1. Minimize half Count
Look for ways in which to mix components. as an example, several
physical science housings use living hinges rather than a knuckle
hinge. once routing wires, select wrought guide options, or use a
heat-formed guide (like in recent LazerTag guns). And speaking of
minimizing half count...
2. integrate Fasteners
Whenever potential, build the assembly options directly into the
components, rather than victimisation screws. Snap fits are usually
even as secure and need no tools to assemble. typically screws are
necessary, however use sparingly—fasteners will consume the maximum
amount as fiftieth of assembly labor. One factor to note: Snap fits
will increase the price of injection-mold tooling, therefore take
care to style the components to be injection-molding friendly.
3. Give components Clear Orientation
Related to the thought of unique connections is exclusive
orientation: If there's a right and wrong orientation for
components to be assembled, build it obvious that method is
correct. Even higher, build it not possible to assemble the
components within the wrong method. For spherical components, this
might mean simply having a notch, however with additional
complicated shapes, this could give a chance for a few inventive
style.
4. Design for Real-World Tolerances
Finally, ensure custom elements may be factory-made simply.
Tolerances garner, and a minor variation in every operation will
add up to an enormous problem—especially if your style isn’t ready
to accommodate the variation.
Whenever potential, provide your processes the maximum amount space for error as potential. Yes, the mechanic will create your half acceptable among one-ten-thousandth, however if that’s needed you’ll unnecessarily introduce terribly pricey machining. And with 3D written elements, think about the same: even laser-sintered have variation, and it’s price considering however these tolerances can match along.

2 how implementing them will lead to improvements in the product assembly process. Present four rules that could be used to design a product for assembly and explain [8 marks] Table Q2 itemises the precedence and timing information that is required to complete the assembly of a product. For an assembly rate of 60 per hour, determine the minimum number of stations required and through the application of the Largest Candidate heuristic, devise an assembly task grouping.

Question 1- Assembly Line Balancing A ball-bearing assembly firm wants to set up an assembly line that must have an output of 60 units per hour. The work elements, task times and their precedence relationships are shown in Table 1: Table 1 Work Element Time (sec.)

SYNOPSIS The product manager for coffee development at Kraft Canada must decide whether to introduce the company's new line of single-serve coffee pods or to await results from the product's launch in the United States. Key strategic decisions include choosing the target market to focus on and determining the value proposition to emphasize. Important questions are also raised in regard to how the new product should be branded, the flavors to offer, whether Kraft should use traditional distribution channels or...
