This project is a future-oriented toilet assist device designed for the elderly, aiming to address the challenges of an aging society. As mobility declines with age, many seniors face difficulties and safety risks during toileting, such as instability and the risk of falling. This design focuses on supporting key movements in the toileting process by integrating ergonomic principles and mechanical assistance. It helps users sit down and stand up more safely and independently, reducing reliance on caregivers. The goal is to enhance daily comfort, dignity, and independence for elderly users.This design integrates multiple innovations in elderly toilet assistance: it reduces the risk of falls through motion analysis and ergonomic support structures; applies TRIZ theory to create a combined system of support, guidance, and assistance; features modular components adaptable to various home and care environments; uses mechanical linkages instead of complex electronics to lower cost and maintenance; and emphasizes emotional comfort and dignity in its appearance and interaction. Overall, it reflects a future-oriented approach that blends technological innovation with human-centered care.This design reflects human-centered care through safety, health, and ease of use. Ergonomic support structures reduce the risk of falls and ensure toileting safety. Proper posture is encouraged to relieve joint pressure and prevent common health issues. The mechanical system requires no electricity and is easy to operate, allowing elderly users with cognitive or physical decline to use it independently. Overall, the design respects the physical and emotional needs of seniors, enhances their quality of life and dignity, and embodies a people-oriented approach to aging-friendly solutions.This design integrates formal, functional, and technological aesthetics, showcasing the harmony of human-centered and rational beauty in future elderly care products. Its clean, gentle appearance and warm colors create a welcoming, non-medical atmosphere that enhances emotional comfort. The structure is compact and efficient, with forms that directly serve function, achieving a balance of practicality and elegance. Through smart mechanical design and the application of TRIZ theory, it demonstrates low-energy, high-efficiency technological beauty. Overall, the design unifies visual, functional, and technical elements, reflecting the concept that "care is aesthetics."
