DoD & Friends 1 st Progress Report Perfect Pushup Trainer

Design Problem and Motivation Stemmed from military PFA (physical fitness assessment) standards and regulations o 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 o Looking for a method to capture this aspect

Challenges Actual accurate measurement of the pushup itself o Range of tolerance Universal fit for a multitude of users o “One size fits all” Size of device o More capabilities leads to a bulkier system o Electric vs. Purely Mechanical

Existing Designs Existing Products o U.S. Patent US “Device and Method for Performing Push-up Exercises” o U.S. Patent US “Push-up Exercise Unit and Device” Conclusion o There are only a few existing competitive designs o Speaks to originality of our design o Most existing products have a different primary function from our design

Applicable Patents Existing Products o U.S. Patent “Training Device for Basketball Players for Developing Proper Shooting Technique” o U.S. Patent US “Basketball Shooting Training Aid” o U.S. Patent US “Electronic Basketball Shooting Coach” Conclusion o Basketball shooting mechanisms have the same function as our design o Sensors such as accelerometers and inclinometers can be utilized o 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 o Indicates when correct pushup form is performed by measuring elbow angle o Ergonomics o Affordable o Durability o Lightweight See FRDPAARC Table for more

Market Research Data based on 108 online survey responses Would you use it? o 49.1% Yes, for personal use o 22.2% Yes, in a public gym Would you buy it? o 66.7% said No How much should it cost? o 45.4% said $11-$20 Where would it be sold? o 50.9% said in Sporting Goods Stores

Accomplishments and Next Steps What have we done so far? o Brainstorming ideas – generated 8 ideas, 5 eliminated with aid of Professor Lipken o Final design chosen out of remaining 3 through team interests and further input from friends and Professors o Researched existing products and patents o Market research through Google Survey o Began forming initial concepts and innovate design solutions What still needs to be done? o Further customer polling (Market Research) o Develop concepts and chose the best solution o CAD models 2D/3D o Prototyping
