Application Characteristics
Application Requirements
Initially, all the OEM wanted was a light pipe solution for a device that included an intricate, eight-piece logo to communicate treatment status. Each piece could illuminate on its own, or work together in unison with the other logo elements. In addition to maintaining the same pattern with the complicated client logo, design requirements included:
- Reusing the existing tooling for the illuminated logo on the front panel
- Attaining maximum brightness for visibility by medical staff and patient during treatment
- Delivering uniform illumination, even along complex edges of the logo elements
“In many cases, the simpler a device looks on the outside, the more complicated it is on the inside.”

Solution/Approach
Our team decided to take a step back and look at the client’s design needs from a more holistic angle. We discovered we could not only provide the desired illumination and visual properties required but also optimize the existing design to save even more on production costs. Creating soft illumination throughout the intricate logo design required significant modeling to provide maximum brightness and uniformity along with a 150-degree viewing angle.
To test our concept, we provided a 3D prototype that was printed in our advanced design lab. Ultimately, VCC was able to create a more comprehensive solution that streamlined the client’s supply chain by providing a turnkey solution made up of:
- Light guide design, including simulations to determine how the light would perform
- Plastics manufacturing to produce the light guide
- PCB assembly
- Connecting internal components in house, including a backlit display, integrated card reader technology
- Adding wire harnesses
Our team ran simulations to determine the ideal angles, placement, and composition of the LEDs and other illuminated components to achieve the desired visual properties.

Custom PCB Assembly
- Incorporated a metal core for heat dissipation
- Simplified the shape of the board, resulting in significant savings on materials
- Used a white solder mask to improve efficiency by 5% over the industry standard black overlay
- Added connectors, wire harnesses and other components to the back of the PC board, saving manufacturing steps and costs
Once assembled, this multi-layer solution includes the front logo panel, light guide in the same shape as the logo, and white metal PCB core with a simplified shape.
“VCC took a simple component requirement and turned it into a comprehensive solution. Redesigning and manufacturing critical systems, our team reduced costs and TTM — while delivering a fresh, modern design!”
