Solution Overview

Problem

Existing dehumidifiers with large water tanks face challenges in handling and convenience, as the water tank is often too heavy to handle with one hand due to lack of a suitable handle structure, and existing handle designs can lead to water spillage due to tilting.

Innovation Solution

A dehumidifier design featuring a water tank with a handle integrated into the top surface, allowing for easy grasping and movement, and a tank drawer system that allows for vertical withdrawal and tilting without exposing the handle externally, ensuring safe and convenient water disposal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a large-capacity water tank is provided to improve dehumidifying performance, then the water storage capacity increases, but the water tank becomes too heavy to handle with one hand

Engineering Contradiction:
Improvewater storage capacityVSAvoidhandling convenience
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The water tank assembly is divided into two functional parts: a fixed mounting structure attached to the dehumidifier body and a detachable water tank that can be removed. This segmentation allows the water tank to be separated from the heavy dehumidifier unit, making it easier to handle and empty even when containing large amounts of water.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A tank drawer is introduced as an intermediary component between the dehumidifier body and the water tank. The tank drawer provides a sliding mechanism that facilitates easy removal and reattachment of the water tank, reducing the effort required to handle the water tank assembly.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If a handle structure is added to facilitate water tank removal, then handling convenience improves, but the handle exposes externally and deteriorates the outer appearance

Engineering Contradiction:
Improvewater tank removal convenienceVSAvoidouter appearance
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The handle is nested within the water tank structure rather than being an external attachment. The handle is positioned inside the water tank assembly, allowing it to be hidden when the water tank is mounted on the dehumidifier, thus maintaining a clean external appearance while remaining accessible when the water tank is removed.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The handle structure is designed to be dynamically positioned - inside the water tank during normal operation and easily accessible when the water tank is removed. This dynamic arrangement allows the handle to serve its function without permanently affecting the aesthetic appearance of the dehumidifier.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If the handle is disposed to lean forward for easy grasping, then ease of operation improves, but the water tank tilts during lifting and spills water

Engineering Contradiction:
Improvegrasping convenienceVSAvoidwater spillage prevention
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The handle is positioned to naturally guide the user's hand in a grasping motion before lifting begins. This preliminary positioning ensures that the user's grip is established in a way that maintains proper water tank orientation from the start of the lifting action, preventing tilting and spillage.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The handle is positioned at a height and angle that creates a balanced lifting posture, making the water tank assembly easier to lift without requiring the user to tilt or twist the tank. This equipotential positioning distributes the weight more evenly and maintains stable orientation during the lifting process.

Inventive Principle:
Principle #12Equipotentiality

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

Enables easy handling and disposal of the water tank with a large capacity using one hand, preventing water spillage and maintaining a clean, unobstructed exterior appearance.

Implementation Method 1

a dehumidifier may absorb heat from surrounding air by evaporating a liquid refrigerant in the evaporator

Methodology Applied
Scientific EffectEvaporation: Evaporation

Implementation Method 2

moisture contained in the air may be condensed to form dew on a surface of the evaporator

Methodology Applied
Scientific EffectCondensation: Condensation

AI summary

A dehumidifier and a water tank for a dehumidifier are provided. A withdrawable handle is provided on the water tank, which collects condensed water, and thus, when the water tank is mounted, the water tank is mounted in a state in which the handle is inserted, and when the water tank is withdrawn or moved, the handle is withdrawn, improving convenience in use.
