Pringles are a beloved snack well-known for its addictiveness (“Once you pop, you can’t stop“). There are a few other interesting factors that set Pringles aside from other potato chips.
Firstly, Pringles have been called many things, because it is not strictly a potato chip. When it first debuted, other snack companies complained that it was not technically a potato chip as they were made from dried potatoes, so they were labelled “potato crisps“. Ironically, the company successfully argued in 2008 that Pringles were not “potato crisps”, using the logic that they were not of natural shapes and only contained 42% potato as they are made from potato-based dough. This was so that they could avoid the British tax on potato crisps.
Secondly, Pringles chips have a characteristic saddle-shape, known in mathematics as a hyperbolic paraboloid. This creates a uniform shape, meaning they can be stacked neatly in a tubular container for efficient and reliable packaging, as opposed to most potato chips that are packaged in bags. Furthermore, the shape is structurally sound, preventing the chips from breaking under the weight of the stack.
Finally, the inventor of the cylindrical container was a chemist named Fredric Baur, who started the process of making Pringles. His dying wish was to have his ashes buried in a Pringles can and this wish was respected by his children.
You would think that the more freedom the designer has, the more their creativity can flourish and they can produce more original, greater ideas. But it is a well-known fact in the design world that the the best designs are produced when designing under constraint.
Consider the beauty of the canal houses of Amsterdam. In the 17th century, plots of land by the canal were allocated in narrow (but deep) portions to maximise the number of houses. Architects worked around this restriction, resulting in the narrow, tall houses of various shapes and colours that we see today. Another architectural example is Florence and Santorini, where building materials were limited to red bricks or stone painted in white and blue respectively, meaning the buildings shared a consistent colour scheme, while varying in shape – the ideal combination for building a beautiful city.
We see the same in other fields. Photography is limited in the realm of time, as you can only take a snapshot. But by using long-exposure or composite images, time can be represented in unique, beautiful ways. The artistic restriction of painting led to Pablo Picasso pioneering cubism, which attempts to represent the many faces of a three-dimensional object on a two-dimensional medium. Great literature can be produced from limitation also, such as haikus or flash fiction, such as the infamous six-word story by Ernest Hemingway: “For sale: baby shoes, never worn”.
There are many reasons why designing under constraint results in greater works.
Firstly, choice and freedom can be paralysing. When we have absolutely no restricitons, rules or guidance, we have difficulty processing the sheer number of possibilities, because there are too many things to consider. We find it much easier to make a decision and proceed when there are a limited number of choices.
Secondly, constraint often comes in the form of consistency. One of the basic rules of graphic design is to limit your colour palette and font types to avoid clutter and messy design. A consistent theme is much more aesthetically pleasing. This is a core principle of minimalism.
Lastly, limitations encourage creativity as the designer has to come up with a way to overcome the restriction only with the available resources.
A fine example is Gothic churches. It was very difficult putting in large windows in church walls as they would cause structural instability. So architects devised flying buttresses to help bear the load. But even then, the technology for building large, transparent glass windows had not been developed. So instead, they pieced together small, coloured glass pieces to make stained glass windows, introducing light in to the church while telling stories from the Bible.
Ironically, limits and restrictions can be the catalyst for something better. Instead of rebelling and fighting against constraint, try adapting and coming up with a creative way to overcome it.
Legend tells the tale of the Gordian Knot, a knot tied so tightly that it seemed impossible to undo it. The Phrygians’ oracle even prophesised that the person who untied the knot would become the ruler of all of Asia Minor. Many tried to loosen the knot, but the knot remained secure for years.
In fourth century BC, Alexander the Great came to the city amidst his business of conquering everything around him. Of course, he could not pass the challenge by, so he too attempted to unravel the Gordian Knot. But alas, not even the great Alexander could untie it.
He then took a step back and thought to himself that it did not matter how the knot was undone. So he took his sword and sliced the knot in half, much to the shock of his audience. As the oracle prophesised, Alexander ruled the great Macedon Empire, stretching its border past Asia Minor, almost reaching present day China and India.
The story of the Gordian Knot teaches the importance of thinking outside the box. We can tackle a problem again and again without fruition if we try only one method. Just when you start to feel frustrated, take a step back and consider a different approach.
Another lesson is the value of combining two different fields. Instead of using typical knot-untying skills, Alexander chose to use military skills. Many innovations have arisen from borrowing skills and ideas from different fields – known as cross industry innovation.
For example, instead of complicated controller designs for drones, the US Army found using an Xbox 360 controller was far more effective. Computer models simulate the way ants find optimum paths to solve complex mathematical problems such as the Travelling Salesman Problem. The combination of waffles and shoes resulted in the creation of waffle rubber soles to increase traction in running shoes. Many engineering feats borrow ideas from nature, such as the aerodynamic design of planes and structural strength of arches and curves as observed by Gaudi.
In graphic design, placeholders are very useful as it allows you to design a template, then substitute in the appropriate material, such as photos, when the design is finished.
This is particulary useful when designing the overall layout, as you can play with the spacing between items, how big the image should be, et cetera.
The same is true for text, but it is not as simple as you would imagine.
You could paste in a block of text that is an excerpt from somewhere, but this comes with the issue that it is distracting. This is because we are hardwired to start reading a line of text to understand it. Therefore, the designer is distracted from seeing the overall layout as they see the trees instead of the forest.
You could type gibberish text, but this does not look aesthetically pleasing at all.,
An elegant solution is the Lorem Ipsum text. Lorem Ipsum has been used in the printing industry since the 1500s. Ever since, it has been the gold standard in printing and design, both analogue and digital.
As an English speaker, Lorem Ipsum almost looks like normal text, but on closer inspection, you soon realise that you have no idea what it says. However, it is not complete nonsense – it is in fact a collage of text taken from a piece of classical Latin literature called “de Finibus Bonorum et Malorum” (The Extremes of Good and Evil) by Cicero, written in 45 BC.
The standard Lorem Ipsum passage that the industry still uses to this day is largely unchanged since the 1500s. It goes as follows:
“Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.”
We look around the world we live in and marvel in all its complexity and grandeur. But Mother Nature focusses on one thing when it comes to design: efficiency. That is to say, that nature strives to design things that will do the job best. For example, stars and planets are always round because a sphere is the most effective way to get all the mass as close to the planet’s centre of gravity as possible (a process known as isostatic adjustment). The wings of a bird have evolved to maximise the thrust generated at the least energy cost, while the sleek, teardrop body shape of fish allow for them to slip through water with minimal resistance. One of the best examples of nature coming up with the best design solution is beehives.
If you look closely at a beehive, you will find that it is made up of tiny hexagons. Each hexagon is a room that a bee can fit in and the walls are made from wax. The interesting thing about hexagons is that it has many properties that make it the ideal shape in construction.
Firstly, hexagons can fit together perfectly to tile a plane, meaning that bees can tile thousands of columns without wasting any space. The little columns even end in a unique pyramidal shape that allows them to tile up nicely with each other at the centre.
Secondly, a hexagon has 6 rotational symmetries and 6 reflection symmetries, making it very easy to tile as every bee will know what orientation to build their cell in using the side of any cell as a reference.
Lastly, in a hexagonal grid each line is as short as it can possibly be when tiling an area with the smallest number of hexagons. Therefore, bees can use much less wax when constructing hives, while achieving remarkable strength as hexagons gain lots of strength under compression. This design also allows for the maximum amount of honey stored in each cell.
Bees have mastered this architectural feat not through physics and mathematics, but through evolution – the driving force of nature. Over millions and millions of years, various types of bees will have experimented with square-celled hives or triangular-celled hives, but they could not survive as long as the hexagonal-celled bees because their hives were less efficient. This is exactly why nature is so good at coming up with the best solution to a problem. Because in nature, the best solution to the problem an environment offers is rewarded with survival.
Red, green, blue, white… There are many colours that we can see and there are even more different combinations of colours possible. It is common knowledge that some colours clash with each other while some synergise very well. A common example of a “good combination” is when you use complementary colours. Complementary colours are two colours that oppose each other on the colour wheel, creating an effect where they brighten each other. This makes it very eye-catching and attracts people’s attention. For example, blue and orange make a bright contrast making them a popular colour choice for movie posters. Red and green, and yellow and purple are also examples of complementary colours. Complementary colours are an important concept in art and design as it helps the product stand out.
Complementary colours have an interesting relationship with our sense of sight. If you stare at a colour for a while then quickly look at a blank, white surface, you will see an afterimage of the complementary colour. A good example is when you have your eyes closed under bright sunshine and upon opening your eyes the world seems a blue hue (the blood vessels in your eyelid make the light appear orange as it reaches your eyes). This is because the retinas try to negate the intense colour by downregulating the nervous signals corresponding to that colour, which makes the complementary colour stand out. Furthermore, the photoreceptors in the retina become fatigued after stimulation, causing a reduction in the signals sent for that colour.
Knowing about complementary colours is very useful when designing a sign or poster that easily attracts people.
