Concept explainers
As technology advances and new materials are synthesized, there are certain products that receive only minimal, if any, modernization attempts. Among them are the shopping carts used in grocery stores. There is a tendency to save parking spaces by not designating a return cart area. Leaving carts in the parking lots may lead to serious accidents and car damage. Furthermore, although many customers do not fill their carts that much when t shopping, they do not like to carry baskets. Other customers like to sort products as they shop. Develop an objective tree to clarify the need statement and prioritize the objectives laid out in the problem statement. You may add features that may not be listed clearly in the problem statement but will give an additional advantage to the proposed design.

ENGINEERING DESIGN PROCESS
- Foxconn operates a network of factories across the Chinese mainland employing 1.2 million people, that makes products for tech companies that include Apple, Hewlett Packard, and Dell. The electronics manufacturing giant has been on a steady course for a while to replace man power with robotic systems. “Foxconn (has) vowed to install up to 1 million robots in its factories over the next three years, which analysts suggested was in part to address long-time scandals such as high suicide rates among employees and exploitation of workers.” Foreign manufacturers in China are also viewing upgrades as vital to their operations in the country. In fact, numerous multinational companies have recognized the long-term benefits of replacing human labor with robots. 1- Many companies outsourced their manufacturing activities to Foxconn due to its low labor costs. Does Foxconn’s shift to automation make it likely that some of those companies will reconsider outsourcing in favor of shifting to…arrow_forwardMachine design,arrow_forwardFind a product with good anthropometric considerations in design.

- Do engineers and scientists ever get involved in product liability and product recall matters? If so, in what way?arrow_forward11)Q1. How do you evaluate manufacturing process?arrow_forwardA company uses various machines in the preparation of ice cream. The firm has been successful until recently when it noticed growing repair expenses for the various machines it uses. Over the past 20 months, the machines have broken down at the rate indicated in the following table: Each time a machine breaksdown, the company estimates that it loses an average of US$300 in production time and service expenses. Should the company opt to purchase a service contract for preventive maintenance by Angeles Machineries Inc., (AMI) there will still be breakdowns, averaging one breakdown per month. The price for this service by AMI is US$150 per month. a. If the company continues as is, what is the expected no. of breakdowns based on past history? b. What will be the cost of breakdowns per month to the company without a preventive maintenance contract? c. What will be the cost of breakdowns per month to the company with a preventive maintenance contract? d. Should they engage the…arrow_forward
- c. The life of a manufactured product is assumed to have gone through eight (8) stages. List and explain all stages using diagrams where necessary.arrow_forwardA product line has two models: X and Y. Model X consists of 4 components: a, b, c, and d. The number of processing operations required to produce these four components are 2, 3, 4, and 5, respectively. Model Y consists of 3 components: e, f, and g. The number of pro-cessing operations required to produce these three components are, 6, 7, and 8 respectively.The annual quantity of Model X is 1,000 units and of Model Y is 1,500 units. Determine the total number of components and processing operations associated with these two models.arrow_forwardA process currently services an average of 59 customers per day. Observations in recent weeks show that its utilization is about 90 percent, allowing for just a 10 percent capacity cushion. If demand is expected to be 70 percent of the current level in five years and management wants to have a capacity cushion of just 4 percent, what capacity requirement should be planned? The needed capacity requirement is nothing customers per day. (Enter your response rounded up to the next whole number.)arrow_forward
- A drug store sells 30 bottles of antibiotics per week.Each time it orders antibiotics, there is a fixed ordering costof $10 and a cost of $10/bottle. Assume that the annualholding cost is 20% of the cost of a bottle of antibiotics, andsuppose antibiotics spoil and cannot be sold if they spendmore than one week in inventory. When the drug store placesan order, how many bottles of antibiotics should be ordered?arrow_forwardYour company decided to manufacture different types of pencils like wooden, metal bodyand Elasto-plastic body. (see the following pictures as an examples). Your manager assigned a taskto design the complete manufacturing plan for the following products:-a. Picture a is wooden type pencilsb. Picture b is metal body pencilsc. Picture c is plastic/polymer body pencilsYour design of process must start from a raw product and ends on the final finished product. Clearlywrite the method which you adopt for manufacturing purposes and its pros and cons for theseproducts. You must justify that why you are choosing this method. Also draw the sketch of your dieor mold or pattern and upload the picture in your response. Take the dimensions wisely.arrow_forwardBriefly explain the following basic steps in manufacturing processes 1). Marketing 2). Production quality control 3). Sourcing the raw material 4).
