Common Base for Manual and Electric Vehicle Door Mirrors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for vehicle door mirrors cannot accommodate both manually retractable and electrically retractable configurations using a common base, as they are designed for specific shaft placements, limiting versatility and efficiency in manufacturing.
Innovation Solution
A common base design that includes a car body fixing section, a rotation support section, an upright shaft fastening surface, a center hole, and an annular wall housing groove, allowing the same base to support both manually retractable and electrically retractable door mirrors by adjusting the shaft placement and incorporating a clutch mechanism for stable positioning and reduced diameter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a common base is designed to accommodate both manually retractable and electrically retractable door mirrors with different shaft placements, then versatility and manufacturing efficiency are improved, but the base structure becomes more complex
Solution Approach 1:
The base is designed with a universal structure that can accommodate both manually retractable and electrically retractable door mirrors. The rotation support section includes a center hole and upright shaft fastening surface that can work with either shaft placement configuration, allowing one base design to serve multiple functions for different door mirror types.
Solution Approach 2:
The base incorporates dynamic adaptability through its rotation support section, which can dynamically adjust to support different shaft placements. The center hole allows passage of the second shaft for manual retractable mirrors, while the upright shaft fastening surface can fasten the first shaft for electrically retractable mirrors, enabling the base to dynamically adapt to different operational modes.
2Ease of manufacture
If the base structure is simplified for manufacturing, then manufacturing costs and complexity are reduced, but the rigidity and bearing capacity may be compromised
Solution Approach 1:
The base is segmented into distinct functional sections: the car body fixing section and the rotation support section. This segmentation allows each section to be optimized independently - the fixing section provides structural strength and rigidity for mounting, while the rotation support section provides the necessary bearing capacity for shaft rotation, simplifying manufacturing while maintaining overall structural integrity.
Solution Approach 2:
Different parts of the base have different local qualities optimized for their specific functions. The car body fixing section has high rigidity and strength properties for secure mounting, while the rotation support section has precise geometric features (center hole, upright shaft fastening surface) optimized for shaft support and rotation. This local optimization allows simplified manufacturing overall while maintaining necessary strength where required.
3Ease of manufacture
If the shaft placement is fixed for a specific door mirror type, then the design and manufacturing process is simplified, but the applicability to other door mirror types is limited
Solution Approach 1:
The base incorporates universal mounting features that can accommodate both shaft placement configurations. The rotation support section includes both a center hole for second shaft passage and an upright shaft fastening surface for first shaft mounting, allowing the same base design to be universally applied to both manually retractable and electrically retractable door mirrors without requiring type-specific variations.
Solution Approach 2:
The base design dynamically adapts to different shaft placement requirements through its dual-capability rotation support section. Depending on the door mirror type being installed, the base can be configured to use either the center hole configuration or the upright shaft fastening surface configuration, providing dynamic adaptability while maintaining a single standardized base design for manufacturing.

AI summary
The present invention provides a base which can be used for both manually retractable vehicle door mirror in which a shaft is placed on a rotating side and electrically retractable vehicle door mirror in which a shaft is placed on a stationary side. A base includes a car body fixing section and rotation support section. The rotation support section is equipped with an upright shaft fastening surface on which a shaft of an electric drive mechanism of an electrically retractable door mirror is fastened upright. A center hole is formed in a central part of the upright shaft fastening surface to rotatably pass a shaft formed on a rotating side of a manually retractable door mirror. An annular wall housing groove is formed on an outer circumferential side of the upright shaft fastening surface to rotatably house an annular wall formed coaxially with the shaft on the rotating side of the manually retractable door mirror.
