A portable genital cleaning system

The project was done as a part of Bachelor's coursework for Engineering Design and fabrication course. The aim was to design a solution and develop a working prototype. The problem area could be selected from the healthcare, social or agriculture sector.
Duration : July 2017- April 2018

Domain of work
Menstruation is a natural phenomenon but still, a comprehensive approach towards menstrual sanitation and hygiene is still not adopted
in India. Mainstreaming of menstrual hygiene management into the present sanitation model is prudent.
The aim was to facilitate adequate menstrual hygiene management, a basic right of every woman guided by the three As.
AVAILABILITY

User Research
Location: Jabalpur, Madhya Pradesh
Areas covered: Chandi Tola (Village), Government city hospital, Sadar Market, Railway station, Schools, Washing Depot

Observations
Deep Interviews
Pop-up Interviews
at public toilets and unorganised sectors
Insights
-
Women restricted in homes during periods
-
Girls skip school during periods
-
Common washrooms at school in villages
-
Public washrooms are not clean
-
Women use washrooms at restaurants/hotels in the market place
-
Usage of rags and unhygienic materials instead of pads
-
No proper bins for pad disposal in trains
-
No washroom at workplace
-
Taboo in the village
-
Face difficulty in changing in trains/buses
-
Overuse of pad during work hours
-
Unavailability of pads in rural areas
“The Sulabh here is not clean, I request nurses at the nearby hospital to let me use the washroom.”
Survey
Around 60 women of all age groups and diverse economical and professional background were asked to take a survey. The questionnaire helped quantify the problem and validated the insights

Problems
Needs
Not changing pads
Cleaning area
washing facilities
Space for changing
Infections due to overuse
Water shortage
Absence of hygenic washrooms
“To design an easy to use, low maintenance and portable product which facilitates proper and hygienic cleaning of the genital area where the provision for the same is not adequate”
These ladies have a problem....

Need groups
Ideation




Analogous inspirations like wudu washing, spray cans used by barbers, asthma pumps etc. were used while generating ideas. The ideas were discussed in the team
sessions and to selected ones were grouped and visualized
CONCEPT EVALUATION
Various concepts for each part were ideated and some
were chosen and refined. These concepts are evaluated
against factors important for performance. The concept
selected were merged andthe product was designed in detail.

Embodiment Design
PUGH MATRIX
DIMENSIONING

The data from ‘Indian anthropometric dimensions for Ergonomic Design Practice’ was referred for fixing
the dimensions of the product. Maximum height and minimum height was used to decide the length of
rod in open and close position. The seat size was fixed using maximum female hip breadth.
Detail Design

Seat:
Length of support (extended)=89.9cm
Length of support (compact)= 40cm
Seat width=50cm
Threefold rod with adjustable height
Hinge joint (tight) at base and seat for
adjusting angle
Drain system:
Vacuum zipping
Opening for draining out waste
Water Storage:
Cylindrical tank
Capacity : 2 litres
Standard hand Shower
Hand vaccum pump


Prototype testing

Alpha prototype

Beta prototype
Once the prototype was tested, changes were identified and a beta prototype was fabricated using the selected materials and mechanisms. The drainage system, the water pump was attached to make a working prototype.
The product was fabricated in the manufacturing lab of the
institute. The prototype was a crude version fabricated
to check if it meets the engineering specifications and
for verification of the functionality. The product was used by three users to validate the concept.
