Cone-Shaped coffee filter.

Manufacturing Process:

Coffee filters are made from crepe papers which are produced in paper machine which has a large steamheated drying cylinder that is fitted with a hot-air hood. The cylinder is then sprayed with adhesives to stick the crepe panels together to form the coffee filter.


The creped panel of the coffee filter together with its cone like shape allow the coffee to have a smoother flow from the funnel to the coffee pot. Flattened Plan View

Reading reflection: 130mm

The book describes and educates design through a historic perception and emphasizes the need to regard design as a process which not only manufactures products but also educates us about how needs, activities, form and use, technique and material all take equal parts in industrial design.



This coffee filter illustrates such an ideal as the design is not modern but its simplicity and elegance in performing its tast prevented its elimination through the years. (albeit the shapes of the coffee filter varies accordingly)

Measured Drawings

The filter is first measured when it is completely flat to understand it’s basic dimensions. The filter is then pushed open into it’s functional position. The new length of the filter is remeasured and using pythagoras theorem, the triangles produced by the theorem allows me to measure the different heights from the mid-point of the filter.

Axis of connection

Properties of the model:

The panels of the coffee filter is illustrated in these screengrabs to be along a single axis. Due to the nature of the material, the panelling structure is not solid but instead flaps around with regards to the environment.

Attempt at modelling:

Generally I believe I was able to illustrate the basic shape of the coffee filter and at the same time able to show it’s randomness when it’s flap is open. However the stitches at the ends of the panels could be modelled in to improve on the overall feel of the coffee filter.

Panelling Mechanism

Coffee filters are constructed by gluing them along the punctured areas, joining different panels together. To make use of this method, there is a need to dissect the properties in which a coffee filter has. Ultimately the design of the coffee filter is one which is extremely simple. Two identical panels are fixed together at three points to retain it’s shape and at the same time have the flexibility to create a funnel - a small end compared to a large opening.

Connecting Axes


I feel that it is important to stay true to the original object’s properties and thus I attempted to reduce the complexity of my design as much as possible. The coffee filter occupies space in a way such that there is a contrast between the top (able to occupy more volume) and the bottom (able to occupy less volume). I show case this in my scale models and as visible, there is a similar funnel like structure in the model. The material was chosen to be paper as it retains the flimsy and flexible capabilities of the coffee filter. The construction of the model is done using the coffee filter’s mechanism in which the ends of each panel are connected via adhesives.

Model Interior

The interior of the model is chosen to be darker to reflect the aftermath of coffee filtration and at the same time gives contrast with regards to its exterior.

The Turtle

Sommer describes personal space as an area of comfort which changes depending on the circumstances that surrounds the individual. He also describes how personal space is different for different individuals. In general extroverts tend to be more comfortable being closer to another individual as compared to introverts. This design elaborates on the shielding of an individual - much like that of a turtle’s shell. The shield covers the most ‘vulnerable’ parts of the individual, the front and the back, and is designed via large, flat panels - much like that of a turtle’s shell. This design illustrates the fear of social contact and the design attempts to aid the individual in distancing him or her away from unwanted contact. Making use of the folding and connection mechanism of the coffee filter, the shell will be linked together as a whole piece. The design could also be flexible and perhaps even flimsy similar to the filter, to illustrate an organic impression - second skin being part of the user.

The Pincer

Amy Cuddy describes powerful people as people who are confident, people who aren’t hesitant to take up space and perhaps in some cases, invade another’s personal space. Personal space in this case is being invaded. The pincer presents the desire to step out of the comfort zone - to conquer - to overpower. The design attempts to illustrate a panelling style but in contrast to the turtle design, the panels are not only smaller and sharper, they are also inverted to occupy as much surface area as possible. The design is positioned on extremities as the user is unafraid and thus needed no protection. Instead the design attempts to enlarge his own space and may potentially invade others’. This design is similar to that of the coffee filter’s fold and connect mechanism but is inverted to exploit more surfaces. Same organic ideal as first design could be considered.

The Lock

Personal space need not be a spatial concept. I believe privacy is an essential part of personal space in which most people appreciates. However with technological advancements and our increasingly complex networks and smartphones, privacy seems to be diminishing by the years. Long gone are the days where weekends or nights are as comfortable as you want them to be due to the difficulty, as compared to today, in contact. Modern life is always accompanied by emails, messages wherever one goes and sometimes it may get as suffocating as spatial invasions. With the growth of large social and data companies, much of our information are not our own anymore. This design attempts to symbolise that by illustrating that perhaps the only place of solitude left in our lives today are that in our minds. The panels cover the head of the user and much like that of the turtle shell, the panels are flat and protective. Same concepts as the first design in terms of panelling mechanism.
