In recent years, however, additive manufacturing technologies have become productive and cost-effective enough to be applied mass-scale in the footwear market, with this mode of manufacturing currently making up approximately 0.3% of global footwear market revenues, a figure that is set to rise to 1.5% of overall global footwear revenues by 2029. (SmartTech, 2019). As modern sports companies integrate these advanced technologies, some sports fall through the cracks and receive little to no attention. A prime example is Australian Rules Football [AF], the country's largest professional sports competition (Nicholson, 2021). Modern-day AF players are engaged in more frequent, high-intensity sprint efforts for more extended periods, with the ability to sustain performance across these intermittent, high-intensity activities being a paramount priority of the modern, elite AF player. This research explores how we could apply these advancements in digital analytical technology, additive manufacturing, engineered lattice structures, and thermoforming processes to enhance AF boot design by creating a three-boot lineup that tackles the positional needs of Ruckman, Center-Forwards, and Rovers. Professional Interests My goal is to innovate within the product development process and improve athlete performance while redefining the boundaries of sport. Additive manufacturing is one of those innovations that has plenty to offer the footwear sector, and I aim to employ those qualities in my product intervention. I hope to translate the gathered athlete’s feedback and data on their needs, into performance benefits as Australian Football and its athletes continue to evolve. This capstone project will embody everything the Sports Product Design program has instilled in me and a glimpse of what I can achieve in the industry. I will showcase how I design functional footwear interventions using a data-driven approach and learn how innovations in other industries can be implemented into footwear. Working in conjunction with my mentors, who are active in the industry, will help me put into practice skills that professionals value and seek in teammates at these larger companies Personal Strengths Strengths are partly like a talent, partly like a skill. They can be improved and applied when relevant; nonetheless, they are the core toolbox for accomplishing goals. The top strengths I identify with are Achiever, Analytical, Activator, Ideation, and Deliberativeness. Some of these are more pronounced than others at different stages of projects. As we move forward with the thesis project, these strengths will help me 2 accomplish a distinguished capstone that highlights my professional goals. Using my Analytical and Ideation strengths will help me innovate in a direction that is well informed and explores multiple approaches to a solution. My Achiever and Activator strengths will aid me in connecting and forming a plan of attack for the different checkpoints over the subsequent terms, helping me complete tasks with a strong work ethic. Lastly, my deliberative strength will help me reduce risks and prevent problems through innate anticipation and careful thought. Mentors To better guide my research and design process, I will have a series of mentors advise me throughout the capstone project. These mentors will consist of various active members of the footwear or aligned industries. Currently, the team consists of two titular mentors: Nathan Schultze and Cesar Idrobo, with further mentors to be added depending on the stage of the capstone project. Nathan Schultze is currently a footwear Designer at Women’s Jordan and has previous experience with the Nike Innovation (NXT) and Nike Sports Wear (NSW) Running teams. Cesar Idrobo is the Head Pattern and Sample Maker for Footwear at Adidas’ Yeezy. Meetings will occur bi-monthly with each mentor to develop concepts, refine research, evaluate prototypes, and validate ideas. Bryant Jimenez Tue 11/16/2021 11:13AM To: nathan.schultze@nike.com Hey Nathan, After going back and forth with you about my project for such an extended time, would you be wiling to be one of my mentors for the duration of my thesis? It’d involve meeting ideally once a month to update you on my progress and to get you'd design input going forward, I'm thinking close to an hour a session, but might increase closer to March. Best, Bryant Reply | Forward Schultze, Nathan * d <2 «) -> - Wed 11/17/2021 1:29 PM To: Bryant Jimenez Hey Bryant, I'd totally be up for helping you with your thesis, I remember those senior projects are a lot to take on. I think we should schedule meetings for twice a month instead though, because the 3d upper and lattice concept will need a lot of constant work. Let's shoot for sometime after Thanksgiving to set up the exact dates forthose meetings Cheers, Nate Image 1 Mentor e-mail confirmation from Nathan Schultze 3 Image 2 Mentor e-mail confirmation from Cesar Idrobo Product Classification Footwear & Last Shapes, Football, Australian Rules Sport History Australian Rules football (ARF/Footy) has been played for over 160 years. Originating in Melbourne, the capital of Victoria, the code is the most popular winter sport (Marshall , 2019). Australian Football's first appearance in Melbourne in 1858 pre-dated the formal organization of soccer, rugby league, and American Football, giving it eminence (Richardson, 2011). The game quickly became popular amongst the different boroughs of Melbourne, where schools organized weekly competitions on unused cricket grounds. Spreading to the surrounding cities of Melbourne: Geelong, Notts Country, Stoke City, Carlton, and Nottingham Forest in that order (Blainey, 2010). Thomas Wentworth Wills has the honor of being the game's pioneer and earliest umpire, who in the off-season of cricket in 1858 organized a famous scrimmage between Melbourne Grammar and Scotch College (Pascoe R. , 1995). In the city of Melbourne, these were the two best-known secondary schools; news of the proposed match reached the newspapers, and, on Saturday, August 7, 1858, The Melbourne Morning Herald reported the match (Blainey, 2010). The match between the schools has become 4 folklore, but it frames Australian rules football as a once-only invention; instead, it was an evolution of Gaelic Football amongst the youth of Australia. Just when secondary schools were becoming absorbed in Gaelic Football, young men and late teenagers were organizing matches which were to have more substantial effects on the development of Australian Football (Blainey, 2010). About a month before the notorious match, Thomas Wills had written a letter to the headmasters of Melbourne Grammar, asking for the organization of an off-season football team to keep cricketers in shape during the winter (Marshall , 2019). The modern-day variant resembled and gained much inspiration from early Cricket, Gaelic Football, and Rugby forms. Almost at once, it was a distinctive game. So quickly did it move in its own direction under its own momentum, and so often did it devise or adopt rules and tactics that, within twenty years, it was far removed from the older rugby and new soccer and was still changing (Blainey, 2010). The resemblances of in­ game traits were traced back to Thomas Wills, who ported over various attributes from the European competitions. Wills, as a youth, was sent to England to attend Rugby School, the birthplace of its' namesake football code, Rugby (Pennings, 2021). Particularly during his time in England, he became renowned for his ability in cricket, which proved to be pivotal for the sport. His desire to retain physical form during the off-season of cricket led to early versions of Australian football taking place across Melbourne upon his return to Australia in 1856. Prior to his time in England, another outstanding inspiration that tied the game to genuine Australian culture was Wills' experience with Marn Grook—having lived in the early settlements of Lexington, Victoria, where he grew up with numerous aboriginal children, learning their language and, more importantly, their games for passing the time. Marn Grook, white European colonists, described a game featuring high kicking and leaping for a ball. 'The ball is kicked high in the air, not thrown up by hand as white boys do, nor kicked along the ground; there is general excitement who shall catch it’ (Flanagan, 2008). The parallels to Marn Grook helped shape the unique forwarding system that quickly set it apart from the other football variants of the time. Alongside Thomas, Thomas Henry Smith, William Josiah Hammersly, and James Bogue Thompson met to draw up a code of rules for the Melbourne Football Club on May 17, 1859 (Collins, 2011), proving to be the sport’s first official milestone. The next significant jump came later the same year when the rules were amended to outline scoring criteria and announce the formation of several clubs within the city. This trend of constant rule amendments continued through the 1860s, where the most significant change came in the way of player contracts. 5 Prior to the 1860 season, players were not confined to any one club, a loophole notoriously seized by the Richmond club to field numerous stars from non-competing teams for their matches and tactic that won them two of the inaugural premiership titles. The dawning of the season 1866 saw the first published leaguewide code of rules, PLAN OP PLAY.GROUND IM T41X*. 1- Ba?? » - »*«*• *• u- r ’ L . . - ■ Thank You!
