Solution Overview

Problem

Sanitary hand showers face challenges in accommodating electrical components such as accumulators and generators in a space-saving manner, as existing designs do not efficiently utilize the available space in the hand area for these components.

Innovation Solution

The design splits waterways into partial waterways, creating a free space in the hand area that can be used for additional components like accumulators and turbines, with a removable accumulator unit housed in a trough-like structure, allowing for efficient recharging and integration of flow sensors and circuit boards for controlling electrical devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If waterways are split into partial waterways and components are arranged in edge areas, then usable space for electrical components is created, but device complexity increases

Engineering Contradiction:
Improveusable space for electrical componentsVSAvoidwaterway structure complexity
Core Design Contradiction:
Volume of moving objectVSDevice complexity

Solution Approach 1:

The waterway is segmented into multiple partial waterways that are arranged in the edge areas of the hand area. This segmentation creates a free space in the middle region where electrical components can be accommodated, thus resolving the space constraint while maintaining the water flow function through the distributed partial waterways.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The design transitions from a centralized waterway arrangement to a distributed edge-based arrangement, utilizing the peripheral dimension of the hand area. This dimensional reorganization creates central free space for component accommodation while maintaining water flow through the edge-located partial waterways.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If accumulator is made removable in an integrated unit with window cover, then ease of operation for recharging is improved, but device complexity increases

Engineering Contradiction:
Improveaccumulator removal and rechargingVSAvoidaccumulator unit integration
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The accumulator is merged with the window cover to form an integrated accumulator unit. This combination allows the accumulator to be removed as a single unit through the window opening, simplifying the recharging operation. The merged design eliminates the need for separate removal steps for the cover and accumulator, thus improving ease of operation while the integration is managed through standardized coupling mechanisms.

Inventive Principle:
Principle #5Merging (Combining)

3Extent of automation

If flow sensor and circuit board are integrated in usable space, then automation of electrical control is improved, but device complexity increases

Engineering Contradiction:
Improveelectrical device controlVSAvoidcircuit arrangement complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The usable space in the hand area is designed as a multi-functional zone that accommodates the flow sensor, circuit board, and other electrical components. This universal space serves multiple functions including sensing, control, and power management, thereby achieving automation of electrical device control while containing the complexity within a dedicated modular region.

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

AI summary

The spray (1) has a spray head formed with a discharge nozzle for a water jet. A hand area supports the spray head and has a water path extending from a connection to the spray head. A junction is provided in the water path that is split into two partial water paths at the junction. The partial water paths completely or partially surround a utilization area and are merged in another junction. An accumulator is accommodated in the utilization area. The utilization area is surrounded by a side opened trough.
