Study on Mixer Grinder’s User Behaviour – A Survey-based Analysis

. This work presents the results of a study conducted on the user behaviour of a kitchen appliance (mixer grinder) covering a limited customer base, especially in South India. The user behaviour was evaluated using various parameters. In addition, a hard copy of the questionnaires was prepared, distributed, and collected by co-workers in person. This helped us to reach a wide range of customers. The collected hardcopy data were digitalized using Google docs and was analyzed and plotted using MS Excel., The brand performance was compared. Also, information about the likings, preferences, recommendations, satisfaction of the customers are all analyzed with the help of attainment graphs. The results and information we derived from the present study are explained in detail in this paper.


1.INTRODUCTION
Home appliances play a vital role in our day-to-day life.Appliances are the most important thing in kitchen used for cooking.The study of user behaviour of kitchen appliances is crucial in the modern market as it starts and ends with customers.As a result, all companies are focusing on their customers' satisfaction.Each business should strive to improve its product's performance in order to attract more customers.But the customer's perception and opinion may vary according to various factors like aesthetics, quality, affordability, etc. [1].A mixer grinder is one of the main kitchen appliances found in most households.The mixer grinder's main component is the jar, which comes in a variety of capacities.The mixer jar is used for cutting and grinding the ingredients, which will add more taste to the food.The design of the mixer jar is the main criterion for a good quality grinding.The R&D plants, therefore, mainly focusing on the design area in order to improve the quality of the product and their aesthetic values [2].
The major issue for the customer is the noise and vibration generated during grinding.The noise produced during grinding cannot be tolerable by most of the customers.This is likely to irritate customers; therefore, it needs to be considered during design.In order to avoid this, the base material of the jar can be made of damping sheet, which generates less vibration, thus generating less noise [3].Mixer grinders are selected based on a customer's choice, which is influenced by multiple factors, such as aesthetic value, affordability, quality of grinding, etc.This study mainly deals with the customer's behaviour analysis towards the product [4].

Here, SRM is the low expensive and its unique view of electric machine.6 pole stator and 4 pole rotor and phase windings are used and it's another named as Variable Reluctance Motor.Here rotors do not have any windings and its produced torque.It's one kind of advanced motor because here both stator and rotor used, and it's mainly suitable for coal mining equipment to cutters and coal plough [7].When everything rotates round the client then, at that point the investigation of shopper conduct turns into a need.It begins with the purchasing of products.Products can be purchased separately, or in gatherings.This trade is normally between the dealer and the buyer.To comprehend the preferences of the customer, broad shopper research studies are being led.The review uncovered that way of life qualities significantly affect the purchaser purchasing conduct of the bunches.On the other hand, an individual goes with a decision in a utilization climate to characterize or realize his way of life, recognize it through the items or brands picked.way of life determinants of purchaser purchasing conduct towards home machine items [8].
Electronic products are turning into an essential need as opposed to an extravagance.There is a quick development saw by the organizations creating electronic products since last 10 years.The Consumer loyalty towards Preethi items has been made by the scientist in Coimbatore for concentrating on the need of client needs and their fulfilment.The scientific devices applied for the examination of the information gathered like Straightforward Rate investigation and Chi-square tests.In the investigation of test size was 123 respondents were different age bunch having different occupation.In the determination of respondents, advantageous testing technique was utilized.The review is pointed toward estimating consumer loyalty towards Preethi items in Coimbatore.Showcasing begins before creation and go on after deals.Showcasing is the most common way of making clients.The significant property of the item is quality and costs have gotten good appreciation from the respondents [9].

ANALYSIS METHODODLOGY
The questionnaire form used in this study can be seen in figure 1.In addition, the data were digitally collected with Google Forms and then analyzed with a Microsoft Excel sheet, to enable better understanding and interpretation.In general, data such as gender, age, and family size composition are taken into account, as shown in Figure 1 (a-d), it was found that the responses from women as the most with an age group of 20 to 30 years followed by 4 family members.The mixer grinder brand analysis data is represented in figure 2 along with the Bar graphs which are plotted for various brands with respect to the properties such as grinding quality, grinding time, noise level produced during grinding as shown in figure 3, 4, 5, respectively.

DISCUSSION
The data, which are collected from the survey, are further processed to calculate attainment in 5-point scale system.The attainment points for top brands are calculated depending on various factors, such as brand quality, noise generated, grinding quality, as shown in figure 6, 7, 8, and 9 respectively.Setting a target for the survey is one of the main reasons for calculating attainment.The target can be set based on the survey questions and response.This helps us to study about various factors about kitchen appliances like wet grinder, mixer grinder and gas stove.Once the target is achieved then it can be revised as the process of continuous improvement.This process can be further improved by considering different factors and even some new factors can be introduced later.

OBSERVATIONS AND FINDINGS
The survey is conducted by using googles docs, physical questionnaire print outs, analysed using Microsoft XL sheet, complex mathematical calculations are done followed by generation of various types of graphs for further understanding purposes.
Nearly 26% of the existing customers will opt for an exchange offer replacement during festival seasons which is a very good opportunity for the brands to introduce exchange offer for variety of their products, discounts to maintain the pre-existing customers and to gain further new customers by introducing referral programs and brand loyalty points.Sustainable growth doesn't come up with product sales economically, but also depend on the source and extraction of raw materials such as Rare earth metals like neodymium magnets, copper, aluminium, steel can be recycled from the old appliances and can be added to the new products at minor percentages such that quality of the new product is not compromised.
In-order to follow the 3R's Reduce, Reuse and Recycle as per United Nations Sustainable Developments Goals of GOAL 9: Industry, Innovation and Infrastructure, by developing recycling facilities production of rare earth materials and manufacturing costs are significantly reduced followed by generation of indirect labour and acquiring government incentives.
Many customers who use the grinder for the first time need to understand the grinding capacity of the appliance and how to feed the raw materials accordingly, in-order to prevent over loading of the appliances which may short circuit due to very high amount of initial current needed to run the motor, it can cause the motor windings to burn under high temperature, if the rotor gets stuck during the grinding period.in-order to prevent this self-cut-off switches/fuses can be incorporated as an added safety procedure, over load notification light can be setup which works by the principle of strain gauge to warn the customers.
