Concept Feasibility Comparison

  Concept C Concept FCan our system be designed?  Yes YesDo we understand what we are trying to do and have we decomposed the design adequately to insure our understanding and to enable the clear assignment of responsibilities?  Yes Yes

Is the technology available and robust? Available, possibly

robust Available, robustIs the design likely to meet all engineering specifications and satisfy the customer?  Possibly PossiblyHave we addressed all required features and functions?  Yes YesDo we understand the performance limits of our design and whether these limits are acceptable? Yes YesDo we have the capabilities and resources (people, funds, time) to realize our design (before investing heavily in engineering activities)?  Possibly Possibly

Concept F: Overview

Object sets raised and lowered independently on cables connected to pivoting arms

Pivoting arms are positioned 90 degrees to one another

Upper section of apparatus rotates on human-powered turntable to change object sets

Pivoting arm movement provided by electric linear actuators (expanding cylinder)

Linear actuators controlled remotely

Object travel electronically controlled by limit switches
