Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the camera is attached with suction cups on the windshield or with screw connections on bodywork, then the camera can be securely fixed, but the installation is complex and only enables recordings of certain objects
Solution Approach 1:
The mounting device is divided into separate modular components: a fastening device that attaches to the headrest holder and a support arm with carrier that can be independently positioned. This segmentation allows simple installation of the base component while maintaining secure fixation, eliminating the need for complex windshield suction cup installations or bodywork modifications.
Solution Approach 2:
The headrest holder mounting interface is designed to be universal, fitting various vehicle seat types. The support arm incorporates multiple joints (swivel joint with vertical axis, double joint with horizontal and vertical axes) that enable the same device to record various objects including interior scenes, exterior views through windshield, blind spots, and rear seat areas, replacing multiple specialized mounting solutions.
2Reliability
If the camera is attached with suction cups on the windshield or with screw connections on bodywork, then the camera can be securely fixed, but the installation is time-consuming and difficult to remove
Solution Approach 1:
The support arm incorporates dynamic elements including a swivel joint with vertically aligned axis of rotation and a double joint with horizontally and vertically aligned axes of rotation. These dynamic joints allow quick adjustment of the carrier position to capture various recording angles without requiring time-consuming reinstallation, while the fastening device maintains secure attachment to the headrest holder.
3Device complexity
If the camera is fixed in a specific position, then the installation is simple, but the camera cannot be adjusted for various recordings of different objects
Solution Approach 1:
The support arm incorporates dynamic elements including a swivel joint with vertically aligned axis of rotation and a double joint with horizontally and vertically aligned axes of rotation. These dynamic joints allow quick adjustment of the carrier position to capture various recording angles without requiring time-consuming reinstallation, while the fastening device maintains secure attachment to the headrest holder.
Solution Approach 2:
The mounting device allows continuous adjustment of multiple parameters: the vertical angle via the swivel joint, the horizontal angle via the double joint, and the distance from the mounting point via the extendable support arm. These parameter changes enable the same simple installation to achieve versatile recording positions for different objects and scenarios.
4Stability of the object's composition
If the camera is mounted on fixed structures, then the installation is stable, but passengers are at risk of injury in the event of an accident
Solution Approach 1:
The support arm functions as a flexible mounting structure that can absorb impact forces through its articulated joints. The swivel joint with vertical axis and double joint with horizontal and vertical axes provide degrees of freedom that allow the arm to move and dissipate energy during collisions, reducing the transmission of harmful forces to passengers compared to rigid fixed mountings.
Solution Approach 2:
The support arm acts as an intermediary element between the fixed headrest holder mounting and the camera. This intermediate flexible connection allows the mounting to remain stable while the arm absorbs and redirects forces during accidents, protecting passengers from injury while maintaining mounting stability.
5Device complexity
If the camera is mounted in fixed positions, then the installation is straightforward, but the camera is exposed to damage and dirt
Solution Approach 1:
The support arm incorporates dynamic elements including a swivel joint with vertically aligned axis of rotation and a double joint with horizontally and vertically aligned axes of rotation. These dynamic joints allow quick adjustment of the carrier position to capture various recording angles without requiring time-consuming reinstallation, while the fastening device maintains secure attachment to the headrest holder.
Solution Approach 2:
The headrest holder mounting interface is designed to be universal, fitting various vehicle seat types. The support arm incorporates multiple joints (swivel joint with vertical axis, double joint with horizontal and vertical axes) that enable the same device to record various objects including interior scenes, exterior views through windshield, blind spots, and rear seat areas, replacing multiple specialized mounting solutions.
