Solution Overview

Problem

Current shower devices with long pipelines between the showerhead and control box result in water waste, poor user experience, and material wastage due to the need for exposed or buried pipelines.

Innovation Solution

A showerhead with a built-in water passage control apparatus, including a temperature regulating valve and changeover switch, allows for direct connection to cold and hot water sources, eliminating the need for long pipelines by enabling hot water output without residual cold water and reducing material waste.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a long pipeline is used between the control box and showerhead, then the showerhead can be positioned at a distance from the water sources, but water waste occurs due to residual cold water in the pipeline

Engineering Contradiction:
Improveshowerhead positioning flexibilityVSAvoidwater waste
Core Design Contradiction:
Ease of operationVSLoss of substance

Solution Approach 1:

The patent merges the control box and showerhead into a single integrated unit, eliminating the long pipeline connection between them. The control components (thermostatic controller or mixing valve) are housed within the showerhead body itself, allowing direct connection to water sources and eliminating water waste from residual cold water in long pipelines.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If a long pipeline is used between the control box and showerhead, then the showerhead can be positioned at a distance from the water sources, but material waste and maintenance issues arise from exposed or buried pipelines

Engineering Contradiction:
Improveshowerhead positioning flexibilityVSAvoidpipeline installation complexity
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The control box and showerhead are combined into one integrated device, eliminating the need for separate pipelines connecting them. This integration removes the complexity of pipeline installation, whether exposed or buried, and eliminates material waste from unnecessary piping.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If the control box is positioned far from the showerhead, then installation flexibility is improved, but the section for remaining cold water increases

Engineering Contradiction:
Improveinstallation flexibilityVSAvoidtime to discharge cold water
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

By integrating the control box within the showerhead, the patent eliminates the distance between water supply and discharge point. The thermostatic controller or mixing valve is positioned inside the showerhead body, ensuring that heated water is produced and delivered immediately without requiring discharge of cold water from long pipelines.

Inventive Principle:
Principle #5Merging (Combining)

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 reduces water waste, improves user experience, and eliminates the need for external or buried pipelines, saving materials and simplifying maintenance.

Implementation Method 1

the temperature regulating valve is provided with an adjusting switch which is configured to be capable of adjusting the opening degree of the temperature regulating valve to adjust the mixing ratio of cold and hot water entering from the water inlet end
