Vehicle Door Mirror Assembly Method Single-Direction Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional manually and electrically retractable vehicle door mirrors require complex and difficult-to-automate assembly operations due to the need for assembly from multiple directions.
Innovation Solution
A vehicle door mirror assembly method that allows for assembly from a single direction using a housing support member, housing, and base components with specific screw and spring member configurations, enabling ease of assembly and automation by using a housing support member placement space, screw holes, and a spring member to secure the components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If conventional assembly methods are used for door mirrors, then the structural integrity and functionality are maintained, but the assembly operations become complicated and difficult to automate due to assembly from multiple directions
Solution Approach 1:
The patent inverts the conventional assembly approach by having components assemble from a single direction (front to rear) rather than requiring assembly from multiple directions. The housing support member is positioned first, then the housing is attached to it, and finally the base is attached to the housing, creating a linear unidirectional assembly sequence that simplifies automation.
Solution Approach 2:
The door mirror assembly is divided into distinct modular components (housing support member, housing, base) that can be independently manufactured and then assembled in a standardized sequence. This segmentation allows each component to be optimized independently while enabling simplified automated assembly through consistent interface designs.
2Productivity
If assembly operations are performed from various directions as in conventional door mirrors, then all components can be properly positioned and secured, but the assembly operations become complicated and time-consuming
Solution Approach 1:
The housing support member is prepared and positioned in advance before the housing and base are attached. This preliminary positioning establishes a standardized starting point for subsequent assembly operations, eliminating the need for complex multi-directional alignment and reducing overall assembly time.
Solution Approach 2:
Instead of assembling components from multiple directions simultaneously as in conventional methods, the patent inverts the approach by establishing a single primary assembly direction (front to rear). This inversion transforms a complex multi-step process into a simpler sequential process, improving productivity while reducing assembly time.

AI summary
The present invention provides a door mirror and assembly method therefor with improved assembly performance. A housing support member, housing, and base of a manually retractable door mirror are assembled using screws, a coil spring, and a plate. During assembly, the housing support member is supported in an upside-down position by a jig, and the housing and base are placed in sequence in an upside-down position on the housing support member from above. An electric drive mechanism, fitting, housing, and base of an electrically retractable door mirror are assembled using screws. During assembly, the electric drive mechanism is supported in an upside-down position by a jig, and the fitting, housing, and base are placed in sequence in an upside-down position on the electric drive mechanism from above.
