Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing UV light-based laundry sanitization methods pose risks of eye damage and lack clear indicators for adequate UV exposure, making them less user-friendly and effective, especially in dynamic laundry environments.
Innovation Solution
A UV light assembly with a mobile unit and base unit that uses sensors and an activation module to control UV light exposure, ensuring power is only supplied when specific criteria are met, and includes UV-sensitive laundry sheets for monitoring exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If UV light is used to sanitize laundry, then disinfection effectiveness is improved, but risk of eye damage increases
Solution Approach 1:
The patent introduces an opaque housing as an intermediary barrier between the UV light source and the user's eyes. The housing completely encloses the UV lights, allowing the disinfection function to operate while physically blocking harmful UV radiation from reaching users during normal operation.
2Reliability
If UV light exposure time is extended to ensure adequate sanitization, then disinfection effectiveness is improved, but difficulty in determining adequate exposure increases
Solution Approach 1:
The patent employs UV-sensitive laundry sheets that undergo color changes when exposed to UV light. These sheets are placed among the laundry during drying, and their color transformation provides a simple visual indicator that adequate UV exposure has occurred, eliminating the need for complex monitoring systems.
3Ease of operation
If UV light device is made portable in laundry ball form, then ease of operation is improved, but risk of unauthorized use by children increases
Solution Approach 1:
The patent divides the UV treatment system into two separate components: a mobile unit containing the UV lights and a stationary base unit with activation controls. This segmentation ensures that the harmful UV source cannot be activated without adult supervision at the base unit, while still maintaining ease of use through the simple mobile component.
Solution Approach 2:
The stationary base unit acts as an intermediary control mechanism between the user and the mobile UV unit. It requires deliberate adult action to activate the UV lights, preventing accidental or unauthorized activation by children while the mobile unit itself remains safe to handle.
4Object-affected harmful factors
If activation controls are added to prevent unauthorized use, then safety is improved, but device complexity increases
Solution Approach 1:
By separating activation controls into a distinct stationary base unit, the patent adds safety functionality without complicating the mobile UV unit. The control system complexity is isolated to the base unit, which remains in a fixed location and does not require portability.
Solution Approach 2:
The system uses automatic sensor-based activation at the base unit that detects when the mobile unit is placed in the correct position and when laundry is present. This self-service activation reduces the need for complex manual controls while maintaining safety through automated monitoring of operational conditions.
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 safe and controlled UV light exposure to laundry, ensuring effective sanitization while preventing accidental exposure and allowing users to gauge the adequacy of UV treatment.
Implementation Method 1
one or more UV lights carried by the housing and directed exteriorly therefrom
Implementation Method 2
A UV light-sensitive laundry sheet can be used to gage UV light exposure to the laundry
Data Source
AI summary
An apparatus for exposing laundry to ultraviolet (UV) light comprises a mobile unit having a housing and at least one UV light carried by the housing and directed exteriorly therefrom. An activation module is located in the housing and configured to supply electrical power to the at least one UV light only when at least one activation criterion is satisfied. A battery power unit located in the housing supplies the electrical power to the at least one UV light via the activation module. The mobile unit can be connected to a base unit located on an interior surface of a laundry machine door. A UV light-sensitive laundry sheet can be used to gage UV light exposure to the laundry.
