About Ecool Kev Ua Haujlwm Tseem Ceeb: Lub Tsheb Kauj Vab Kev Sib Koom Siv Modular

Ntawv Qhia: Ecool yog ib lub tsheb kauj vab modular tsim los rau kev sib koom siv (shared mobility) hauv 15-feeb lub nroog. Lub cev tsim khoom uas siv kotaw pauv ib ntsiab rau kev zom me tuaj (one-step folding mechanism) txo qhov chaw nres tsheb thiab txuag qhov chaw nyob hauv nroog. Txoj kev zom me no ua tau yam tsis txhawj txog kev khoov cev, uas pab txhim kho kev nkag mus rau cov neeg muaj kev txwv txog lub cev. Cov chaw them nyiaj hluav taws xob raws pheeb suab pab txhawb kev tswj hwm pab pawg tsheb thiab txo qhov poob ntawm cov cuab yeej. Lub cev tsheb yog tsim los ntawm cov txuj taws recycled aluminum siv txoj kev die-casting, thiab cov recycled ABS thiab PC plastic ntxiv rau kev khov thiab siv tau ntev. Cov ntsiab modular pub kev hloov kho yooj yim thiab kev txuag khoom yooj yim, ua rau lub tsheb kauj vab siv tau ntev dua.

Production Technology: Ecool production combines advanced materials with modern manufacturing. Its recycled aluminum frame, made via diecasting, ensures strength and precision, while recycled ABS and PC plastics enhance durability. Iterative prototyping used 3D printing for testing and CNC machining for final parts. This blend of sustainable materials and high tech processes underscores Ecool is commitment to innovation and environmental responsibility.
Design Challenge: The primary challenge in designing the Ecool scooter was creating a simple, optimal folding mechanism that allowed operation without bending, catering to users with limited mobility. This involved extensive ergonomic research and numerous design iterations. Additionally, compliance with diverse regional safety standards impacted the scooter is specifications. Efforts were also made to incorporate sustainable manufacturing processes to minimize carbon emissions.
Research: The Ecool design study aims to enhance sustainable urban mobility, aligned with the 15 minute city concept. It focuses on creating a foldable, modular scooter that saves space, meets diverse needs, and uses sustainable materials. Participants including delivery personnel and commuters, prefer compact, versatile transport that reduces clutter and improves accessibility. Ecool supports shared mobility, lowers carbon emissions, and influences urban transportation policies for a sustainable future.
Inspiration: Inspired by the challenges facing shared scooters in Europe and bikes in China, including theft, vandalism, and sidewalk congestion, this project aims to redefine sustainable urban mobility. The excessive production and abandonment of scooters not only pose environmental threats but also burden enterprises economically. With rising skepticism towards shared transportation models, there is an urgent need for innovative solutions to ensure sustainability and reduce urban carbon emissions.
Project Duration: The project was initiated in January 2024 in Hong Kong and the design was completed in May 2024.
Operation Flow: The Ecool scooter is designed for intuitive use, featuring a foot-activated one-step folding mechanism for quick, effortless compact storage. This design enhances accessibility, including for users with physical limitations.

A smart system connects to a mobile app, offering real-time data on scooter availability, battery life, and route optimization for efficient travel. The modular design allows easy customization and maintenance, extending the scooter’s lifecycle and performance.
