Problem Areas

7. w w w . d e s m a n i a . c o m
Look and feel of the machine is bland, cold, non premium
compared to other machines.
Most machine from
biotech have the same
base body and different
functions. Differentiating
them while use becomes
difficult.

8. w w w . d e s m a n i a . c o m
Wire management in and around the machine is very poor.
Gives a complicated and untidy feeling to the patient.

9. w w w . d e s m a n i a . c o m
The applicator handle does not have a
strong grip. It is uncomfortable to hold it.

10. w w w . d e s m a n i a . c o m
The flat surface on the machine give space for
people to stack/store things on the machine.

11. w w w . d e s m a n i a . c o m
The screen angle is almost 90 degrees.
Also the screen size is very small.
Thus readability is poor.

12. w w w . d e s m a n i a . c o m
The connector pins are difficult to remove as it is at an
angle facing downwards. Due to this the connecter
end get damaged very frequently. The machine needs
to be lifted every time the wire has to be plugged in.

13. w w w . d e s m a n i a . c o m
There is no storage for the gel bottle, tissues and electrode
pad. This makes the area around the machine very untidy.

14. w w w . d e s m a n i a . c o m
Machine should be comfortable to use with both hands.

15. w w w . d e s m a n i a . c o m
The machine should be stable while in use.
(pressing buttons). It should not wobble or topple over.

16. w w w . d e s m a n i a . c o m
Machine should have a smart software and
an easy interface to assist the doctors.
