Camera Bracket Assembly With Bendable Substrate for Stable Field of View
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible substrates used in vehicle camera bracket assemblies with shape memory characteristics tend to return to their original flat shape, preventing proper field of view acquisition due to the shape memory effect.
Innovation Solution
A bracket assembly design incorporating a flexible substrate with a glare shield substrate and a sidewall substrate, featuring a channel such as a score or perforations to maintain the angled configuration, ensuring the substrate remains attached to the camera bracket.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible substrate with shape memory characteristic is used to attach electrical components on the windshield, then the substrate can be initially positioned, but it returns to its original flat shape and prevents proper acquisition of the camera's field of view
Solution Approach 1:
The flexible substrate is divided into multiple segments or zones with different properties. The first portion (attached to the bracket) has different characteristics than the second portion (extending toward the windshield), allowing each segment to fulfill its specific function while resolving the shape memory conflict
Solution Approach 2:
Different portions of the flexible substrate are given different local qualities or properties. The first portion near the bracket may have different flexibility, thickness, or structural characteristics compared to the second portion, enabling the substrate to maintain both attachment stability and proper field of view geometry
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 effectively maintains the angled configuration of the flexible substrate, allowing the camera to acquire a clear field of view and function properly in systems like lane departure warning and automatic emergency braking.
Implementation Method 1
due to the shape memory characteristic of the flexible substrate, the flexible substrate returns to its original flat shape

AI summary
A bracket assembly includes a camera bracket having a glare shield surface and a sidewall surface. The bracket assembly further includes a flexible substrate having a glare shield substrate configured to be attached on the glare shield surface, a sidewall substrate configured to be attached on the sidewall surface, and a channel between the glare shield substrate and the sidewall substrate. The flexible substrate is folded with an angle between the glare shield substrate and the sidewall substrate.
