Meera Ramaswami, inspired by her grandmother's fall while exiting a car in Ann Arbor, developed Cargility, a portable mobility aid that helps people enter and exit vehicles safely. Starting in 2022, Meera designed and tested prototypes of the device, which engages with a vehicle’s doorframe to provide stable support for users, reducing fall risk and strain on caregivers. The invention earned recognition at The Henry Ford's Invention Convention and secured a US utility patent; it is now being developed by Cargility, a company co-founded by Meera and her mother Praveena Ramaswami.

same event (that is the story summary below).
A fall while getting out of a car changed the direction of Meera Ramaswami’s life.
asserted
fall → get → life
She watched her grandmother lose her balance during a moment that should have been routine, then saw the injury heal while the fear remained.
asserted
fear → watch → moment
Her grandmother became less willing to travel, and Meera began thinking about how a small loss of stability could lead to isolation and lost independence.
uncertain
loss → become → independence
That question eventually became Cargility, an Ann Arbor company developing a portable mobility aid that helps people enter and exit vehicles safely.
asserted
people → become → vehicles
Meera designed the device, tested prototypes, earned recognition through The Henry Ford’s Invention Convention and secured a US utility patent.
asserted
Meera → design → patent
As reported by The Henry Ford and Ann Arbor SPARK, the invention has grown from a family experience into a company founded by Meera and her mother, Praveena Ramaswami.
asserted
invention → report → Meera
A familiar moment with serious consequencesGetting into or out of a car is an ordinary action for most people, but it can become difficult after an injury, during ageing or for anyone with balance and mobility challenges.
asserted
it → become → challenges
A person may need to twist, lower themselves, find a stable surface and stand on uneven ground, all while managing the distance between the seat and pavement.
uncertain
person → need → seat
For Meera’s grandmother, that moment led to a fall.
asserted
moment → lead → fall
The physical injury eventually healed, but the emotional effect lasted longer.
asserted
effect → heal → ?
Fear of falling again changed how willing she was to leave home.
asserted
she → fall → home
A simple vehicle transfer became a barrier to travel, social connection and independence.
asserted
transfer → become → travel
Meera recognised that the problem was larger than one family.
asserted
problem → recognise → family
Older adults, people recovering from surgery or rehabilitation, people with disabilities and caregivers may all face difficulties during vehicle entry and exit.
uncertain
adults → recover → entry
Existing solutions such as walking frames, canes or assistance from another person may not be convenient in the narrow space beside a car.
uncertain
solutions → exist → car
Observation to design Meera began developing the concept in 2022, using a process of observation, prototyping and testing.
asserted
Observation → design → observation
She didn’t start with an abstract engineering problem, but rather looked at a specific moment in everyday life and asked what kind of support would make it safer.
asserted
it → start → support
The device needed to be portable, strong and compatible with different passenger vehicles.
asserted
device → need → vehicles
It also had to be easy enough for a user or caregiver to position without complicated installation.
asserted
user → have → installation
A support that worked only in one type of car would have limited value, so adaptability became an important part of the design.
asserted
adaptability → work → design
The resulting product, Cargility, is a door to floor mobility assistive device.
asserted
product → result → floor
It engages with the striker in a vehicle’s doorframe and creates a stable support point.
asserted
It → engage → point
An articulating leg reaches the ground, allowing the user to lean on a railing while entering or exiting the vehicle.
asserted
user → articulate → vehicle
The design is intended to reduce fall risk and ease the physical strain placed on caregivers.
asserted
design → intend → caregivers
It provides a fixed point of support during the transfer rather than requiring a person to rely on a moving car door or another individual’s strength.
asserted
It → provide → door
How the device worksThe Cargility tool is designed to connect with the striker plate, the metal component in the vehicle doorframe that receives the door latch.
asserted
that → worksThe → latch
Once engaged, the device holds a stable relationship to the vehicle.
asserted
device → engage → vehicle
Its articulating leg consists of two members connected by a pivot, so that the structure can accommodate various vehicle heights and configurations.
asserted
structure → articulate → heights
When positioned correctly, the leg reaches the ground and supports a handrail or bar that the user can hold.
asserted
user → position → that
The aim is to create a continuous point of stability between the vehicle and the ground.
asserted
aim → create → vehicle
A person can use the rail while lowering into the seat or standing up, reducing the need to twist quickly or search for something to grip.
asserted
person → use → something
The tool is not intended to replace a doctor, physical therapist or properly prescribed mobility aid.
asserted
tool → intend → doctor
Its purpose is to make one specific part of everyday movement safer and more manageable.
asserted
part → make → movement
The device would still need to be attached correctly and users need to follow the instructions before they can rely on it.
asserted
they → need → it
Testing and refining the invention
Developing the first concept was only the beginning.
asserted
Developing → test → concept
Meera tested different designs and compared their performance.
asserted
Meera → test → performance
Earlier descriptions of her work indicate that she created possible models, evaluated them and selected the design that performed best.
asserted
that → indicate → design
A promising idea may fail when exposed to weight, movement, different surfaces or different vehicle shapes.
uncertain
idea → fail → weight
Prototypes expose weaknesses that aren’t apparent on paper.
asserted
that → expose → paper
Meera’s work also involved a balancing act between conflicting requirements.
asserted
work → involve → requirements
