ISS CHAMP

The ISS CHAMP operates on a quarter-turn cam principle, providing reliable connections to the handrail and seat track while effectively utilizing materials. It boasts a one-print setup and one-handed installation and removal. The CHAMP's internal cavity fits the handrail section and rotates ¼ turn around it, generating strong clamping force and locking with a spring-loaded mechanism. Removal is achieved through a user-accessible release tab that allows for single-handed action. Development involved iterative design and testing, resulting in an optimized strength-to-weight ratio. ABS material usage per unit is approximately 102g. Only one print is required to produce a CHAMP, making it efficient. Attachment and removal are both easy and secure, with minimal risk of inadvertent disconnects or damage. The seat track connection features maximize strength, ensuring a stable attachment. The assembly measures within ISS envelope restrictions, and multiple parts assemble by hand without tools. CAD files for various resolutions were submitted.
