The Design

About TriPawd 犬用車椅子

TriPawdは、前脚の一本を失った犬のためにデザインされた犬用車椅子です。大径の後輪二輪が装置の安定性と機動性を高めます。曲げ加工を施した金属パイプフレームに取り付けられた小さな前輪が、グラスファイバー製のチェストカップを支えます。フレームを湾曲させることで、残された脚が干渉することなく歩けるだけの十分なスペースを確保しています。支柱は高さ調整が可能で、さまざまな体格の犬に対応します。ストラップ類を一切使用していないため、犬は自ら装置に乗り降りでき、飼い主の手を借りずに座ったり伏せたりすることができます。

Behind the Design

Unique Properties: This project was to design an assistive device that will help 3 legs-handicapped dogs walk and stand on their own. Two large rear wheels were used to improve both the stability and mobility of the device, while a front small wheel on the metal tube frame connecting the two wheels provided strong support for the chest cup. The bent metal frame provided just enough space for the dog to walk without any interference of his legs. The pole is height-adjustable for different sizes of dogs.
Dimensions & Packaging: 685 mm x 630 mm x 550 mm
Tags: Handicapped dog, dog wheelchair, animal assistive device, product design, product innovation
Production Technology: Bent metal frame, fiberglass chest cup
Design Challenge: One key aspect while collecting measurements of the dog is that dogs don’t understand what is happening in the same way human subjects would understand. Another challenging factor was that animals are not able to communicate and provide the same level of feedback as a human, regarding comfortability and overall effectiveness of the device. Since it was such a huge challenge to measure the accurate size and shape of the dog’s upper body, the designer produced a series of different-sized chest cups, followed by the repetition of measurements.
Research: This project introduces the design and development of a new assistive wheeled product for handicapped dogs. The device is specifically targeted for a 5-year-old mastiff who lost one of his front legs due to a gunshot accident in California, U.S. This study involves research, design, and usability testing with a series of working prototypes on the dog.
Inspiration: Sadly, the dog had no bone structure left due to his left front leg being completely removed from surgery. Because of this, the design direction was focused on a wheeled type of mobility device called a dog wheelchair due to its similar functionality to a human wheelchair. This device allows the dog to jump on and off easily without any strapping mechanisms on his body. This will also allow the dog to sit and lie down freely without his owner’s assistance.
Project Duration: The project started in July 2019 in Tempe, Arizona, U.S, and finished in December 2020.
Operation Flow: This device helps 3 legs-handicapped dogs walk and stand on their own for longer periods of time without any assistance from the owners.
