Dieter Rams:
ten principles for good design

Back in the late 1970s, Dieter Rams was
becoming increasingly concerned by the
state of the world around him – “an
impenetrable confusion of forms, colours
and noises.” Aware that he was a
significant contributor to that world, he
asked himself an important question: is
my design good design?

As good design cannot be measured in a
finite way he set about expressing the ten
most important principles for what he
considered was good design. (Sometimes
they are referred as the ‘Ten
commandments’.)

Good design is          The possibilities for innovation are not, by
                                                      any means, exhausted. Technological
                              innovative              development is always offering new
                                                      opportunities for innovative design. But
                                                      innovative design always develops in
                                                      tandem with innovative technology, and
                                                      can never be an end in itself.

Good design            A product is bought to be used. It has to
                                                      satisfy certain criteria, not only functional,
                               makes a                but also psychological and aesthetic.
                                                      Good design emphasises the usefulness
                               product useful         of a product whilst disregarding anything
                                                      that could possibly detract from it.

Good design is          Products fulfilling a purpose are like tools.
                                                      They are neither decorative objects nor
                              unobtrusive             works of art. Their design should therefore
                                                      be both neutral and restrained, to leave
                                                      room for the user’s self-expression.

  • 8. Industrial Design Vs. Engineering Design KEITH VAUGH
  • 9. Dieter Rams: ten principles for good design Back in the late 1970s, Dieter Rams was becoming increasingly concerned by the state of the world around him – “an impenetrable confusion of forms, colours and noises.” Aware that he was a significant contributor to that world, he asked himself an important question: is my design good design? As good design cannot be measured in a finite way he set about expressing the ten most important principles for what he considered was good design. (Sometimes they are referred as the ‘Ten commandments’.) Vitsœ’s designer, Dieter Rams. Photograph by Abisag Tüllmann source: https://www.vitsoe.com/gb/about/good-design
  • 10. Good design is The possibilities for innovation are not, by any means, exhausted. Technological innovative development is always offering new opportunities for innovative design. But innovative design always develops in tandem with innovative technology, and can never be an end in itself. TP 1 radio/phono combination, 1959, by Dieter Rams for Braun source: https://www.vitsoe.com/gb/about/good-design KEITH VAUGH
  • 11. Good design A product is bought to be used. It has to satisfy certain criteria, not only functional, makes a but also psychological and aesthetic. Good design emphasises the usefulness product useful of a product whilst disregarding anything that could possibly detract from it. MPZ 21 multipress citrus juicer, 1972, by Dieter Rams and Jürgen Greubel for Braun source: https://www.vitsoe.com/gb/about/good-design KEITH VAUGH
  • 12. Good design is The aesthetic quality of a product is integral to its usefulness because aesthetic products we use every day affect our person and our well-being. But only well- executed objects can be beautiful. RT 20 tischsuper radio, 1961, by Dieter Rams for Braun source: https://www.vitsoe.com/gb/about/good-design KEITH VAUGH
  • 13. Good design It clarifies the product’s structure. Better still, it can make the product talk. At best, makes a it is self-explanatory. product understandable T 1000 world receiver, 1963, by Dieter Rams for Braun source: https://www.vitsoe.com/gb/about/good-design KEITH VAUGH
  • 14. Good design is Products fulfilling a purpose are like tools. They are neither decorative objects nor unobtrusive works of art. Their design should therefore be both neutral and restrained, to leave room for the user’s self-expression. Cylindric T 2 lighter, 1968, by Dieter Rams for Braun source: https://www.vitsoe.com/gb/about/good-design KEITH VAUGH
  • 15. Good design is It does not make a product more innovative, powerful or valuable than it honest really is. It does not attempt to manipulate the consumer with promises that cannot be kept. L 450 flat loudspeaker, TG 60 reel-to- reel tape recorder and TS 45 control unit, 1962-64, by Dieter Rams for Braun source: https://www.vitsoe.com/gb/about/good-design KEITH VAUGH
  • 16. Good design is It avoids being fashionable and therefore never appears antiquated. Unlike long lasting fashionable design, it lasts many years – even in today’s throwaway society. 620 Chair Programme, 1962, by Dieter Rams for Vitsœ source: https://www.vitsoe.com/gb/about/good-design KEITH VAUGH
  • 17. Good design is Design makes an important contribution to the preservation of the environment. It environmentally conserves resources and minimises physical and visual pollution throughout friendly the lifecycle of the product. 606 Universal Shelving System, 1960, by Dieter Rams for Vitsœ source: https://www.vitsoe.com/gb/about/good-design KEITH VAUGH
  • 18. Good design is Less, but better – because it concentrates on the essential aspects, and the as little design products are not burdened with non- essentials. as possible Back to purity, back to simplicity. L 2 speaker, 1958, by Dieter Rams for Braun source: https://www.vitsoe.com/gb/about/good-design KEITH VAUGH

  6. Thats the major question we are going to attempt to answer over this academic year, through both the Computer Integrated Design and Manufacture Modules. We’ll approach this problem is a very systematic and logical manner. The assignments in each module will assist in developing this understanding. These assignments are designed so that they follow the weekly lectures and therefore should be worked on after each lecture is delivered. Furthermore each assignment follows on from the previous and conclusions you draw from each is the direct input into the next. \n

  18. So what is this statement really saying to us?\n\nThe Design Process is creative\n\nEngineering students gain a vast amount of theoretical material and information during their academic career\n\nTheir weakness is logically applying this to a specific task\n\nIt is perfectly adequate to find a solution along conventional lines\n\nFailure is common when faced with designing something new\n\nThe design process is a systematic approach to design\n\nMost Important is identifying a customer need! Yes customer need is what drives NPD\n
  19. Really this can be summarized as the adaptation of existing designs where relatively minor changes are made at each iterative stage. Some will claim that there are branches of manufacturing where development as practically stopped, so there is virtually nothing for the designer to do except make minor modifications. Design activity of this kind requires no special skills and the problems encountered are relatively easily overcome with ordinary technical training. \n\nLets consider one of the most iconic consumer items of the decade. Since its introduction in 2001, the iPod has seen 5 separate adaptations, well six actually if you include the new announcements on Wednesday! \n\nThis adaptive design approach has helped Apple Inc. to remain at the forefront of the MP3 player market. Since its introduction, Apple has seen there shares increase from approximately $19.00 to $138.00 Today. There is no doubting it is a high quality and the marketing campaign has been highly effective. It is clear to see that Apple Inc have there eye firmly on its central underling technology of iTunes. I won’t be surprised if I see this becoming central to future products. All you have to do is look at how it manages, music, photos, contacts, your calendar and delivers all these to various media devices, including the iPod, Apple TV and most recently the iPhone!

The integration of other functional areas with the design process helps discover hard to solve problems at the design stage. Thus, when the final design is verified it is already manufacturable, testable, serviceable, and of high quality. The most distinguishing feature of concurrent engineering is the multidisciplinary, cross functional team approach.\nA typical flow diagram for an organisation employing concurrent engineering is \n

  159. The past 10 years has seen a significant increase in the number of tools/technologies that are available to all areas of engineering. Significant advances has been achieved in the optimisation of all activities from design through, manufacture, and even to level of product disposal at the end of its service life.\n\nThe cost of implementing some of these technologies has seem a significant decrease. Consider the CAD sector for example! In early 90’s a seat of CAD software for solid modeling and assembly purposes only cost in the region of 16 - 20K euro’s. By the turn of century, that cost had decreased to approximately 6K euros where it remains. Similar comparisons can be drawn in the fields of Computational analysis, Rapid Prototyping tooling etc....\n\nThis has resulted in the more and more manufactures aspiring to World Class Manufacturing strategies.\n
