Dualcon Multi Supply Assistive Devices

Dualcon Multi Supply Assistive Devices is an innovative mobility solution that represents a significant advancement in assistive technology design through its dual-functionality approach, combining the independent support capabilities of a traditional walker with the powered convenience of an electric mobility scooter within a single integrated system. Developed as an academic design project at Shih Chien University between July 2024 and January 2025, this versatile mobility device addresses the fundamental limitations of conventional assistive devices, which typically serve singular purposes and lack the adaptability required to accommodate the diverse mobility challenges encountered by users across different environments and daily activities. The design philosophy underlying Dualcon Multi Supply Assistive Devices centers on enhancing user autonomy and flexibility by enabling seamless transitions between walking assistance and powered transportation modes, thereby eliminating the need for multiple separate devices and reducing the logistical burden on users who require varying levels of support throughout their day. The structural integrity of Dualcon Multi Supply Assistive Devices relies on a sophisticated three-point connection system that ensures stable integration between the walker component and the electric scooter base, incorporating a pin with screw structure, an adjustable vertical clamp mechanism, and a train coupler-inspired latch system that collectively prevent unwanted movement or detachment during operation. With overall dimensions of 1155 millimeters in length, 670 millimeters in width, and 980 millimeters in height, the complete assembly maintains ergonomic proportions while the walker component alone measures 690 millimeters in length, preserving maneuverability in confined spaces. The operational methodology of Dualcon Multi Supply Assistive Devices facilitates user-initiated mode switching through an intuitive process wherein the walker aligns with designated tracks on the scooter base, slides into position, and becomes secured through rotation of the locking pin, followed by activation of a slide button that deploys a pedal mechanism to complete the connection and provide stable foot placement for powered mobility suitable for extended travel distances such as shopping excursions, recreational strolling, or community navigation. Conversely, the separation procedure enables users to disengage the walker by holding the lock key while rotating the pin, pressing the slide button to retract the pedal and create clearance space, then physically pushing the walker forward to detach it from the scooter base, thereby restoring independent walking functionality for short-distance ambulation without reliance on powered assistance. This design earned recognition as an Iron A' Design Award winner in the Vehicle, Mobility and Transportation Design category for 2025, an accolade that acknowledges designs meeting rigorous professional and industrial standards through demonstration of solid design principles, practical innovation, and meaningful contributions to quality of life improvements. The Iron A' Design Award designation specifically recognizes Dualcon Multi Supply Assistive Devices for its competent technical characteristics, expert understanding of user needs, and creative capacity in addressing real-world mobility challenges faced by individuals requiring assistive devices, particularly within aging populations where flexibility between independent ambulation and powered transportation becomes increasingly valuable. The evaluation criteria for this recognition encompassed innovative use of materials, aesthetic appeal, functionality and performance, safety measures, environmental impact, user comfort, technological integration, manufacturing feasibility, cost-effectiveness, market viability, ergonomic design, adaptability and versatility, space optimization, energy efficiency, durability and longevity, maintenance ease, branding and identity, cultural relevance, inclusive design, and futuristic vision, all of which Dualcon Multi Supply Assistive Devices successfully demonstrated through its thoughtful integration of dual mobility modalities within a cohesive design framework. The conceptual foundation of Dualcon Multi Supply Assistive Devices emerged from critical observation of existing assistive device limitations, particularly the recognition that traditional mobility aids designed for specific conditions often fail to provide adequate flexibility when users encounter varied environmental contexts or activity requirements throughout their daily routines, resulting in compromised independence and reduced quality of life for individuals whose mobility needs fluctuate based on distance, terrain, fatigue levels, or situational demands. By consolidating walker and electric scooter functionalities into a single convertible system, Dualcon Multi Supply Assistive Devices eliminates the practical and financial burden of acquiring, maintaining, and storing multiple separate devices while simultaneously reducing the cognitive load associated with determining which device to use for particular activities or environments. The design represents a paradigm shift in assistive mobility technology by prioritizing user agency and situational adaptability over the conventional single-purpose approach that has historically dominated the assistive device market, thereby contributing to broader conversations within industrial design regarding inclusive design practices, aging-in-place strategies, and the development of adaptive technologies that respect user autonomy while providing necessary support. The technical implementation of the connection and separation mechanisms reflects careful consideration of user capabilities, ensuring that mode transitions can be accomplished through simple, repeatable steps that do not require excessive strength, dexterity, or cognitive processing, with potential for electronic assistance to further reduce physical demands on users with limited hand function or reduced upper body strength. The walker component maintains structural independence with dimensions of 690 millimeters in length and 670 millimeters in width, preserving the familiar form factor and handling characteristics of traditional walkers while incorporating the necessary interface elements for integration with the scooter base, thereby minimizing the learning curve for users already accustomed to walker operation. The electric mobility scooter component provides powered transportation capabilities suitable for longer distances and outdoor environments, addressing the fatigue and range limitations inherent in walker-only mobility while maintaining the option to quickly revert to walker mode when entering buildings, navigating crowded spaces, or engaging in activities where powered mobility would be impractical or socially inappropriate. This dual-mode functionality acknowledges the complex reality of mobility assistance needs, recognizing that users often require different levels and types of support depending on context rather than experiencing uniform mobility limitations across all situations and environments. The development of Dualcon Multi Supply Assistive Devices within an academic setting at Shih Chien University reflects the important role of design education in fostering innovative approaches to assistive technology, providing students with opportunities to engage deeply with user-centered design methodologies while addressing significant social challenges related to aging populations and mobility impairment. The six-month development timeline from July 2024 to January 2025 encompassed research into existing assistive device limitations, conceptual exploration of dual-functionality approaches, technical development of the connection system, ergonomic refinement of user interaction sequences, and validation of the design through prototyping and evaluation processes. The recognition of Dualcon Multi Supply Assistive Devices through the A' Design Award competition provides valuable validation of the design approach while contributing to the designer's professional development and establishing a foundation for potential further refinement and commercialization of the concept. The emphasis on simplifying operation while maintaining robust functionality reflects mature design thinking that balances technical sophistication with practical usability, ensuring that the benefits of dual-mode capability are accessible to users without imposing excessive complexity or operational burden. The integration of walker and scooter functionalities within Dualcon Multi Supply Assistive Devices also addresses spatial efficiency concerns, as users can store and transport a single device rather than managing multiple separate mobility aids, thereby reducing storage requirements in residential settings and simplifying transportation logistics when traveling or relocating between environments. The design contributes to ongoing evolution within the assistive technology field toward more adaptive, user-responsive solutions that acknowledge the dynamic nature of mobility needs rather than treating mobility impairment as a static condition requiring fixed interventions, thereby supporting greater independence, social participation, and quality of life for users across diverse contexts and activities.
