Simplifying the complex with engineering excellence

San Diego Engineering Design Services

Design

With any new mechanical engineering assignment, our creative brainstorming and ideation is where the fun begins. At Simplexity, we start concept generation in a distinctive manner. This kickoff, an essential part of our design process, has proven over decades to deliver the simplest, most effective product engineering results possible.

How do we do it? We start with the big picture. Our mechanical engineering team kick-off is a creative, blue-sky kind of place. Everything’s on the table; the scope, the paradigms, the traditional and not-so-traditional engineering choices By beginning the project from a systems perspective, we can question assumptions and brainstorm solutions that would not be possible by looking at things piecemeal We identify the most challenging aspects and dig in. If a feasibility study is called for we identify it right away. Next, we’re relentless in drilling down to identify the most challenging, highest-risk areas of the project. The best ideas that come out of this process are honed and refined into a system architecture that delivers the most successful product possible.

Beyond efficiency, how does this approach help our clients? Just one example – on rare occasions an intractable problem will halt a project; if that happens, we deliver the news you need as fast as possible. With our design process itself engineered to deliver what’s best for you, we spend as little money as possible proving the concept will work, saving the more routine design challenges for later, once risks are minimized.

Once risks are understood, we dive into the details with our full-service team to deliver the next milestone. Our services are comprehensive, meeting your engineering design needs in every discipline: mechanical, electrical, firmware, software, and manufacturing.

Detail design is where thousands of mechanical engineering decisions turn ideas into a reality. Each feature of every part has a distinct function and can be designed an infinite number of ways. Simplexity engineers put their experience to work every day; performing calculations to simplify problems and determine the best feature sets necessary to create a reliable product.

When Hewlett Packard approached us recently, they had a bold new idea for a consumer color printer attractive enough to please the most design-conscious buyers. Read our HP Envy case study to see how our design engineers made this concept a best-selling reality.
