The company Polirtlak d.o.o. is specialized in manufacture of concrete floor grinding machines. They approached us with the desire to transform their existing line of grinding and polishing machines Linolit. They wanted to redesign of their existing machines and to make differentiation of product on the market of polishing machines. We were faced with the challenge – to create a unified line of three grinding machines, in spite of their various sizes and minor differences in structure and at the same time keeping them in the lower price range.
We began the design process with a detailed analysis of the machines (their constituent elements, function, user interaction) and extensive market research. The main conclusion was, that apart from the unique purple colour, Linolit does not differ greatly from the other manufacturers.
When designing this machines, special attention was given to two main elements – the main construction and the metal box.
Our studies of geometry are based on our initial sketches and the introduction of these elements are incorporated into polishing machines. The existing technology of producing the basic structure from steel profiles did not allow major design changes, what led us to change the manufacture process. With the introduction of laser cutting of sheet metal we were able to give the main structure any desired shape. This change simplified and accelerated the production and in addition reduced the amount of needed manual work, thus reducing the deviation and errors in manufacturing process.
The housing is the most visible element of the machine. By changing it, we wanted to differentiate Linolit from the competition and at the same time give the appearance of robustness, professionalism and highlight the engineering quality and the quality of manufacture. Straight, sharp lines of the basic structure were transferred on the metal casing and the design language was passed on to all three machines to unify them despite minor differences.
As the result, a new generation of grinding and polishing Linolit machines was formed, characterized by their though-through geometry and unified design language.
