Automobile Mirror Baseplate Provisional Fixation Hook
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual mounting of exterior mirror bases on motor vehicle doors is labor-intensive and costly, requiring precise alignment and force application, which can be difficult due to the absence of clear feedback during the press-fit engagement of fixing means.
Innovation Solution
An exterior mirror base with elastically deformable hooks that engage with the door's upper edge, allowing for a pivoting movement to position the base correctly for final fixing, facilitating easier alignment and reducing the need for precise horizontal force application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If manual mounting with press-fit fixing means is used, then the mirror base can be securely attached to the door, but the assembly process becomes labor-intensive and costly requiring precise alignment and force application
Solution Approach 1:
The attachment system is divided into two distinct phases: temporary attachment using hooks that engage with the door edge, and final secure attachment using press-fit fixing means. This segmentation allows the assembler to first easily position the mirror base using the hook mechanism, then complete the secure attachment, thereby reducing the overall assembly difficulty while maintaining strong attachment.
Solution Approach 2:
The hook mechanism performs the preliminary action of positioning and temporarily securing the mirror base to the door in the correct location before the final press-fit attachment is made. This preliminary positioning eliminates the need for precise alignment during the final attachment step, making the overall process easier and less labor-intensive.
2Manufacturing precision
If press-fit fixing means are used without clear feedback, then the mirror base can be attached, but precise force application becomes difficult due to absence of clear feedback
Solution Approach 1:
The hook mechanism provides immediate tactile and visual feedback when properly engaged with the door edge, allowing the assembler to confirm correct positioning and engagement. This feedback mechanism eliminates the uncertainty associated with press-fit operations where clear feedback is absent, enabling precise positioning before the final attachment.
3Manufacturing precision
If manual alignment and positioning is performed, then the mirror base can be correctly positioned, but productivity is hindered and additional labor costs are incurred
Solution Approach 1:
The hook mechanism is designed to automatically guide and position the mirror base onto the door edge through its geometric configuration. The assembler simply needs to engage the hook with the door edge, and the mechanism itself ensures correct positioning without requiring additional manual alignment operations. This self-positioning capability significantly improves assembly speed while maintaining positioning accuracy.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution simplifies the mounting process, reduces labor costs, and ensures accurate positioning of the mirror base, enabling quicker assembly and more economical manufacturing by providing temporary support and maintaining the base vertically during screw engagement.

AI summary
The invention relates to a base (14) for a side view mirror on a motor vehicle door (2), comprising an attachment portion (18) for attachment to a generally vertical door panel (12), means of temporarily attaching the attachment portion to the door, said means including first temporary attachment means (24) located in an upper region (26) of the base, and a hook (24'). The hook is located at a lower edge (26') of the base and extends downwards in such a way as to be able to engage an upper edge (6) of an outer door panel (4) as the first means perform an engaging movement that is followed by a pivoting movement of the base in order to engage said hook. The invention also relates to a door comprising a side view mirror base of said type.
