Solution Overview

Problem

Existing hydromassage devices are bulky, expensive, and lack manual adjustment capabilities, with rotatable nozzles requiring manual rotation for direction change and unable to vary water flow strength or arrest flow without external components, and are not compact enough for narrow installations.

Innovation Solution

A hydromassage device with a rotatable nozzle driven by a motor, allowing for directional and strength control of water flow, with the nozzle capable of rotating 360 degrees or partially, and integrated with a compact motor design for smaller dimensions, enabling separate control of each nozzle and pulsating massage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a rotatable nozzle is used to change water flow direction, then the massage coverage is improved, but the device requires manual rotation which increases operation complexity and time

Engineering Contradiction:

Improvemassage coverageVSAvoidoperation complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent replaces manual mechanical rotation of the nozzle with an electric motor-driven rotation system. The motor automatically rotates the nozzle to change water flow direction, eliminating the need for manual operation and reducing operation complexity while maintaining improved massage coverage.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces dynamic control of the nozzle rotation through motor drive, allowing the nozzle to change direction automatically based on control signals. This dynamic system enables the nozzle to adapt its orientation without manual intervention, improving ease of operation while maintaining versatility.

Inventive Principle:

Principle #15Dynamics

2Extent of automation

If a motor is added to rotate the nozzle and control water flow, then the automation is improved, but the device size and complexity increase

Engineering Contradiction:

ImproveautomationVSAvoiddevice complexity

Core Design Contradiction:

Extent of automationVSDevice complexity

Solution Approach 1:

The patent merges the motor, nozzle, and housing into an integrated assembly where the motor is positioned directly within or adjacent to the nozzle structure. This merging reduces the number of separate components and minimizes overall device complexity while maintaining high automation capability for nozzle rotation and water flow control.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent nests the motor within the housing structure or positions it in close proximity to the nozzle, utilizing the existing device volume efficiently. This nesting approach allows the motor to be incorporated without significantly increasing the external dimensions or overall complexity of the hydromassage device.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Adaptability or versatility

If the device is made compact for narrow installations, then the adaptability to different locations is improved, but the space for accommodating motor and components is reduced

Engineering Contradiction:

Improveadaptability to locationsVSAvoiddevice volume

Core Design Contradiction:

Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The patent applies local quality optimization by positioning the motor and critical components in specific locations within the compact housing where space is most efficiently utilized. The motor is placed in close proximity to the nozzle, and the housing is designed with optimized internal geometry to accommodate these components without increasing the overall external dimensions, thereby maintaining adaptability to narrow installations.
