About the Inventor - Robert Wajda

Once in a blue moon we as individuals come across someone in life who is always working on an exciting idea or project. Robert Wajda, inventor extraordinaire, is precisely this type of person.  Innovation and creative thinking drive Mr. Wajda towards a greater understanding of where the possibilities lie with future endeavors to improve the quality of life for everyday people. A thinking mind never turns off, and that’s exactly the method he approached in consideration of this very novel invention and its early beginnings. Problem solving never ceases to exist, even while we are asleep. When the human brain thinks about something on a consistent basis, realities begin to unfold. This may sound like lunacy to some, but only imagine that it is more common that you might think. Even as this project receives its Patent from the United States Patent and Trademark office (Pat. 11499760), Mr. Wajda has (3) additional energy efficient protects in the works. One of which already is already “Patent Pending” and another patent is forthcoming. 

Human ingenuity and dealing with the trial-and-error proceedings that is attached to such a title has led many people down paths of huge success. The business of entrepreneurship can be lucrative, and when combined with innovation provides a unique way to move forward with new and useful ideas constantly. Ingenuity does not stop with design but instead expands with the genuine passion of creativity, especially coupled with having fun.

Mr. Wajda has always been involved with drafting new ideas and considers this aspect of innovation an essential part of daily life. Early academic and apprenticeship training in mechanical and industrial drafting gave him a unique grasp on the techniques that many early 1900 patent renderings. Training in Computer Animated Design (CAD) helped hone Mr. Wajda’s skills in visualizing ideas in 3D moving into modern design and engineering.

Preference for Mr. Wadja will always rest with the old-school approach of using a drafting board with an attached machine arm, stencils, and French curves. Thick lead allows prominent lines to be drawn with an India ink finish that signifies all his drafts. This specialized form of drafting helped take this project to the next level, shaping it tangibly from the beginning. Even today, people study and refer to previous patent drawings for reference and detail. This will also ring true for years to come as future generations begin their quest in innovation.

Wajda Hand Drawings in India Ink

Technical design and a ‘thinking out of the box’ mentality will always remain a constant in central aspects of the innovation and manufacturing industry. Technology has improved allowing drafting to be accomplished digitally, but freehand techniques remain basically the same. Almost every great invention throughout time has been designed by hand with pen and paper. Drafting by hand allows better decision making through a slower pace that brings out the extremes of creativity. The visual perception of designing on a larger surface brings drawings up close allowing personal connections to be made instantaneously with the design at hand.

Exaggerated angles that are incorporated into specific techniques allow the design(s) to seemingly appear three-dimensional. This visual representation on paper is why artists and painters have worked from easels and flat drawing surfaces for hundreds of years. The quality of these early patented works are timeless masterpieces. Mr. Wadja’s niche of combining creative engineering that is geared towards art and constructive design displays the forte that is needed to expand the untapped potentialities of the HVAC market and industry. These drawings were allowed by the United States Patent and Trademark Office with no objections on the first try. 

Why is hand drafting a preferred method for you over CAD design, even in 2022?


I am one of the lucky ones that have extensively trained on both table drafting and CAD design. My drafting instructor 1985, Arthur Frederick, was a true master. I established a student/teacher apprenticeship under his direction for several years, and the ropes of the professional drafting trade were revealed to me through much patience and practice. I found my passion in the ‘old school’ approach of getting up close and personal with the project at hand.

Drafting by hand seems slow and error prone, why not make the full conversion to CAD?   

When I draft a project by hand the decision-making process is very slow. This allows more creative thought processes to flow in and out of freehand drafting. Of course, there are errors that will always occur when conceiving ideas with pen and paper. When graphic and CAD designers draw on a computer screen, the viewing space is flat and contained. You really can’t visualize a design that is internalized in the mind when working in 3D on a flat computer screen. At least for me it seems difficult.  

When drafting on a drawing board, I use large 18” x 24” vellum paper positioned at a 45-degree angle. The angle alone brings the drawing right up close to me. This visual perception allows creativity to flow where I can almost see the design(s) I am working with in my mind become 3D as I am drawing it tangibly on paper. Visual perception is key to why many artists and painters have worked from easels for hundreds of years.

What inspired you to excel in the field drafting and establish yourself as an entrepreneur?

As I examined and studied previous art of patent drawings of the past and present, I noticed distinct differences of the early 1900s renderings. Most of today’s draftsman create a “stick type drawing” and many can’t fraw on a board even after going through college. I immediately knew I wanted to draft my ideas ow they did in the early 20th century. I could almost feel the inventor going through the mental processes of drawing needed to create exceptional works. For me, thick straight lines provided real-life nostalgic looking drawings that bring out the best in my creativity. I feel the quality of these early patent drawings are masterpieces among themselves.  Being a master draftsman myself, I could look into the drawings of the late 1800s to early 1900s and visualize the ink strokes. I can see minor mistakes that were covered up. With ink, you only have one chance to get it right so you generally do the most difficult part first with lots of patients. 

Table drafting versus CAD development?

I like them both honestly. I spent months on the drawings seen here by creating them on large vellum paper and then reducing the images to standard 8.5 x 11.5 paper. I then placed them on my trace light board and transferred them by hand with India ink creating a final draft product. These final drafts depict masterful blueprints that can later be converted to CAD to produce beautiful 3D images. It is the methodical nature of drafting by hand that ultimately gives me the therapy of having fun at what I do. The most fulfilling part of the entire process is watching your product come to life right before your eyes.

What excites me the most is that 200 years from now, I already know someone will be studying these drawings as they are now a permenent part of history.
