These are images of the sixth prototype.
This is similar to the 5th assembly idea with the modular concept but an adjustment was made to the interior section. From V support to Zig Zag support. This reduces the number of parts and thus reduce manufacturing costs.
From the previous no.5 prototype the side flaps goes in without any slot in the interior section to double secure but in this prototype 6 a small 5mm slit is made on the bottom ends of the zig zag interior flaps to allow the side outer flaps to slot and lock in place.
The entire form is reduced in size to make it more tight/stiff and firm.
Elimination of rounded edges allows easier and neater folds, thus also allows modularity in structure. Any forms of modules with the similar shapes and angel tilt could fit on or at the sides upon each other like a set of modules.
From the previous versions of experimentation that i have made, I have made some conclusions and decisions.
These are based on the points and outcomes of the product which involves the amount of material used, the various types of materials used, the amount of time and effort took to make a single module, the number of pre-cut parts and pieces, the bonding methods used, also the strength of the final outcome, the ease of manufacturing and also pre-fixing on the consumer end.
I have move on to construct some more ideas.
I settled on this modular design idea that brings back to the idea of stack-ability, easy shapes, the game of tetris and also the concept of building blocks.
I came out with a design that can be constructed out of pre-folded cardboard planes with a few cuts and slots and abit of velcro connection (for easy disassembly for storage) (on the textile part that is interchangeable) but without the use of any glue or tapes.
Thus, as discussed :
this will ease manufacturers to produce the moulds for the standard part pieces.
this would also reduce manufacturing time and cost with the elimination of glued parts or layering.
but overall, it may look as an easy design as all the complications are hidden in the design and the hard work are already being made during the manufacturing process.
to an extent it is agreeable that the simpler the form, the easier the making process would be and also the more innovative possibility it creates for us. For example a cuboid is simpler than an organic sphere but it has characteristics of a planer surface area that allows stackability.
This idea is still similar to the furniture set, It is still a furniture set.
Just that the form does not restrict it to a particular function.
The method of making will be as easy as keeping a book in a bag and zip it up.
No glue will be involve.
All parts can be constructed out of a sheet of cardboard. (size depends)
There will still be 3-5 modules in the furniture set.
These modules can be stack of join together for a particular function.
These modules can be disassembled and collapsed when not in use for easy storage.
These modules will have fabric/textile on some of its outer surface parts.
Light weight is a factor look upon for kids easy mobility.
The design comprises of 3 modules.
Each of which are of different sizes. (small, medium, large)
Modules can be stacked upon each other to built a tower. (like building blocks)
Modules can be mix and match. (like tetris)
*modules as its own is actually a kids chair and table, but when place together it can be a combo lounge with side table like my design for prototypes 1 to 4.
Therefore, modules are not labelled as a chair or table. Its form is universal… to a certain extent though.
I have various versions of this idea.
Below are two of these ideas.
These images shows photographs of the different prototypes which i have made from 1 to 4.
Prototypes were constructed individually based on the design considerations made and the aspects of further improvement form its previous versions.
All prototypes are of full scale.
All prototypes are collapsible.
The description below are only brief observations.
*reference back to previous posts of photographic documentation is advised for recollection.
Made as a benchmark to examine structural strength, overall form, functionality, manufacturing possibilities and also user friendliness.
The first use of velcro connections as a unique way of joining the parts together.
The use of exterior flaps to secure the overall form.
The use of cuts instead of folds.
VELCRO & GLUE
The exterior flaps are a visual distraction to the continuous outline of the form. (rigid and exposed edges)
The structure lack base support can covering.
More interior structural element could be added to improve the strength.
The width is too wide (based on initial product testing)
Made as an improvement step from the previous one.
Overall structure made tapered in the center part to reduce width for better ergonomics. (as discussed after initial product testing)
The use of interior flaps that locks. (top and bottom only)
The elimination of exterior flaps to enhance side profile.
The construction of a full outer shell perimeter covering. (leaves no exposed parts)
VELCRO, GLUE, INTERIOR LOCKING FLAPS
Structure looks elegant.
Overall strength improves.
Too many components.
Abit more of pre-manufacturing work to be done.
Construction of the full length shell covering is tedious with the inconsistent widths. (due to the taper)
Internal flaps allow gaps to be seen between the shell an the main body.
Made to improve both strength and finishing.
Design had a size reduction on width. (270mm to 200mm)
No tapering involve.
Main part constructed with layers of cardboard planes to add thickness as surface area for the velcro to fit all over the perimeter
No flaps were involve in this design.
Abit more interior triangular planes were added.
VELCRO, GLUE, BASIC GUIDING SLOT
Overall strength improves more.
Still too many components.
Still abit more of pre-manufacturing work to be done but easier than the 2nd one.
Structure looks more balance with the consistent width.
Side profile shows the raw corrugated aspect of cardboard.
Made as an alternative method to the 3rd prototype.
The elimination of velcro connection.
Main structure made of several cut planes glued together to give strength and thickness as well as space for the
interlocking flaps to go through.
GLUE, BASIC GUIDING SLOT, INTERIOR LOCKING FLAPS
Strength similar to 3rd one.
Raw corrugated aspect of cardboard could only be seen from the top and bottom side faces.
A much more cleaner design.
These are the visual comparisons of Prototype 1 and 3 when the textiles are involved with the design.From the results and the experimentation that i have done, it is possible that i might not go on with this design but instead I will similar, better design with a combinations of all the aspects of design and manufacturing listed above.
“Building blocks, Tetris, Easy shapes, Pre school kids (growth development stages)
Parent and child bonding/interaction, Using of mix materials (fabric of textiles to add character to design)”
Characteristics of collapsibility, Stackable, Light-weight Eco, flat packed, DIY, user friendly etc. as discussed will stay in the next design refinements.
These are the process documentation of the forth prototype.
This method requires thick layering (x3) of the side walls on the main frame structure.
Reason for the layering is to allow adequate slot/space for the flaps of the shell pieces to *lock in.
This method is an effort to reduce the percentage of velcro used and also to hide most of the corrugated sides of the cardboard planes. (cleaner side profile)
More detail-lings can be seen on the photos below.
