BACHELOR'S THESIS

My thesis, developed in collaboration with Dentaid, focused on designing a toothbrush tailored to individuals with motor skills disorders, such as dyspraxia or spinal cord injuries. Through extensive research and user testing, the project identified key challenges faced by these individuals, including difficulties in gripping traditional handles and performing precise movements. To address these needs, the toothbrush features an ergonomic handle with a soft, textured grip for enhanced usability and control, along with a three-faced head for more efficient cleaning. The handle also includes an attachment strap that provides additional stability, ensuring the user can comfortably hold and maneuver the brush. The polypropylene (PP) used in the handle incorporates barium sulfate as an additive to improve stability and ensure the product's durability. The materials also include thermoplastic elastomer (TPE), adding extra grip. The design was prototyped using additive manufacturing and further validated through user feedback to ensure accessibility and effectiveness.
