Object Analysis

Describe the object

A microwave oven is an electric kitchen appliance that uses microwaves to heat foods and drinks. Microwave ovens can be standard, in which case they only serve the purpose of heating food. The microwave can also have a grill or it can be combination microwave oven. The control section of a microwave oven has an electronic or electromechanical timer. This is used to control the power output and different protection devices. The high voltage is converted to microwave energy and this enables it to heat the food.

Describe the need the object addresses

A microwave addresses the need of eating cold foods and drinks. It produces radio waves or microwaves with frequencies of about 2500Mz, which heat the food. The microwaves are absorbed by water, sugars and fats. They are not absorbed by most types of plastics, ceramics and glass and this means that they heat the food directly.

State the goal or the objective of the object

The main objective of a microwave is to reheat food using the least amount of time possible.

Describe the possible users of the object

Microwave ovens can be used by anybody who knows how they work. They are used in homes, offices, hotels and other eating outlets, and schools among other places where people are. Some microwave ovens are small and are used in small kitchens in the homes. Other microwaves are huge and are therefore inbuilt. These microwaves are used in commercial kitchens such as those found in some restaurants. One does not have to be a professional cook or chef so that they can use the microwave because it is relatively easy to use. Children can be easily taught the basic ruled of using a microwave.

Describe the relevant characteristics and capabilities of the object

A microwave can be used for heating food, defrosting, grilling, broiling, baking and cooking. Microwave ovens prevent burning because they have an automatic timer. The oven stops releasing the microwave energy when the timer stops or when the door is opened. They have automatic controls, which are used for easy programming of cooking commands. Some commonly cooked or heated foods and beverages have controlled commands. Microwave ovens are of many varieties, models and sizes. The kitchen size does not have to be a limitation for one to have a microwave.

Describe the materials and resources used to create the object

Some important components of the microwave oven are the transformer, which supplies energy to the magnetron tube. The magnetron tube supplies electromagnetic radiation to the oven and maintains the required temperature. The door is usually made of glass and has a layer of mesh, which prevents electromagnetic radiation. The control panel can have an LED, LCD or vacuum fluorescent display. Most turntables in microwave ovens are made of glass or plastic, though there are a few made of metal. The walls can be made from ceramics or plastic. Other materials such as stainless steel, ceramics, plastics and metals are used for making various parts of the microwave oven.

Evaluate any deficiencies or limitations with the current design of the object

Microwave ovens have several limitations. The first limitation is that it does not use metallic containers because they interfere with the microwaves. Another limitation is that microwave ovens cannot be cleaned using abrasives such as scouring pads. The microwave does not distribute heat equally to the food making some areas cold while others are hot. Another limitation of the microwave oven is its capacity. Most models have a small capacity. One cannot cook different foods at the same time or put larger dishes when heating or cooking food.

Based on your evaluation, state whether the object fulfills its intended need or not and why

A microwave fulfills its intended use. Different models have different capabilities but they retain their use of reheating food within a relatively short time. As the need to develop an appliance that performs more than one task increases, different models, each having new additional features, have been introduced in the market. Most of the modern designs have the capability of browning foods and making them crisps, in addition to grilling and baking. The microwave has managed to fulfill its intended use and it has exceeded the expectations of those who first developed it.

Explain how the object analysis process relate to a systematic approach to designing instruction

The object analysis process provides an easy and systematic way of designing the product’s instructions. It enables the person to have a clear view of the product description, its purpose, advantages, features and limitations. It is a simple way of summarizing the descriptive details of the product without using difficult technological language. This ensures that no important details are left out. It gives one the chance to review the work and check whether there are any details, such as warnings, which he or she did not include. It also gives the person a chance to include newly discovered information, such as issues related to health.
