Adjustable Hair Washing Device with Movable Rear Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hair-washing devices are limited in their ability to accommodate users with reduced or no mobility, as they often require users to be in a specific position (sitting or lying down) and lack the functionality to easily empty water from the basin, restricting their versatility and usability across different mobility conditions.
Innovation Solution
A multi-function hair-washing device composed of dismountable die-cut laminar panels with fold lines, allowing it to be adjusted between two positions to accommodate users standing, sitting, or lying down, with a water outlet system and anti-rubbing protection, enabling comfortable hair washing and water collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a hair-washing device is designed for users sitting or lying down, then it can accommodate users with reduced mobility, but it cannot be used for users standing up or in different positions
Solution Approach 1:
The device incorporates a movable rear appendage that can be repositioned relative to the front basin, allowing the device to adapt to different user positions (sitting, standing, lying down) through dynamic structural adjustment rather than fixed design
Solution Approach 2:
The device is designed to perform the same hair-washing function across multiple user positions and mobility conditions, making it universally applicable to various users regardless of their mobility level or preferred position during washing
2Ease of operation
If a hair-washing device is designed for users lying down, then it can serve bedridden patients, but there is no possibility of emptying water from the bowl
Solution Approach 1:
The device is divided into separable components (front basin and rear appendage) with the rear appendage containing a water outlet opening, allowing the water collection and emptying function to be independently designed and operated without compromising the device's adaptability to different positions
3Adaptability or versatility
If a hair-washing device uses fixed structural elements, then it provides stable support, but it cannot be adjusted for different user positions or mobility needs
Solution Approach 1:
The connection between the front basin and rear appendage allows the rear appendage to move relative to the front basin while maintaining secure connection through connecting means, providing both structural stability during use and positional flexibility for different washing scenarios

AI summary
The invention relates to a multifunctional sanitary hair-washing device comprising two parts that can be detachably connected. The parts are formed by blanked laminar templates and comprise undercuts for coming into contact with the neck of the user, forming a front tub (1) and an additional rear element (2). The front tub (1) comprises at least one water outflow opening (3) used for washing the head. The two parts (1, 2) are joined by means of connecting means (6) which allow the movement of the additional rear element (2) over the front tub (1). Furthermore, the additional rear element (2) comprises at least one second undercut (8) on one side for coming into contact with the neck of the user in a second position of the hair-washing device, rendering said device more versatile.
