Problem:

This project was designed based on the clients request, it will be used by field personnel of the Comisión Federal de Electricidad (CFE). Its purpose is to facilitate the inspection of equipment and supply lines, which can now be supervised from the ground using advanced thermal detection technology.

While there are existing mobile devices with built-in thermal cameras, they lack the precision offered by specialized thermal cameras.

Process:

To ensure that the design of the Eskua20 equipment met the needs of CFE field personnel and provided an intuitive user experience, a user-centered design approach was employed. The following steps were taken during the design process:

User Research: Extensive research was conducted to understand the requirements, challenges, and preferences of field personnel at the Comisión Federal de Electricidad. This involved interviews and observations to gather insights into their workflow, equipment inspection procedures, and pain points.

Prototyping: Prototypes were created to test the use, functionality, and interaction of the product. These early-stage designs were tested and iterated upon to ensure a seamless user experience and address any usability issues.

Iterative Design Process: The design process followed an iterative approach, with continuous feedback loops and revisions based on user input. This allowed for incremental improvements and ensured that the final design met the specific needs of field personnel.

By employing a user-centered design approach, the Eskua20 equipment was tailored to the specific requirements and preferences of field personnel. This approach resulted in a design that prioritizes usability, functionality, and ease of use, ultimately enhancing the inspection process for field personnel at the CFE.

Solution:

The equipment consists of a case that incorporates a high-end mobile phone and a compact thermal camera. This housing provides unity, portability, and security to the electronic components.

éskua20 is designed with convenience in mind. It features an internal mini-PCB that allows the cellphone's battery to be powered without disconnecting the camera. This design also safeguards the equipment against voltage variations during battery charging.

To facilitate handling and transportation, an ergonomic handle is included, along with a carabiner that allows the equipment to be conveniently attached to the operator's belt.

The bottom part of the housing, where the camera is placed, is equipped with a cap holder, ensuring the lens cap can be securely stored while conducting thermal measurements. To ensure durability in harsh field conditions, everything is packaged in a sturdy case.

Overall, this equipment combines functionality, convenience, and durability, making it ideal for use in challenging environments.

Reflections:

We didn’t fail- we just found 100 ways that didn’t work. In the initial stages of this project, a significant portion of our resources was allocated towards developing an electronic system to establish seamless connectivity among the camera components. However, upon careful consideration, we made the collective decision to forgo the electronic system in favor of a more scalable and simplified version. While it was a challenging decision for the team, it ultimately proved to be the right choice, resulting in a more efficient and effective solution.
