It is all about fixing...First steps KLIPS I ntroduc tion KLIPS is a clamp for hanging rigid panels or banners. It’s easy to install without making holes into the material. As well it’s can be widely used for outdoor fixing. KLIPS is suitable for different types of material as: heavy textile, panels, glass. There is a growing need for easily handling room dividers.
Work with the companyR-FIX is involved in production and sales of glassfittings, tension rod systems and other architectural Point Fixingfixings. Concerning materials they use mainly stainless steel but also various plastics, aluminum and otherTheir fixings have been used in: steel grades. They buy raw material from known• Glass balustrades, stair boundaries European suppliers.• Glass facades• Glass canopies R-FIX helps you to carry out your construction• Glass partition walls projects in offering cost effective and high-quality• French canopies architectural fixings.• Noise barrier wallsIn product development process they use 3Ddesign software and carry out strength calculationsor tests according to your requirements. They offerstandardized fittings as well as fittings according tothe project requirements.Production capabilitiesIn our production they use:• CNC-turning and CNC-milling• laser cutting• bending• welding

Find new nische for the companyOur work we started with company visit, which And the line of products it’s not so unique, so theis situated a bit outside of Tallinn. We were on one way for them it’s to find new direction with theproduction aria and people who work there new ideas.

KLIPS R esearchResearching the “WORLD OF FIXINGS”Before going to company visit we made smallresearch and found all the fixings that existed andall the areas we could work on.Surprisingly we found very wide choice of everykind of fixings beginning from glass fixing forfacades to the stainless still fixings for stair rails. We have overviewed modern architecture, finding and understanding new trends and demands. Also had consultation with architects asking them: What is missing in”afixing world” and what can be improved?Our focus were::Architecture – Provide smart solution for facades.Wooden Architecture – Focusing on existingproblem of wooden buildings.Boats – There are lots of stainless still details whichcould be redesigned or reinvented.
Deeper research of some fieldsWe made comparison matrix to understand which materials, functions and production methodswe preferred.

KLIPS R esearch“KLIPS” is a clamp for hangingrigid panels or banners. Our selling point hasIt’s easy to install withoutmaking holes into the material. to be “EASY”. After introductory weeks while we explored every field where we could develop or invent a fixing we defined few interesting spheres and continued searching for the solution. We had few ideas which seemed to be interesting to work on. To decide what direction we choose we met Priit Kello once again and presented fiends in which we could develop the product. We found lots of ideas and few of them were developed. After that market research took place and finding weaknesses in our solutions. Ideating process gave us complete view on existing products. We found main idea how to develop product for R-fix.
Inspiration WorkshopInterior design office Owr next step was decision to make a work shopall together with our group and brain storm ideas,as a place for it we choose one interior design office,which had very appropriate atmosphere for it. The work space was quite big and was good idea to divide the room on two parts by putting onBecause there were so much details in decoration the middle of the room carton. That was heavyof the work space, mostly previous projects. material, which could give the feeling of two rooms.That was rather interesting to look around and try Looking on that carton in the office andto think about each project may be it has thinking about material fixing we came with thesomething in common with our work. idea that we need to create something whichhere was definitely a lot of fixing of different would hold the material in a way not damaging itmaterials. by stamping.

KLIPS R esearch Nevertheless there are the tools, that can hold a very big weights without damaging the material.Research: Different clamps and brackets Usually simple clamps are not strong enough to hold heavy materials After making research on material fixings we set a goal: “To combine the grab mechanism with the slid- ing track.”
Process Track roller Simple curtain track roller is not strong enough to hold big weights Heavier weight requires stronger track system The idea is to use a standard track roller fitting However, how to fix the panels? What kind of clamp mechanism to prefere?
