Chapter 4: Selection Algorithm – Six Steps to Find Your Perfect Ramp

Step 1: Parameterize Your Needs

Maximum Height Difference: Measure the largest vertical obstacle encountered regularly

Available Space: Length restrictions of the area where the ramp will be placed

Frequency of Use: Daily use or occasional use

Transport Conditions: Car trunk size, feasibility of carrying on public transportation

Step 2: Slope Calculation Model

Safety Slope Formula: Length = height difference × 12 (standard) to × 20 (ideal)

Example: A 15cm step requires a 1.8-meter (standard) to 3-meter (comfortable) ramp

Power Wheelchair Adjustment: Slope should be reduced by 20% compared to manual wheelchairs

Step 3: Prioritize Functions

Core Needs: Safe load-bearing capacity, reliable slip resistance

Important Needs: Weight, storage dimensions

Additional Needs: Appearance, extra functions

Shifts in Social Perception

From "special needs" to "universal design"

From "fixed facilities" to "mobile solutions"

From "medical aids" to "daily life tools"

The development of portable wheelchair ramps symbolizes a crucial social progress: accessibility is no longer merely a requirement of building codes, but a personal capability that can be carried anywhere. These sophisticated aluminum alloy or composite structures may fold down to the size of a suitcase, yet unfold to overcome height differences of tens of centimeters—this is not only a triumph of technology, but also a tangible manifestation of social inclusion.

The process of selecting and using a portable ramp is a profound empowering experience. It means users no longer need to pre-investigate the accessibility of every destination, no longer have to abandon trips because of unknown steps, and no longer have to be the "person requiring special arrangements" in social events. With a ramp in hand, the road ahead is free.

In the future, with advances in materials science and smart technology, portable ramps are likely to become even lighter, smarter, and more versatile. But no matter how technology evolves, its core mission will remain unchanged: to reconnect paths that should have been connected but were interrupted, allowing everyone to transition smoothly and move forward with confidence. In this sense, every portable ramp is a mobile bridge—not only crossing physical barriers, but also linking the two banks of equality and dignity.
