Sure Hold
A Electric Rollator For Poeple With Limited Mobility And Reduced Grip Strength
Concept
The "Sure Hold" smart walking aid is designed for people with limited leg mobility and weak grip strength. Traditional walkers require hand strength to move forward, which is challenging for users with weak hands. Therefore, I designed this smart walking aid to enable users to carry out daily activities independently through smart technology and user-friendly design, improving their quality of life.
Background
Globally, people with leg impairments and weak hand strength due to certain diseases and injuries suffer from decreased quality of life because the market lacks walking aids suited for their conditions. These individuals cannot independently operate standard walkers due to insufficient hand strength. As the prevalence of these conditions rises worldwide, the demand for appropriate assistive walking devices is growing stronger.
Research
People with limited leg mobility and weak grip strength
Diseases and injuries can cause limited leg mobility and weak grip strength, and without suitable walking aids, daily life will be affected.
Caused by diseases
Arthritis
Muscle Diseases
Caused accidental injuries
Fractures
Tendon Tear
Neurological Disorders
Joint Sprain
Data Of Disease
The large number and growing trend of these diseases show that many people have leg mobility issues and weak grip strength.
Problems with Existing Rollators
Market Research
They are not suitable for people with weak grip; it's difficult to push the walker independently, so assistance is needed.

They lack monitoring and anti-tip features, so they can't support users to prevent falls when unstable.
Global Rollator Walker Market Size by Year (2024-2029)
This indicates a steady expansion trend and increasing demand for rollator walkers in future 5 years.
Development
Concept 1
Stable design but takes up a lot of storage space.
Concept 2
Handles are unsuitable, and the overall structure is unstable.
I choose concept 3 for its comfort handles, stability, easy storage, and suitability for people with weak grip and limited mobility
Concept 3
Safe grip handles, stable struture, and easy to store.
For final concept, I develop an interactive screen that aligns with the perspective of a standing person, a comfortable grip supports hand, the function of walking and sitting on same side and efficient storage.
Main Functions
Walking Mode
Sitting Mode
Interactive Screen
The curved screen optimizes viewing angles and features an interface with voice and manual controls for easier interaction.
Efficient Storage
This rollator is easy to store and can be folded, saving space when not in use.
Walking and Sitting in same side
The walking and sitting positions are on the same side, reducing the risk of falls when switching modes.
Ergonomic Handles
The ergonomic handle offers comfortable hand support while walking , helping users better exert force and control the walker.
Usage Steps
The user turns on the device and checks the features on the main screen.
The user prepares to start walking in the park and manually adjusts the environment settings and assistance level.
The user selects automatic mode, and the device adjusts the assistance level based on the uphill, outdoor setting, and grip strength.
The user uses the voice navigation function in the park to reach the destination.
The user can view detailed gait analysis reports while walking to help prevent falls and then arrive at their destination to meet friends.
