Solution Overview

Problem

Conventional shower systems use high water volumes to produce continuous streams of water, failing to simulate the experience of rain, which some users prefer for its sound and feel.

Innovation Solution

A shower assembly that uses a panel with inlet ports and reservoirs to form discrete drops of water, mimicking rain, by controlling the flow and temperature of water through a control system, and optionally including a streaming apparatus to provide both drops and streams.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If conventional shower systems use high water volume to produce continuous streams, then the shower experience is satisfied, but water consumption increases

Engineering Contradiction:
Improvewater volumeVSAvoidshower experience quality
Core Design Contradiction:
Quantity of substanceVSProductivity

Solution Approach 1:

The patent segments the water flow into discrete droplets of varying sizes (small, medium, large) that fall at different rates, mimicking natural rain patterns. This segmentation allows the system to create a satisfying shower experience using much less water than continuous streams, directly resolving the contradiction between water consumption and shower quality

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system employs periodic action by controlling droplets to fall in rhythmic patterns with varying intervals, creating a natural rain-like experience. This periodic droplet delivery provides sensory satisfaction similar to continuous flow while using significantly lower water volumes

Inventive Principle:
Principle #19Periodic action

2Stability of the object's composition

If conventional shower systems produce continuous streams, then water flow is consistent, but the rain-like feel and sound are not simulated

Engineering Contradiction:
Improvewater flow consistencyVSAvoidrain simulation capability
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent applies local quality by creating different droplet sizes (small, medium, large) with different fall rates from the same shower system. This allows simultaneous provision of consistent water delivery and varied rain-like sensations, enabling the system to maintain flow stability while achieving rain simulation versatility

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system transitions from static continuous flow to dynamic droplet patterns where droplets of varying sizes fall at different rates. This dynamic approach allows the system to adapt between consistent water delivery and rain-like simulation, resolving the contradiction between flow stability and rain simulation capability

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If shower systems use multiple flow channels for different water patterns, then versatility increases, but device complexity increases

Engineering Contradiction:
Improvewater pattern varietyVSAvoidflow channel configuration
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges multiple flow channel functions into a single integrated system where one showerhead produces all droplet sizes and patterns simultaneously. This consolidation achieves versatile water patterns (rain, stream, mist) without the complexity of multiple separate flow channels, resolving the contradiction between versatility and device complexity

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A shower assembly (100) is provided. The shower assembly (100) has a panel (102) including a wall (110) and a first plurality of holes (108) passing through the wall from the inner surface to the outer surface, each hole (108) of the first plurality of holes comprising an inlet and an outlet. The wall (110) at least partially defines a reservoir (120) and has an outer surface on a side of the wall toward a showering area and an inner surface on a side of the wall (110) away from the showering area. When water is provided to the reservoir (120), water passes through the first plurality of holes (108), forms a drop (20) at the outlet of each of the first plurality of holes (108), and falls from the panel (102) as a plurality of drops (20).
