SE&A Internship

Background

Learning Pro/E during first week

Modeled “neutral assemblies” for use in circuit

breakers to maintain equal voltage across poles

Page 5: IPG Portfolio June 2009

SE&A Internship

Background (cont.)

Maxflex Handle Operator

Accessory

Functions to trip a circuit

breaker remotely

Design problem

Ergonomic issue: installation of

cables onto breaker requires

disassembly of Maxflex unit

Maxflex unit

Page 6: IPG Portfolio June 2009

SE&A Internship

Proposed solution 1

Re-manufacture both

plates in Maxflex unit

to allow unobstructed

access to bolts

Problem:

Expensive because it

will create scrap parts

Upper plate (sliding)

Lower plate (fixed)Unobstructed bolt

access

Page 7: IPG Portfolio June 2009

SE&A Internship

Proposed solution 2

Reverse bolt

positioning to allow

quicker disassembly of

Maxflex unit

Problem:

Cheap fix, but presents

inconvenience of rear-

mounted breaker

Obstructed but

easier disassembly

Page 8: IPG Portfolio June 2009

SE&A Internship

Proposed solution 3

Slot the fixed plate to

allow removal of Maxflex

unit from side

Problem:

Unconstrained unit

(lateral motion possible)

presents safety hazard

Loosen bolts and slide

plate right to remove

Page 9: IPG Portfolio June 2009

SE&A Internship

Proposed solution 4

Make L-shaped slots in fixed

plate to allow lateral removal

Unit is constrained because it

can only produce motion

downward (to turn breaker off)

Conclusion:

Solution 4 implemented after

extensive quoting process
