Vehicle UV Sterilizer with Deployable UVC LED Array
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing UV sterilizers for vehicles pose safety risks and can negatively impact interior design due to their exposed installation, and they often struggle to effectively expand the sterilization area within the vehicle.
Innovation Solution
A UV sterilizer for vehicles that includes a main body with a storage area for a sterilization part, a driving part to deploy the sterilization part, and a controller to manage operations. The sterilization part features UVC LEDs mounted on a mounting guide with inclinations and reflectors to expand the sterilization area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If UV sterilizer is installed in exposed state to sterilize vehicle interior, then sterilization function is improved, but safety risk and negative interior design effects occur
Solution Approach 1:
The UV sterilizer is divided into a main body part mounted in the vehicle and a separate sterilization part that can be deployed and withdrawn. This segmentation allows the sterilization LEDs to be hidden in the main body when not in use, eliminating safety risks and interior design issues, while enabling effective sterilization when deployed.
Solution Approach 2:
The sterilization part is stored within the main body part when not in use, similar to a nested doll structure. This nesting approach allows the UV sterilizer to maintain a compact, safe, and aesthetically pleasing form factor while the vehicle interior, yet still provide comprehensive sterilization coverage when deployed.
2Reliability
If conventional UV sterilizer is installed to disinfect vehicle interior, then basic sterilization is achieved, but sterilization area cannot be effectively expanded
Solution Approach 1:
The sterilization part includes multiple UV LEDs arranged at different positions and orientations, including inclined mounting guides. This multi-dimensional arrangement of light sources expands the sterilization coverage throughout the vehicle interior, addressing blind spots that single-point UV sterilizers cannot reach.
Solution Approach 2:
Different UV LEDs are positioned at specific locations and angles to target different areas of the vehicle interior. This localized optimization ensures comprehensive sterilization coverage across various zones including seats, dashboard, and door panels, rather than relying on a single omnidirectional source.
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 UV sterilizer effectively sterilizes the vehicle interior by selectively switching between storage and operation states, preventing safety issues and maintaining interior design integrity while expanding the sterilization area.
Implementation Method 1
a plurality of ultraviolet-C (UVC) light emitting diodes (LEDs) mounted on a mounting guide
Implementation Method 2
configured to be withdrawn from the storage area to selectively emit ultraviolet rays to a vehicle interior
Implementation Method 3
having a reflector mounted on the UVC LED

AI summary
An ultraviolet (UV) sterilizer for a vehicle includes a main body part mounted in the vehicle. The main body part has a storage area formed therein. A sterilization part is stored in the storage area and can be deployed from the storage area to selectively emit ultraviolet rays to a vehicle interior. A driving part is coupled to the main body part and configured to provide rotational driving force to allow the sterilization part to be selectively withdrawn into and deployed from the storage area. A controller is configured to selectively control operations of the main body part, the sterilization part, and the driving part.
