Door Mirror Partition Wall Reinforcement for Assembly Efficiency

Solution Overview

Problem

Existing door mirrors have limitations in the size of the opening of the partition wall, which restricts the size of the terminal part and power supply connector, making it difficult to accommodate various mirror surface angle adjusting units with different shapes and sizes, and hinders assembling efficiency.

Innovation Solution

A door mirror design with a partition wall that includes reinforcing tube portions and ribs surrounding the opening, allowing for a larger opening size while maintaining structural integrity, enabling the use of a single mirror housing for multiple types of door mirrors with varying terminal parts and enhancing assembling efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the opening of the partition wall is enlarged, then the terminal part and power supply connector can be larger and more terminals can be concentrated, but the strength of the partition wall is reduced

Engineering Contradiction:
Core Design Contradiction:
ProductivityVSStrength

Solution Approach 1:

The partition wall is segmented by introducing multiple insertion through-holes surrounded by reinforcing tube portions, distributing the structural load away from the large opening while maintaining wall strength. This allows the opening to be enlarged without compromising overall structural integrity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The partition wall employs a composite structure combining the main wall material with reinforcing tube portions made of high-strength material. These reinforcing elements are strategically positioned around insertion through-holes to compensate for the strength reduction caused by the enlarged opening.

Inventive Principle:
Principle #40Composite materials

2Adaptability or versatility

If the opening of the partition wall is formed large, then one type of mirror housing can be applied to various mirror surface angle adjusting units, but the terminal part and power supply connector become larger

Engineering Contradiction:
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The mirror housing with the enlarged opening and specific partition wall structure serves as a universal component that can accommodate multiple types of mirror surface angle adjusting units with different terminal part configurations. The standardized housing design enables one housing type to be used across various door mirror models.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The terminal part and power supply connector are nested within the enlarged opening space, with the connector positioned to connect to terminals exposed through the opening. This nesting arrangement allows larger connectors to be accommodated within the housing structure.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

A partition wall for partitioning a mirror accommodating space for accommodating a mirror holder and a mirror surface angle adjusting unit, and a harness accommodating space for accommodating a harness are provided in a mirror housing of an electric door mirror. An opening for exposing the terminal part of the mirror surface angle adjusting unit to the harness accommodating space, and insertion through-holes located to surround the opening and through which screws passes from the harness accommodating space toward the mirror surface angle adjusting unit respectively are formed in the partition wall. Further, reinforcing tube portions surrounding the insertion through-holes and protruding to the harness accommodating space are installed in the partition wall.
