Blind Spot Indicator Lens Assembly for Driver-Focused Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blind spot indicators for motor vehicles face issues with illumination directed away from the driver and high assembly costs, necessitating a solution that efficiently avoids unwanted illumination while reducing costs.
Innovation Solution
A blind spot indicator assembly featuring a printed circuit board (PCB) with a gap for light passage, a lens assembly attached with double-side adhesive tape, and a light control assembly to redirect light, allowing for efficient illumination towards the driver without additional fixations, thus simplifying assembly and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a conventional blind spot indicator assembly is used, then the driver can be warned of objects in blind spots, but illumination is partially directed away from the driver and assembly costs are high
Solution Approach 1:
The housing is divided into a light source assembly and a reflective assembly, allowing independent optimization of each component's function and simplifying manufacturing processes
Solution Approach 2:
A reflective surface is introduced as an intermediary element to redirect light from the light source toward the driver, solving the illumination direction problem without requiring complex optical systems
2Illumination intensity
If additional fixations are used to control light direction, then illumination can be directed towards the driver, but assembly complexity increases
Solution Approach 1:
The light source assembly and reflective assembly are merged into a single integrated housing structure, eliminating the need for additional fixations and simplifying assembly while maintaining controlled light direction
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
