Rainy, windy conditions can quickly turn a traditional umbrella inside out. But what if I could create a shield of air strong enough to push raindrops away before they ever touch me? That’s the idea behind my unpatented invention: a powerful “air umbrella” in the shape of a simple stick. To be fair, I live in Vancouver, BC and it rains so much I just got used to using a hood instead of an umbrella most of the time. But when I first moved here, I had an umbrella turned inside out about once a month. Below, I dive into how it would work and the challenges that stand in its way.
1. The Idea: An Air-Powered Shield
Concept Overview
Imagine holding a slender device—similar to an umbrella handle—that draws in air from an intake at the bottom (an intake with a water shield so it pulls up dry air). This device then expels a powerful upward blast of air, blowing raindrops aside.
Why It’s Appealing
Unlike a traditional umbrella, there’s no canopy to invert during high winds. Plus, it offers a futuristic, hands-free feel to battling the elements.
2. How It Would Work
Air Intake and Exhaust
My invention would pull air through a protected opening near the base. A fan or blower mechanism inside the handle would propel the air upward, creating a continuous shield.
Keeping Dry
Raindrops would be displaced as they encounter the concentrated column of air, much like a personal force field. The result? Fewer droplets reaching my head and shoulders.
3. Key Challenges
Power Source
Generating a strong airflow would demand significant energy. Batteries in the handle must be lightweight yet powerful enough to run for a reasonable duration.
Energy Density
Today’s batteries may be too heavy or short-lived to sustain the airflow needed. Technological advances in battery design or alternative power sources might be required before the device is truly feasible. I don’t think energy density will become high enough during the patent term (had I received a patent) to make the device practicable. I hope I’m wrong!
4. Why I Never Patented It
Exploring Feasibility
Practical hurdles—like energy efficiency and device weight—kept this invention as a fun thought experiment rather than a commercial product.
Open Invitation
I didn’t file a patent or build a prototype, so the idea remains open for others to refine or pursue. In a way, it’s an invitation to dream big and solve complex technical challenges.
5. Embracing Innovation, Rain or Shine
Whether it’s perfecting a futuristic rain-deflection stick or brainstorming other “think different” solutions, I believe creative thinking can reshape everyday problems. Even if my concepts never become commercial products, sharing them can inspire others and spark new directions for innovation.
