FLEXIGLASS_BASIC MODEL

Last crawled date: 1 year, 11 months ago

PREAMBLE

To design these sunglasses for the rural community of Guatemala I have taken into account the following considerations:

1.What are for children in a special rural area in which any object in the developed world, can have an iconic attraction and fun, which is why I tried as an attractive and practical toy.The TOP MODEL includes the possibility of including a box to store the folded glasses.

2.What by bioclimatic uniqueness of this place, children are more susceptible to disease Pterygium . For this reason, the design is adjustable wrap to prevent the incidence of intense sunlight and wind that are causing the disease.

3.What by the traditional culture, can add value to the design, creating custom painting sheaths for stiffening the legs I propose for the Top Model as well as a textile sheath for the belt neoprene propose for PLUS Model and natural rubber sheaths for the terminals of the rods as I propose for the BASIC model.

4.What anthropometric cranial structure by having children of Central America, I designed the bridge in a clean way without bend in the bridge and wider than the average standard in anticipation EPICANTHAL EYELID that can occur in the town of Guatemala.


BASIC MODEL
Integral design glasses in soft material that I propose in the technical specifications, with an appropriate degree of elasticity so that this object can not cause any harm to the children for their handling and use, especially for its gaming culture in weathering. It will complement added to the terminal pads of the pins, in spongy material.
Propose a variety of color finishes as materials of local crafts.

Estimated price of the pads 2,5 x 35 x 0,4 cm  5,5 gr. [ 0.1 $ ]

DIMENSIONS & NOMENCALTURE

55/20 110

Frame width: 150mm
Bridge Frame 20 mm
Temple length: 110 mm

Lens width: 55 mm
Lens height:35 mm



TECHNICAL SPECIFICATIONS (general for all three models)
_____________________________________________________________________________________

1 THE MATERIAL
I chose the (2-oxepanone, homopolymer of Perstorp Polyols Inc) polymer material first so that the design I propose to have a soft frame in order to comply with all international safety regulations Sanitary requiring this type of objects to be used by children.

2 WAYS TO FRAME
Secondly, the shape of my proposal is a way to infinity (∞) perfectly fits the face surface area enveloping the incidence of sunlight.

3 THE DESIGN OF CRYSTALS
Propose that the crystals are slightly countersunk elliptical according to experts who are the best format to engage the glasses facial eye socket and leave no loophole for the lateral penetration of sunlight.

4 THE SUITABILITY OF GLASSES
To meet the fundamental requirement that claims the challenge: the glasses are for children climate zones with extreme solar radiation, which must be protected to prevent rural the communities of Guatemala is Pterygium (Known in the U.S. as Surfer's Eye) propose :

4.1 A comprehensive soft, adaptive and envelope, structural soundness armor to absorb impact from falls and / or shock, as are glasses for children.

4.2 The rods are built on the same frame and are retractable automatic folding by the flexibility of the material that I propose and the modular design of the folding zone in which the material is formed into perimeter grooves shape and variable thickness that confer the Near an adaptive flexibility that makes rods are always folded.

4.3 The goodness of fit of the eyewear to the head structure of the child will be consistent with the setting of the slits that form the hinge pivot.More or less section section, depending on the degree of compression to the rod to be adjusted, depending on the type of the child head.The adjustment of the hinge pivot and coupling be parameterized in terms of the degree of torsional stiffness of the material.

4.4 As an added value and bumper protection and falls propose a neoprene tape adjustable skull which is regulated in the terminal itself with a simple pin hole.

5 El PRODUCTION PROCESS

As specified in the challenge, I propose the design can occur with the proposed machine, since only the material used http://store.makerbot.com/flexible-filament and requires no mechanical elements, or ancillary to mount the spectacle as pins, folding system ....
Thus the costs and the production process "in situ" is more accessible to the productive structure of the rural area in which is implanted drops.

6 ADDED VALUE

Since the glasses are for children from a rural culture that is still pronounced the differentiating role of the sexes propose customizing rods sunglasses pods acetate which engage with a simple click and you each user can put their favorite stickers.

_____________________________________________________________________________
And lthough specifies a design challenge for children, it would be interesting to propose another specific design for girls, given the matriarchal nature of these communities in Guatemala.
______________________________________________________________________________

CONCLUSION

To comply with all specifications that the challenge claimed, Antonio Pinfor proposes the design of a soft glasses © Flexiglass integral mount and auto-retractable rod that can occur in (XXXXXX) ,does not need any external component assembly and adjustment as are the hinges that make glasses mismatch unusable very soon and short term.
To attract the interest of children to use lkos glasses,aesthetic and recreational plus with manual insertion of covers painting is added to the children likes her glasses as her own toy and get used to carry as the Pterygium prevention.
