Rear-view Mirror Camera Linear Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rear-view mirror units for vehicles have limitations in providing a comprehensive view, especially due to dead angles and obstacles like dirt or dew, and require complex actuation mechanisms that may compromise road safety and visibility.
Innovation Solution
A rear-view mirror unit with a semitransparent area housing a linearly movable camera equipped with wide-angle optics, allowing for improved visibility by adjusting its position vertically and horizontally, and incorporating a guide element for rotary movement, along with a connection cable for easy mounting and flexibility, without altering the vehicle's exterior appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a camera is positioned behind a mirror in a fixed position, then the structure is simple, but the visible area is limited and dead angles remain
Solution Approach 1:
The camera is made movable instead of fixed, allowing it to change position along a linear path behind the mirror. This dynamic positioning enables the camera to capture different areas and eliminate dead angles while maintaining a relatively simple linear movement mechanism rather than complex multi-axis positioning.
2Area of stationary object
If a swivelling mechanism is used to reposition the camera, then the visible area can be adjusted, but the actuation becomes complicated and road safety is compromised
Solution Approach 1:
The camera employs linear movement along a straight path rather than swivelling or rotational mechanisms. This simplifies the actuation system, reduces mechanical complexity, and improves reliability for road safety applications while still enabling the camera to reposition to capture different viewing areas.
3Stability of the object's composition
If the camera is permanently connected to the mirror unit, then the structure is stable, but mounting and dismounting becomes difficult
Solution Approach 1:
The connection between camera and mirror unit is segmented into separate components with a connecting element that can be easily attached and detached. This allows the camera to be mounted or dismounted from the mirror unit without requiring permanent fixation, facilitating maintenance, replacement, or adjustment while maintaining stable operation during use.
