Solution Overview

Problem

Existing portable child sinks require plumbing hook-ups, making them inconvenient and costly, and limiting their flexibility and mobility, especially in locations without access to plumbing.

Innovation Solution

A portable child sink design featuring a base with a built-in fresh water tank, a motion-activated faucet and soap dispenser, and a waste water container system that allows for easy setup and relocation, eliminating the need for plumbing connections and using a clip attachment system for secure and easy detachment of components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If plumbing hook-ups are required for child sinks, then water supply and drainage functions are achieved, but flexibility in placement and mobility are decreased

Engineering Contradiction:

Improvewater supply functionVSAvoidplacement flexibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The sink system is divided into separate modular components: a base unit with integrated fresh water reservoir and waste water container, and removable vessel inserts. This segmentation allows the sink to function independently without plumbing while maintaining water supply and drainage capabilities through built-in storage containers.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The plumbing infrastructure is extracted and replaced with self-contained water storage and waste collection systems. The fresh water tank and waste water container are integrated into the base, eliminating the need for external plumbing hook-ups while preserving the essential water supply and drainage functions.

Inventive Principle:

Principle #2Taking out (Extraction)

2Reliability

If plumbing hook-ups are required for child sinks, then water supply and drainage functions are achieved, but installation cost and complexity increase

Engineering Contradiction:

Improvewater supply functionVSAvoidinstallation simplicity

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The sink system is designed to be self-sufficient with integrated fresh water and waste water containers that handle all water supply and drainage needs independently. Users simply fill the fresh water tank and empty the waste water container, eliminating the need for professional plumbing installation while maintaining full water management functionality.

Inventive Principle:

Principle #25Self-service

3Reliability

If fixed plumbing connections are used, then stable water supply is ensured, but mobility and ease of relocation are reduced

Engineering Contradiction:

Improvewater supply stabilityVSAvoidmobility

Core Design Contradiction:

ReliabilityVSWeight of moving object

Solution Approach 1:

The sink system transitions from a fixed plumbing connection to a dynamic, movable design with integrated water containers. The base unit with fresh water and waste water tanks can be easily relocated throughout the home while maintaining stable water supply functionality through its self-contained reservoir system.

Inventive Principle:

Principle #15Dynamics

AI summary

An apparatus includes a base; a reservoir connected to the base and configured to hold a fluid; a first vessel having a first volume and configured to be removably connected to the base; a connection configured to deliver the fluid from the reservoir to at least the first vessel; and a second vessel. The second vessel is configured to be disposed at least partially within the first vessel; configured to be removably secured to the first vessel; includes an aperture that allows for fluid communication between the second vessel and the first vessel; and has a second volume that is less than the first volume.
