DoD & Friends Perfect Pushup Trainer 1st Progress Report
Design Problem and Motivation • Stemmed from military PFA (physical fitness assessment) standards and regulations • Eliminate the need of eyeballing, therefore guessing, whether a pushup was performed correctly • “Perfect Pushup” would be defined using a military standard
Defining the Problem: What is a perfect pushup? • Military PFA standards and regulations • Hands slightly wider than shoulder width apart • Upper arm is at least parallel to the floor and elbows bent at 90 degrees • Looking for a method to capture this aspect
Challenges • Actual accurate measurement of the pushup itself • Range of tolerance • Universal fit for a multitude of users • “One size fits all” • Size of device • More capabilities leads to a bulkier system • Electric vs. Purely Mechanical
Existing Designs • ExistingProducts • U.S. Patent US20040097352 -“Device and Method for Performing Push-up Exercises” • U.S. Patent US7468025 - “Push-up Exercise Unit and Device” • Conclusion • There are only a few existing competitive designs • Speaks to originality of our design • Most existing products have a different primary function from our design
Applicable Patents • Existing Products • U.S. Patent 5865695 -“Training Device for Basketball Players for Developing Proper Shooting Technique” • U.S. Patent US5544877 - “Basketball Shooting Training Aid” • U.S. Patent US20110045925 -“Electronic Basketball Shooting Coach” • Conclusion • Basketball shooting mechanisms have the same function as our design • Sensors such as accelerometers and inclinometers can be utilized • Mechanical systems tend to be less complex, but aesthetically unfavorable
Solutions/Concepts • After investigating the currently marketed and similar products, the general design considerations from these patents have split our concepts into two groups: a mechanical brace type system and an electronic sleeve system. • The next step is to investigate and form these concepts and then evaluate them using design tools
Design Specifications • Functions • Indicates when correct pushup form is performed by measuring elbow angle • Ergonomics • Affordable • Durability • Lightweight • See FRDPAARC Table for more
Market Research • Data based on 108 online survey responses • Would you use it? • 49.1% Yes, for personal use • 22.2% Yes, in a public gym • Would you buy it? • 66.7% said No • How much should it cost? • 45.4% said $11-$20 • Where would it be sold? • 50.9% said in Sporting Goods Stores
Accomplishments and Next Steps • What have we done so far? • Brainstorming ideas – generated 8 ideas, 5 eliminated with aid of Professor Lipken • Final design chosen out of remaining 3 through team interests and further input from friends and Professors • Researched existing products and patents • Market research through Google Survey • Began forming initial concepts and innovate design solutions • What still needs to be done? • Further customer polling (Market Research) • Develop concepts and chose the best solution • CAD models 2D/3D • Prototyping
