Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If exterior mirrors are replaced with cameras for aerodynamic reasons, then aerodynamic performance is improved, but comprehensive surroundings monitoring capability deteriorates
Solution Approach 1:
The patent combines multiple cameras (first camera for rearview, second camera for surroundings monitoring) into a single integrated equipment holder unit. This merging allows the system to maintain aerodynamic efficiency with a streamlined housing while achieving comprehensive monitoring capabilities through multiple sensor functions within one structure.
Solution Approach 2:
The equipment holder is designed as a multi-functional unit that simultaneously provides rearview mirror functionality (first camera), surroundings monitoring (second camera), and can accommodate additional sensors. This universal design ensures that a single aerodynamic structure delivers multiple monitoring functions, resolving the contradiction between streamlined design and comprehensive sensing capability.
2Adaptability or versatility
If multiple sensors are arranged separately on the vehicle, then each sensor can be optimized for its function, but device complexity and aerodynamic optimization deteriorate
Solution Approach 1:
Multiple sensors (first camera, second camera, and additional sensors) are merged into a single equipment holder assembly. This integration reduces the overall number of separate components and mounting locations, simplifying the device while maintaining the ability to optimize each sensor's function through dedicated positioning within the unified structure.
Solution Approach 2:
The equipment holder is designed as a modular platform that can accommodate different sensor types and configurations. Each sensor can be independently positioned and optimized within the segmented housing structure, allowing functional optimization while maintaining overall system simplicity through standardized mounting interfaces.
3Loss of energy
If the housing is positioned close to the vehicle for aerodynamic reasons, then aerodynamic noise is reduced, but the camera's ability to see the widest point of the vehicle deteriorates
Solution Approach 1:
The first camera is positioned in the equipment holder with its optical axis oriented at an angle relative to the vehicle's longitudinal axis, rather than directly backward. This angular positioning in a different dimensional orientation allows the camera to see around the widest point of the vehicle while the housing remains close to the vehicle body for aerodynamic efficiency.
Solution Approach 2:
The equipment holder provides a locally optimized mounting position and orientation for the first camera, distinct from the overall housing position. The housing can be aerodynamically integrated close to the vehicle, while the camera within it is locally positioned and angled to achieve the necessary viewing geometry for seeing the widest point.

AI summary
An equipment holder is provided for a vehicle. The equipment holder includes a first camera, a second camera, and a housing for receiving the cameras. The housing is configured to be attached to a right-hand side or left-hand side exterior part of the vehicle so that the first camera can view an area behind and to the side of the vehicle and the second camera can view an area to the side of the vehicle.
