Research and Development Philosophy
Adhering to the Environmentally Caring green R&D concept, Sunon relies on its excellent R&D capabilities to invest in low energy consumption, long life, low noise, reduced parts and simplified manufacturing environmental design, and continues to launch high-performance and environmentally friendly green products.
R&D Concept and Strategy
R&D innovation is a strong driving force that stimulates the sustainable development of enterprises. Sunon has always adhered to the business philosophy of brand, innovation, and value, becoming a leading manufacturer of precision motors, micro fans and cooling modules globally step by step.
From 2018 to 2024, Sunon allocated at least 6% of its annual revenue to R&D expenses every year, actively investing a large amount of manpower, financial resources and time in innovation and invention, insisting on the invention of intelligent micro motors, and continuing to cultivate high-tech talents. It is believed that this will not only enable the sustainable development of the enterprise, but also strengthen Sunon's competitive advantage in R&D and innovation.
Thanks to the continuous R&D and innovation efforts of Sunon's R&D team, new products are launched every year. So far, it has won the Taiwan Excellence Award for 24 consecutive years, and has also won many international awards such as the Golden Pin Design Award and the German iF Product Design Award.
Product Energy-saving and Environmental Performance
Sunon has always been committed to product R&D, believing that improving R&D technology can bring more convenience to humans and reduce the burden on the environment. As a member who cares about the earth, in addition to implementing environmental awareness of energy saving and carbon reduction within the Company, promoting various carbon reduction measures, protecting the earth's resources, and reducing harm to the earth, Sunon also continues to invest in product efficiency improvement R&D to achieve energy saving and electricity saving effects, hoping that the general public and consumers can feel Sunon's actual actions and contributions to being environmentally friendly and loving the earth.
Many of Sunon's products have undergone efficiency improvements and have been widely used in industries such as LED, industrial/medical, mobile devices, automotive, home appliances, channel customers, cloud networking, computers, office equipment, and head-mounted devices. In 2024, the revenue from the Company's energy efficiency related products was NT$12.452 billion, saving 762.46 million kWh of electricity for global customers. The environmental performance of product energy saving and carbon reduction is as follows:
| Energy Saving | Carbon Emission Reduction |
|---|---|
| 7762.46 million kWh = 2,744.9 million MJ (megajoules) | 376,700 metric tons |
Note 1: Calculated using the electricity emission factor of 0.494 announced by the Bureau of Energy, Ministry of Economic Affairs (2023).
Note 2: Sunon's new generation models all adopt new motor technology and circuit design. According to actual tests, compared with the old motor and circuit design of the previous models, the new models can reduce power consumption by more than 10% on average. Therefore, we calculate the "annual shipment of energy-saving products x 10% of power consumption x actual operating time" based on the actual operating time determined by the product application to obtain the result.
Product Safety Certification and Energy-saving Label Declaration
Sunon conducts product electrical characteristics, safety and other tests through international standard certification bodies (such as UL, TUV Rheinland, etc.) according to customers' requirements for various product safety regulations. After meeting the safety standards preset by international standard certification bodies or the government, it successfully obtains safety compliance certificates.
To meet the specific product safety requirements of the Bureau of Standards, Metrology and Inspection (BSMI) of the Ministry of Economic Affairs, so far, in addition to meeting the safety requirements approved by BSMI and obtaining safety compliance certificates to ensure product safety, Sunon's products also comply with Taiwan's energy-saving label regulations and have successfully obtained energy-saving labels. In 2024, there were no incidents of violations related to products, services and marketing promotion.
The company's products are mainly B2B, and B2C products account for 0.65% of total revenue, of which ventilation fan products have successfully obtained energy-saving labels, accounting for 0.13% of total revenue.
Patent Management
To enhance Sunon's R&D and innovation capabilities in products, technologies, processes or equipment, and to encourage employees to engage in more R&D and innovation, thereby accumulating abundant intellectual assets and extending continuous R&D and creative capabilities. Employees can submit patent applications through the internally established "Patent Proposal Application System". Moreover, receiving bonuses and rewards in accordance with the "Measures for Encouraging Employee Invention and Creation" after the proposal is approved, the top three outstanding employees in annual innovation R&D patent applications are also publicly commended in the year-end interview before the Lunar New Year, actively encouraging employees to create valuable assets with their professional R&D and innovation capabilities.
Besides, the "Intellectual Property Area" is set up on the Company's intranet, and the Company's patent technology is built into the "Intellectual Property Area" for relevant internal colleagues to understand the scope and application of the Company's patent technology. Competitors' patent technology information is also built into the Company's intranet "Intelligent Collaborative Patent Value-added System" for employees to understand the current technology trends and direction of peers from competitors' technology distribution, thereby stimulating employees' R&D and innovation ideas.
As of 2024, Sunon's patents have accumulated 3,429 granted patents, showing Sunon's emphasis on patent rights and high expectations for self-R&D and innovation.
