KLIPSFirst steps

I ntroduc t ion

It is all about fixing...

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 company

R-FIX is involved in production and sales of glass

fittings, tension rod systems and other architectural

fixings.

Their fixings have been used in:

• Glassbalustrades,stairboundaries

• Glassfacades

• Glasscanopies

• Glasspartitionwalls

• Frenchcanopies

• Noisebarrierwalls

In product development process they use 3D

design software and carry out strength calculations

or tests according to your requirements. They offer

standardized fittings as well as fittings according to

the project requirements.

Production capabilities

In our production they use:

• CNC-turningandCNC-milling

• lasercutting

• bending

• welding

Point Fixing

Concerning materials they use mainly stainless

steel but also various plastics, aluminum and other

steel grades. They buy raw material from known

European suppliers.

R-FIX helps you to carry out your construction

projects in offering cost effective and high-quality

architectural fixings.

Task

Research in architecture: screens, interior and

exterior walls, light structures, new materials …

Concept

•definingdevelopmentdirections

•conceptsketchesDevelopment

Our task was to find new directions for development

of Radius Fixings in order to offer new possibilities

and solutions in contemporary architecture.

With the background in glass fixings R-Fix wants

to look further and find possibilities to use the

knowledge and skills learnt in other areas, with

other possible materials and technologies.

“I am really glad that had opportunity to work in cooperation with the company. And I am happy with the result which we got out of it.”

“I like the meetings of brainstorming. The result is always unpredictable. The best example is this project.”

“ In example of this project I saw how just idea can turn on real product.on something which can be really useful”

Find new nische for the company

Our work we started with company visit, which

is situated a bit outside of Tallinn. We were on

production aria and people who work there

explained us what kind of goods they can produce,

on what they have already worked. Mostly they

produce the glass fixing out of steel, the main

problem of which that :

“ The producers from

Chinacanmakethesame

goods for the cheaper

price in a shorter term. “

And the line of products it’s not so unique, so the

one way for them it’s to find new direction with the

new ideas. That task seemed a bit complicated and

also responsible at some point, because they were

hoping to get some real help for father developing.

They showed photos of the university which is

buildingcurrentlyinNarva,whereisusedsome

new way of glass fixing, which is really simple, but

works in a optimal way. Out of that we started to

think about using glass in contractions.

Researchingthe“WORLDOFFIXINGS”

Before going to company visit we made small

research and found all the fixings that existed and

all the areas we could work on.

Surprisingly we found very wide choice of every

kind of fixings beginning from glass fixing for

facades to the stainless still fixings for stair rails.

Our focus were::

Architecture – Provide smart solution for facades.

Wooden Architecture – Focusing on existing

problem of wooden buildings.

Boats – There are lots of stainless still details which

could be redesigned or reinvented.

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?

We made comparison matrix to understand which materials, functions and production methods

we preferred.

Our selling point has 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.

“KLIPS” is a clamp for hanging rigid panels or banners.It’s easy to install without making holes into the material.

Inspiration Workshop

Interior design office

Owr next step was decision to make a work shop

all 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.

Because there were so much details in decoration

of the work space, mostly previous projects.

That was rather interesting to look around and try

to think about each project may be it has

something in common with our work.

here was definitely a lot of fixing of different

materials.

The work space was quite big and was good idea

to divide the room on two parts by putting on

the middle of the room carton. That was heavy

material, which could give the feeling of two rooms.

Looking on that carton in the office and

thinking about material fixing we came with the

idea that we need to create something which

would hold the material in a way not damaging it

by stamping.

PROBLEM SET

Process

September

If the material is thick, it can be fixed from the edge

of the panel. But if the material is thin, the hole must

be made into the material.

How to hang up thin panels without

making holes and damaging the

material?

However, how to fix the panels?What kind of clamp mechanism toprefere?

Why our product is importent ?!

Indoor Application:

Easily handling room dividers

Fabrics are used the most

But rigid panels become more and more in use

Different materials need different fitting

Solut ionOutdoor Application

Advertising banners are everywhere around the city

They are easy to install using holes on the edge of the fabric

But very often this kind of methodwill damage the material

KLIPS its a perfect tool for fixing, hanging decorations, paintings. It is essential tool which would make an installation of the exhibition much more easy and also reliable. Especially if we speak about valuable art works, which cannot be adjusted just by plastic clip. KLIPS has modern design and different colour range.
