Libra Scale

Context Thinking about kitchen scales is remembering the pleasure of cooking. In this changing world more and more people choose pre-made, prepared or instant food instead of using receipts. Cooking is seen as a great pleasure by some people, though the kitchen environment is not prepared yet to be the new living room in the contemporary house, where people divide their time between meals, entertainment and work.


The Kitchen as the new Living Room Living rooms were meant to make us feel good. Everything seams to invite us to relax, to forget the routine. Kitchens, in the other hand are usually a house attachment, a room of minor importance, a place filled with appliances, tools, all sort of machines and the so common fluorescent lamps. So the challenge I set for my self was to build a kitchen scale that could bring the living room feeling to the kitchen environment. An aesthetically pleasant object that could transform the act of cooking into a delightful ritual.


Libra Scale

The Challenge, The Concept The challenge I set for my self was to design a kitchen scale that could bring the living room feeling to the kitchen environment. An aesthetically pleasant object that could transform the act of cooking into a delightful ritual. For so, it seam pretty clear to me that an analogical system would suit the best my concept. Then, the idea of using elastic springs and a retractile ruler came along. That system would allow the scale to be quite hygienic and precise, yet elegant and good to look. Cooking for one is indeed cooking for you. A chance to be creative, a moment to think about yourself and not about your work. A good meal is in fact a great present for your body and soul after an exhausting working day. One ruler, one dish, one bowl, two springs and a metal frame, that's what I purpose for someone who wants to enjoy the moment of cooking as a pause. An object that invites you ,through it's presence, to plan your meal, to weight the ingredients, to treat yourself right. A kitchen scale that communicates in silence, that reminds you how pleasant cooking can be.


Libra Scale

How it works The spring principle is a common system use for weighting. Also know ans newton method, it measures the weight through distance. Once the spring stretches with the weight of the object, its length expands in proportion. Libra is based on this very principle. With 2 elastic springs, one plate and one retractable ruler, it allows you to weight quickly and quite accurately. The range of weights supported by the scale vary between 75 gm and 500 gm, once it was thought for one person. There is no risk that the springs may brake once the surface where the scale stands is the limit for stretching The retractable ruler displays the weight being measured right on top of the structure, graphically. It’s system retracting makes it possible that there is always tension and that the ruler stays aligned perfectly. The weight of the plate guarantees that it is horizontal and in tension even if it is not being used, while the 2 springs hold it on 4 points to enhance stability. The design of the metal structure makes it sure that the scale stays still and standing due to its concentration of weight of the bottom massive bar.

Start at 0 - with or without bowl When do you want to weight some ingredient you can choose if you want to use the plate or the bowl. Both options are possible with the same ruler since you can extend it and retract it using the two screws to fix the ruler. The distance between the 2 screws was thought to anulate the extra weight of the bowl. A small engraving of the bowl is situated by the screw, so that is easy to understand which one to choose.

Retractable Ruler The retractable ruler is the element that translates the weight into carateres. Its system relies on a mechanism that guarantees that the ruler is always in tension. The ruler it self only shows the value that is being weight. The other numbers rest on the back part of the ruler that is not displayed directly to the user. The system is fully integrated into the metal structure and it’s seamless when observed by naked eye.

One bowl, One plate - the right measure for you Libra was designed to fit a single person needs. Both the bowl and he plate are dimensioned to satisfy the user common needs. Therefore the containers may carry liquid, grainy and solid ingredients. The bowl may contain up to 1/3 L and the plate counts with a quite large surface to put big ingredients. Both solutions might be detached from the main structure, so that you can clean them after usage.

Libra, the user and the kitchen Libra was designed for the kitchen as the new living room. So it’s shape, materials and size, work together for inviting us to use it. It was meant to be a scale that reminds you to treat your self right, to relax your mind and give your body a good meal and, even better, a pleasant cooking time. Therefore its shape is notorious within the kitchen scenario. Its strange contours captivate our attention and invite us to start the ritual of cooking. The weighting system, the cosy feeling provided by the wood containers, the elegant and discreet structure and the colourful springs appeal to the user from the kitchen balcony. Its size fits you and the soften edges and the hygienic finishes guarantee a safe and comfortable usage.
