The Issue
Developmentally delayed children lack motor
skills
and understanding of controlTherapy normally takes many resourcesPrevious design has shortcomings (named Glus)Slide4
Objectives and Goals
Engages child
P
rovides feedback to teach controlDoes not require the presence of a therapistToy is interchangeable and contains no electronicsSlide5
Designed for Customer
Therapist
Wizard mode
Mode selectionPatientFun toys – easy to interchangeDynamic and engaging movementsSlide6
Constraints
Weigh < 20 pounds
Platform
size: 16” by 16” to 24” by 24”3” in heightUse four 1/8” jacks as input pointsHave soft edges (case)Platform is plugged into an outletEasy toy detachmentPerform multiple actions (8-12)Slide7
Budget
$500 from Anschutz Medical
$750 from ECE Department
Total = $1250Projected Costs:MotorsElectrical motors & driversMechanical componentsThe project’s costs should stay within budget.http://www.yourmarketingcrew.com/wp-content/uploads/2012/03/dollar-sign.pngSlide8
Design Concept
Goal:
Move a toy that sits on a platform
Isolate toy from electronics Solution:Based on 3D Printer designMagnetically attachedSlide9
Motor Driver Circuit
Goal:
Drive three motors
Reduce costSolutionCustom motor driver circuitrySlide10
Input/Output
Goal:
React to patient’s actions of different developmental stages
SolutionUse of modular input interface: 1/8” jackProvide multiple interactive modesProvide buttonsSlide11
Risks
Device Usage
Mechanical stability
Physical danger to patientLack of engagementDesign ProcessTime constraintshttp://www.clipartbest.com/cliparts/4Tb/7L6/4Tb7L6ETg.pngSlide12
Mitigation Plans
Device Plans:
Rapid
prototyping techniquesCover for moving partsPrototype and “test” with children for feedback on level of engagementDesign Process PlansTime saving techniquesStandard components when possibleSlide13
Failure Modes & Effects AnalysisSlide14
Feasibility Analysis
3D printed parts are most prone to mechanical failure
Finite Element Analyses performed to ensure reliable performanceSlide15
Current Progress
Motor driver
s
ystem developedMovement subsystem nearly finishedReward (sound and lights) subsystem interfacedSlide16
Future Plans
January: Finalize first design
February: Test at Respite Care
March: Iterative testing and designApril: Final packaging and presentationMay: Documentation finalizationSlide17
Conclusion
No replacement for professional therapist
Platform is powerful tool (supplement)
Allows children to practiceGives parents at-home exercise Engage ChildrenProvides Children with Additional TherapySlide18
