Removable Visor Lighting Module for Vehicle Interior Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle interior lights are inadequate for locating objects in dark environments, such as when changing a tire or checking oil levels, as they do not provide a portable or directed light source.
Innovation Solution
A visor assembly with a diffused light source and a removable, independently operable directional light source, powered by a rechargeable battery that can be charged by the vehicle, allowing for directed illumination both near and remote from the visor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a portable light source is integrated into the visor, then illumination availability is improved, but device complexity increases
Solution Approach 1:
The lighting system is divided into two independent modules: a diffused light source integrated into the visor for general illumination, and a removable directional light source for focused tasks. This segmentation allows each module to be optimized independently while reducing overall system complexity through modularity.
Solution Approach 2:
The directional light source serves multiple functions: it can be attached to the visor for focused illumination during tasks like checking oil levels, removed and carried separately as a portable flashlight, or stored in the receptacle when not in use. This multi-functionality improves illumination availability across different scenarios without proportionally increasing complexity.
2Illumination intensity
If a removable directional light source is added, then task-specific illumination is improved, but ease of operation deteriorates
Solution Approach 1:
The directional light source is designed to nest within a receptacle on the visor when not in use. The housing of the directional light source contains recesses that receive corresponding protrusions from the visor receptacle, creating a compact nested configuration that simplifies storage and reduces clutter, thereby improving ease of operation.
Solution Approach 2:
The directional light source automatically recharges when docked in the receptacle on the visor, eliminating the need for manual charging operations. The electrical connection is established automatically through engagement with the receptacle, making the system self-servicing and improving ease of operation.
3Use of energy by moving object
If a rechargeable battery system is implemented, then energy independence is improved, but loss of energy increases
Solution Approach 1:
The rechargeable battery in the directional light source is automatically recharged whenever the light source is docked in the receptacle on the visor. This continuous charging process ensures the battery remains full without user intervention, maintaining energy independence while minimizing energy loss through automatic top-up during normal vehicle operation.
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
Provides a portable and effective lighting solution for various tasks within the vehicle, enhancing visibility and usability in dark conditions by combining a diffused light source for immediate use and a directional light source for targeted illumination.
Implementation Method 1
The second light source may be powered by a rechargeable battery that is recharged by the vehicle when the housing is attached to the vehicle
Implementation Method 2
A first light source is disposed in the housing for illuminating an area in front of the mirror. A second light source is disposed in the housing for providing illumination in remote locations
Data Source
AI summary
A visor assembly including a visor, a mirror attached to the visor a diffused light source, and a directional light source. The diffused light source and directional light sources are disposed in a modular housing that is removable from the mirror assembly. The diffused light source is powered by the vehicle electrical system. The directional light source is independently operable and powered by a separate rechargeable battery.
