Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional rear view mirror systems with integrated cameras suffer from complexity in design and assembly due to varying camera sizes, misalignment issues caused by vehicle vibrations, and increased manufacturing costs for different sized camera housings.

Innovation Solution

A camera assembly arrangement featuring alignment elements, such as stiff ribs and spring elements, outrigger sliders, and adjustable protrusions, which stabilize the camera module on the rear view cover, allowing for different sized cameras to fit securely and resist vibrations, while reducing manufacturing complexity and costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If cameras of different sizes are mounted in the rear view mirror, then the driver's view is enhanced and blind spots are eliminated, but the design complexity and assembly complexity increase

Engineering Contradiction:

Improvedriver's view coverageVSAvoiddesign and assembly complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent employs a universal camera housing design that can accommodate cameras of different sizes through adjustable internal mounting structures. The housing includes standardized mounting interfaces and adjustable support elements that allow various camera models to be installed without requiring different housing designs, thus enhancing view coverage while maintaining design simplicity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The camera assembly is divided into modular components including the housing, mounting bracket, and adjustable support elements. This segmentation allows for standardized interfaces that simplify assembly while accommodating different camera sizes. The modular design enables easy installation and replacement of cameras without affecting the overall mirror assembly.

Inventive Principle:

Principle #1Segmentation

2Reliability

If cameras are mounted on the rear view mirror, then blind spots are eliminated, but vibration effects cause misalignment of the camera

Engineering Contradiction:

Improveview coverageVSAvoidcamera alignment

Core Design Contradiction:

ReliabilityVSManufacturing precision

Solution Approach 1:

The patent incorporates vibration-damping materials and shock-absorbing mounting structures in the camera housing and mounting bracket. These elements are designed to compensate for vibrations before they cause misalignment, maintaining stable camera positioning. The mounting system includes elastic elements and dampers that absorb road vibrations and prevent them from transmitting to the camera module.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The mounting system allows for adjustment of camera position and angle through threaded fasteners and adjustable brackets. This enables precise alignment during installation and provides the capability to recalibrate the camera position if minor shifts occur due to vibrations, maintaining optimal viewing angles throughout the vehicle's operation.

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If different sized camera housings are manufactured, then different camera sizes can be accommodated, but manufacturing costs increase

Engineering Contradiction:

Improvecamera size compatibilityVSAvoidmanufacturing cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The housing design incorporates adjustable parameters such as internal support bracket positions and mounting hole locations that can be configured for different camera sizes. This allows a single housing design to adapt to various camera dimensions, eliminating the need to manufacture multiple housing sizes and reducing manufacturing costs through standardization.
