Problem definition to design a machine which is able to complete drawing in 30 seconds who is range of it should not increase more than 3500 Rs and the maximum size of pattern it can draw should be A4 and should work continuously for 20 minutes and it's reliability should be 2 to 3 years the weight of machine should not exceed to 3 kg size of machine should not be more than 1.5 cubic feet
| sl.no. | functions |
|---|---|
| 1 | Two designs per minute |
| 2 | should give indication if stuck in middle |
| 3 | should give indication after work is complete |
| 4 | should be able to draw one pattern at a time |
| 5 |
Problem definition 👍 Design a pattern drawing machine with straws two designs per minute which gives indication is stuck in middle or if the work is complete and should be able to draw one pattern at a time
Final version of Problem definition 👍 Design pattern drawing machine that can draw different shapes and patterns which is in the range of budget of less than 3,500 and it should be able to run both on electricity and battery it should also draw two designs in a minute and it should be made of acrylic sheet material and should work with paper it must be both machine and human control it should draw a single pattern at a time and should be able to use different colour pencils and it should be able to draw the pattern which is of A4 size and should atleast work for 20 minutes without any abruption and its reliability should be minimum of 2 to 3 years and it should be portable and the weight of machine should not exceed more than 3 kg it can be used for personal purposes and their size of machine should not exceed 1.5 cubic feet.
