2. INTRODUCTION
• The Project
• Designing Process
• Analysis
• Conclusions
• Future Work

3. THE PROJECT
• Our aim: Help to elder or people with physical
disabilities

4. Interesting Data
• According to information from the European Union, about 37
million people in Europe have some type of disability. Of
these, close to 1.2 million are Swedes.
• In the other hand, Sweden has one of the oldest populations
of the world, just after Italy, Greece and Japan. 1.5 million
people were aged 65 or over, which is 15.96 % of the
population. In 2010, the estimated proportion of over-65s will
be 18.6 % and in 2030, it is likely to be as high as 22.6 %.

5. Our purpose
• Be innovative
 Door supplemented by a seat to have an easier
access to the shower
 Applicable for standard bathroom

6. Bath Dimensions
• Bath dimensions: 2.7 x 1.9 (m)
• Conventional shower: 1 x 1.2 (m)
• Doors dimensions: 0.9 x 1.9 (m)

7. Designing Process (Our Model)
• Preliminar model: Accessing shower by a 180º
rotary door.
-Fixing seat on a rotary door with access to
shower.
- Accesing shower by a door rotation of 180
degrees on a central axis.

8. Preliminar Model
The biggest
Disadvantage
is the space

9. Our Final Design
• Final model:
- A conventional door that rotates 90 degrees
on side hinges.

16. CONCLUSIONS
• A Shower´s easy-access solution was
designed.
• Applicable to standard bathrooms
• Made of commercial materials.
• Practical solution.

17. FUTURE WORK
• Consider fatigue and the welding calculations
• Consider an automatic mechanism to open-
close the door.
• Comfort of seat (arm rest, etc)
• Fast belt.
• Become reality (Make prototypes)
• Help for 1.2 million people (population over
65 years old) in Sweden
