Rotatable Directional UV Projection Head for Surface Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional UV disinfection devices require multiple arms for surface disinfection, increasing manufacturing time and costs, and often result in inefficient surface coverage and energy wastage due to limited directional projection.
Innovation Solution
A mobile UV projection device with a rotatable projection head that projects UV light across a path, rotating about a horizontal axis to cover surfaces above and lateral to the device, allowing for efficient disinfection without multiple arms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple arms with UV lamps are used for surface disinfection, then surface coverage is improved, but device complexity and manufacturing costs increase
Solution Approach 1:
The patent employs a rotatable projection head that can dynamically change its orientation to cover different surface areas. Instead of using multiple static arms, a single projection head rotates to disinfect surfaces on both sides of the device, thereby achieving wide coverage while maintaining simple device structure.
Solution Approach 2:
The single projection head serves multiple functions by rotating to different positions. It can disinfect surfaces on the left side, right side, and potentially multiple angles, replacing what would traditionally require multiple separate arms or projection heads.
2Adaptability or versatility
If multiple arms with separate moving assemblies are used, then surface disinfection capability is improved, but manufacturing time and costs increase
Solution Approach 1:
The patent merges the functionality of multiple arms with separate moving assemblies into a single projection head with rotation capability. This consolidation reduces the number of components that need to be manufactured and assembled, thereby reducing manufacturing time and costs while maintaining versatile surface disinfection capability.
3Use of energy by moving object
If UV light is projected in a single direction, then energy efficiency is improved, but surface coverage per unit time is limited
Solution Approach 1:
The projection head performs periodic rotation to cover different surface areas. By alternating between different orientations in a systematic manner, the device maintains energy efficiency (projecting UV light in one direction at a time) while achieving comprehensive surface coverage over time through the periodic change in projection direction.
4Area of stationary object
If arms are extended linearly or rotatably to deploy UV lamps, then surface coverage is improved, but operational time and area downtime increase
Solution Approach 1:
The rotatable projection head provides dynamic surface coverage without requiring time-consuming extension or deployment mechanisms. The head can quickly rotate to different positions to cover various surfaces, eliminating the need for linear extension or complex rotatable arms that会增加 operational time and downtime.

AI summary
Embodiments of the present disclosure provide an apparatus and a method for projecting UV light towards surfaces across a path. The apparatus includes a mobile body and including opposing lateral sides and a sagittal plane passing between them. The apparatus also includes a projection head rotatably mounted to the mobile body. The projection head operates to project UV light directionally towards surfaces located above and proximate to the opposing lateral sides, where the projection head is adapted to rotate about a horizontal axis in the sagittal plane while the UV light is being projected towards the surfaces.
