共同默奇在拿到东大集团项目的初期，我们收集资料，从无数繁杂的信息中提取符号，结合东大集团的理念 “合作扩充能量、共赢提升价值” ，再简化，抽象。最终，从名称的涵义突破，以东大集团的英文名作为LOGO主体，最后确定的标志是由英文、图形两部分组成，其中英文“donta”是由“don”和“tact(缩写ta)”两部分组成。

“don”原意为“阁下、先生”，在这里暗示东大具备绅士风度、高雅的气质。

“tact”原译为“晶体管和元件测试器”，符合东大的经营性质，同时传达一种严谨的、物理的、学术性的情感暗示。

根据品牌名称的读音和商品的特性，将两种语言融合贯通后转换成东大信息的英文缩写：donta。

在标志色和质地处理上，我们选择了银灰和橙黄，试图表达一种严谨精干的行业特质和充满干劲和活力的企业行动力；同时，采用具有金属光泽感的材质，传达一种简练、专业感和一种速度感，标志从另一侧面帮助企业具象化未来的发展，与东大集团本身特质完美契合。

In the early period of gaining the Dongda Group project, we Gongtong Moqi collected materials, extract signals from numerous messy information. Combined with the concept of Dongda Group of “cooperation expands energy, win-win enhances value”, we re-simplize it and make it abstract. Finally, we made a breakthrough from the connotation of the name, and with the English name of Dongda Group as the main body of the logo, and the final logo is composed of English and image two parts. The English “donta” is composed of “don” and “tact(abbreviated as ta)” two parts.

“Don” originally meant “ Your Excellency , Mr.”, here it implies that Dongda has the grace of gentleman and elegant temperament.

“Tact” originally was translated into “transistor and component tester”, which is consistent with the business feature of Dongda. At the same time, it conveys the strict, physical and intellectual feeling connotation.

According to the pronunciation of brand name and the features of products, two languages are integrated and then transferred into the English abbreviation of Dongda Information: donta.

In handling the signal coloration and texture, we choose silver gray and orange yellow , trying to express a strict and energetic industrial trait and a corporate action power full of drive and vigor. At the same time, we adopt material with metal shine in order to convey a sense of speed with simplicity and specialty. The logo helps to visualize the future development of the company, thus perfectly agreeing with the features of Dongda Group.
