Dell, a longtime leader in technology and the fast production of hardware and software that provide quality products for businesses and consumers alike, recently sought ideation and creative brainstorming for a new project. This project aimed to generate multiple concepts for a convertible-type computing device that would be larger than a traditional smartphone, but different from typical tablet devices and other convertible products currently on the market. Porticos, a product design and product development engineering consulting firm in Morrisville, NC, held multiple brainstorming sessions with Dell, which resulted in more than 14 concept designs being picked for further refinement to create the final product.
Brainstorming and Concept Development in Support of Product Differentiation
Porticos’s hardware engineers were requested to generate multiple concepts for a convertible-type computing device by Dell, that would be larger than a traditional smartphone, but different from typical tablet PC devices or other convertible products currently on the market. There was emphasis placed on developing concepts for a differentiated input method, and convertibility for multiple use cases and configurations.
To accomplish the requirements from Dell in the quick, efficient way that Porticos’ hardware engineers work in, they held multiple brainstorming sessions that generated more than 14 concept designs. These concept designs were then reviewed with Dell, to make sure all parties were aware and on board with down selection and refinement. Then, the selected concepts were refined, and Porticos’ hardware engineers worked with partners of Porticos to create highly cosmetic prototypes that Dell used to conduct internal reviews and user studies.
Porticos is proud to have partnered with Dell on this project, and to have once again had a hand in driving new, innovative technology into the hands of businesses and consumers. Our hardware engineers’ commitment to fast, quality work and ensuring the needs of our partners are consistently and throughly met every time they are requested to work with another company is how we reiterate our love for technology and innovation.
Porticos, a product design and product development engineering consulting firm in Morrisville, NC, continues to revolutionize in the world of hardware engineering and innovative technology development. One of Porticos’ most innovative projects to date is their involvement in the development of a rugged pistol grip.
Symbol Technologies, an American manufacturer and worldwide supplier of mobile data capture and delivery equipment, headquartered in Holtsville, NY, is currently a subsidiary of Zebra Technologies (Lincolnshire, IL). When Symbol Technologies came to Porticos’ hardware engineers, the pistol grip accessory proved to be an engineering and concept modeling challenge. It was a challenge Porticos was excited to meet and execute, as well as a project that remained in line with Porticos’ area of expertise.
Mechanical Concept Design
In order to most effectively create the ergonomic geometry required for the rugged pistol grip, a high-proficiency pro engineer was necessary. From an engineering perspective, it was essential for the pistol grip to pass the rugged testing that Symbol Technologies’ products have a reputation for.
In addition to the necessity to pass a ruggedness test, the interface to the main unit had to simple yet secure, while also accommodating the large number of critical interfaces. Porticos’ hardware engineers provided all of the mechanical design concept and executed the development of this product, all the way up to the successful transition to the production manufacturing source.
Porticos is proud to be part of such an innovative, essential project, and continues to shrive to create forward-thinking technology that will make as much of a mark in 40 years as it does today.
Symbol Technologies was ultimately satisfied with the concept design and execution of the rugged pistol grip, and it is currently being used in today’s market. Porticos’ hardware engineers was happy to collaborate with Symbol Technologies and offer up their expertise to ensure the production of the product was what would best suit consumers and the company overall.
Porticos and Device Solutions worked closely to optimize placement efficiency to create the smallest BioMedical system package possible. This was especially important for both units because power consumption needs to support a 30-day transmission period, which is provided by a large battery cell.
Ambulatory ECG Monitoring System Product Development
BioMedical Systems (now part of ERT), has been providing medical data analysis and support for physicians and their patients for nearly 40 years. They saw a need for a mobile cardiac telemetry system that could take advantage of their sophisticated arrhythmia analysis software, record the data and transmit that information in real time to a group of certified cardiac technicians. To make their vision a reality, they came to Porticos and Device Solutions—one of Porticos’ partners—who experienced in hardware and software development for wireless devices. Herein, the TruVue™ product was born.
The TruVue™ system consists of a patient-worn ECG recording device, a hand-held device that receives and analyzes the information from the recording device. The device then transmits the real-time data to the BioMedical Systems headquarters in St. Louis, where the data is analyzed further and formatted for easy access by the physician.
Porticos’ hardware engineers created the 3D CAD data using Unigraphics software. Bluetooth was chosen as the wireless communication protocol between the patient-worn device and the hand-held device, while GSM-based-cellular was used to transmit between the hand-held and the cardiac center.
In order to minimize detuning of the chip antenna in the patient-worn device, snap features were incorporated into the PC/ABS housings to limit the need for metal assembly hardware. FEA was conducted in Ansys to ensure snap features would remain secure during normal use and drop scenarios.
One of the unique features for the hand-held was the keypad. In order to support the user interface and reduce confusion to the patient, the keys had to be individually backlit and, at the same time, isolated from the surrounding keys. This way, as the menu options changes on the display, only the keys applicable for those options would be lit. The result is deceptively simple-looking keypad, that integrates mechanical and software user interface to create an intuitive and positive experience for the patient.
Hardware Production Results
Thanks to the hard work of Porticos and Device Solutions, the US Food and Drug Administration (FDA) granted Biomedical Systems 510(k) clearance to market TruVue™, a truly wireless ambulatory ECG monitoring system. Additionally, TruVue™ has made its mark as the industry’s first cardiac Mobile Telemetry system that analyzes, records and transmits every heartbeat for up to 30 days.
