Mechanical Hand Food Press Design: Penalties for Late Submissions, Learning Outcomes and Assignment

Late Submissions and Penalties

Penalties for Late Submissions

• Late submission of any item of coursework will be capped at a minimum pass mark if received up to one week late. Any submission received more than one week late will be awarded a mark of zero.
• Late submission of referred coursework will automatically be awarded a mark of zero.

Note: The School operates a strict policy on late submission. StudyNet marks all work submitted late, even by one second, as Late, in which case the above late penalties will be applied. Where genuine serious adverse circumstances apply, you may apply for an extension to the hand-in date, provided the extension is requested a reasonable period in advance of the deadline. However, you are warned that lateness due to network congestion (either at the University or on your local network), difficulty with filenames, poor time management and similar issues will not be considered as admissible circumstances. For this reason, you are advised to submit at least one hour before the deadline.

This Assignment assesses the following module Learning Outcomes (Take these from the module DMD):

1) LO1 the role and application of CAD tools in design

2) LO2 standard conventions for engineering drawings

3) LO3 produce and interpret detailed drawings which communicate production requirements and comply with the relevant standards and conventions

4) LO5 the nature and application of the design tools

5) LO6 use CAD tools to produce 3D models and drawings of a satisfactory solution to an identified requirement

6) LO7 devise and present design solutions to specified requirements

A note to the Students:

1.For undergraduate modules, a score above 40% represent a pass performance at honours level.

2.For postgraduate modules, a score of 50% or above represents a pass mark.

3.Modules may have several components of assessment and may require a pass in all elements. For further details, please consult the relevant Module Guide or ask the Module Leader.

Title:   Mechanical Hand Food Press Design

Brief:  Individually, you are to design a general food press that utilizes mechanical advantage to squeeze fruit such as oranges and lemons for their juice within. 1)Equally it shall be designed to squash and mash food such as potatoes and garlic and other semi-hard foodstuffs.

2)To be used on a domestic kitchen surface top, device thus maximum mass 5Kg.

3)To possess a mechanical advantage (MA)of 2:1 as a minimum, the MA can be higher

4)To meet all British Standards W.R.T. Kitchen appliances and their safety.

5)To be designed in accordance with known Human Factors data.

6)To cost to manufacture :  £5 each total manufacture cost

7)Numbers to be produced yearly – 5 million units minimum.

Features that the unit must have:

a)To press fruits to extract their juice (oranges, lemons, grapes, berries etc.)

Learning Outcomes

b)To press foods to mash the foods for consumption, (e.g. mash potatoes)

c)A safety mechanism to ensure that the device does not move or slip when a force is applied and the device is in action on the kitchen surface top *.

d)A mechanism to allow complete dis-assembly so that the device and/or its parts can be washed at temperature 75 ° C in any domestic dishwasher.

e)The device must be stable when in operation and withstand the following loads:

*vertical downward force of 200N applied at the swashing end.

*a hand input load of no more than 10 N applied in any direction.

f)A tray of some sort to remove the juices for the fruit squashing application

g)The device must be rust free if any metals are used

h)The device must have no sharp corners or edges.

i)The device must have a minimum of styling so that it looks reasonably appealing to the eye                                                                            

The report layout shall follow the marking scheme order and the length of the single PDF report is 5 pages max.

Important Note: Due to the Corona Virus, you may not have access to the Catia CAD modeling software, thus you may use ANY OTHER CAD software for the production of the CAD solid models and 2D technical drawings.

Failing that, as a last resort, you may produce neat hand drawn 3D sketches of the final design.

The PDF file is to be electronic and uploaded via Canvas net submissions facility.

The report MUST be laid out in the same order of the marking scheme.

For this section, you are required to produce 3 neatly drawn and well-annotated concept sketches of each of your concepts. Each concept should be labeled with title.  

Concept selection table of some type

Here you are to produce a Concept Selection table as shown in the lectures and arrive at the best concept that meets the given brief design specification. Only the best concept is taken forward from this stage on.

Embodiment Design

In this section, you will need to draw by hand, neat lined 3D sketches of your overall design.

These are better sketches than the original concept sketches showing much more detail.

Detail design, design calculations.

In this section, you are to provide detail design of all the component parts, i.e. materials of each part, how each part attaches to each other part, and design calculations to work out the forces and mechanical advantage of the device
