Head Support Device with Nested Swing Mechanism for Easy Cleaning
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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
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.
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.

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.
