“I swear: I volunteered to join the constant source product design team and follow the constant source design specification. Whenever and wherever the first principle of design safety was always followed, I was responsible for the product I designed. The oath: Chen Wentao, Huang Zupeng, Jia Xiaojun... "The 13 product manager with the" engineering ring " solemn sworn sound echoed at Heng Yuan, highlighted the determination and commitment of each team member" to be secure for its own ", which opened the first propaganda prelude to his establishment for 15 years.。

    The source of Shenzhen Heng is to focus on the solution of LED lighting and display control system in the field of traffic. The company advocates the idea of home, enterprise and co development. It takes customers as the center, the diligent person as the base, the internationalization as the goal, the perseverance and honesty, at the same time, striving for a hundred year old store for the customers.

    The field of transportation, especially rail transit, is a public social field, and product safety is particularly important. In October 28, 2010, Mr. Li Mingkui, the chairman of the company, went to the headquarters of the bombardier company in North America for a visit, and found that all of the bombardiers who had been engaged in engineering technology were wearing a "tail ring" on the fingers of the high officials or professional technicians. ...                                            

    The ring, originated from the design tragedy of the Quebec bridge in Canada, was made of a twisted steel bar, its name, the Canadian engineer's ring. In 1900, in order to build the longest bridge in the world, the bridge that might have been an immortal masterpiece was written by an engineer at 600 metres in error from 500 meters. When the bridge was about to be completed, there was a collapse, killing at least 75 people and injuring many people. Later, the design and construction of the bridge began again, but history did not give blood lessons. In September 1916, the tragedy was repeated once the material index of a certain supporting point was not in place. This time, the longest bridge in the middle suddenly collapsed, killing 10 workers. After many years, the bridge was finally opened to traffic in 1917, and has become the longest cantilever span bridge up to now. In 1922, the seven major engineering colleges in Canada paid for all the debris in the process of collapse, and decided to make these steel bars into a ring and send them to a graduate of the engineering college.

    Later, such a tradition continued, and the medal of the engineer became the most expensive ring in the world. They are used as a warning and an admonition on the little finger of the commonly used signatures of engineers. They are the flesh and blood of the dead, and the alarm bell for engineers. They are not as valuable and eternal as diamonds, but they remind the engineers of their responsibilities and commitments at any time. Engineers are responsible for the fragile life of others. 

    This story deeply touched the chairman of the company, Mr. Li Mingkui, and both enterprises and individuals should bear their social responsibilities for the products they produce or design. In the past few years, the company's products have been widely used in China's high-speed train, intercity train, and metro vehicle. The lamps and lanterns have been sold to Europe and America, especially in the joint design and development of the North American Bombardier, from standardized products to BART projects, making the enterprise management a new step. But enterprise safety and product design safety have always been the focus of his attention. This year coincides with the establishment of 15th anniversary of the permanent source, the company held the signing ceremony of "product design safety", and sincerely invited the representative of the bombardier product design and the project team representative from North America. Carl and structural engineer Even, the guest electrical engineer, issued the " excellent designer" award and the " engineering ring" responsibility for the constant source design team. With the ring, the design safety and responsibility will be deeply embedded in the hearts of the members of each team. At the same time, the company has witnessed the sanctity. And the solemn moment.

    This ring is not precious, nor silver, but precious. It represents an honor and a responsibility. It embodies the confidence and determination of our design team to regard product design security as its own responsibility. It is also the quality policy of "quality first, continuous innovation, market oriented, customer first" and "perseverance, innovation, honesty, service, people-oriented, and reasonable pursuit."
