Product design and quality

Product Design

The product design has been iterated upon revision after revision, with quality a constant focus. This has been made possible due to improvements in manufacturing technology that allows prototypes to be produced faster than ever before. Examples of this include 3D printers such as those from Form Labs (http://www.formlabs.com) based in Massachusetts. Personal CNCs such that those made by Carbide 3D (http://www.carbide3d.com) based in California have been game changers.

Examples of how these technologies have been used is the flush integration of the lens the case. A high quality optical grade material can be inexpensively produced with high precision allowing a smooth flush mounting. This simply wouldn’t be possible historically without forcing either a high manufacturing cost or moving directly to high volume forcing a greater expense. The focus on rapid iteration has allowed feedback received from users to directly and nearly immediately improve the product.

Dealing with power and heat

With respect to red and blue light therapy devices, one of the challenges has been the power required. This causes issues both in regards to the supply of power but also heat dissipation. While it would be easy to solve the power issue by simply plugging in the RejuvULite, this is undesireable as it really doesn’t support a busy lifestyle. Who likes to be tethered to a wall in 2020?There is also the convenience factor as there may not be an outlet in a convenient place, such as walk-in closets. The heat dissipation problem is the other issue. If the product is not using extremely efficient switching regulators and power converting electronics, it will get hot. The combined desire to only use two AA batteries and extremely efficient design required many revisions of the circuitry.

The product has been made what it is today by rapidly iterating and integrating feedback for continuous improvement.
