In the rapidly growing electric vehicle market, HANSU identified critical gaps in available charging solutions. While demand for EV chargers was increasing, most products on the market suffered from similar shortcomings: uncomfortable grip designs, easily lost protective caps, and lack of distinctive brand identity. HANSU approached LKK Design with a clear vision - to develop a charging solution that would not only address these practical issues but also establish a strong brand presence in the competitive new energy sector.

LKK Design's team conducted thorough analysis to define key project goals:

• Solve fundamental ergonomic issues for improved user comfort

• Develop innovative solution for protective cap retention

• Create distinctive product identity reflecting HANSU's brand values

• Ensure product durability and safety compliance

• Achieve market differentiation through design excellence

Design Research

Our team initiated an extensive research phase, analyzing user behavior across multiple charging scenarios. Through observational studies and competitive product analysis, we identified that majority of users experienced hand discomfort during extended use, while protective cap loss was a frequent complaint. These insights directly informed our design strategy, prioritizing ergonomic excellence and practical reliability.

Industrial Design

Drawing inspiration from natural forms, we developed an innovative approach:

• Biomimetic Design: The elegant curvature of an elephant's trunk inspired our form language, creating a natural, intuitive grip

• Ergonomic Optimization: Contoured surfaces distributed pressure evenly across the palm, significantly reducing fatigue

• Material Selection: Strategic implementation of rubberized polymers enhanced grip security while providing tactile differentiation

• Visual Identity: Custom colorways and finishes established strong brand recognition

Mechanical Structure Design

Our engineering team focused on robust construction:

• Unified housing design eliminated traditional parting lines

• Custom polymer blends ensured optimal impact resistance

• Advanced thermal management maintained safe operating temperatures

• Reinforced cable interface withstands repeated bending stress

• Innovative cap retention system using material elasticity

Prototyping and Testing

We employed rapid prototyping to validate our design:

• Multiple iterations for ergonomic refinement

• Durability testing exceeding industry standards

• User testing for intuitive operation validation

• Environmental testing for various usage conditions

• Final prototype approval after three refinement cycles

The collaboration between HANSU and LKK Design resulted in significant achievements:
