FBS ANALYSIS

Function-Behaviour-Structure ontology

It is a framework for conceptualizing design of objects in three categories: Function, Behaviour and

Structure. It is used to represent objects.

These categories are defined as follows:

Function (F): It is the purpose or the end objective of an object.

Behaviour (B): The attributes that can be derived from the object’s structure.

Structure (S): The components the object comprises and their relationships.

The Function-Behaviour-Structure Framework

The original version of the FBS framework was published by John S. Gero in 1990. It applies the FBS

ontology to the process of designing, by further articulating the three ontological categories. In this

articulation, behaviour (B) is specialised into expected behaviour (Be) (the "desired" behaviour) and

behaviour derived from structure (Bs) (the "actual" behaviour). In addition, two further notions are

introduced on top of the existing ontological categories: requirements (R) that represent intentions from the

client that come from outside the designer, and description (D) that represents a depiction of the design

created by the designer. Based on these articulations, the FBS framework proposes eight processes claimed

as fundamental in designing, specifically:

1. Formulation: formulates the problem space, by transforming requirements into a function state space (R → F), and transforming functions into a behaviour state space (F → Be).

2. Synthesis: generates structure based on expectations of the behaviour state space (Be → S).

3. Analysis: derives behaviour from the generated structure (S → Bs).

4. Evaluation: compares expected behaviour with the behaviour derived from structure (Be ↔ Bs).

5. Documentation: produces descriptions of the design based on structure (S → D).

6. Reformulation type 1: modifies the structure state space, based on a re-interpretation of structure (S → S’).

7. Reformulation type 2: modifies the behaviour state space, based on a re-interpretation of structure (S → Be’).

8. Reformulation type 3: modifies the function state space, based on a re-interpretation of structure and subsequent reformulation of expected behaviour (S → F’ via Be).

NON – FUNCTIONAL HATS:

In this hat, even though the crown is normal the brim is extended

downwards so much that it covers human eyes, which makes it

non-functional.

Here brim is placed inside the hat without changing the crown. This does not

allow head to get inside which makes it non-functional.

In this hat, the crown’s width is extended than normal. Now, as the brim starts

off much farer from head’s position it could not provide any kind of grip. This

leads to its non-functioning.

Here, the hat is made of transparent and soft material. So, it does not protect our

head from sun and rain making it non-functional.

Here the crown’s base circumference is 25cms only.

Whereas the average circumference of adult’s human

head is 53cms in females and 57cms in males. So, head

cannot fit into this and thus making it a non-functional

hat.

Design a hat with an added function

Additional Function – Earmuff

Hat is also going to serve as an earmuff protecting ears. Fits on the

top of the head and covers external ears with thermoplastic band.

Made of fur to keep person’s ears warm in cold environments. An

elastic string is added to keep earmuffs closer to our ears.

Creative design of hat

Horns are added to the crown and brim is removed. Horns

can depict a particular animal which provides fun element.

Design of the hat can vary depending on the position and

shape of horns. Can be worn while celebrating or attending

parties. Allows to produce wide range of horn shapes.

Hat with an added adjective

Adjective – Status/ Identity

Change in the length of the conical crown. Different

sizes for different class of people in a society. A Kind

of uniform/customary dress code.

Long – Authority

Medium – Middle Class

Short – Low Class

Vladimir Propp

Vladimir Propp was a Soviet folklorist and scholar who analysed the basic plot components of Russian folk tales to identify their simplest irreducible narrative elements.

He concluded that all the characters could be resolved into 7 broad character functions in the 100 tales he analysed:

1. The hero—Leads the Narrative and is usually looking to solve a problem. Reacts to the donor, weds the

princess.

2. The villain — Conflicts Hero/Struggles against the hero.

3. The dispatcher — character who makes the lack known and sends the hero off.

4. The (magical) helper — helps the hero in their quest. Often acts as a sidekick.

5. The princess or prize and her father — the hero deserves her throughout the story but is unable to marry

her because of an unfair evil, usually because of the villain. The hero's journey is often ended when he

marries the princess, thereby beating the villain.

6. The donor — prepares the hero or gives the hero some magical object.

7. The false hero — takes credit for the hero’s actions or tries to marry the princess.

He also concluded that there are a sequence of 31 functions that usually occur within fairy tales, once the initial situation is depicted.

The Road to El Dorado

The Road to El Dorado is a 2000 American animated adventure comedy film

The movie begins in 16th-century Seville, Spain, and tells about two men named Tulio and Miguel. During a dice game using loaded dice, they win a map that supposedly shows the location of El Dorado, the legendary city of gold in the New World. However, their cheating is soon discovered and as a result, they end up as stowaways on Hernan Cortes fleet to conquer Mexico. They are discovered, but manage to escape in a boat with Cortés' prize war horse and eventually discover the hidden city of El Dorado, where they are mistaken for gods.

Analyzing with Propp’s 7 characters

1. Hero – Tulio and Miguel 2. Villain – Hernan Cortes 3. Dispatcher – Miguel 4. Helper – Altivo(Horse) 5. Prize - Chel Authority – Chief Tannnabok 6. Donor – Zaragoza, Chel, Chief Tannabok 7. False hero – Tzekel Kan

NARRATIVE STRUCTURE

Hero – Tulio and Miguel

Tulio and Miguel lead the play. They are good friends. They win a map to the City of Gold, El Dorado, in a gambling match. Somehow they reach the city with a horse, Altivo. The movie is all about their attempts to survive in the new city and to bring back some gold to Spain.

Villain – Hernan Cortes

Hernan Cortes is conqueror. His appearance in the movie is less. He tries to conquer El Dorado city with the help of Tzekal Kan

Dispatcher – Miguel

Miguel, one of the friends acts as dispatcher. He plants the desire of reaching the city of gold and bring back some. Then they built their own assumptions on the city.

Helper – Altivo (Horse)

Altivo helps them in reaching the city. It stays in the city and returns back

with them and witnesses all the adventures that take place.

Prize – Chel

Chel becomes the prize for Tulio. Initially she is need of help from these friends but finally becomes prize for Tulio.

Authority – Chief Tannnabok

Chief Tannabok is the authority in the city El Dorado. His orders were followed by the people of the city.

Donor – Zaragoza, Chel, Chief Tannabok

At different situations different donors are found. Even though the win the map fairly from Zaragoza, he can be classified as a donor of the map. Chel for donating an armadillo (Biblo) for ball in the ball game with the best players conducted by Tzekel Kan. Chief Tannabok for donating ship.

False hero – Tzekel Kan

Tzekel Kan tries to take the credit everywhere. When he came to know that Tulio and Miguel are not gods, he tries to become the god in front of people.

Tzvetan Todorov

Tzvetan Todorov is a Franco-Bulgarian historian, philosopher, literary critic, sociologist and essayist. He is the author

of many books and essays, which has a significant influence in anthropology, sociology, semiotics, literary theory,

thought history and culture theory.

He concluded that there are 5 fundamental stages in any kind of narrative

1. Stage of Equilibrium 2. Disruption of that order by an event 3. A recognition that disorder has occurred 4. An attempt to repair the damage of disruption 5. A return/ restoration of a new equilibrium

TIMELINE

This is the timeline analyzed for these stages in the movie. Even though there are multiple layers/ levels of story leading to overlapping of stages and disorder, the overall timeline is analyzed as follows

1. 0 min – 8 min (Duration: 8 minutes)

They stay in their city in their own lifestyle. They play gambling in their city in Spain.

2. 9 min – 21 min (Duration: 12 minutes)

Then they try to travel to the City of Gold, El Dorado.

3. 22 min – 28 min (Duration: 6 minutes)

Then they understand that, it is not that easy to reach this city and start getting into troubles one by one and realize that.

4. 29 min – 1hr15 min (Duration: 46 minutes)

Here they try to overcome these troubles be acting as gods get into new troubles and attempts to solve them.

5. 1hr 16 min – 1hr 23 min (Duration: 8 minutes)

Now they come out from the city after an adventure. Even though they could not bring back any gold they save

the city from Hernan Cortes.
