Solution Overview

Problem

Existing mounting arrangements for driver assist systems on vehicle windshields lack a secure and efficient method to ensure unobstructed camera views while minimizing the impact of extraneous light and providing stable attachment.

Innovation Solution

A mounting bracket with keyhole slots and mounting posts that align and lock securely to the windshield, allowing for a symmetrical and stable installation of the driver assist system housing, ensuring an unobstructed camera view and reducing light interference through a camera viewing window and light traps.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a mounting bracket is used to secure the driver assist system housing to the windshield, then the stability and reliability of the mounting is improved, but the complexity of the mounting arrangement increases

Engineering Contradiction:
Improvemounting stabilityVSAvoidmounting arrangement complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The mounting bracket is divided into multiple functional components: a mounting plate with keyhole slots for positioning, mounting posts with locking mechanisms for secure attachment, and alignment features for precise installation. This segmentation allows each component to perform its specific function efficiently while maintaining overall system reliability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mounting bracket acts as an intermediary element between the driver assist system housing and the windshield. It provides a stable connection interface that simplifies the mounting process while ensuring reliable attachment, thereby resolving the contradiction between mounting stability and arrangement complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If keyhole slots and mounting posts are used for alignment and locking, then the ease of installation is improved, but the device complexity increases

Engineering Contradiction:
Improveease of installationVSAvoidmounting bracket complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The keyhole slots are pre-formed in the mounting plate with specific geometries that guide the mounting posts into proper alignment during installation. The locking features are pre-configured on the mounting posts, allowing for quick and easy engagement without requiring complex adjustment procedures during installation.

Inventive Principle:
Principle #10Preliminary action

3Object-affected harmful factors

If a camera viewing window is provided in the mounting bracket, then the camera view unobstructedness is improved, but the structural integrity of the bracket may be compromised

Engineering Contradiction:
Improvecamera view obstructionVSAvoidbracket structural integrity
Core Design Contradiction:
Object-affected harmful factorsVSStrength

Solution Approach 1:

The mounting bracket is designed with a camera viewing window at the specific location where the camera requires an unobstructed view. The keyhole slots and mounting posts are positioned in areas that do not interfere with the camera field of view, allowing the bracket to maintain both structural integrity and optical accessibility where needed.

Inventive Principle:
Principle #3Local quality

AI summary

A mounting arrangement for securing a housing to a windshield of the vehicle includes a mounting bracket having a plurality of keyhole slots, each having a receiving opening at one end of the keyhole slot, a locking recess at another end of the keyhole slot, and a ramp connecting the receiving opening with the locking recess. A plurality of mounting posts each including a base portion, a head portion, and a collar portion are mounted to the windshield and positioned to align with associated keyhole slots in the mounting bracket. The keyhole slots and the mounting posts are arranged such that the head portion of each mounting post is received into the receiving opening of its associate keyhole slot, slidable up the ramp of its associated keyhole slot, and lockable into the locking recess of its associated keyhole slot. The housing is attachable to the mounting bracket.
