Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current disinfecting and sterilizing methods using human labor pose a risk of infection and are inefficient, as they rely on manual spraying and ultraviolet light application, which can expose workers to harmful disinfectants and UV radiation.
Innovation Solution
A mobile device equipped with a spray generating assembly, ultraviolet light-emitting module, scanning module, and controlling module that moves within a working area to perform simultaneous spraying and UV disinfection, automatically stopping operations when a human is detected to prevent exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If human labor is used to perform disinfecting and sterilizing, then the disinfection operation can be conducted, but the risk of infection to workers is increased
Solution Approach 1:
The mobile device performs disinfection operations autonomously without requiring human workers to enter the working area. The device navigates itself, activates spray nozzles and ultraviolet light modules automatically, and returns to charging dock independently, eliminating human exposure to infectious environments while maintaining effective disinfection
Solution Approach 2:
The mobile device serves as an intermediary between the disinfection task and the human environment. It delivers disinfectant spray and ultraviolet radiation to the working area through automated mechanisms, acting as a buffer that prevents direct contact between workers and harmful disinfection agents while ensuring thorough disinfection
2Reliability
If manual spraying and ultraviolet light application are used, then disinfection can be performed, but worker exposure to harmful disinfectants and UV radiation increases
Solution Approach 1:
The mobile device autonomously controls its spray nozzles and ultraviolet light modules based on navigation and environmental sensing. It activates these components only when needed and in appropriate locations, eliminating the need for human operators to handle disinfectants or be exposed to UV radiation while maintaining effective disinfection coverage
Solution Approach 2:
The patent replaces manual mechanical operations with automated systems. The mobile device uses electronic control circuits to activate spray nozzles and ultraviolet light modules, replacing human hands and bodies that would otherwise directly handle these harmful agents. This substitution eliminates worker exposure while preserving disinfection functionality
3Object-affected harmful factors
If automated mobile device is used for disinfection, then worker safety is improved, but device complexity increases
Solution Approach 1:
The mobile device integrates multiple functions into a single platform: navigation, spray disinfection, ultraviolet irradiation, and autonomous charging. By combining these functions in one device rather than separate systems, the patent manages complexity while achieving comprehensive automated disinfection and worker protection
Solution Approach 2:
The patent merges the spray generating assembly and ultraviolet light-emitting module onto a single mobile platform with integrated control. This consolidation reduces the number of separate systems needed, manages complexity through unified design, while maintaining all necessary functions for safe automated disinfection
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 mobile device effectively reduces the risk of infection and enhances disinfection performance by integrating chemical and physical disinfection methods, ensuring safer and more comprehensive disinfection of environments without the need for human labor.
Implementation Method 1
The spray generating assembly, disposed on an external exposed surface of the mobile platform, is used for generating a disinfecting and sterilizing spray for performing the spraying, disinfecting and sterilizing operation
Implementation Method 2
The ultraviolet light-emitting module, disposed at the mobile platform, is used for generating at least one ultraviolet beam to radiate a ground surface of the working area

AI summary
A mobile device includes a mobile platform, a spray generating assembly, an ultraviolet light-emitting module, a scanning module and a controlling module. The spray generating assembly is to generate a disinfecting and sterilizing spray for a spraying, disinfecting and sterilizing operation in the working area. The ultraviolet light-emitting module is configured to generate ultraviolet beams for performing a radiating, disinfecting and sterilizing operation onto a ground surface of the working area. The scanning module defined with an entire scan range is configured to generate a warning signal upon a human in the entire scan range. The controlling module, electrically connected with the scanning module and the spray generating assembly, is configured to control the spray generating assembly to stop generating the disinfecting and sterilizing sprays upon receiving the warning signal, so as to prevent the human from inhaling excessive sprays.
