Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing running board assemblies with built-in lighting are unsightly and limited in functionality, lacking sophisticated lighting options for multiple uses.
Innovation Solution
A retractable running board assembly with end caps featuring optics, where two light sources inside the board emit light towards the optics based on vehicle mode signals, controlled by a controller and user-input device, allowing for various lighting modes and directional illumination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If built-in lighting is added to running board assembly, then illumination functionality is improved, but aesthetic appearance deteriorates (unsightly)
Solution Approach 1:
An optic element is introduced as an intermediary between the light source and the external environment. The optic directs and shapes the light output while being integrated into the end cap, allowing the light source to be hidden from view while still providing illumination functionality. This mediator enables both aesthetic appearance and lighting performance to coexist.
2Adaptability or versatility
If multiple light sources and control systems are added, then lighting versatility is improved, but device complexity increases
Solution Approach 1:
The lighting system is designed with multiple light sources that can operate in different modes (welcome mode, off-road mode, etc.), allowing a single system to perform multiple functions. The controller manages these different operational modes, enabling the running board assembly to adapt to various vehicle uses without requiring separate lighting systems for each function.
3Shape
If light sources are positioned inside the running board, then aesthetic appearance is improved (hidden sources), but manufacturing precision requirements increase
Solution Approach 1:
The optic serves as a mediator that compensates for positioning variations. By directing light from the hidden light source through the optic, the system achieves consistent light output patterns even with variations in light source placement during manufacturing, reducing the stringency of positioning precision requirements.
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 solution provides a functional and aesthetically enhanced lighting system that adapts to different vehicle modes, offering improved illumination and versatility while resisting abrasion and environmental degradation, reducing manufacturing costs.
Implementation Method 1
Two light sources are disposed inside the running board and are each located proximate a corresponding end cap. Each light source is operable to emit light toward the optic of the corresponding end cap
Data Source
AI summary
A running board assembly of a vehicle is provided herein and includes a running board having two ends, each covered by an end cap having an optic. Two light sources are disposed inside the running board and are each located proximate a corresponding end cap.
