Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple sizes of sun visors are designed to fit different vehicle types, then the sun visors can be properly sized for each vehicle, but the design and installation costs increase and complexity increases
Solution Approach 1:
The sun visor assembly is designed with a universal mounting system that can accommodate different vehicle sizes through a single design. The bracket and pivot arm mechanism can be configured in multiple positions and orientations, allowing the same visor assembly to fit various vehicle types without requiring multiple specialized designs.
Solution Approach 2:
The sun visor assembly incorporates movable and adjustable components including a pivot arm with multiple degrees of freedom, allowing the visor to be dynamically positioned and mounted in different configurations. This dynamic adjustability enables a single visor design to adapt to different vehicle interiors and window positions.
2Adaptability or versatility
If multiple sizes of sun visors are designed to fit different vehicle types, then the sun visors can be properly sized for each vehicle, but production costs increase
Solution Approach 1:
By designing a universal sun visor assembly that can serve multiple vehicle types, the manufacturer produces only one size of visor rather than multiple sizes. This universality reduces production costs through economies of scale while maintaining adaptability through the adjustable mounting system.
Solution Approach 2:
The sun visor system is segmented into separate functional components (visor blade, bracket, pivot arm, mounting mechanism) that can be manufactured independently and then assembled. This segmentation allows for standardized mass production of each component while maintaining overall system adaptability.
3Ease of manufacture
If a single visor design is used for all vehicle sizes, then production costs decrease and design complexity reduces, but the visor may not fit all vehicle types properly
Solution Approach 1:
The mounting system incorporates dynamic, adjustable components that allow a single visor design to adapt to different vehicle sizes. The pivot arm can be positioned at various angles and distances from the mounting bracket, enabling proper fit across different vehicle types without requiring multiple visor designs.
Solution Approach 2:
The system allows for parameter changes in the mounting configuration (distance from windshield, angle of visor, position of pivot arm) to accommodate different vehicle sizes. By varying these parameters rather than changing the entire visor design, the system maintains manufacturing simplicity while achieving proper fit.

AI summary
A sun visor assembly comprising a first arm coupled to a bracket and configured to rotate about a first axis and a second axis and a second arm coupled to the first arm with a hinge. A third axis extends through the second arm and a fourth axis extends through the hinge, the second arm being configured to rotate with respect to the first arm about the fourth axis. A visor is selectively coupled to the first arm and is rotatably coupled to the second arm, the visor being configured to rotate about the third axis.
