Background and Requirement

Customer: a smart apartment solution provider
Country/Region: Europe
Application: Smart Apartment Automation
Project Scale: 100000+ IoT gateway ODM

The customer involved in this case is headquartered in the EU and specializes in smart apartment solutions, aiming to offer users a smart, convenient, and secure living experience. Their solutions span smart apartment control, automation, energy management, and smart building automation. The company’s mission is to empower users with insights into energy consumption through sophisticated control systems, prompting them to understand energy usage and take corresponding measures to improve energy efficiency and reduce energy waste.

Challenges

In the previous generation product, the customer encountered a processor chip shortage. Besides, there were additional challenges during the development of the second-generation product.

CM3 Chip Out of Stock EVERYWHERE

The extensive unavailability of the CM3 chip, a critical component for the customer’s original gateway products, has severely impacted his supply chain and led to product disruptions. This shortage can result in delays in fulfilling customer orders, which is a matter of utmost concern. In light of these challenges, it is absolutely imperative that they take immediate and decisive action to explore alternative solutions to address the chip shortage while unwaveringly maintaining the high standards of product quality that their customers always expect.

Challenges in Lack of Expertise in Embedded System Hardware Design

Embedded System Hardware Design encompasses several critical stages: requirement analysis, schematic development, PCB design, prototyping, firmware development, and rigorous testing and validation. While the customer excels in software development and product operations, they lack dedicated in-house teams of embedded hardware and software engineers, as well as a specialized RF testing environment.

Rather than embarking on the arduous task of establishing an embedded hardware design and development team from scratch, a more efficient and cost-effective approach is to collaborate with a trusted third-party company, like Dusun IoT. This strategic partnership can expedite the entire process, ensuring that the project benefits from specialized expertise and resources, ultimately saving valuable time and resources for its customers.

Challenges in Finishing Cutting-edge Mechanical Design

The customer has unveiled a fresh ID design, necessitating the development of a novel mechanical design. This innovative concept involves unit components and an additional assembly that incorporates crucial elements like the antenna, SIM card slot, and USB interface, as well as a shielding cover that seamlessly connects these discrete components.

Here takes DSGW-210 as a reference.

The design challenge at hand is multifaceted, with a central focus on achieving not only a harmonious operational integration of these segments but also ensuring a robust and durable connection. The goal of the customer is to guarantee a product lifespan of at least five years, reflecting not only their commitment to quality and reliability but also the dynamic nature of the market they serve.

Challenges in Reliable Project Management

Successfully navigating the completion of this project presents a notable challenge. With one company based in Europe (The customer) and the other in China (Dusun IoT), each possesses specialized expertise, one in software development and the other in embedded system hardware. The key to overcoming this geographical and expertise divide lies in closely coordinated efforts and seamless communication.

To ensure project success, it is significant to establish clear and well-defined milestones that serve as guiding markers throughout the project’s lifecycle. Equally crucial is maintaining open lines of communication between teams on both sides of the globe. This ongoing dialogue facilitates the exchange of insights, progress updates, and immediate issue resolution, fostering a collaborative environment that transcends geographical boundaries.

Furthermore, a proactive approach to identifying and addressing potential challenges is pivotal. Anticipating issues before they become roadblocks allows for timely mitigation and ensures that the project stays on schedule. The complexities of this international collaboration and a successful project outcome delivery need to establish clear milestones, maintain open lines of communication, and proactively addressing potential challenges.

Challenges in Stable Supply Chain Management

In pursuit of cost efficiency, on-time delivery, and top-tier product quality, the search for a dependable third-party partner with exceptional supply chain management becomes paramount. Swift and reliable delivery of key components stands as a linchpin in averting any production setbacks.

Given the pivotal role of these components, the selected partner must exhibit robust supply chain management capabilities. This encompasses not only the ability to guarantee on-time delivery but also to uphold a steadfast commitment to unwavering product quality standards. The successful execution of these critical factors hinges on the meticulous management of the supply chain, underscoring the importance of selecting a partner with a proven track record in this domain.

Challenges in Regulatory Compliance

Compliance with a myriad of local and international standards, including FCC, CE, CSA, and Z-Wave, is an indispensable requirement for the customer’s products. However, obtaining these certifications can be a complex and time-consuming endeavor, often necessitating additional testing and comprehensive documentation. Nonetheless, securing these certifications is paramount for the successful marketing of products.

In light of this, it is imperative that the chosen third-party partner possesses not only a deep understanding of these certification requirements but also a wealth of experience in successfully obtaining them. Their expertise in navigating the intricacies of compliance procedures and their ability to efficiently manage the certification process can significantly expedite the time-to-market while ensuring that the finished product complies with all relevant regulations.

Post-Production Support

Given the potential for adjustments in hardware or software over time, it is important to acknowledge that earlier product batches may require updates to ensure they maintain optimal performance and functionality. Therefore, it is imperative that the chosen third-party partner offers comprehensive device upgrade solutions.

The ability to provide efficient and effective upgrades is essential to ensuring customer satisfaction and maintaining the competitiveness of the customer’s products in the market. This includes not only the technical capability to implement updates but also the provision of clear documentation and support to guide end users through the upgrade process seamlessly.
