Solution Overview

Problem

Current bathing devices, such as showerheads and bathtubs, lack convenience and versatility in controlling water flow and distribution for filling bathtubs to specific levels and applying multiple functions like showering and personal hygiene simultaneously.

Innovation Solution

The development of showerheads with integrated cylindrical rotary valves and float mechanisms that allow for adjustable water flow control, enabling the device to function as both a conventional showerhead and a bathtub filler, along with additional features like electronic sensors for precise water level detection and integration with oral care and fluid dispensers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a showerhead is used to fill a bathtub, then water can be supplied to the bathtub, but it is difficult to control the water level and shut off the flow automatically

Engineering Contradiction:
Improveconvenience of filling bathtubVSAvoidcomplexity of water level control
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system uses electronic sensors to automatically detect water level and control valve operation without requiring manual intervention. The controller autonomously shuts off water flow when the desired level is reached, allowing the system to serve itself in monitoring and controlling the filling process.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Electronic sensors continuously monitor the water level in the bathtub and provide feedback signals to the controller. Based on this feedback, the controller adjusts the control valve to maintain the desired water level, creating a closed-loop control system that automatically responds to changing conditions.

Inventive Principle:
Principle #23Feedback

2Adaptability or versatility

If multiple bathing functions are integrated into one system, then versatility is improved, but device complexity increases

Engineering Contradiction:
Improveversatility of bathing functionsVSAvoidcomplexity of integrated system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system is designed to perform multiple bathing functions including showering, bathtub filling, and personal hygiene tasks through a single integrated platform. The control valve and electronic control system can switch between different出水 modes and functions, allowing one device to replace multiple separate bathing devices.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The integrated system is divided into modular components including the showerhead assembly, electronic sensors, control valve, and fluid dispensers. This segmentation allows each component to be optimized for its specific function while working together as a coordinated system, managing complexity through functional decomposition.

Inventive Principle:
Principle #1Segmentation

3Measurement precision

If electronic sensors and control valves are added to the showerhead, then water level control precision is improved, but manufacturing complexity increases

Engineering Contradiction:
Improveprecision of water level detectionVSAvoidease of manufacturing showerhead
Core Design Contradiction:
Measurement precisionVSEase of manufacture

Solution Approach 1:

Traditional mechanical water level control mechanisms are replaced with electronic sensors and electronically-controlled valves. This substitution enables more precise measurement and control capabilities while allowing for programmable logic to handle complex control decisions, though it does increase manufacturing complexity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
