Inventions are the cornerstone of growth; together with countless patents, they constitute discoveries that shape our world. However, some of the existing patents are ridiculously innovative, impractical, and otherwise totally unnecessary, leaving our team shaking our heads in disbelief.

The mentioned alleged “dense patent” may lack utility, although it helps them as a will to have boundless imagination. Welcome to a universe of some of the far-fetched inventions that somehow made it past the patent office.

Anti-Eating Face Mask (US4344424A)

Is your mouth always open because you are constantly eating, causing your weight to make you feel like a giant? Don’t worry—someone has invented a “mouth jail” just for you! This device ensures you’ll never open your mouth again unless detached. It also serves as a solution for those who talk too much, making it a multipurpose tool.

Filed in 1982, the Anti-Eating Face Mask is a device designed to help individuals resist the temptation to overeat. The mask is designed to cover the mouth, physically preventing food consumption while it is worn. It is secured around the head with straps, making it difficult to remove casually, thereby reinforcing the wearer’s commitment to avoiding food.

Bird Diaper (US5934226A)

If having a bird locked in a cage without it soaring high and being free wasn’t enough, this person did not want his interior brain and exterior matching with trash. So, to solve the dilemma for the exterior, he invented a bird diaper so that the bird could not excrete on his problems like the world. This invention consists of a small, adjustable harness that fits snugly around the bird’s body, coupled with a detachable, absorbent diaper.

The design aims to collect droppings efficiently without causing discomfort to the bird. Indeed, it is a genuine problem for bird owners to provide their pets with the freedom to fly around the house, but the process of training to wear such an accessory is, as the old saying goes, easier said than done. It is well known that birds habitually dislike being put on unknown objects, and the training to make them adapt to a diaper can be very time-consuming as well as stressful for both the owner and the pet.

Motorized Ice Cream Cone (US5971829A)

For all the lazy ice cream lovers out there, there's now a solution to the “effort” of licking the ice cream! The ice cream that moves while you eat! Motorized Ice Cream Cone is the one that makes enthusiasts exist in an indulging environment and at the same time be free of work. Aiming at optimizing customer experience, this new mobile power tech has a slim and ergonomic model that spins ice cream as smooth as for you to have a smile from ear to ear.

There is a quiet, rechargeable motor incorporated in the center of the cone that smoothly spins the ice cream and thus keeps it at the ideal angle, so you do not have to get your hands off the wheels. To enhance the experience, this new version includes adjustable speed settings, allowing users to customize the spin based on preference—faster for a quicker treat or slower for savouring every moment.

It also features a built-in drip guard that prevents mess and maintains a clean eating experience. The cone is made from eco-friendly materials, and the device is easily washable, ensuring it’s both fun and functional. Ideal for those who enjoy their ice cream more passively, the Motorized Ice Cream Cone 2.0 can become your new favourite gadget—because why should enjoying ice cream require effort?

The Air-Conditioned Shoe (US20050060906A1)

No longer will you have to, thanks to the Air-Conditioned Shoe, which is the very next level of comfort and freshness for your feet!
