Revised Problem Definition:

"Design a chocolate wrapping for wrapping chocolate which should be best at sensing and dispensing,hygieniC. The machine should be semi-automatic and size should be restricted to 222 feet.Machine should weigh around 2 kgs , with more durability. The cost of the machine should not exceed Rs.4000."

Functions:

• The Chocolate Wrapping Machine runs with source of electricity power.
• The chocolate should be wrapped according to the algorithm given to it.
• The machine is type of semi-automatic.
• It should sense the input and dispense out according to shape of chocolate.
• And the machine should always accept paper first and later chocolate.
• Machine wrappes chocolate more safely with manually kept labelled paper.
• Machine should be able to select the shape of chocolate according to input given to it.
• Reliably ensure product hygiene by eliminating hand contact with chocolates

Problem Definition v1.3:

Design a semi-automatic Chocolate Wrapping Machine which is able to wrap the chocolate properly,hold it firmly and is User-friendly. The size should be approximately of 2x2x2 feet. Moreover the machine should be portable according to the needs of owner with high output. The machine should be able to identify the chocolate size and even cut the paper required for it to wrap chocolate in more efficient manner. It should be running with electricity. Machine should approximately wrap 100 chocolates per hour.
