Handheld Bladder Scanner
While legacy ultrasound platforms are optimized for the controlled environments of Tier 1 hospitals and urology clinics, the emerging home health and mobile nursing sectors present unique mechanical and ergonomic challenges. Traveling clinicians require a device that balances clinical-grade precision with extreme portability, durability, and intuitive "one-handed" operation.
I was tasked with spearheading the mechanical architecture for a new form factor designed specifically for this high-growth market. My focus was on translating complex human-factors data into a ruggedized, lightweight enclosure that maintains the brand’s signature reliability while meeting the rigorous demands of mobile medical environments.
Starting out
I spearheaded the transition from initial industrial design (ID) concepts to high-fidelity physical prototypes. Working from 2D aesthetic sketches, I developed robust 3D master models in SolidWorks, ensuring that the stylistic vision was balanced with internal mechanical constraints, such as PCB clearances and battery architecture.
To facilitate rapid user-testing cycles, I managed the in-house additive manufacturing process, utilizing SLA (Stereolithography) printing to produce high-resolution prototypes. These models allowed for immediate tactile feedback on grip ergonomics and control placement, enabling us to iterate on the form factor with a level of precision that 2D sketches could not provide.
To ensure a high-confidence final architecture, I led an intensive down-selection process involving over 15 unique form-factor iterations. While several initial concepts were eliminated due to identified "pressure points" or non-intuitive control mapping, these failures were critical data points that informed the subsequent design phases.
I acted as the primary bridge between clinical feedback and mechanical execution. By synthesizing qualitative data from nurse interviews into "hard" CAD geometry, I developed a series of refined prototypes that prioritized neutral wrist posters and intuitive "blind-reach" button placement. This iterative cycle resulted in a final form factor that achieved high user-acceptance scores and provided a natural, secure grip for a wide range of hand percentiles.
Refinement
Through systematic user-preference mapping, a clear ergonomic "winning" architecture emerged: a vertical orientation with a contoured grip inspired by high-duty-cycle kitchen immersion blenders. I leveraged this cross-industry benchmark to create an inspiration board, identifying specific geometric patterns and "power-grip" features that translate to reduced hand strain during extended clinical use.
To validate this refined concept, I partnered with the Marketing and Clinical teams to conduct in-situ user research. By observing nurses within their actual workflows—navigating confined spaces and varying patient positions—I gathered high-fidelity qualitative data that laboratory testing alone could not provide. This field-driven approach ensured that the final mechanical design was not just ergonomically sound in theory, but highly functional in the rigors of real-world home health environments.
Data Analysis
Translating field research into actionable engineering requirements required a sophisticated approach to design communication. I synthesized complex qualitative feedback from clinical users into high-impact data visualizations and comparative charts for cross-functional stakeholders, including Marketing, Engineering leadership, and Executive Management.
By utilizing Tableau to summarize data of user-preference trends, I provided the empirical evidence needed to de-risk the project’s direction. These visualizations served as the "single source of truth" during critical design reviews, ensuring that high-level architectural decisions were grounded in verified user needs rather than subjective preference. This level of transparency was essential for maintaining project momentum and securing executive alignment on the final product path.
Result
The culmination of this iterative process was a high-fidelity mechanical architecture that harmonized complex ergonomic requirements with rigorous Design for Manufacturing (DFM) standards. I led the final engineering refinement of the external housings, ensuring that every draft angle, wall thickness, and parting line was optimized for high-volume injection molding.
A critical aspect of this phase was protecting the "design intent" during the transition to production. While internal component placement required strategic modification to accommodate tooling constraints, I successfully preserved the validated grip contours and tactile features that had achieved peak user-acceptance scores. The final result was a sophisticated, manufacturable probe assembly that balanced premium industrial design with the technical reliability required for a next-generation medical diagnostic platform.
