INTRODUCTION & MISSION STATEMENT

Last year’s team Mission Statement:

• To simulate a long shooting distance (up 90 M) within indoor range space

(18M) to validate emulation methodology & algorithms with proof of concept

• Designed a model that could emulate different ranges based on an algorithm.

This Years Mission Statement (produceability & affordability):

• Design shippable, transportable, lower weight/cost & easily assembled stand

that addresses identified issues with last years final prototypes

REQUIREMENTS

& DESIGN SPECIFICATIONS

Requirements (Carried over from pervious year):

• Emulate 18-90m shooting distances

• Collapsible & Portable

• Utilized scaled emulation target faces

Design Specifications/goals:

• Manufacturability: Cost-Effective, simple design, easy to maintain.

• Affordability: Competitive sale price, minimum storage space & weight.

• Transportability: Fit to standard shipping, resistant packaging, and lightweight.

• User-Friendly: Easy of setup and, easy to move around, simple to repair.

• Operational Safety: Minimize hazards, maximize structure factor of safety.

First team goal: prove concept, our goal: make cost effective

EVOLUTION OF EMULATION STAND DESIGN

• Design approach evolved from original stand R&D efforts to increasingly higher fidelity deign solutions over two team life span

Design evolution critical to developing optimized design solution

Team 1 Phase 2014-2015

Team 2Phase 2015-2016 Team 1 interim Phase summer 2015

PROJECT SCHEDULE

2015

2016

All key schedule milestones were met

PRINCIPAL DESIGN REQUIREMENTS

Top Case:

• Shelving units with two pulleys on top shelf

Target Cage:

• Cage frame developed from shelving units

• Maintains stability during operation by 8 wheels

on each corner guided by the main frame corner

columns

Bottom Cage:

• Four wheels mounted at the bottom of the cage

for mobility

• Particle board where Target Cage sits

Motor:

• Winch motor used along with pulleys to drive

target cage position

Design & Analysis performed utilizing SolidWorks

CRITICAL ANALYSIS AREA

• Buckling of support stands

• Tipping Angle of fully erected stand

• Deflection (Induced by Tension of

Target Cage) resulting in biding &

resulting destruction by winch

• Ability to fit into max UPS& FedEx

shipping limits: Weight: 150 lbs (70 kg).Packages: 165 inches (length and girth combined)Packages: 108 inches in length.

• Use of SolidWorks Key to success

Failure to solve any key issue would have doomed design

Bill of Materials

Cost goals met: reduced cost by 60% over last design

RESULTS & DISCUSSION

Design Objectives:

• Manufacturability: Design was composed of off

the shelve components. Final design dimensions

fit standard shelving unit dimensions.

• Affordability: Cost was reduced by %60. Weight

was reduced to 150lbs (w/out target foam)

• Transportability: Final Dimensions: Assembled:

5’x2’x14’; Disassembled: 8”x27”x14”, Weight: just

under 150lbs

• User-Friendly: Shelving units: Easy to

Assemble/Disassemble and light weight, No

special tooling to build stand; Simple to

• Operational Safety: Overall Structure: Strong and

Stable

Ultimate goal: Design for produceability & affordability

2016 SENIOR ARCHERY DESIGN VALIDATION
