CHAPTER II REVIEW OF RELATED LITERATURE AND STUDIES.
This chapter presents and shows the literature and studies to the present under taking study. It also includes the synthesis of the art, gap bridge by the study, the theoretical and conceptual frameworks of the study. Technical terms likewise have been conceptually and operationally defined for a better understanding of the text.
RELATED LITERATURE
Fales et. Al., pionted out that the continuous progress in technology, including innovations, has profoundly affected our lives in many ways. It has also affected even the construction industry.1 Because of the advancement of technologies; more work can be done faster, easier, and better. The study relates to fales’ view, which focuses on the development of technologies, the same way as the present study came up with a new functional device that will be developed from an existing model.
Everyone is potentially creative, in fact, today’s advancement of technology are all products of man’s creativety. According to Lowenfield et. Al., the development of creative thinking has tremendous importace for us, both as individual and as a society. It offers a change from what is and has been, to what might be or what is to be discovered and developed.2 In like manner, the present study highly involoved critical creative thinking, every aspect undergo extensive study.
Agpaoa made mention of the home made rewinding stand that can be use in rewinding. It is manually operated transformer rewinder. To record the number of turns, a counter can be attached at the rewinding shaft where the bobbin can be mounted. If no counter is available, one can record the number of turns.3 The idea brougth about by the said model of a traditional rewinder was applied by the researchers in this study as a reference in constructing the prototype. The device has similar function and some parts can be found in the said model.
In the past years, man has developed many techniques for harnessing elctricity and putting it to use. All industrial societies have been drastically transformed by the ability to generate electric power and transmit it over long distance. Electrid power runs elictric motors in
fabrics and provides ligths in homes and cities.4 In like manner; the device was supplied with electric power in order for it to operate.
Rotating electrical machines are commonly used for converting energy from one form to another. One of the most frequently used types of such machines is the motor that converts electrical energy into mechanical energy. According to Siskind, when an electric motor is in operation, it is supplied with electric energy and develops torque. And if the rotating element of the motor is free to turn, it will do so and thereby cause mechanical rotation of it self and its application.5
Today, electric motors are widely used in many applications such as funs, pumps, portable drills, advertising devices, and sewing machines that is why the progress of motor technology over the past several decades can not be understimated. This advancement was made possible through a combination of improved design, materials and manufacturing process. It even provides longer service life in much more several environments than any of its predecessor design. Jordan pointed out that the relatively inexpensive energy conversion from electrical to mechanical form provided by electric motor has enjoying today.6
Smith cited that one of the major problems of the magnitude in the school of developing countries is the scarcity of equipment, both in terms of machines and hand tools. In most class, these can not be purchased however it is possible to design and build simple tools and devices, which can be used to increase production to aid home industries and improve the shop program.7 Accordingly, this study aimed to develop a device that can be used in school shop as a material for instruction and demonstration, which improved the industrial program. This would provide students experiences and training to develop their skills so that later they would become highly competent and skilled manpower, who would led to the increase of production.
RELATED STUDIES
Serrano et.al study focused on Electrically operated Grater an innovative study, a motor is used to operate the grater. The electric motor drive’s the grater that ensures safe and fast preparation of food. The device is intended customarily to eliminated difficulties in grating Cassava and other hard root crops. The present study is similar to the previous study since they both used electric motor was used in the prototype to ensure safe and fast rewinding.
The study of
Polo and Guarte,”pedal operated slicer”, the
efficiency of their machine is being demonstrated to slice cassava into uniform sizes and thickness the innovative design of this mechanical slicer makes food processing a lot easier and less time consuming. With the machines large capacity of 50 kg/hr it is not only ideal for classroom use but also for large scale production. For the present study, the device is not only intended for classroom instruction but also for industries to be used by technician.
The study of Musa et.al,”Portable Transfomer rewinder (A Utility Model)”, focused on the design and constracting of transformer rewinder with an motor to speed up the rewinding process. The device helps reduce the time in rewinding and becomes portable for the user. This study is similar to the present since they both used a motor on their prototype.
The Sensing device of Montas could be installed in electric water pump to protect its motor from any serious damage that may araise from a low suction pressured. It has been proven that the device is an efficient instructional device particularly in demonstrating the functional relationship between the various parts of electric pumps. This study is similar to the present since the device was developed as a tool for effective instruction specially in the proper way of rewinding motor.
The study of Navera “A three-phase circuit demonstrations board for quality teaching” provides an innovative device that can be used to improve the performance skill of the students in the field of electrical technology. Likewise, in this present study, it also aimed to improve the performance skill of the students particularly in motor rewinding.
The study of Barquilla and Batiancila, “Motor Controlled Transformer Rewinder”, focuse on the design and construction of transformer rewinder with an speed controller to speed up rewinding process. This study is similar to the present in terms of its function, however the present study tried to use a motor on the device for more precise and convenient job.
Another developmental study of Moron et. Al, “An Electronic Lighting Arrester for Appliances: a developmental study”, had proven that protects all appliances automatically and sensitively. The finding shows that the device has the qualifying quality, which can enhance the assurance of the fortification of the appliances. The researchers of the present study assure that the device has the quality to protect the windings from any damage of failures.
SYNTHESIS OF THE ART
All the related studies reviewed are found similar to the presents study in terms of input and throughput that involved planning and designing, tools and equipment, and in terms of the process which involve constructing and testing. The difference was in the output of the study. There were studies that have similarities with the present study in purpose that is to serve as a model, instructional device and skill development. The design and construction of the device as well as the safety precaution were also emphasized. In the study of Navera and Montas are similar to the present study that is to provide efficient instructional materials and to improve the performance skill of the students. The study of Musa et. Al., and Serrano et. Al,. and Barquilla and Batiancila use electric motor in their study same as with the present study to speed up the work being done. The study of Moron, and Polo and Guarte assure safety and precaution as well as conserving time and energy. The present study is similar in terms of the method used, the developmental method as well as the designing and construction of the device.
GAP BRIDGE BY THE SUDY
Generally, the previous studies reviewed have led the present study in developing, improving the functions, and features of the existing model. A similar device used in electrical technology is the “motor controlled transformer rewinder” of Barquilla and Batiancila, which has using an electric motor with 3-speed controller motor. Using this transformer rewinder you can adjust the speed of the motor if needed while doing the winding. The present study tried to develop a “JIG AND FIXTURE FOR MOTOR REWINDING” using a motor and a gear with a constant speed of 60 rounds per revolution. This was the gap the researchers tried to bridge.
THEORETICAL FRAMEWORK
The study was anchored on the use of several theories as basis of the development of “Jig and Fixture for Motor and Rewinding,” The theory of creativity according to Wallace involve the imagination and formation not yet visible in order to develop a certain device, it must first be based on the imagination and creativity of man, on how to formulate certain develop using the mind, which is very important function in the
development of the devices. Also according to Lester G.Telser’s” theory of innovation, he stated that competition in the modern economy is not the impersonal kind popular in may textbook, there is instead keen rivalry among firms to kind better products and cheaper ways of waking them. The winner of this contest may obtain large profits and this stimulates the research,”It is said in the theory of innovation that making make a research make better than the existing one. This is what the researchers have though of, that is to construct the Jig and Fixture for Motor Rewinding, to surpass the function of the already existing Motor Rewinder.
The statements said above are our basis to make this device “Jig and fixture for motor Rewinding.” the innovations, invention and creativity of this device used for massive production of highly needed by man, while the Technology is continuously improving the faster the people seek for it. One of the purposes of this device is to lessen up the work of people.
