Automatically Adjustable Vehicle Back View Mirror with Multi-DOF Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle back view mirrors have fixed positions and lack intelligent control, limiting their adjustment to specific scenes and reducing efficiency in voice interaction, as they can only be manually adjusted in one rotation direction, which restricts their applicability and field of view.
Innovation Solution
An automatically adjustable back view mirror device with a translation actuating device for positioning in multiple directions and a rotating actuating device for adjusting the mirror's orientation, driven by electric, gas, or hydraulic cylinders and motors, using image collector data to determine and implement precise adjustments based on the driver's face image information and voice instructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the back view mirror has a fixed position, then the device complexity is reduced, but the adaptability and field of view are limited
Solution Approach 1:
The back view mirror is transformed from a fixed static structure to a dynamic adjustable structure. Translation actuators enable the mirror to move in multiple directions (up-down, left-right, forward-backward), while rotation actuators allow inclination and azimuth adjustments. This dynamic capability resolves the contradiction by providing adaptability through multi-degree-of-freedom movement while maintaining manageable device complexity through modular actuator design.
Solution Approach 2:
The back view mirror system is designed to perform multiple functions: it can translate in three directions and rotate about two axes, allowing it to adapt to different vehicle types, driving positions, and viewing requirements. This multi-functionality resolves the adaptability contradiction by making a single mirror system universally applicable to various scenarios rather than requiring multiple fixed mirrors for different configurations.
2Adaptability or versatility
If the back view mirror allows manual adjustment in one rotation direction, then the ease of operation is improved, but the adaptability and field of view remain limited
Solution Approach 1:
The mirror system incorporates multiple degrees of freedom with independent actuators: translation in three directions and rotation about two axes. This dynamic multi-DOF design expands the field of view significantly compared to single-direction adjustment, resolving the adaptability contradiction while keeping each actuator module relatively simple and independent.
Solution Approach 2:
The adjustment system is segmented into independent functional modules: translation actuators for positional adjustment and rotation actuators for orientation adjustment. Each module handles a specific degree of freedom, which resolves the complexity issue by allowing independent optimization and control of each adjustment function rather than requiring a complex integrated mechanism.
3Extent of automation
If the back view mirror lacks intelligent control, then the device complexity is reduced, but the efficiency of voice interaction and automation are low
Solution Approach 1:
The back view mirror system incorporates voice recognition and image collection capabilities that enable automatic adjustment without manual intervention. The system can autonomously interpret voice commands or image data and translate them into appropriate mirror positioning and orientation, resolving the automation contradiction by making the system self-sufficient in adapting to driver needs while maintaining manageable complexity through standardized interfaces between components.
Solution Approach 2:
The system uses image collectors to capture driver face information and voice receivers to detect commands, providing feedback loops that enable intelligent automatic adjustment. This feedback mechanism resolves the automation contradiction by allowing the system to sense driver intent and automatically adjust the mirror accordingly, enhancing automation while keeping device complexity manageable through modular sensor and controller integration.
