1.2 BASIC SURVEY AND REQUIREMENTS

Table 2: Observation from a literature survey

SI.NO	OBSERVATION FROM SURVEYS	REQUIREMENTS
01	Weight of system	It should be easy to carry and handle
02	No of operations	around the clock
03	Cost	Machine should be built with minimum budget
04	Materials to be used	Materials used to build, must be non toxic and light weight

1.3 Identifying Client's Objectives

Table 3: Objectives identified

SI.NO	OBJECTIVES
01	System should be semiautomatic.
02	System should be portable.
03	System should be hygienic
04	System should be User-friendly.

Design a semiautomatic microgreen system, which is a hygienic ,it should be portable and user-friendly

1.4 Identify constraints

Step 1: Prepare a list of design constraints

    Table 4: Identified Constraints

SI.NO	C0NSTRAINTS
01	System should be 2.5 -3.5kg weighted.
02	Dimensions 2ft2ft2ft
03	Cost of the System should be within Rs-4000
04	One type seed can be grown
05	The system should produce the yield in 7days
06	It should be grown without soil

Problem definition version 1.2 :-

Design a semiautomatic microgreen system, system must not exceed the volume of 2ft2ft2ft and 2.5-3.5 kg ofweight .Grown without soil,system should produce yeild in 7 days and budget to build should not exceed Rs. 4000.

1.5 Establish Functions

Step 1: Prepare a list of design functions

      Table 5: Identified Functions

SI.NO	FUNCTIONS
01	Seed dispensing system
02	Source of light
03	should work around the clock
04	should store the seeds

Problem definition version 1.3 :-

Design a semiautomatic microgreen system with the seed dispensing system and storing system it should be grown in source of light and it should be work around the clock
