Project Overview

iFLYTEK, a leader in China's intelligent voice and AI industry, sought to transform its advanced speech synthesis, recognition, and interpretation engines into a consumer electronics product. LKK Design was engaged as the product development partner to handle the complete hardware and software integration, from initial design to mass manufacturing.

Client Background & Challenges

iFLYTEK possessed internationally leading AI voice technologies but lacked an in-house hardware product development team. The key challenge was creating a portable simultaneous translation device that perfectly harmonized the hardware with iFLYTEK's sophisticated AI software, ensuring a seamless and intelligent user experience.

• Develop a compact, portable device with hardware fully compatible with iFLYTEK's voice AI technology

• Create an intuitive user experience for a screen-less product

• Ensure high reliability under demanding environmental conditions

• Achieve a professional aesthetic that reflects iFLYTEK's technological leadership

1. Design Research
Our team conducted extensive research into user habits and interaction patterns with translation devices. Particular attention was given to environmental adaptability, especially for regions like Xinjiang with extreme temperature variations.

2. Industrial Design

• Adopted a simple, professional design style using black as the dominant hue with anodized gold embellishment

• Created a central ring button that integrates aesthetics and function

• Implemented circular array lights for status indication, enhancing product quality perception

• Designed double camber surfaces for improved comfort and aesthetics

3. Mechanical Structure Design
Our engineering team optimized the structural design to balance aesthetic requirements with the internal component stack. Through repeated technical adjustments and process optimization, we achieved an operating temperature range of -20°C to 55°C, exceeding typical electronic product standards.

4. Electronic Design 

• Hardware Design: Developed hardware architecture specifically optimized for iFLYTEK's AI speech engines

• Firmware & Software Development: Collaborated closely with iFLYTEK's team to ensure seamless integration of voice recognition, translation, and synthesis capabilities

• Acoustic Design: Optimized sound wave transmission and user interaction patterns

5. Prototyping and Testing
We created functional prototypes for design validation and user testing. For the screen-less product, LKK Design developed specialized inspection PE to conduct comprehensive functional testing of every unit during mass production.

6. Mold Development
Our mold engineering team conducted thorough DFM analysis before mold creation, ensuring manufacturability while maintaining design integrity. We selected premium mold steels and conducted multiple T1 trial iterations to achieve perfect part quality, appearance, and precise assembly.

7. Mass Production
LKK Design established complete production lines and implemented stringent quality control measures:

• Implemented lean manufacturing processes from SMT assembly to final packaging

• Established full-process quality inspection (IQC, IPQC, OQC)

• Deployed 100% automated functional testing using our specialized inspection systems

• Managed supply chain to ensure component quality and production stability

The iFLYTEK Easy trans 600 Voice Translator developed by LKK Design achieved remarkable market success in the domestic Chinese market, generating $500 million in sales revenue through major domestic e-commerce platforms, including JD.com and Tmall, as well as through offline retail channels. This project successfully transformed iFLYTEK's advanced AI technology into a commercially successful consumer product that effectively bridges communication gaps for Chinese users.
