Chapter 8.9, Problem 2P

Compare (a) the systematic design process that leads to a morphological chart with a large number of possible solutions with (b) a design process, in which the problem is identified and then a brainstorming session is started to generate different solutions. Which of these methods would you use. Why? In the event that a certain aspect of the design needs modification, which of the two methods would be easier to apply toward that modification. Why?

Expert Solution & Answer
Check Mark
To determine

The comparison between design process by morphological chart and brainstorming session.

Explanation of Solution

The steps to be followed in the morphological chart are shown below.

  • • Extract all purpose functions: The product has to perform these high level functions, they will be near to the root in the function tree. They occupy the first column in the left in the morphological chart.
  • • Develop concepts for each function: In this step the aim is to produce as many concepts as possible for the functions that have been identify.
  • • For each functions or sub function lists all method that is to be used: In this step, the alternative solution for the problem is listed down. For example to lift the body, you can use different equipment like ladder, screw and rack and pinion arrangement etc.
  • • Draw the chart containing possible sub solution: The chart formed in this step is called morphological chart. This chart specifies all possible solution for the given problem.
  • • Identify feasible combination: All the solution that has been listed may not feasible, in this step the feasible region is identify.

The figure below shows all possible solution with the feasible solution.

Brainstorming:

In this method large number of ideas from the group of people is listed down in the shorter time. The principle is that when there are many ideas, the chance that there will be better idea among them is higher than when there are few ideas.

Some features of the brainstorming is listed down:

  • • The leader should clearly state the purpose of the brainstorming session.
  • • All participants should tell their solution to the leader.
  • • All the ideas are recorded on a flipchart so that all members could see them.
  • • After all ideas have been listed, clarify all ideas and eliminate the one which are duplicate.

Both the method can be useful depending upon the situation.

In the event that a certain aspect of the design needs modification brainstorming method would be easier to apply towards that modification because in this method large number of ideas from the group of people is listed down and thereby the best possible outcome can be reached in the shorter time.

Quality has been defined as customer satisfaction (or "fitness for use"). Quality can also be defined as "conformance to specifications". In theory, if you create the right specifications and then manufacture a product that meets these specifications, you should achieve customer satisfaction.  Consider the following four scenarios for a particular product: A) Conforms to specifications and is competitive in its adequacy.   B) Conforms to specifications and is not competitive in its suitability.    C) It does not conform to specifications and is competitive in its education.   D) Does not conform to specifications and is not competitive in its education.   Which of these are not, in theory, feasible, but in practice occur and cause a lot of conceptual confusion?  Can you cite some examples?
You are a biomedical engineer working for a small orthopaedic firm that fabricates rectangular shaped fracture fixation plates from titanium alloy (model = "Ti Fix-It") materials. A recent clinical report documents some problems with the plates implanted into fractured limbs. Specifically, some plates have become permanently bent while patients are in rehab and doing partial weight bearing activities. Your boss asks you to review the technical report that was generated by the previous test engineer (whose job you now have!) and used to verify the design. The brief report states the following... "Ti Fix-It plates were manufactured from Ti-6Al-4V (grade 5) and machined into solid 150 mm long beams with a 4 mm thick and 15 mm wide cross section. Each Ti Fix-It plate was loaded in equilibrium in a 4-point bending test (set-up configuration is provided in drawing below), with an applied load of 1000N. The maximum stress in this set-up was less than the yield stress for the Ti-6Al-4V…
O You are running an industrial research study together with your project team to improve energy efficiency in a combustion process. The purpose of the research is to identify the optimum air-fuel ratio for the combustion process in a boiler under varying conditions of air supply and quality of fuel. The study would involve design of experiments, data collection and analysis, simulation of the different variables and validation of the optimum parameters. There is a lot of pressure to improve the energy efficiency as there is a forecast of fuel price rise in the forthcoming month. Based on the CRPE code of ethics, explain two critical precautions which the engineers have to consider before implementation of the data collection process for the industrial experiment. to be taken during the Describe briefly five ethical measures experimentaldata collection in order to ensure validity of results. Explain two precautions to be taken during the report writing on the research study carried out…
