Solution Overview
Problem
Existing door mirrors face issues with the detachment of the feeding connector portion after connection, leading to operational challenges during the connection process.
Innovation Solution
A door mirror design featuring a mirror holder, mirror surface angle adjusting unit, and mirror housing with a partition wall and opening portion, including a claw portion and guide portion to securely connect and prevent detachment of the feeding connector portion, utilizing an elastic claw mechanism for easy connection and secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the feeding connector portion is connected to the terminal portion through the opening portion, then the connection operation becomes easier, but the connector may detach during operation
Solution Approach 1:
The claw portion is designed to be elastically deformable, allowing it to dynamically adapt during the connection process. When the feeding connector portion is pushed in, the claw portion elastically deforms to accommodate the connector, then elastically recovers to clamp and secure the connector, preventing detachment while maintaining ease of connection
Solution Approach 2:
The claw portion acts as an intermediary element between the opening portion and the feeding connector portion. It provides a mechanical interface that facilitates easy insertion while simultaneously preventing detachment through elastic clamping action
2Reliability
If a rigid clamping structure is used to prevent detachment, then reliability improves, but the clamping force required increases
Solution Approach 1:
The claw portion's elastic properties allow it to provide sufficient clamping force through material deformation rather than rigid structural force. The elastic recovery of the claw portion generates the necessary holding force, reducing the need for high clamping force structures
Solution Approach 2:
The claw portion is designed as a flexible elastic component rather than a rigid structure. This flexibility allows the claw to deform during insertion and then recover to provide secure clamping with reduced force requirements
Applied Scientific Principles
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 design allows for easy and secure connection of the feeding connector portion to the terminal portion, preventing detachment and ensuring reliable operation with reduced clamping force requirements.
Implementation Method 1
a claw portion which is elastically deformed in a direction orthogonal to a direction of pushing the feeding connector portion by the feeding connector portion when the feeding connector portion is pushed to the terminal portion from a side of the first space, and elastically recovered to be opposed to a back face of the feeding connector portion

AI summary
A mirror housing of an electric door mirror is provided with a partition wall for partitioning a mirror accommodating space and a harness accommodating space. The partition wall is provided with an opening portion for exposing a terminal portion of a mirror surface angle adjusting unit to the harness accommodating space. A peripheral edge portion of the opening portion is provided with a claw portion elastically deformed when a connector portion is pushed to the terminal portion and elastically recovered to be opposed to a back face of the connector portion to thereby prevent detachment of the connector portion after connecting the connector portion to the terminal portion. Further, a peripheral edge portion of the opening portion is provided with a guide portion for restricting a movement of the connector portion against an elastic force of the claw portion.
