Solution Overview

Problem

Current showerheads are difficult to disassemble and clean, making it challenging to prevent the growth of legionella bacteria, which can lead to Legionnaires' disease. This results in costly and wasteful practices of replacing entire showerheads instead of just cleaning and replacing parts.

Innovation Solution

A modular showerhead design that allows for easy disassembly, cleaning, and reassembly. The showerhead features a decorative cover that secures all components, enabling users to unscrew and remove interior parts for cleaning without tools, and then reassemble them easily.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If showerheads are designed with integrated components for durability, then reliability is improved, but ease of cleaning deteriorates

Engineering Contradiction:
Improveshowerhead durabilityVSAvoidcleaning accessibility
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The showerhead is divided into multiple separable components including a decorative cover, spray face, and internal mechanisms. This segmentation allows each component to be independently removed and cleaned, resolving the contradiction between integrated durability and cleaning accessibility by enabling disassembly when needed while maintaining structural integrity during use

Inventive Principle:
Principle #1Segmentation

2Reliability

If facilities replace entire showerheads instead of cleaning parts, then reliability is maintained, but loss of substance increases

Engineering Contradiction:
Improveshowerhead functionalityVSAvoidmaterial waste
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

Instead of discarding entire showerheads, the design enables selective removal and cleaning of specific components like the spray face and internal mechanisms. The modular structure allows facilities to recover and reuse the majority of the showerhead assembly, discarding only the soiled components after thorough cleaning, thereby significantly reducing material waste while maintaining functionality

Inventive Principle:
Principle #34Discarding and recovering

3Ease of operation

If showerheads require disassembly for cleaning, then ease of cleaning is improved, but device complexity increases

Engineering Contradiction:
Improvecleaning convenienceVSAvoidassembly structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The showerhead employs a segmented modular design where components are connected through simple threaded interfaces. This segmentation improves cleaning convenience by allowing easy disassembly, while the standardized connection methods prevent excessive complexity by using straightforward mechanical joining rather than complex fastening systems

Inventive Principle:
Principle #1Segmentation

4Ease of operation

If decorative covers are made removable for cleaning access, then ease of cleaning is improved, but reliability deteriorates

Engineering Contradiction:
Improvecomponent accessibilityVSAvoidseal integrity
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The decorative cover is designed as a removable segment that interfaces with the main body through threaded connections. This segmentation allows easy removal for cleaning access while the threaded interface with integrated sealing elements maintains reliability by ensuring watertight reconnection after cleaning, preventing both leakage and bacterial ingress

Inventive Principle:
Principle #1Segmentation

AI summary

The present invention is directed to a modular showerhead that has two different embodiments: a wall mounted showerhead and a handheld showerhead. The present invention is designed to aid in the prevention of water borne illnesses. To achieve this goal, the modular showerhead can be easily disassembled, cleaned, and reassembled. Another feature of the present invention is that it will allow facilities to minimize inventory, save money, and lower their waste output. Current shower heads are not designed to be easily taken apart and cleaned and consequently, hotels frequently discard them instead of cleaning the individual components.
