Project description

ElvaX Jewelry Lab - mini-laboratory for high-precision analysis of precious metals and jewelry. The measurement process takes only a few seconds. The result is displayed in both percentages and carats. ElvaX Jewelry Lab is also able to detect coatings and non-standard alloys. This tool can be used either with a built-in computer with a high-resolution touch screen or with a PC with ElvaX software installed.

The main requirement of the customer is to design a case for a spectral desktop analyzer, which could be used both in laboratories and in jewelry stores. The case was to isolate harmful radiation, be safe during operation, as well the most convenient to use.

We wanted to make the building in a minimalist style, which would best fit the scenario of using this mini-laboratory for the analysis of metals and alloys. At the same time, it was necessary to keep the simplicity of the whole model, so as not to increase the cost of manufacturing the case due to its dimensions and due to the complexity of the design. Much attention was paid to the ergonomics of the device.

The main difficulties that the team faced during the development of this project:

1. Design large parts with smooth surfaces in such a way as to avoid defects in injection molding. This is a simple task for engineers, but it requires a certain level of expertise in the field and special care for undefined development. Rapid prototyping technology does not allow the detection of errors of this type, so all parts of the case are checked several times to eliminate all risks before we receive the first industrial design.

2. Combining ready-made mechanical assemblies of metal together with plastic body parts. The nomenclature of parts consisted of standard metal fasteners, plates, corners, elevators, and plastic transparent and opaque body parts. Designing a complete assembly in CAD meant fitting all such components and electronics to the body parts, taking into account the mechanical properties of each of them.

3. Placement of the analyzer device and its protection against radiation.

This was essential for the safe operation of the device. To do this, it was necessary to build a special insulating screen around the chamber, where the spectral analysis takes place. Due to the fact that we provide prototyping services for each project, we were able to quickly check the geometry of this camera with insulation undefined body parts, as well as internal spaces for ready-made mechanical components, touch screen, and mini-printer for printing analytical certificates, which is also included in the configuration of the future device.

4. Color scheme of the device and calibration of white color in mass production.

When developing the basic model, a white glossy version of the case was chosen. Later, during the production of different batches at different time intervals, we encountered a mismatch between the white color/shade of the plastic, which rejected a certain amount of castings. It was possible to achieve the correct shade through several trial castings. Later, for marketing and production reasons, it was decided to develop several more color schemes for sale in other regions.

The team spent 1.5 years implementing the project. undefined
