Product Design and Prototype Making – Lab Report Example

LAB REPORT by + Aim of the report The main aim of the report was to come up with question list following the inquiry from the client. The report also aims at improving the interpretation of the needs of customers and taking the necessary actions. Additionally, the paper also helps to gain the relevant experience to come up a preliminary product specification (Chou and Hsiao, 2005).
2. Objective of the Report
ABC Limited is one of the leading companies in manufacturing company. Based on the company’s inquiry, the report will provide some of the electronic timer quotations. The electronic timer will be used to control the chemical processes in the company. To perform this, the more information was gathered from the client and recorded directly to the logbook.
3. Question List
What are the necessary components needed to design, implement, and a test a timer?
Why are the listed products and components important in in the design, implementation, and testing?
What are the specific functions of the components needed for the above named components?
What are the appropriate measures needed for the design, implementation, and testing?
What are the effects of input frequency?
What are the limitation of voltage?
4. The interpretation of the raw data
When R1 was connected the Vb total was found to be 20mV while the Vb for the alternating current was found to be 40mV. The main function of R1 was to reduce the Direct Current which was placed at the bottom of the transistor. When C1 was disconnected the Vb total came to 24mV while the Alternating current for Vb was recorded at 50mV. The main purpose of the C1 was to add the Direct Current component into the transistor’s bases. In situations when the C1 was absent, the 0.7 Voc threshold needed was subtracted so that the transistor could be turned on. Additionally, in the process of the experiment, R3 was increase to 5.1 kilo ohms  (Xie and Shi, 2010). The function of R3 on this case was to limit the current that went into the base, therefore, reducing the collecting current which later increased voltage via the collector. One of the limitation that was experienced is that when the Vs exceeded 0.21 , Vb started to experience some distortion and the highest and the maximum voltage had already been reached. The corresponding graphs for the experiment is as shown in the diagram below

From the graph it is all evident that the peak value are in a constant trend this is unlike the AC gain which decreases with an incease in the peak values.
Planning Gannt Chart
The design, implementation, and testing of the timer took 45 days. Some of the tasks carried within the time frame include concept generation, concept selection, cost estimation, top down design, simulation, integration, review, resting and then release. The summary of the start, duration, and end date are tabulated below. The Gannt chart also provides a visual representation of the tasks associated with the design, implementation, and testing of the timer.
