator control element provided for adjusting an image detail from the image, which image detail is to be displayed on the display apparatus, and/or an orientation for the exterior camera is a mirror operator control element, developed for the purpose of adjusting a mirror face of a conventional exterior mirror, and/or a rotary/push control of a man/machine interface.
