Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing showerheads lack a detachable handle and diverter control interface that is easy to use for elderly, shorter people, and children, and do not provide sufficient water coverage while adhering to regulatory flow limits, lacking flexibility in water stream characteristics and aesthetic appeal.

Innovation Solution

A showerhead system with a fixed and removable dispensing unit, where the removable unit overlaps the fixed unit, providing additional nozzle apertures and a diverter interface for flexible fluid flow control, integrated with a handle for easy use and enhanced water coverage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed showerhead design is used, then the structure is simple and easy to manufacture, but the water coverage is insufficient and lacks flexibility

Engineering Contradiction:

Improvewater stream characteristics flexibilityVSAvoidshowerhead structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The showerhead is divided into a fixed dispensing unit and a removable dispensing unit that can be detached and reattached. The removable unit includes a handle and additional nozzle apertures that can be positioned to overlap with the fixed unit, allowing users to change water stream characteristics by removing or repositioning the removable portion.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The showerhead transitions from a static fixed design to a dynamic system where the removable dispensing unit can be easily attached or removed. This allows the water delivery system to adapt between different configurations (fixed only, removable only, or both combined) to provide flexibility in water stream characteristics.

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If a removable dispensing unit with handle is added, then ease of operation is improved for elderly, shorter people, and children, but device complexity increases

Engineering Contradiction:

Improveuser accessibilityVSAvoidshowerhead assembly

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A diverter interface is introduced as an intermediary component between the water supply and the dispensing units. This interface includes a diverter valve that can redirect water flow to different dispensing units, providing an additional layer of control and flexibility in the system.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Area of stationary object

If the removable unit overlaps the fixed unit, then water coverage is increased, but manufacturing precision requirements increase

Engineering Contradiction:

Improvespray face areaVSAvoidnozzle aperture alignment

Core Design Contradiction:

Area of stationary objectVSManufacturing precision

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The removable dispensing unit is designed with nozzle apertures that extend beyond the boundaries of the fixed unit when overlapped. This excessive action ensures that the combined spray coverage is greater than the sum of individual units, maximizing water coverage while allowing for some tolerance in alignment during installation.

Inventive Principle:

Principle #16Partial or excessive action

4Adaptability or versatility

If a diverter interface is integrated, then fluid flow control flexibility is improved, but device complexity increases

Engineering Contradiction:

Improvefluid flow controlVSAvoidcontrol mechanism

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The diverter interface serves multiple functions: it can redirect water to the fixed dispensing unit, the removable dispensing unit, or both simultaneously. This multi-functionality is achieved through a single integrated component, reducing the need for multiple separate control mechanisms.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A showerhead with a removable portion is provided that includes a fixed fluid dispensing unit supported at a location. The fixed dispensing unit has a fixed nozzle apertures arranged on a fixed spray face within a first area of between 55 and 95 percent of the fixed spray face, the fixed spray face having a second area devoid of fixed nozzle apertures and contiguous with the first area. A removable fluid dispensing unit has a front face defining a front face area, a back surface in opposition to the front face, and removable nozzle apertures arranged on the front face, the back surface adapted to overlap the second area of the fixed spray face and protrude in every portion from the fixed spray face. A handle and fluid supply house are provided.
