Product Design Analysis Of Cork Extractor Engineering Essay

Ever since adult male has cared about vino, he has cared about cork to maintain it safely sealed in bottles. A corky bottle creates a demand: it is the demand to acquire entree to the vino indoors. To make this he had to contrive a device. This device is the cork extractor.

The development of such a merchandise may look simple, but it requires a figure o stairss that has to be considered and implemented by the design or development squad. The undermentioned analysis shows the factors which might hold been considered by the design or merchandise squad within each stage of the undertaking.

B. Product Design Analysis

1. Probe

1.1 Purposes and Aims

As it is said above, the purpose is the design of a cork extractor that fills the market demand. Design will be concentrated in a few facets such as merchandise functionalities, biotechnologies, stuffs choice, cost and safety.

1.2 Market Investigation

To place the market demand, the squad has to, exhaustively, research the market. Market research is a really of import portion of the design procedure because it is the footing for a good structured and complete merchandise design specification and therefore a successful merchandise development.

The most of import portion of the market probe is the clients, those who are traveling to utilize the cork extractor.

This research may include:

  • Who are that clients ( age, sex, business, etc. ) .
  • Where are they ( national, international market ) .
  • What they like and dislike about current cork extractors.
  • Market size.
  • Gross saless size.
  • Customer ‘s suggestions for farther development of current cork extractors.
  • Datas about makers, providers and discoverers.

In order to pull and retain clients the squad needs to understand its competition. Hence they likely contact a research that involves their rivals and the types of cork extractors they produce.

Another important portion of the market research is the aggregation of information that is related to the current engineering of cork extractors. This is an probe about the on the job rules, the form, the stuffs and cost. For illustration,

  • There are devices that use a inexpensive prison guard to convey a prescribed burden to the cork.
  • There are devices that use a light lever to transport a prescribed bending minute.
  • There are devices that use a slender elastic blade that will non clasp when driven between the cork and the bottle cervix.
  • There are devices that use a thin, hollow acerate leaf, stiff and strong plenty to perforate a cork.

A utile beginning for this probe is patents on old innovations. Figure 2 shows some of these patents.

From this probe the squad can calculate out whether the current engineering is in low cost, safe, familiar to the clients, in high quality or non. Therefore, they can take advantage of the possible drawbacks and seek to better them.

Surely, they team would desire to hold competitory advantage after the cork extractor launch into market. To win this, the squad would likely reach a research on the merchandise the monetary value, the topographic point and the publicity ( 4 P ‘s of selling ) :

  • Merchandise: Which are those features, belongingss and value ( useful, sentimental ) ?
  • Monetary value: Which is that monetary value that is relative to the quality of the merchandise?
  • Topographic point: Geographic coverage, appropriate merchandising points.
  • Promotion: Ad, personal merchandising, promotion, gross revenues publicity.

A technique that might be used by the squad to guarantee that the cork extractor that is under development is the 1 that the client wants is the Quality Function Deployment. The technique is about interpreting the client ‘s demands into prioritized demands at every phase of the merchandise debut procedure.

Ones the squad gathers all these informations continues with the most of import phase of the procedure, the merchandise design specification based on the market needs. In this phase the squad sets the aims and constrains.

2. Product Design Specifications

In this phase of merchandise design, the squad needs to depict exactly what the merchandise has to make. This description is based on the market needs. Each one of these demands must be contemplated and the squad has to see which feature is precise plenty and which is the value of this characteristic that reflects the demand. Therefore, every specification consists of a metric and a value. It is indispensable that all facets of the design are considered, or at least those that are important for the development of the merchandise, in this instance the development of a cork extractor.


The public presentation is the most of import portion to be specified for every merchandise. There are many demands for the cork extractors that have to be turned into specifications. For illustration:

  • The work should necessitate as small beastly force as possible.
  • The cork should be kept integral ( no shredding, breakage, etc. ) .
  • The cork extractor should travel in directly to avoid interrupting the cork.
  • The drawing action should non agitate up the bottle to avoid upseting the deposit.


Another of import portion is the analysis of the stuffs by which the cork extractors are traveling to be made. The squad has to find those specifications that fill, for illustration, the undermentioned demands:

The cork extractor should be:

  • Light
  • Tough
  • Avoid oxidization
  • Avoid corrosion
  • Non-toxic
  • Reclaimable


Most of the bing cork extractors have crisp borders and are unsafe to kids. So, one of import specification could be referred to the being of a safety. Besides the cork extractor must make the occupation safely, intending that detonations, checking glass etc. , must be avoided.


The bottles which are sealed with cork are in many types, so the cork extractor has to suit all these types of bottle cervixs.


The cork extractor is one of the devices which are necessary to many topographic points ( houses, eating houses etc. ) . Therefore, it is indispensable that everyone can afford it. So it would be good to put an upper bound for the monetary value ( for illustration, ?60 ) .


Such devises should be maintenance-free.


By and large, the cork extractor should be comparatively light. The squad, after consideration will put an upper bound for the weigh.


It would be utile if the squad determines the market ( where it will be sold, how, typical utilizations ) .

3. Conceptual Design

After the squad has set the demands for the aims and restraints, the following measure is the conceptual design phase. This phase begins with the coevals of many thoughts about the merchandise.

3.1 Concept coevals

At this phase the squad gathers together to bring forth thoughts that meet the demands of the merchandise design specifications. The coevals of these thoughts may be separately first ( by each one of the squad members ) and so garner them all together. For the originative thought to be stimulated the squad may utilize drawings or studies, experience of each member and decidedly treatment.

The following measure is the manifestation of the generated thoughts. That can be done diagrammatically, graphically and through mold. Totaling the constructs will assist the squad to measure them subsequently.

3.2 Concept rating

The following measure is the comparing and rating of the generated thoughts. For this intent the squad might utilize the Pugh ‘s rating matrix, which compares the constructs against the standards for rating. The standards derive from the PDS. An illustration of the matrix is shown in Figure 3.















































Figure 3.Evaluation matrix ( 1 ) .

  • Datum is the construct with which all other constructs are to be compared.
  • Plus means better than, less than, etc, comparative to the data point.
  • Minus means worse than, more expensive than, etc. , comparative to the data point.
  • S ( same ) means same as data point.

By this method, the weakest constructs are eliminated from the matrix and merely the strongest 1 remains ( 1 ) .

3.3 Concept development

The staying construct is developed and the phase ends with a layout or scheme drawings and CAD theoretical accounts like the followers:

4. Detail design

During this phase the squad is pulling up specifications for each constituent of the cork extractor. Since all constituents carry a burden, critical 1s have to be subjected to precise mechanical analysis. This is indispensable due to the fact that all constituents must prolong the applied burden. For illustration, the constituent of the cork extractor that has to be subjected to mechanical analysis is the grip on which the user applies force and the prison guard.

The squad has to be certain that the cork extractor is traveling to be dependable, in good quality, and without failures. Thereby, optimisation methods are applied to maximise public presentation. An illustration of such a method is the Failure Mode and Effects Analysis ( FMEA ) . After that, the squad chooses the stuffs of which the constituents are traveling to be made. A tool that would likely be used by the squad to take the stuffs is the Cambridge Engineering Selector ( CES ) . The phase ends with the readying of elaborate drawings and certifications such as user manuals.

5. Industry

Once the development squad has the elaborate drawings and all the informations, together with the fabrication squad decides which is traveling to be the fabrication procedure. This is an of import undertaking. The pick depends on the stuffs of which the cork extractor is traveling to be made, on its size, form and preciseness. Therefore, the squad has to look back to the design specifications. Besides, the pick depends on the procedure cost and back uping information. Again the squad has to make a research on instance histories and documented experience. To avoid the high cost from a possible failure of the merchandise it would be indispensable for a paradigm to be developed. This paradigm has to be tested to be certain that it ‘s non traveling to neglect and by and large if it meets the design specifications. This testing can be done utilizing the Finite Element Analysis ( FEA ) . By this, high cost and unneeded labour is avoided. After the testing, if everything is all right, the design procedure passes to the concluding development phase. The concluding merchandise could be the 1 that follows:

6. Gross saless, service

Once the merchandise is finished and takes its topographic point into the market, another undertaking has to be done: it ‘s the feedback from the clients. The squad collects information that is related to: merchandising, market impact, competition. This gives the oportunity for alterations and farther development./p & gt ;
