Dualcon: Redefining Mobility with Adaptive Design

Chi En Kuo’s Dualcon merges walker and scooter for seamless independence.

Traditional assistive devices often fall short in providing the versatility required for users to navigate various daily scenarios. Many are tailored for specific conditions, limiting their effectiveness when users transition between different activities or environments. Recognizing this gap, Chi En Kuo developed Dualcon, a multi-supply assistive device that seamlessly combines the functionality of a walker and an electric-assisted scooter.

Dualcon’s standout feature is its dual-mode capability, allowing users to switch between independent walking and powered mobility with ease. The device’s design ensures that operation remains simple and intuitive, catering to users who value both autonomy and convenience. This adaptability not only enhances daily mobility but also promotes comfort and confidence for individuals facing mobility challenges.

The engineering behind Dualcon is both robust and innovative. The connection between the walker and scooter is secured using three fixed positioning points: a pin with a screw structure, an adjustable clamp, and a latch inspired by train couplers. This system guarantees stability and safety during use, while mode transitions can be completed in a few straightforward steps or with electronic assistance. Such thoughtful design ensures that users can confidently navigate both short and long distances, whether shopping, strolling, or moving within their community.

Operating Dualcon is straightforward. To combine the walker and scooter, users align the components, secure them with a locking pin, and activate the pedal mechanism for a stable connection. Switching back to walker mode is equally simple, involving the release of the locking mechanism and a smooth separation process. This intuitive interaction empowers users to adapt their mobility device to their immediate needs, fostering greater independence and flexibility.

Developed at Shih Chien University between July 2024 and January 2025, Dualcon has already garnered significant recognition, winning the Iron A' Design Award in Vehicle, Mobility, and Transportation Design for 2025. This accolade highlights Dualcon’s commitment to practical innovation, technical excellence, and user-centric design, setting a new benchmark in assistive mobility solutions.

Dualcon exemplifies the future of assistive devices—where adaptability, ease of use, and thoughtful engineering converge to enhance quality of life. As mobility needs continue to evolve, solutions like Dualcon pave the way for more inclusive and empowering design in everyday living.
