Solution Overview

Problem

Existing head support devices in shampoo bowls pose interference with treatment and are difficult to clean due to exposed parts and rotation shafts.

Innovation Solution

A head support device with a base attached to the shampoo bowl edge, featuring a swing device with a first contact member for the head and a second contact member for the neck, using a connection structure that includes support projections and rails, allowing for inward and outward swinging motion without increasing lateral size.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If rotation shafts and suspended members are used to enable flexible head support movement, then the head support can follow client position, but the exposed parts interfere with practitioner treatment and are difficult to clean

Engineering Contradiction:
Improveflexibility to follow client positionVSAvoidease of cleaning
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent embeds the rotation shafts and mechanical components inside the head support structure itself, rather than having them externally suspended. The head support base contains internal rotation mechanisms that allow the contact members to swing and adjust to client position while keeping all moving parts enclosed, eliminating exposure to water and chemicals and removing interference with practitioner access.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Adaptability or versatility

If exposed rotation shafts and suspended members are used for head support movement, then flexible positioning is achieved, but treatment access is interfered with

Engineering Contradiction:
Improveflexible positioning capabilityVSAvoidinterference with treatment
Core Design Contradiction:
Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The rotation shafts and mechanical components are nested within the head support base structure. The contact members extend from the enclosed mechanism to contact the client's head and neck, allowing flexible positioning while the enclosed design prevents interference with practitioner treatment access.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The head support employs a shell-like enclosed structure that contains all mechanical components. This flexible enclosing design allows the contact members to move and adapt to client position while the shell itself provides a smooth, non-interfering surface that does not obstruct practitioner access to the client's head and neck area.

Inventive Principle:
Principle #30Flexible shells and thin films

AI summary

The present disclosure provides a head support device that does not pose interference with treatment and is easy to clean. A head support device 8 includes a base 17 and a swing device 24 connected to the base 17 using a connection structure 32. The swing device 24 includes rails 26, first contact members 27 to come into contact with a client's head, bar-like or plate-like support projections 28 projecting upward, and a second contact member 29 attached to the support projections 28. The first contact members 27 swing together with the swing device 24 in the front-back direction about first swing fulcrums 45. The second contact member 29 swings in the front-back direction about second swing fulcrums 46 that are the upper end portions of the support projections 28.
