Solution Overview

Problem

Conventional rearview devices often have aesthetic and functional issues due to the presence of a bezel that wraps around the electro-optic element, which can obstruct the view and create an unsightly appearance.

Innovation Solution

A rearview device housing design that incorporates a peripheral flange and lip structure, allowing the electro-optic element to be positioned within a recessed area without a bezel, enhancing visibility and aesthetic appeal by maintaining a sleek, compact curvature.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a bezel wraps around the electro-optic element, then the electro-optic element is supported and positioned, but the view is obstructed and the appearance becomes unsightly

Engineering Contradiction:
Improvesupport and positioning of electro-optic elementVSAvoidview obstruction and unsightly appearance
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent removes the traditional bezel structure that wraps around the electro-optic element. Instead, the electro-optic element is positioned within a recessed area formed by the peripheral flange and lip structure, eliminating the harmful visual obstruction while maintaining proper support and positioning through the integrated housing design

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The housing structure merges the support and positioning functions previously provided by a separate bezel into the main housing body. The peripheral flange and lip structure integrate the electro-optic element mounting directly into the housing, eliminating the need for a distinct bezel component

Inventive Principle:
Principle #5Merging (Combining)

2Strength

If a bezel is used to support the electro-optic element, then structural support is provided, but the device complexity increases and aesthetic appeal decreases

Engineering Contradiction:
Improvestructural support for electro-optic elementVSAvoidnumber of components and structural elements
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The housing structure merges the support and positioning functions previously provided by a separate bezel into the main housing body. The peripheral flange and lip structure integrate the electro-optic element mounting directly into the housing, eliminating the need for a distinct bezel component and reducing overall device complexity

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The peripheral flange structure serves multiple functions simultaneously: it provides structural support, defines the recessed positioning area, and maintains the sleek external appearance. This multi-functional design eliminates the need for separate support components

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

AI summary

A rearview device having a housing that defines a cavity. The rearview device additionally includes an electro-optic element. In some embodiments, the housing may comprise a peripheral flange. The peripheral flange may have a mounting surface and a lip. The electro-optic element may be associated with the mounting surface. Further, the lip may substantially circumscribe the electro-optic element. In other embodiments, the rearview device may further comprise a mounting assembly having one or more mechanical fastener acceptors. One or more mechanical fasteners may be received by the mechanical fastener acceptors and extend through holes both in a holder and a circuit board disposed in the cavity. In yet other embodiments, the one or more mechanical fasteners may be received by the mechanical fastener acceptors and extend through and be supported by a washer disposed in the cavity.
