      As I mentioned in the original discussion. Good.

      A design cannot be good if it does not meet its objectives and therefore perform successfully. So if being safe too is a criteria of success, then it must also be safe.

      A design which is just safe, may not fulfil any other useful criteria and therefore may not be good.

      Other criteria for a good design may be down to manufacturability, saleability in the market place, appropriate choice of and economic use of material, energy and labour time, long life and ease of recycling at its end.

      All of this depends on its original purpose and the necessary statutory standards which govern the item in question.

      Probably best to start a new thread. That could be a juicy argument :D

      In a sense, a good design, one must make safety requirements, be considered the last is a good design. :D

      Some Good Designs relies only on costs and efficiencies.

      I feel that a good design includes safety . Take the chainsaw, the inclusion of a chain brake makes an inherantly dangerous machine somewhat safer without impinging on performance.

      Another is a grip safety on a handgun. I think we can all agree it is a dangerous tool, but if it can't be fired unless you have a good grip on it to maintain control, then the tool is safe. It is only the operator that provides the danger.

      I design thermal processing equipment with heat inputs upwards of eighty milion Btu. It must perform the function, but safety is always first on my list of priorities.
