What it does
An assistive walking stick with an integrated grabber mechanism that allows elderly individuals and those with limited mobility to pick up dropped items without bending—enhancing safety, comfort, and everyday independence.
Your inspiration
The idea stemmed from observing how elderly individuals, particularly those using walking aids, often struggle to retrieve dropped items—sometimes leading to injuries or requiring assistance. Existing solutions like separate grabbers are often misplaced or not ergonomically integrated. We wanted to combine two essential functions—walking support and reach assistance—into one accessible product. This problem felt meaningful and aligned with both healthcare goals and real user needs.
How it works
This assistive walking stick features an integrated item retrieval system, allowing users to pick up dropped items without bending—ideal for the elderly or individuals with limited mobility. Two prototype versions were developed. The first includes a grabber with a rubber tip, magnet suction cup, and a trigger mechanism requiring minimal hand strength, supported by a hinged leg for added stability. The second uses a sliding dustpan and magnetic sweeper to collect items via a simple pull-handle system, making it lightweight and easy to use. Both designs were refined through iterative prototyping and user testing to ensure comfort, safety, and practical functionality. The final product promotes independence, reduces fall risk, and addresses common daily challenges with a simple, cost-effective solution.
Design process
The design process began with identifying a real-world problem: elderly individuals and walking stick users struggle to pick up dropped items, affecting independence and safety. Initial user and market research revealed a gap in existing solutions—most were either standalone grabbers or walking sticks with limited retrieval capabilities. Concepts were generated using functional analysis and a morphological chart. After screening and scoring, the team selected a concept that integrated a retrieval mechanism into a walking stick. Prototype Iteration 1 featured a scraper and conveyor mechanism powered by a Chebyshev linkage and hand crank. While functional, it was too heavy and complex for elderly users, leading to its discontinuation. Prototype 2A introduced a magnet-suction grabber with a trigger mechanism and hinged leg for stability. It improved usability and safety but was still mechanically intensive. Prototype 2B offered a simpler design using a sliding dustpan and magnetic sweeper. Though easier to use, its initial prototype was too heavy. Weight was reduced through CAD optimization and material changes. Each prototype was tested for usability, weight, and retrieval efficiency, with feedback guiding iterative refinements.
How it is different
What makes this design unique is its ability to retrieve flat items such as cards, paper, and coins—something most existing grabber-integrated walking sticks struggle with. Unlike other products that focus only on basic object retrieval or require separate tools, this design integrates a multi-functional retrieval system directly into the walking stick without compromising its primary function as a mobility aid. Two versions were developed: one with a magnet-suction grabber and trigger system for versatile pickup, and another with a sliding dustpan and magnetic sweeper for simple, low-effort operation. Both prioritize ergonomics, user comfort, and safety, especially for users with limited strength or dexterity. The design also focuses on stability during use, with hinged leg supports and intuitive controls. Its innovative yet practical features offer a balanced solution that enhances daily independence in ways other products do not.
Future plans
The next steps involve combining the best features from both prototypes to develop a third, more refined design. Key improvements will focus on further reducing weight, enhancing ergonomic comfort, and refining the retrieval mechanism for greater efficiency and ease of use. Continued user testing and feedback will guide iterations to ensure the product remains practical, intuitive, and user-centered. The ultimate goal is to create a lightweight, durable, and affordable assistive device that empowers users to perform daily tasks independently and safely.
