Technical Report

For this project, our main objective was to dissect, analyze, and understand the inner workings of a Black and Decker reciprocating jigsaw. On a broader scope still, we were to determine the different components of the jigsaw and conclude the various interactions between these components. A side purpose for this project was to introduce the members to a group working environment, and to learn the kind of communication and dependency needed for any sort of group work in the engineering field. The project was divided into four distinct sections during this analysis process; Project planning, Product dissection, product analysis, and Product Explanation. Each gate focused on the skills needed for a proper and global understanding of what goes into a product, its design, and its physical manufacturing.


Gate one was directed towards the planning of the project. For this step we had to divide the tasks of the project among the group members, to assign responsibility to each member so that no single member would be in charge of taking care of everything. Once our roles were settled, we moved to planning the actual process of dissecting, assembling, and the overall study of the product itself. For this we had to discuss meeting times that worked for everyone, as well as frequency and location. Along with our personal organization, we had to understand the product and conduct research in order to better understand what kind of skills, time, and product specific information we would need to complete this project.


Gate two was the start of our physical dissection of the product. After having created a sound virtual understanding of our product, the next step was to physically dissect the product and note each step in order to make it extremely simple for anyone to mirror our dissection. This allowed us to physically see the connection between the functions and follow the flow of energy throughout the product. Along with the dissection of the product, we were able to act on our original work and management plans, and make the necessary adjustments and changes when things were not working out as planned.


Gate three Is where the true engineering took place. At this stage in the project, we were to look at the individual components and determine their manufacturing process and discuss why these particular processes were used, and what components of the parts allowed for these processes to be ideal. We were to look as the products part with the engineering mindset; function, how to create components in the most efficient and profitable manner. An example of the analysis process was used as well for a single key component of the product, in order to show how it would be used in the design or testing stages of the design process. Virtual modeling was also introduced in this gate with the requirement of a CAD model of individual component.


Gate four was the re-assembly process, as well and the design revisions that we would potentially change about our product. At this stage in the project we are fully knowledgeable about our tool and how the majority of the interactions and connections work. Having this knowledge we are able to stretch our minds and create a design change for the product at the system level. While doing this we were to keep the four factors in mind, and change the product in such a manner that it would be beneficial to one or more of these factors.


This project not only demonstrated to us the amount of engineering and knowledge necessary for the design of any product, but it also emphasized the importance of group cooperation and the need for good group skills. We were able to develop an understanding of the importance of technical communication and in delivering the required information in a neat, coherent, and direct manner.
