Scenario

An activity requiring learners to research and/or visit a design department and investigate the relationship between designer and customer and also requiring learners to research legislation and standards that apply to two different products as well as the manufacturing, environmental and sustainability constraints for one of them.

 

Task 1

Success in the marketplace can only be achieved if manufactured products are fit for purpose, marketable and meet customer requirements. This task investigates how this can be made to happen.

Arrange to interview an engineering designer who works in a local company and find answers to all of the following questions:

1. When designing a new product or carrying out a modification to an existing one, what triggers the design process?

2. What communication is there between the designer and the manufacturing engineers who will be planning how the product is to be made in the workshop?

3. When designing and planning the production of a new product, decisions have to be made about the viability of the project and whether or not to go ahead with it. How are these decisions arrived at and who is involved in making them?

4. What technology does the designer use when carrying out their job, e.g. CAD and simulation software?

5. In addition to communicating with the customer and manufacturing engineers, who else does the designer communicate with?

6. What systems are in place to ensure that the company’s relationship with a customer remains a positive one throughout the design, manufacturing and working life of the product being sold to them?

Your evidence should be presented in the form of a report describing how the design process operates. You may find it useful to include relevant flow charts.

 

Task 2

You are a design engineer and have been asked to work on a new project for a customer who has bought from your company on previous occasions. A good relationship exists between the two parties and the starting point for the new product is an overview and rough outline sent in to you by the customer. They ask that you look at their proposal and work it up into a PDS that can be discussed and evaluated at a meeting to be held fairly soon. If they are happy with the PDS, the next step will be to ask you to prepare some design proposals.

The customer who you will be working for manufactures and supplies equipment to schools and colleges and has sent in the following overview of what they want.

RALK Computers has identified that there is a great market for hand held gaming device. Games such as flight simulator and car race are currently in high demand. KEHN Electronics, a company which manufactures electronic gadgets and animation software is granted the contract by RALK Computers to manufacture a brand new hand held gaming device. A total of 100,000 units

A total of 100,000 units are to be manufactured by end of May. The selling price of each unit will be AED 400. To enable online gaming, the device should connect to internet using WiFi. The device should meet all the relevant EU standards and legislations which help RALK to sell the product to a wider market. As a design engineer for KEHN Electronics, you are asked to meet RALK Computers representatives regularly and document your progress as

As a design engineer for KEHN Electronics, you are asked to meet RALK Computers representatives regularly and document your progress as report.

  • Interpret this requirement and put together a draft PDS which includes documented information about parameters such as physical configuration, materials, mass, operating performance.

 

  • Discuss the draft with the customer, negotiate any changes asked for and come up with an agreed specification (your teacher/tutor/design engineer to assume the role of the customer).

 

  • Re-write the draft as a finished PDS. For this activity you will need to make a transcript of your discussions with the customer and also obtain a witness statement to support your evidence.

Task 3

To build up a good relationship with a customer takes time but a single mistake with a product can very easily undo all this good work.

Write a document  explaining the possible impact of a poor design process on customer relationships and requirements, making reference to two documented case studies that relate to real products.

 

Task 4

Engineers are very good at designing products but success in the marketplace can only be achieved if these products are fit for purpose and conform to standards. Before a new domestic airline or motor vehicle can be sold they have to be tested and their designs proven against a set of internationally agreed criteria.

You can find information about the Certificate of Airworthiness on the Civil Aviation Authority (CAA) website: http://www.caa.co.uk

To achieve certification for a new plane the manufacturer has two options:

  • wait until the plane is totally finished and then ‘go for broke’, hoping that it passes scrutiny
  • Involve the CAA at the design stage and take counsel from them.

 

This assignment investigates how companies can get it right first time. Portable 110/240 Volt generators are now widely available for domestic and trade use. A typical unit consists of a small petrol engine, drive coupling, alternator, voltage regulator and switch circuits. They are on sale to the general public in many DIY stores and over the internet. Click on the following link to see an example of one:

Describe three legislation and three standards which have to be considered when designing this type of product.

 

Task 5

Describe the environmental, sustainability and manufacturing constraints which must be considered as the design work enters its final stage and production drawings and manufacturing schedules are being created. In doing so you should consider the use of energy and manufacturing resources, impact on the environment, end-of-life disposal, material properties and methods of manufacturing including health and safety aspects.

 

Task 6

The legislation and standards that apply to the design, manufacture, operation and disposal of products are always under review and subject to change. Companies that sell into the world marketplace must be sure that their business operations and products meet the requirements that relate to global manufacturing and selling. The design of a new product may be technically brilliant but if it falls foul of changing legislation, it will have to be withdrawn from sale and this will have serious financial repercussions for the company. On a fairly regular basis recall notices appear in newspapers asking customers to return products that are substandard so that they can be modified or the customer refunded.

The environmental standards relating to aircraft and motor vehicles get tougher all the time and where the lead time for designing and manufacturing a new product is large, designers need to think well ahead and perhaps even take a gamble on the next ‘set of hurdles’ that they face. A wrong decision could trigger a heavy financial penalty; a well anticipated action could bring high financial rewards. Think about the debate over four-wheel drive ‘gas guzzling’ vehicles – what type of vehicle should the car companies be offering us in ten years’ time?

Put together an evaluation  of the impact of legislation and standards on the design process in relation to the impact on the profitable of the business.
