Exterior Rear View Mirror Frame Assembly for Unrestricted Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing assembly processes for exterior rear view mirrors in motor vehicles are complex, time-intensive, and costly due to poor accessibility of mechanical and electrical connections through the rear-facing opening surrounded by the frame, leading to inefficient production and assembly.
Innovation Solution
An exterior rear view mirror design where the frame surrounding the mirror glass is attached to the base bracket using the adjusting device, allowing for easier alignment and attachment, and the frame is designed with a bowl-shaped section for secure attachment, providing unrestricted accessibility for connections and weight savings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the frame surrounds the opening on the rear side of the exterior rear view mirror housing, then the mirror glass edges are protected and safety regulations are met, but accessibility to mechanical and electrical connections becomes poor
Solution Approach 1:
The frame is divided into a first frame part and a second frame part that can be moved relative to each other. The second frame part can be displaced from a blocking position to a non-blocking position, allowing accessibility to connections while maintaining protection when needed. This segmentation allows the frame to perform both protective and accessible functions at different times.
Solution Approach 2:
The frame transitions from a static structure to a dynamic one where the second frame part can move between positions. This dynamic capability allows the frame to adapt its configuration based on operational requirements - providing protection during normal operation and allowing access during assembly or maintenance.
2Object-affected harmful factors
If traditional assembly processes are used with frame surrounding the opening, then safety requirements are met, but assembly time increases and productivity decreases
Solution Approach 1:
The first frame part is pre-assembled with the housing and base bracket before the second frame part is attached. This preliminary assembly allows connections to be established more efficiently, reducing overall assembly time while still maintaining safety compliance through the complete frame structure.
Solution Approach 2:
By segmenting the frame into two parts that can be assembled separately and then connected, the assembly process becomes more efficient. The first frame part can be installed without blocking access to certain areas, and the second frame part is added subsequently to complete the protective structure.
3Stability of the object's composition
If the frame is attached separately from the adjusting device, then structural independence is maintained, but device complexity and assembly steps increase
Solution Approach 1:
The attachment of the frame to the base bracket is merged with the attachment of the adjusting device to the base bracket. Both components are secured to the base bracket simultaneously using the same fastening elements, reducing the number of separate assembly steps while maintaining the structural independence of each component.
