Solution Overview

Problem

Conventional water purifiers suffer from water splashing issues due to the fixed height of the water discharge port, which can lead to inefficiency and waste, especially when using glasses of varying sizes, and the movable water discharge nozzle tends to randomly descend due to its self-weight, making it difficult to maintain a desired height.

Innovation Solution

The water purifier incorporates a movable water discharge module with a resistance unit and guide part to adjust the nozzle's height, preventing splashing and ensuring the nozzle remains at the desired position, featuring a stainless steel nozzle and a tray that rotates for improved user convenience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a fixed water discharge port is used, then the structure is simple and stable, but water splashing occurs due to height difference with the water glass

Engineering Contradiction:
Improvewater dispensing effectivenessVSAvoidwater splashing
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The water discharge nozzle is made movable along the vertical direction, allowing it to dynamically adjust its position according to the height of the water glass. This dynamic adjustment eliminates water splashing by ensuring the water discharge port aligns with the glass opening, while maintaining structural simplicity through a guide groove mechanism rather than complex actuators.

Inventive Principle:
Principle #15Dynamics

2Object-affected harmful factors

If a movable water discharge nozzle is used to adjust height, then water splashing is prevented, but the nozzle randomly descends due to self-weight

Engineering Contradiction:
Improvewater splashingVSAvoidnozzle position stability
Core Design Contradiction:
Object-affected harmful factorsVSStability of the object's composition

Solution Approach 1:

The movable case is equipped with a stopper that automatically engages with the guide groove to maintain the water discharge nozzle at a predetermined height. This self-service mechanism prevents random descent due to self-weight without requiring external power sources or complex control systems, achieving stable position maintenance through simple mechanical means.

Inventive Principle:
Principle #25Self-service

3Stability of the object's composition

If the water discharge nozzle is fixed, then position stability is maintained, but it cannot adapt to different glass heights

Engineering Contradiction:
Improvenozzle position stabilityVSAvoidcompatibility with different glass sizes
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The water discharge nozzle is made movable along the vertical direction, allowing it to dynamically adjust its position according to the height of the water glass. This dynamic adjustment enables compatibility with different glass sizes while maintaining stability through the guide groove and stopper mechanism that prevents random movement.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The water discharge module is divided into a movable case containing the nozzle and a fixed case with the guide groove. This segmentation allows the nozzle portion to move independently for height adjustment while the overall module remains structurally stable, achieving both adaptability and stability simultaneously.

Inventive Principle:
Principle #1Segmentation

4Adaptability or versatility

If a movable water discharge module is used, then height adjustment is enabled, but operational complexity increases

Engineering Contradiction:
Improveheight adjustabilityVSAvoiddischarge module structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The water discharge nozzle is made movable along the vertical direction, allowing it to dynamically adjust its position according to the height of the water glass. This dynamic adjustment enables compatibility with different glass sizes while maintaining stability through the guide groove and stopper mechanism that prevents random movement.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The movable case is equipped with a stopper that automatically engages with the guide groove to maintain the water discharge nozzle at a predetermined height. This self-service mechanism prevents random descent due to self-weight without requiring external power sources or complex control systems, achieving stable position maintenance through simple mechanical means.
