Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-size luggage bracket is used, then the structure is simple, but it cannot adapt to different car roof sizes
Solution Approach 1:
The patent implements adjustability through a dynamic structure where the support arm can change its length and angle. The support arm includes an adjustable section with telescopic components that allow it to extend or retract, and a rotating section that enables angular adjustment. This dynamic design allows the same bracket to adapt to different car roof sizes and shapes without requiring multiple fixed-size brackets.
Solution Approach 2:
The bracket utilizes parameter changes by allowing the support arm to vary its length and orientation angle. The adjustable section changes the length parameter through telescopic movement, while the rotating section changes the orientation parameter. These parameter variations enable the bracket to accommodate different installation positions and roof geometries, solving the adaptability problem.
2Adaptability or versatility
If an adjustable hook mechanism is used, then universality is improved, but the device complexity increases
Solution Approach 1:
The support arm is segmented into multiple functional sections: a fixed section, an adjustable section with telescopic components, and a rotating section with a hook mechanism. This segmentation allows each part to perform its specific function independently, making the overall system more manageable despite the increased complexity. The modular design facilitates easier adjustment and maintenance.
Solution Approach 2:
The bracket is designed with multi-functional capabilities through its adjustable and rotating components. The same bracket can be installed on various car models with different roof dimensions by adjusting the support arm length and angle. The hook mechanism can engage with different mounting points, providing universal applicability across different vehicle types.
3Adaptability or versatility
If multiple adjustment components are added, then compatibility with various car models is improved, but manufacturing complexity increases
Solution Approach 1:
The bracket employs dynamic adjustment mechanisms that allow post-manufacturing flexibility. The adjustable section with telescopic components and the rotating section with angular adjustment enable the bracket to be configured for different car models after production. This reduces the need for manufacturing multiple fixed-size brackets, thereby lowering overall manufacturing complexity despite the presence of adjustment components.
