Sobre Cr1 Cadira de rodes

La CR1 és una cadira de rodes de fibra de carboni totalment personalitzable segons les especificacions i preferències individuals de l'usuari. La part frontal única de doble angle va ser dissenyada per seguir les línies del cos de l'usuari, permetent-li apropar-se més als objectes per millorar l'accessibilitat i la maniobrabilitat en espais reduïts. El perfil aerodinàmic del tub i la seva orientació van ser dissenyats per millorar la resistència, el confort de l'usuari en les zones de contacte amb el cos i, estèticament, per promoure una sensació de velocitat. Els protectors laterals de doble funció proporcionen protecció a l'usuari alhora que actuen com a element estructural de suport.

Crèdits, membres de l'equip i detalls tècnics proporcionats pel dissenyador.

Propietats Úniques: The CR1 is a custom fabricated carbon fiber wheelchair. Each one is unique and built around the user's individual body specifications and their desired preferences. Carbon fiber was selected not only for its performance benefits of strength and light weight, but also for the freedom to optimize the tube shape. The ovalized tubing is orientated at different angles along the frame to maximize strength and comfort for the user. The unique front-end design allows improved environmental access by allowing the user to get closer to objects.
Dimensions i Embalatge: Each chair is unique and based upon the information supplied by the user's order form which is 5 pages long and covers 9 specific measurements based upon the individual body proportions and chair set-up preferences. There are also numerous component and accessory options available to make each chair unique. The chair length dimensions are 330-483 mm, x 330-457 mm width, x 381-533 mm height.
Etiquetes: everyday performance, ultralight, custom, made-to-order
Tecnologia de Producció: Production is through a vendor that specializes in the creation of carbon fiber products and their use of a proprietary foam core fabrication process that adds additional strength and helps to absorb vibrations. Their team was able to optimize the specific material layups and the fabrication methodology. Every frame consists of two mirrored sideframes that each have 3 bonded together sections of different angles and lengths, joined with a bonded crossbar. These modular components combine with others to make each chair unique and match the user's specifications. The design was refined through FEA analysis, user evaluation and finally, through mandated functionality and durability testing ANSI/RESNA, ISO 7176.
Repte de Disseny: The key challenges were improving accessibility and maneuverability while reducing the overall weight in a fully customizable product. We partnered with outside vendors to develop special components, like an entirely new style of caster fork bearing. Its creation allowed for smaller parts, lighter weight and a smaller footprint to the chair's design and overall proportions for improved maneuverability. Another key component was the ability to customize the frame designs in as economical and manufacturable method as possible that also minimized waste. The final realization of that was the modular, 3-section design to the sideframe. Different materials are utilized on different parts of the chair to maximize durability like titanium trim rings on the footrest for wear and SMC carbon reinforced parts for impact protection when the rear wheels are removed. The foam core of the carbon fiber parts improves strength and the perception of being too delicate and fragile a material for this application.
Recerca: The background research for this project was inherent in over 30 years of being a professional wheelchair designer and user. This product was intended for advanced users who know how they want to sit and how they want their chair to feel and respond. The needs and requirements for this product are something that I live and experience every day. We also presented early prototypes to other users and industry experts for their opinions and feedback.
Inspiració: The CR1 was inspired by over 30 years as a product designer in the medical industry and as a chair user personally. I was given the task of creating the ultimate, daily-use chair and in doing so drew upon previous designs and what I would have liked to have done but wasn't able to either from a materials perspective or project parameters. The form is functionally driven but inspired by Formula 1 race cars and elements of the F-22 Raptor.
Durada del Projecte: This project started in Nashville, TN in early 2018 and was officially completed and for sale on the market in October of 2023.
Flux d'Operació: The CR1 is operated like any other manual wheelchair through the propulsion of the two drive wheels. What is improved over other devices in the market is how lightweight it is, the complete chair is only 6.8 kg and the increased maneuverability and accessibility through the kinked front-end design. The customized frame dimensions ensure a secure and comfortable fit for the user, much like a wheeled prosthetic.
