Gate 5: Bissell PowerForce® Bagless Upright Vacuum 6579-2 Product Delivery
From GICL Wiki
- The Bissell 6579-2 vacuum was designed and manufactured to be an economically viable vacuum cleaner for various homes at the price of only $65. Throughout the semester, our team disassembled the vacuum to understand more about the components and design considerations that went into it. We observed all inferred details of the vacuum without tools, and predicted the identification of components and required tools for disassembly. Then we disassembled the product with some simple tools, such as screwdrivers and pliers, to identify potential problems and to obtain a greater understanding of the inner processes of this vacuum.
- Before the dissection, group 12 derived several conclusions. First, the outer cover is made from highly durable plastic that protect the user from any dangerous component in the cyclone assembly and filter system. Also, the use of a dark navy color allows the user to focus less on the aesthetics of the vacuums looks and worry more about its routine maintenance. In addition, we observed that the Bissell vacuum uses the electricity from an outlet to the motor to get enough power for a high suction force.
- Another procedure completed prior to the dissection of the vacuum in gate 1 was to create a functional model chart (Figure 2). The primary function was to clean the floor or carpet. This function can be broken down into sub systems that contain importing human energy, air/debris, separating debris from air, and transferring the electrical and mechanical energy into pneumatic energy. In addition, there were various sub functions that followed after the secondary functions. These included more specific functions such as suction the floor brush or hand tools.
- For gate 2, we found that all of the components are connected with each other in a linear manner. The motors rotational energy transforms into translational energy from the rubble belt and then transforms back into rotational energy at the brush. Gate 2 also gave group 12 a better understanding of our product's parts and subsystem arrangements. In this section the group did a section on product Archaeology involving a complete dissection of the Bissell 6579-2, as well as, a detailed list of steps to take the vacuum apart. In addition, the group provided a Preliminary Project review and also answered some basic questions on the dissection itself, as well as, the Vacuums subsystems and overall functions. The objective of Gate 2 was to successfully dissect and provide details for the Bissell Vacuum's functions and subsystems.
- For gate 3, our group completed a full analysis of the Bissell vacuum. We achieved this by studying each individual component with high level of detail. In this section we addressed many questions such as; what material is the component made from, how it was manufactured, and we even asked ourselves what design changes we would make to the components and subsystems. In gate 3, we found a lot of good information’s about our product, such as how all the part are made, which material was used to manufacture all components and how complex each part was.
- This section includes our detailed product reassembly and system design revisions. The product reassembly describes the chronological process of reassembling the Bissell 6579-2 vacuum cleaner. Each step included which tool was used, how difficult it was to assemble, and if there were any challenges met with that particular step. The three design revisions explain an additional feature revision or an elimination feature revision on a system level of our product. During the disassembly and reassembly of the product, the group analyzed the global, societal, environmental and economic factors that went into designing the product and its components.
Gains and Experiences
- The findings that Group 12 has discovered during the entirety of this project are numerous. In terms of actually doing the project, each group member has gained much experience in how to function with others as a team. Group members were each given a different role and their own value that contributed to the project as a whole. In terms of the product, dissecting, analyzing, and reassembling the Bissell Power Force® Bagless Upright Vacuum 6579-2 had taught everyone in the group about actual applications of technical systems. It has also given the group hands-on experience that is useful in all engineering jobs and applications.
- Another large contributing factor to the learning of the group with respect to the design and manufacturing process was the portion of the project where the team was asked what changes they could make to the product to improve it as well as some design considerations of their own. The group was able to come up with ideas and brainstorm about how they would work and what was needed to make them happen, as well as, how easily they could be implemented. With a better understanding of the vacuum and how it works, this gave the group a chance to question the design process and further understand why certain decisions were probably made during the original design of the Bissell vacuum. The team, in coming up with the new ideas was probably asking themselves the very questions that most of the original engineers were asking during the design, giving the group a great example of what an engineer is faced with and what the type of decisions they need to make during the design process.
- A smaller, but equally important part of the project was the management of the team and planning the execution of the work at hand. The project provided a great way for the team to better their abilities to work in a group and manage a team while dealing with other work from different classes. The group management portion of this project gave the group a chance to formulate a plan, execute that plan to the best of their ability and make sure that all operations went smoothly. This was a great addition to the learning experience of the project, no engineer is ever going to design something all by himself, so working with a group gave the team a chance to work together and learn how to make the best of their resources. Working as a team and managing a project to it completion is a necessary skill and this semester group 12 was able to hone that skill in a most positive way.
