Frequently Asked Questions
FPrin | First Principles Based Engineering and Design
Q: What does First Principles Engineering mean at FPrin?
A. At FPrin, we approach engineering challenges by breaking problems down to their most fundamental elements, physics, materials, and mechanics, rather than relying on assumptions or analogies. This method reduces risk and leads to effective, cost- and time-efficient solutions tailored specifically to each project.
Q: What industries does FPrin work with?
A. We specialize in medical devices, especially systems that require precise motion, wearable technologies, drug delivery mechanisms, and complex sensing. Our clients range from startups to large med-tech manufacturers.
Q. How does FPrin support medical device innovation?
A. We help teams translate user needs into real-world solutions through knowledge-driven engineering, rigorous testing, and system modeling. Our work often includes prototyping, failure mode evaluation, and design feasibility for Class II and Class III medical devices.
Q. What types of systems has FPrin worked on?
A. We’ve engineered solutions such as:
- Wearable positive displacement pumps
- Pen-injector and Auto-injector design studies
- Dynamic low-pressure seal systems
- Occlusion detection and pressure sensors
- Needle and sensor insertion mechanisms
- Fluid flow interface controls
Each project is grounded in analytical modeling and verified by custom test setups.
Q. Can you help with early-stage product development?
A. Absolutely! We frequently work with early-stage development teams to objectively evaluate technical feasibility, explore design options and trade-space, and define robust test methods. Our focus on fundamentals makes us an ideal partner in concept validation and proof-of-principle phases.
Q. What makes your engineering services different from typical consultancies?
A. We go beyond CAD and prototyping. Our team builds analytical models, designs physical test apparatuses, and uncovers flaws in design direction before they become costly. Our philosophy is grounded in first principles—ensuring high-integrity, high-performance, and holistic solutions.
Q. How do you ensure reliability and manufacturability?
A. Our process involves predictive modeling, precision test rigs, and deep understanding of materials and tolerances. We identify failure modes early, optimize systems for robustness, and collaborate with development and manufacturing partners to handoff designs with confidence.
Q. Do you provide documentation for regulatory submissions?
A. Yes, our work supports regulatory documentation needs. We provide test data, risk assessments, and analytical rationale often used in FDA submissions, particularly in verification and validation stages.
Q. How does a project with FPrin typically begin?
A. We start with a conversation about your goals, challenges, constraints, and requirements. Then we scope a discovery or feasibility phase, followed by basic analysis. When we gain confidence in the design-direction, supported by data, we follow with more detailed analysis and modeling, iterative design, testing, and verification—customized to your stage of development.
Q. Where is FPrin located and do you work with clients remotely?
A. FPrin is based in San Jose, California and works with clients in the US and EU. We frequently collaborate remotely using digital tools, prototyping shipments, and cloud-based design and test reviews.
The FPrin way
Fprin offers “first principles” oriented, knowledge-driven design and engineering services to our clients. We deliver cost-effective innovation by leveraging computational methods and targeted testing to explore the design space and identify robust operating regimes. These tools enable cost-function driven optimization and Monte Carlo simulation.
We have demonstrated that this process results in will work designs that culminate in demonstration prototypes, supported by robust analysis, that are scalable, rather than can work, one-off, designs that may not be reproducible.
This helps the decisions makers:
Make informed design decisions based on data – not guesswork and hope. We simulate to refine the design and test to confirm the prediction and demonstrate the required function.
Finish the design process in an
efficient manner. You won’t be left wondering if there is a better design within the same constraints.
Brings design assurance which enables passing phase gates like EVT & DVT and confidently transferring into manufacturing.
