MeCHENATECH
In this project the client wanted to validate the design before the start of the verification testing.
Therefore, to confirm the design, all the test cases per standard was simulated using finite element analysis.
Based on the results design change recommendations were provided to the client.

This mechanism is used in the manufacturing process of
Concentrated Photovoltaic (CPV) module. The machine transfers
the module from first manufacturing station to the next by
disengaging the module from the fixture, lifting, rotating,
and setting it on the stands. This project was relatively
more complex since it involved multiple disciplines.
The first two functions, disengagement and lift, were achieved
by pneumatic actuation. The rest of the process was done using an
Electric gear drive and appropriate sensors.
A combination of proximity and limit switches were used to
accomplish the desired functionality as well as safety.

Cosmetic and personal care market is one of the largest industries in the world growing tremendously
every year therefore designing a product to be able to compete in this market is a challenging task.
Requirement development became a dynamic process to encompass gradual understanding of the
market and to consider all the use cases. After finalizing initial requirement document and
understanding the constraints, we started the design of the prototype that included mechanical,
electrical, firmware, and aesthetic design with ergonomic aspects. The device consists of many off the
shelf components such as: motors, pumps, fans, level sensors, limit switches, buttons, and LEDs.
In a short time, the first functional prototype was created then the device was put to test and reviewed
by consumers and industry leaders to better understand the improvement opportunities.
Currently in the pilot production phase, the prototype has been redesigned to overcome the challenges,
enhance its functionality, and design for manufacturability with extra attention to cost and time
functions. Supply chain, product life cycle management, and assembly line test and configuration is
being developed to support high quantity manufacturing.
The production phase will consist of setup unit accelerated life test with custom firmware and software
to find failures in short amount of time. Setup assembly line test equipment to ensure sample units are
tested and ready to be delivered to customers.
During the prototype processes we developed intellectual property for our client and helped in filling
patent for the device unique functionalities and innovative dual axis mechanism.
On the mechanical section we faced with designing rotational and vertical motions incorporated in a
single mechanism and to be robust, cost effective, and easily manufactured and assembled. We had to
innovate this complex yet simple mechanism that is filed in the patent.
The device consists of many components that need to be operating with respect to each other and
inhibit any system and user failures. To accomplish this coordination, a comprehensive and modular
state machine was designed then implemented in the firmware that enabled us to have flexibility and
respond quickly with dynamic changes of functionalities.
After market research and determining the trend in present and future of electric vehicles market, we
collaborated with our client to draft the most comprehensive requirement document to cover various
configurations.
The system is capable to control and monitor power output of up to 17KW with input of 240V AC single
phase. The system consists of ground fault protection, latched relay detection, temperature monitor,
over current/voltage sense, and pilot signal monitor and control to communicate with the vehicle.
The finished device has an aesthetic and functional design. The plastic enclosure was designed to
feature status indicating multi-color LED, tamper resistance internal enclosure, convenient wire
connections, and simple and secure wall mounting fixtures for installation.
In order to simplify and reduce the time to assemble each unit, some of the electronic components had
to be custom designed, internal wire routing and boards placements had to be studied and modeled to
ensure efficiency.
From initial market analysis we found out that its essential to meet various demands of power delivery
and be able to expand on our current design. To meet this objective a unique configuration was
developed with careful placements of circuitries to enable flexibility and future enhancements based on
market direction.
Lighting systems are essential part of any professional photography sessions and it’s vital for companies
to have the proper infrastructure to be able to adapt quickly to any future technology advances in
lighting systems.
To assist the client with setting up the necessary foundation, the fixtures were redesigned for efficient
manufacturability and ease of future modifications. Part of the project was to digitalize all the existing
2D sketches and convert them to 3D models with proper 2D drawings. During this process all the
components were transferred to our internal life cycle management system with part numbers and
revision control for traceability and expedient future modifications.
In an assembly line every station is critical to producing final high quality and cost-effective product.
Press fitting metal parts is a common assembly process is all industries.
The objective of this project was to design a new die capable of pressing multiple joints at the same time
for an existing hydraulic press.
The first step was to estimate the press force required per each joint to achieve this Finite Element
Analysis (FEA) was performed to simulate the process. Based on the outcome of simulation and the
tonnage of the press the maximum number of joints that can be simultaneously pressed was calculated.
In the next step the die was designed to evenly distribute the press force among all the joints. This
functionality was verified by FEA.
Designing a robust and low-cost solution to meet clients’ requirements was a challenging task that we
were able to overcome by iterative design and analysis cycle alongside working with outside shops for
cost effective fabrication.
Engineering design is an iterative process to identify the problem and the constraints, conduct background research,
collect all the requirements, develop possible solution, build a prototype, test and evaluate the prototype.
