Water Dispenser Float Assembly for Overflow Prevention

Solution Overview

Problem

Existing water dispensers face drawbacks such as overflow issues due to larger top tanks and inefficient water level regulation, leading to suboptimal performance in dispensing filtered water.

Innovation Solution

A water dispenser design featuring an upper chamber for unfiltered water, a multiple-layer filtering assembly, a lower chamber for filtered water, and a float assembly system that regulates water flow based on the lower chamber's water level, preventing overflow and ensuring continuous water supply.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If a larger top tank is used to ensure continuous water supply, then the water supply duration is improved, but overflow issues occur due to inadequate water level regulation

Engineering Contradiction:

Improvewater supply durationVSAvoidoverflow prevention

Core Design Contradiction:

Duration of action of moving objectVSReliability

Solution Approach 1:

The float assembly system provides automatic feedback control by detecting the water level in the bottom tank and相应地 opening or closing the aperture to regulate water flow, preventing overflow while maintaining continuous supply

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The float assembly system automatically regulates water flow without external intervention, opening the aperture when water level is low and closing it when the tank is full, enabling self-service water level control

Inventive Principle:

Principle #25Self-service

2Reliability

If manual water level regulation is used to prevent overflow, then overflow prevention is improved, but device complexity increases and operation efficiency decreases

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 effectively regulates water flow and prevents overflow, ensuring a continuous supply of filtered water while maintaining a larger top reservoir, thus addressing the inefficiencies of prior designs.

Implementation Method 1

a float assembly system operably coupled between the upper and lower chambers, the float assembly system including a float body configured to open and close the aperture in the filter assembly depending on a level of the filtered liquid in the lower chamber

Methodology Applied

Scientific EffectBuoyancy: Archimedes' Principle (Buoyancy)

Implementation Method 2

a multiple-layer filtering assembly operably coupled to the upper chamber and in communication with the aperture for the unfiltered liquid to pass through an aperture in the filter assembly

Methodology Applied

Scientific EffectPhysical filtration: Filter (physical)
