Being creative can be complicated when it is tailored for the masses. It is a multi-variable equation in need for an optimum solution and that is exactly the reason I love being an industrial designer. I like to mix all different types of bits and pieces from research methods and design models to testing prototypes and optimizing the available manufacturing procedures. These actions are performed in an ever changing environment which requires structured thinking and quick decision making so that existing boundaries will be expanded and an optimum solution could be achieved. Solving the equation is the greatest reward and my own personal way for shaping a better tomorrow.

“I like having a relaxed life pace”
“A product is the reflection of the interaction people have with it”. This quote concentrates the philosophy of the Vision In Product design model which was used for the needs of this project. The ViP model is used when working with a future scenario while having as an information base an existing scenario, existing products and interactions. It consists of two phases, the deconstruction phase and the designing phase. During the first phase, research regarding the above mentioned factors is performed so that a future context can be shaped. With the help of the future context the desired future product interactions will be defined and help putting forth a suitable product concept.

Ease of use
The future pedelec eZin is a pedelec which offers intuitive riding right from the very start. The rider maintains constant grip on the steering even while braking or signaling a turn. Buttons activate turn signal lights situated on both handlebar ends and rear bike rack offering 360 visibility. The nitification bell besides a bistinct sound provides visual warnings to the traffic environment. Proximity sensors can notify the rider for cyclists or vehicles being in the riders blind spot. These features aid the rider to be fully aware of the traffic situation. A similar feature set improves the bicycleâ€™s ease of use. Back pedaling acitvates a hydraulic ABS system for efficient and effortless braking. The in-frame motor can be regulated according to the riders vital sign so physical stress is kept minimized. Directional speakers integrated inside the handlebar provide audio information to the rider without blocking external traffic sounds. The saddle helps the rider maintain good blance by self adjusting itâ€™s height according to the riding speed. With all the added features eZin has the potential to present an interesting biking solution to all riders.
Design 360o Indicators and turn signals Front and rear lights as well as the turn indicators integrated in the handlebar provide complete information regardless the situation and the viewing angle.
Vibrating notifications A variety of notifications can be passed through vibrations which are emitted inside the handlebar to help the rider understand better the traffic situation (eg. a bicycle is overtaking from right)
Directional speakers Integrated within the handlebar the two speakers provide quality sound for a variety of different uses directly to the rider without losing contact with the surrounding environmental sounds.
Multi sensory bike bell Combining two different sensor modalities the bike’s bell maximizes efficiency by activating simultaneously both the front light and the integrated notification horn .
Combined Anti lock Breaking System (ABS)
Breaking is activated and regulated by backpedaling. The internal hydraulic system drives both the front and rear disc brakes and eliminates wheel blocking. Optimal breaking is achieved.
Vital signs adjusted assistance Optimal physical exercise can be achieved. The motor’s level of assistance can be regulated according to the riders vital signs. It is best used for rehabilitation and normalized exercising causes.
Proximity sensors An feature which aids the rider’s situational awareness especially in relation to the “blind” spot and overtaking cyclists.
Today’s belt equipped drive systems successfully offer low maintenance, clean, quite and reliable commuting, characteristics which are favorable to the targeted market.
Reduced crank length Shorter crank length can result in a lower bottom bracket and therefore a lower center of gravity. In addition, leg movement is minimized providing great comfort for riders with mobility issues.
Self adjusting saddle Taking advantage the bike’s hydraulic system the seat post can be automatically regulated in height in occasions where stability is essential like for example reaching a full halt.

HAND SAW EFFICIENCY MEETS PRECISION
Beyond handsaws... FLEXIBILITY
The project is focused in the benefits of manual handsaws and ways to implement those in the product design. The later years power tool domination is driving manual driven products to extinction. In order to sustain and develop their market share a different approach need to be implemented. To be able to find the needed information extensive user studies were performed together with a broad market research. User studies are not only focused in manual saw users themselves but also in the retailers and manufacturers. The projectâ€™s final result is a range of three different manual pull saw products with an innovative set of features towards function and user interaction. Extensive effort is given so that the product range has a strong connection with the brand through appropriate product quality and form language.
The study’s aim was to map the usage of manual saws and find unexplored areas in the market. Different user types were examined in relation with various factors so that a holistic context view could be created.

SAWS Completing several braiwriting sessions resulted in a vast amount of ideas and forms to work with. Evaluations with user groups were performed. New ideas and new designs came into play from which the three final designs were chosen.
Beyond handsaws... Based on evaluation, the most interesting part of the concepting phase was the pull technique. It is considered to have great potential to expand it to new usage areas and therefore it was selected to further develop a range of three pull saws including the high precision saw, power pull saw and pocket saw. Providing a range of saws besides being favorable from the actual users it will be easier to introduce to retailers. The three pull saws are intended for different purposes and situations. The first is focused in usage were high precision is required, the second is characterized by high efficiency and the third one is targeted towards occasions were increased accessibility is needed. All three concepts have advantages when compared to electric saws just as well as to other manual saws that use the push technique.
Features Pulling technique
A normal saw is pushed against the working piece in order to cut, an action which introduces compression forces to the blade. Buckling is often evident and so, pushing saw blades need to be thick to prevent it. On the other hand a pulling saw cuts while pulled away from the cutting piece which introduces tension forces to the cutting blade. Tension forces are desirable because the blade remains straight without being thick. With less blade width the resulting cuts are created easier with better quality
Extensive focus was given into the size of the different saw types. Blade length and height size, handle size and overall size were taken into account. Decisions were much dependent on the type of cuts every saw was intended for and also the visual expression the saws were required to have. For example a long handle inspires more confidence making precision cuts. The foldable saw was the one with the highest dimensional interest due to the demand for increased mobility.
Retractable blade support
Having a high reflective blade surface brings an interesting interaction between the actual cut and the user. Not only before but also while cutting in the beginning of the cut, the user can make sure that the blade is orthogonal to the cutting surface by looking the workpiece's reflection in the blade. If the reflection is aligned with its own edge then the saw blade is perfectly positioned for a perpendicular cut. An easy and straightforward way to improve cutting.
Precision cuts with a pull saw can be further improved by the use of a rigid blade support. Instead of having two different saw types, the support can be retractable to enable having the benefits of two different pull saw types into one. Flush surface cuts and even slight curved cuts can be performed without sacrificing high precision. The feature is simple to implement and straight forward in itâ€™s use. The back support is completely encased in the handle when not in use.
For use in situations where fast and efficient cuts are needed. It incorporates an open handle to express the pulling function with typical 45o and 60o markings. It’s blade is thiner, longer and higher than normal push saws with fine teeth especially closer to the handle to aid the cut’s starting movement.
Used for precise cuts that can only be executed by a pulling handsaw. It’s extra thin blade comes with a retractable blade support to aid the accuracy of the cut in certain occasions. 200mm Long handle inspires confidence and can be used with both hands.
Focused in the users need for high flexibility in usage. Because of its size it can easily fit into a working pants folding rule pocket. Therefore it is always available and can be used for small cuts that can occur unexpectedly. Blade has 3 locking positions open closed and 45o.

Lights the way
This project is focused on targeting specific market groups by offering products with certain expression and corresponding qualities. The market area were the focus is set is related with interior office spaces. In addition, the starting requirement is to offer a complete lighting solution by bringing to life a family of luminaires which consists out of a working, an ambient and a secondary luminaire. After completing a thorough research towards the desired product qualities the resulting product family is ready for production. â€œFrankâ€? luminaire set brings besides innovative features an appropriate expression for the specified application.
Explore & interpret
Persona & Product expression
An extensive market research was performed to familiarize with the current light forms, materials and the corresponding manufacturing methods. The resulting six categories express specific types of forms due to the nature of the respective material and the forming capabilities that it provides. These categories were further sorted into different types of manufacturing processes for each material.
In order to create a persona that will reflect the targeted market group expression a series of steps were taken. A formal board was created to define the desired product characteristics and create a theme which in turn will help shape the persona. In the next step the persona will be used as a tool to provide formal drivers for the actual luminaires.
Fabric Various form types and shapes. Usually it is combined with rigid and light structural frames to provide the desired shapes.
Formal Starting Board
FIRM, HIGH QUALITY
UNIFIED, CLEAR, OPEN SYMMETRIC, DISTINCT, BASIC
SLIM, SUFFICIENT CLEAN, CONTRAST
Paper All types of forms. The production methods used include, among many others, folding, stamping and cutting.
Glass Mainly, simple organic forms. Production is achieved by using blowing glass techniques.
Plastic All type of luminaire forms. Wide range of industrial processes like injection molding, vacuum and pressure forming.
Metal sheet Relatively broad range of forms. Production is performed by a wide range of processes.
Ceramic Mainly it provides organic forms. Production methods include shell & slip, casting and hand building.
Realizing A series of ideation and sketching sessions resulted in designs which were evaluated according to the previously defined criteria. The designs were refined in order to enhance the features of the products as a luminaire set. In addition, details and adjustments were decided towards manufacturing processes, final materials and finishes. All the above were also filtered through the corresponding costs and targeted price range just as well with sustainability issues. Physical models were constructed to verify the design intention and examine lighting issues regarding light glare. The model also offered the ability to observe interactions of the luminaire frame with the light source and enhance them.
for an office interior... The light sets given name “Frank” is derived from the essence of its’ favorable expressions. Frank(adj) - direct; straightforward; sincere
Evaluating A survey was held to confirm the initial design intention. Quantitative and qualitative questionnaires were given to 20 participants from the targeted market group. The participants were asked among others to characterize the expression of luminaire set. The results were encouraging but also showed some room for improvement. Several people commented that the individual luminaire features linking to a luminaire set were inadequate and therefore few final design tweaks were performed.
Distinct Straight forward
Despite thought the fact that the project was focused on the product expression, considerable effort was put into other aspects like defining manufacturing details, sustainability and environmental issues and cost related issues. These aspects are not directly connected to the product’s form expression but they complete the product as a whole and therefore is necessary to address them. It is the expression and the function of the product that will make it desirable to the specified market group and the rest of the factors the ones that will determine the extend of its’ market success.
