Solution Overview

Problem

Existing water outlet devices are inconvenient for users as they require manual adjustment of the ball to change the water outlet direction, making it difficult to rinse the mouth or wash the face effectively.

Innovation Solution

A water outlet device with two water ports forming a 90° angle in the water channel, featuring a first and second ball rotatably connected to the water supply and outlet components, allowing for flexible adjustment of the water outlet direction, including upward and downward discharge.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the ball is rotatably connected to change water outlet direction, then the water outlet direction can be adjusted, but users have to manually receive water which is extremely inconvenient

Engineering Contradiction:
Improvewater outlet direction adjustmentVSAvoidconvenience of water reception
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The ball rod is designed to be dynamically adjustable with two balls that can rotate independently, allowing the water outlet direction to change from horizontal to upward discharge. This dynamic structure enables the faucet to adapt to different usage scenarios (drinking vs. face washing) without manual intervention for water reception

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention adds a vertical dimension to the water outlet by enabling upward water discharge through the 90-degree angled water ports. This dimensional change allows water to be discharged upward for direct drinking without requiring users to manually receive water from a horizontal outlet

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of manufacture

If the angle between two water ports is not 90 degrees, then the structure may be simpler, but water splashing occurs during upward or downward discharge

Engineering Contradiction:
Improvestructural simplicityVSAvoidwater splashing
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The invention specifies a precise 90-degree angle between the two water ports in the ball rod. This parameter optimization ensures that when water flows through the vertically oriented port after rotation, it discharges upward without splashing. The 90-degree angle creates optimal flow alignment that prevents harmful splashing while maintaining manufacturing feasibility

Inventive Principle:
Principle #35Parameter changes

3Device complexity

If only one ball is used in the ball rod, then the device complexity is reduced, but the water outlet direction cannot be adjusted to upward position

Engineering Contradiction:
Improvenumber of balls in ball rodVSAvoidwater outlet direction range
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The ball rod is segmented into two independent rotational joints with two balls positioned at different locations. The first ball controls rotation in one plane while the second ball controls rotation in another plane, creating a segmented control system that achieves comprehensive directional adjustment capability including upward discharge position

Inventive Principle:
Principle #1Segmentation

AI summary

A water outlet device includes a ball component. The ball component comprises a ball rod and a ball. Two water ports and a water channel located between the two water ports are sequentially formed in the ball rod. An angle is formed between the directions of the two water ports. The ball is arranged on at least one water port. The water channel penetrates through the ball. The two water ports having an angle formed between water flow directions thereof are formed in the water channel of the bail rod, so that the water outlet direction of the water outlet device can be adjusted to be upward, and the water outlet angle can be adjusted to some extent.
