Problem Statement

Small sized industry partners do not always have internal engineering design capabilities.

A market opportunity exists for a more functional design.

The process could enable the collaborative transfer of e-Design knowledge.

Approach and Methods Three different potential design concepts

identified:

Cable on Pulleys Straps on Pins Roller Chain Option

Use the e-Design Ontology’s framework for:– FEA and ANSYS analysis– Design decision process– Design optimization

Related Works Drawbacks with current design:

– Exhibits sway greater than 20”– Breakage of cables after about 350 cycles– Quick release can cause the mast to come crashing

down

Competitor products: – Costly– Rise to the 30 feet height

can take significantly longer than the desired speed for the payload

How Ours is Different Design process utilizes high end design

methods and tools to verify and validate.

Provides knowledge of the interoperability between two different CAD systems (Pro/E and Solid Works)

Technology Transfer of design knowledge from UMass e-Design team to an industry partner

Captures and maintains semantic information using UMass Amherst’s ontology-based e-Design framework

Deliverables and Benefits

Deliverable:– A completely developed and validated design

specification to enable production.

Benefits:– Ontology knowledge instance information– Sales in an initial estimated quantity of 1000 – 3000 – Creation of 50-60 jobs in the Precision Machining

sector of the Western Massachusetts region
