Our faculty guide ROHIT KAMBLE has explained as all about design engineering and also helped us in our project a lot.
1.1. Design Engineering
Design Engineering is a general term that covers multiple engineering disciplines including electrical, mechanical, chemical engineer, aeronautical engineer, civil, Computer Engineering, Information Technology and structural/building/architectural engineers. The uniting concept is a focus on applying the 'engineering design process, in which engineers develop new products or processes with a primary emphasis on functional utility.
While industrial designers may be responsible for the conceptual aesthetic and ergonomic aspects of a design, the design engineer usually works with a team of engineers and other designers to develop conceptual and detailed designs. He may work with industrial designers and marketers to develop the product concept and specifications, and may direct the design effort.
1.2. Thinking Procedure:
o Find our goal
o Evaluation of goal

3. Mind Mapping Canvas
The image of Mind Mapping canvas is given below
Fig. (2). Mind Mapping Canvas
4. Empathy Canvas
Understanding the problem of society is one of the biggest challenges for engineering student as till now they were making project on imaginary ideas. So the day 1 session was based on understanding the domains of the problem in broader sense which emphasized on interacting with the people of your domain area which included more of casual talk rather than technical session. And this is the empathy canvas.
Here we would like to explain the aspects of this canvas by our project which is modification of Solar Grass Cutter
4.1 Users:
o Farmers
o Institutes
o Restaurants
o Household Peoples
4.2 Activities:
o Grass Cutting
o Spraying Pesticides
o Ground Cleaning
o Shaping Grass
4.3 Stakeholders:
o Engineer
o Manufacturer
o Marketing
o Businessmen
The image of Empathy Mapping Canvas is given below
Fig. (3). Empathy Mapping Canvas
5. Ideation canvas
• After some days we have started working with people where we simply thought about the people for whom we want to solve the problem. We started with our ideation canvas.
• For our product we have listed the people who can generally use our product. All general people like shopkeeper, developers, students, farmer, etc are people who will use our product.
• The thought for context/location /situation and finally for possible solutions.

CONCLUSION:
Our project entitled Fabrication of solar powered grass cutter is successfully completed and the results obtained are satisfactory. It will be easier for the people who are going to take the project for the further modifications. This project is more suitable for a common man as it is having much more advantages i.e, no fuel cost, no pollution and no fuel residue, less wear and tear because of less number of moving components and this can be operated by using solar energy. This will give much more physical exercise to the people and can be easily handled. As we are nearer to Equator, the solar energy (non-conventional energy) is vastly available, so it is easy to charge the battery and is also pollution free. But the initial investments of
the solar powered grass cutter is high. At present in order to curtail global warming and ozone depletion, the Government of India is offering subsidy for the solar equipments. The industries are producing these components in mass productions, so the cost of the system may come down. So in future it is expected to run all equipments by using solar energy. This system is having facility of charging the batteries while the solar powered grass cutter is in motion. So it is much
more suitable for grass cutting also. The same thing can be operated in night time also, as there is a facility to charge these batteries in day light.
