Diaper Changing Table with UV Self-Cleaning and Foam Cushion Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current diaper changing tables are uncomfortable for infants due to hard plastic surfaces, lack convenient accessory storage, and fail to self-clean effectively, leading to pathogen growth.
Innovation Solution
The design incorporates a foamed cushion for comfort, multifunctional hooks and loops for accessory storage, and a UV light system with a timer for self-cleaning, ensuring a safe and hygienic environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a hard plastic surface is used for the changing table, then the structure is simple and easy to manufacture, but the comfort for infants deteriorates
Solution Approach 1:
The changing table combines hard plastic structural components with a soft foam cushion layer. The foam cushion is attached to the hard plastic surface, creating a composite structure that maintains structural integrity while providing infant comfort. This resolves the contradiction by integrating both hard and soft materials in a single functional surface.
2Device complexity
If no hook or loop mechanism is provided, then the device complexity is reduced, but the convenience for accessory storage deteriorates
Solution Approach 1:
The handle of the changing table is designed to serve multiple functions: it acts as a structural component for moving the table, a carrying handle for transport, and an integrated hook/loop mechanism for hanging accessories like diapers and wipes. This multi-functional design provides accessory storage convenience without adding separate dedicated components, thus maintaining relatively simple device complexity.
3Device complexity
If the changing table surface is not self-cleaning, then the device complexity is low, but pathogen growth occurs after repeated use
Solution Approach 1:
The changing table incorporates a UV-C light system that automatically activates to disinfect the foam cushion surface after each use. The system includes a sensor that detects when the table is not in use and triggers the UV-C lights to cycle on and off, providing self-cleaning functionality. This allows the table to maintain hygiene automatically without requiring manual intervention, resolving the contradiction between simplicity and pathogen prevention.
4Ease of operation
If a soft foam cushion is added for comfort, then the comfort for infants is improved, but the ease of cleaning deteriorates
Solution Approach 1:
The UV-C self-disinfection system automatically cleans the foam cushion surface by exposing it to germicidal ultraviolet light. This eliminates the need for manual cleaning interventions and allows the soft foam material to be used without compromising hygiene maintenance. The system cycles the UV-C lights on and off based on sensor detection, providing continuous self-cleaning capability.

AI summary
A changing table includes a wall assembly and a tray assembly. The wall assembly includes a transparent panel, a reflector, and a UV light source disposed in between. The tray assembly is pivotally attached to the wall assembly, forming a changeable angle α in between. The tray assembly includes a front panel and a cushion layer. The cushion layer forms a concaved surface that receives an infant. The concaved surface receives UV light generated by the UV light source.
