random long answer Qs

a paper carton soup company are producing 2000 units of prototype packaging. select an appropriate printing process for this packaging + explain why its suitable [6]

laserjet (/inkjet) - high quality text - small text for ingredients - faster than ink jet - more reliable - EoS: higher set up costs - no specific tooling required - colours + design can be adjusted - offset lithography less suitable as small print run (2000 units)

compare + evaluate the sustainability of the 2 types of packaging used to contain soup - a paper-based carton + metal can. you should make reference to: materials used + implications for the consumer [12]

metal can: - can't store soup once opened - material inside reacts w/ air - makes soup go off - shorter shelf life - more difficult to open ring-pull than can opener - e.g. especially for users w/ dexterity issues // doesn't require tools to open - easier to recycle than carton - different materials (e.g. laminate, card) require separation - easier to clean food off surface - easier to sort from other materials as magnetic - more durable during transport - less likely to damage soup // can dent if dropped - label made from paper/another material - less surface area to print information paper-based carton: - not airtight - must be stored in the fridge - shorter shelf life when sealed - safer once opened than can - doesn't have sharp metal edges - tessellate better than can - cheaper to transport // many cans can be stacked w/o crushing

compare the 2 types of chairs + evaluate their suitability for long term use in an outdoor environment [6]

explain the benefits of using CAD modelling in the development of a remote control [6]

- allows for rapid prototyping (faster than Styrofoam by hand) - iterative designs can be 3D printed (remotely) - previous versions can be edited easily so process does not degin from scracth w/ each new design - prototypes can be shared online w/ client/other designers - can simultaneously edit design - can test for ergonomics (button spacing, fit in hand) - model used for customer feedback - fine details can be accurately modelled + tested - e.g. split lines, screw fixings, battery compartments - which is impossible w/ other modelling forms e.g. Styrofoam, MDF - pigments in printing plastic

define "composite material" [2]

- mix of two or more materials - to produce a new material w/ enhanced properties

describe 3 benefits of using rapid prototyping [3]

- user feedback can be gained more quickly - snap fittings can be modelled + tested - prototype can be evaluated before production begins - checking of fit against standardised components - cost effective - life size model

explain how designers consider anthropometrics + ergonomics in the development of remote controls [9]

- way the product is designed around the body - makes remote control more confortable + easier to use - designers take into account hand dimensions of the 95th percentile - means that the product will comfortably fit the average 95% of people, making the design generally inclusive anthropometrics - e.g. palm length to determine length of remote - e.g. finger size to determine size of buttons + spacing - e.g. grip size to determine width + depth of remote ergonomics - colour on frequently used buttons - key buttons e.g. volume + channel are larger - white symbols on black bakground easy to read - shape of back of remote aids grip - spring loaded catch on battery compartment w/ grove for finger nail - e.g. buttons are easy enough to press in for users w/ arthiritis
