Vehicle Viewing Assembly Joint for Simpler Angle Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing viewing means assemblies for motor vehicles, such as mirrors and cameras, have complex and multi-part constructions that lead to high production and storage costs, as well as complex assembly processes.
Innovation Solution
A simplified device for adjusting viewing means assemblies using a joint assembly that allows the support frame to rotate relative to the base part about a first joint axis and pivot relative to the installation frame about a second joint axis, with a sliding ring providing a plain bearing to reduce wear and facilitate movement, reducing the number of required joint components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a complex multi-part construction with multiple joint assemblies is used to enable viewing means adjustment, then the viewing angle and position can be adapted to operator requirements, but the device complexity, production costs, and assembly complexity increase significantly
Solution Approach 1:
The patent combines multiple joint assemblies into a single integrated joint assembly that contains both the first joint axis (A1) for rotation and the second joint axis (A2) for pivoting. This merging of previously separate joint assemblies reduces the overall number of components, simplifies the structure, and lowers production and assembly costs while maintaining the full range of motion required for viewing means adjustment
Solution Approach 2:
The single joint assembly serves multiple functions by providing both rotational movement about axis A1 and pivoting movement about axis A2 through integrated bearing assemblies. This multi-functional design eliminates the need for separate joint assemblies for each degree of freedom, thereby reducing device complexity while preserving adaptability
2Adaptability or versatility
If multiple separate joint assemblies are used to enable rotation and pivoting movements, then the viewing means can be positioned flexibly, but the number of parts increases leading to higher production and storage costs
Solution Approach 1:
The patent merges multiple separate joint assemblies into one integrated joint assembly that provides both rotational and pivoting capabilities. This consolidation reduces the total number of parts from multiple separate assemblies to a single unified structure, thereby lowering production and storage costs while maintaining positioning flexibility
3Ease of operation
If traditional joint assemblies with multiple components are used, then the viewing means can be adjusted, but the assembly process becomes time-consuming and complex
Solution Approach 1:
By combining multiple joint assemblies into a single integrated unit, the patent reduces the number of assembly steps required. Instead of assembling and aligning multiple separate joint assemblies, the manufacturer only needs to install one integrated joint assembly, significantly simplifying the assembly process and reducing manufacturing time
4Measurement precision
If multiple joint assemblies with various bearing components are used, then the viewing means can be positioned accurately, but wear and maintenance requirements increase
Solution Approach 1:
The integrated joint assembly reduces the total number of bearing surfaces and contact points compared to multiple separate joint assemblies. Fewer components mean fewer surfaces subject to wear, thereby improving reliability and reducing maintenance requirements while maintaining positioning accuracy through the precision-engineered single joint structure

Function Achieved in This Case
The solution results in a more cost-effective, durable, and less complex device with reduced wear and easier assembly, while maintaining the ability to adjust the viewing angle and position of the viewing means.
Implementation Method 1
at least one sliding ring is optionally arranged between the joint head and the intermediate socket, which sliding ring forms a plain bearing between the joint head and the intermediate socket by means of which the installation frame can be slidably rotated relative to the base part about the first joint axis A1 and about the second joint axis A2

AI summary
The invention relates to a device for adjusting a viewing means assembly, comprising an installation frame and a support frame arranged together on a base part by means of a first joint assembly. The installation frame is further arranged on the support frame by means of a second joint assembly. The installation frame can be rotated relative to the base part only about a first pivot axis and pivoted relative to the support frame only about a second joint axis transverse to a first joint axis. The first joint assembly comprises a joint body bearing assembly. The second joint assembly comprises a counter bearing assembly, comprising at least one bearing means and at least one complementary counter bearing means, which can be guided together in a sliding manner such that the installation frame can be pivoted relative to the support frame only about the second joint axis.
