Abstract: This paper deals with the design and the
development of the hybrid storage shelf which can be used
as portable and foldable type by the users. This will
increase the storage utility and the aesthetics will
contribute to the interior beauty of the living space. When
contracted the dimensions of the product will be very
compact and small so that the user can transport or move
as per the user defined purposes.
Keywords: Hybrid storage shelf, Keyshot, CATIA,

1. INTRODUCTION
The objective of this thesis is to identify and analyze
various storage patterns and their problems faced by an
inmate in a typical hostel room. The various patterns of
storage and their limitations were identified through a
demographic survey and key requirements, expectations
for a better storage concept was then identified. A
detailed market analysis was carried to identify the
different type of products available in the market which
meets the expectations. Concepts for combining all the
requirements into a single product was then identified.
Construct the 3D model of the identified concept and
complete functioning of the model was rendered in
virtual reality and cost analysis was conducted. The idea
is to create a design for feasible and sustainable Multi-
functional furniture that can satisfy the present need of a
student living in a hostel room. However, the scope of
work on such a project went beyond planning and
designing different aspects of concern. Dealing with such
aunconditional environment whose elements were
untidiness, lack of available material and financial
resources, required innovative work methods in order to
lead the project in the right direction. Sustainable and
multifunctional furniture design might increase the
efficiency of living space utilization. Usually, the normal
rack satisfies only the specific purposes like, as a
wardrobe arrangement and book shelves etc. As the
requirement increases no. of racks also to be used also
increases which in turn makes the room congested and
untidy and also consumes more space, it also increase
the cost. So a portable and multipurpose rack can satisfy
the present user need. By making a new concept, the
Space and location constraint can be reduced to a large
extent.It should be also easy to handle and access items
since all are stored in single rack.
2. PRODUCT DESIGN AND PROCESS
In the present concept of design, various product design
processes are established on different aspects. The
process shown below, for example, is "The Seven
Universal Stages of Creative Problem-Solving," outlined
by Don Koberg and Jim Bagnell. This series of process
helps designers formulate their product from ideas. This
process is usually completed by a group of people and
designers, i.e. industrial designers, field experts,
engineers, etc. depending upon the products involved.
The process focuses on figuring out what is necessity,
brainstorming possible ideas, creating mock prototypes,
and then generating the product. In real case that is not
the end of the process. At this point, design engineers
would still need to execute the idea, making it into an
actual product and then evaluate its success by seeing if
any improvements are necessary.
The design of new products and it process has
experienced huge leaps in evolution over the last few
years with the rise and adoption of 3Dprinting. The
evolution of new consumer-friendly 3D rapid prototype
printers can produce dimensional objects and print the
prototypes upwards with a plastic like substance.
The design process follows a guideline involving three
main sections:
 Analysis
 Concept
 Synthesis
The later two sections are often taken care, depending
on how often the design needs updating, to improve or to
better fit the criteria. This is a continuous loop and
repeat for the optimisation, where feedback is the main
component. If we look into more and break it down even
more, the seven stages specify how the process works.
Analysis consists of two stages, concept is only one stage,
and synthesis encompasses the other four.
Analysis
 Accept Situation: The design engineer should accept
the reality and the current practises for the better
understanding on the scope of the project. The
detailed study of the current systems will put more
light in the concept generation.

 Analyse: Analysing the situations and the current
problems will help to conceptualise the solution for
those problems or necessities. The analysis can be
made with many surveys, questionnaires and
feedback forms. This can lead to form a requirement
list.
Concept
 This phase will involve in defining the problem and
the solutions for that. The concept phase can have
more ideas and alternate designs. The feasibility
study on these concepts will figure out the best
affordable design for the users.
Synthesis
 This phase will have all the brainstorming sessions.
This will be irrespective of the possibility of
executing and without considering all other basing
possibilities. This can gather more ideas and
features for the concepts.
Select: After all these process, the designers will have
ended up in selecting a suitable concept which can
satisfy the user necessities. In the other stages we have
to check how to implement and manufacture the concept
to real world.
 Implement: This is where the prototypes are built,
the plan outlined in the previous step is realized and
the product starts to become an actual object.
 Evaluate: In the last stage, the product is tested, and
from there, improvements are made. Although this is
the last stage, it does not mean that the process is
over. The finished prototype may not work as well
as hoped so new ideas need to be brainstormed.
3. DESIGN INPUTS DERIVED FROM SURVEYS
Based on the questionnaire and the surveys done,
the product design got more optimised. The
optimised methodology will make the processes
more focussed to the final stage of the product and
its effectiveness. The revised needs and target
specification is as shown below.

Benchmarking will provide better resolutions in the
steps and the parameters to be attained during the
process. The proper benchmarking will make the
concept more competitive and the designer can assure
that the product is having all the features that the
competitors provide to the end users. This will ensure
for a better environment for the product in the selling
market
4. MECHANISM AND MATERIAL SELECTION
There are many lifting and expanding mechanisms
available in the market. The simplest one is the screw
jack mechanism which is widely used in the lifting of
heavy weights. The requirements doesn’t call for such
bulky mechanisms for this design. The next sorted out
design was chain and sprocket, but it will call for
higher maintenance cost and noise problems due to
the loosening of the chains. The researches came to the
scissor lift mechanism which can give a maximum limit
of expansion in its elongated position and the
minimum in its contracted position. So this will be
feasible for the current concept. Its symmetrical inks
will provide more rigidity to the structure and will
help to handle necessity load for the user purposes.
Regarding the material selection of the product, first
thing we have to look is the rigidity, availability and
feasibility to manufacture. It’s easy to get the Mild steel
or stainless steel but when we consider about the
portable feature for the user it will be bulky. So the
best option in the metals will be Aluminium, which can
impart more strength and anti-corrosive. This will give
a good look and less weight for the entire structure but
it may not be able to withstand as much as load that
stainless steel can bear. Still it can be considered if the
user is ok with the load capacity of the aluminium. If

the cost has to be again reduced so that the product
will be affordable for larger consumers, then pipes can
be made of PVC with higher hardness and the
structure with Aluminium itself.
5. MODELLING PLATFORM
The platform used for 3D modelling is CATIA. There
are many 3D and 2D software are available in market.
The initial layouts and concepts can be generated by
2D software and later the frozen concepts can be
modelled by 3D software. CATIA is good in sheet metal
modelling and can be transferred to CADCAM
manufacturing process. When it comes to the
presentation levels of the concept, CATIA can bring out
the best rendered images with KEYSHOT 4 software.
This will help in creating a better impact of product
images in the posters, brochures etc. The complete
package of the Software can perform preliminary
analysis of the load carrying capacity of the product
and draw out the BOM of the assembly. These features
will help us to have a complete package of design and
the manufacturing assistance.
6. 2D – ASSEMBLED SKETCHES
The models are generated in the 3D platform and
assembled. The 2D sketches of the same are shown
below

disassembly of the product
9. CONCLUSION
The objective of this thesis was to create a design for
feasible and sustainable Multi-functional furniture that
can satisfy the present need of a student living in a hostel
room. However, the scope of work on such a project
went beyond planning and designing different aspects of
concern. Dealing with such a convoluted environment
whose elements were untidiness, congested living space,
and lack of available material and financial resources,
required innovative work methods in order to lead the
project in the right direction. Sustainable furniture
design might increase the efficacy of living space
utilization. Usually, the conventional rack satisfies only
specific purposes like, as a wardrobe arrangement, book
shelves. As the requirement increases no. of racks also to
be used also increases which intern makes the room
congested and untidy, it also increase the cost. So a
portable and multipurpose rack can satisfy the present
need. An open rack that can accommodate all materials
like books, clothes and even computer can be developed.
So a survey was conducted among different students
from different colleges, Based on the survey needs are
identified and converted to design specification
accordingly and different concepts were developed. The
free hand sketches are drawn and part modeling was
done using CATIA modeling software. The final
assembled product was then rendered to maximum
quality in terms of aesthetic and style.
