Solution Overview

Problem

Existing rear-view mirror systems for motor vehicles are undesirably complex and costly, necessitating an improved design that addresses these issues.

Innovation Solution

A folding actuator cover assembly is introduced, comprising a first cover component with a receiving portion for a driving mechanism and a second cover component for attaching a mirror pane, where the first plane is angled relative to the second plane, allowing for a compact and integrated design.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If traditional separate cover components are used for actuator and mirror pane, then manufacturing and assembly are simpler, but device complexity and cost increase

Engineering Contradiction:
Improvestructure complexityVSAvoidmanufacturing complexity
Core Design Contradiction:
Device complexityVSEase of manufacture

Solution Approach 1:

The patent merges the first cover component (for actuator) and second cover component (for mirror pane) into a single integrated cover assembly. The first cover component includes an upper actuator cover and a bottom actuator cover that are rotatable together with respect to the vehicle body portion, eliminating the need for separate cover components and reducing overall structural complexity while maintaining manufacturing feasibility.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The first cover component serves multiple functions: it protects the actuator mechanism, provides a rotatable mounting structure for the mirror assembly, and integrates with the second cover component to form a unified protective enclosure. This multi-functionality reduces the total number of parts needed in the system.

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

2Weight of moving object

If compact integrated design is implemented, then weight and aerodynamics improve, but manufacturing precision requirements increase

Engineering Contradiction:
Improvemirror system weightVSAvoidangular alignment precision
Core Design Contradiction:
Weight of moving objectVSManufacturing precision

Solution Approach 1:

The patent implements a nested structure where the bottom actuator cover is positioned within the upper actuator cover, and the second cover component is integrated with the first cover component. This nesting arrangement achieves compact integration and weight reduction while the layered structure provides tolerance accumulation that reduces the impact on manufacturing precision requirements.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Device complexity

If fewer parts are used, then cost and complexity reduce, but reliability may worsen due to integration

Engineering Contradiction:
Improvenumber of partsVSAvoidsystem reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent incorporates preliminary action features in the form of receiving portions that are pre-configured in the first and second cover components. These receiving portions are designed to automatically guide and position the driving mechanisms during assembly, ensuring proper alignment and reducing the risk of assembly errors that could compromise reliability. The receiving portions act as built-in alignment features that prevent misalignment issues.

Inventive Principle:
Principle #10Preliminary action
