LKK Design partnered with Dalian Smart Fishery Technology Co., Ltd. to develop an intelligent feeding machine that addresses critical industry challenges. Through our comprehensive product development process, we created a solution that enables precise feeding, reduces operational costs, and enhances feeding efficiency in modern aquaculture operations.

Dalian Smart Fishery sought to transform traditional feeding methods characterized by:

• Inefficient feed distribution

• Significant feed waste

• Lack of monitoring capabilities

• Poor adaptation to different farming environments

Key design objectives included:

• Adaptability: Handling pellet sizes from 1-16mm

• Precision Control: Adjustable throwing distance (0-3m) and speed (0-4r/min)

• Operational Stability: Stable current consumption (~0.6A) for continuous operation

• Smart Management: Digital monitoring and cloud connectivity

• Environmental Resistance: Long-term reliability in salt spray environments

• Easy Maintenance: Quick disassembly and cleaning capabilities

  
  

1. Design Research & User Analysis
Our team conducted extensive field research at aquaculture facilities, identifying core user needs:

• Reliability in harsh marine environments

• Simplified maintenance procedures

• Intuitive operation with minimal training

• Adaptability to various fish species and growth stages

2. Industrial Design Approach
We developed a functional aesthetic that emphasizes:

• Fully enclosed housing for maximum protection

• Streamlined forms that resist corrosion and accumulation

• Intuitive user interfaces with essential controls only

• Ergonomic handling features for daily operation

3. Mechanical Structure Engineering
The feeding mechanism incorporates several innovative features:

• Modular Throwing Disc System: Interchangeable discs with specialized patterns and angles to accommodate different feed specifications and achieve precise distribution control.

• Quick-Disconnect Mechanism: Patented coupling system enables tool-free disc removal and installation within seconds, significantly simplifying cleaning and maintenance.

• Advanced Material Selection:

• Housing: Salt spray-resistant modified ABS engineering plastic

• Feed Contact Components: Food-grade PP (polypropylene) for safety and chemical resistance

• Internal Mechanisms: 304 stainless steel bearings and POM (polyoxymethylene) moving parts for corrosion resistance and durability

4. Electronic & Electrical Systems Design
The electronic architecture ensures reliable performance:

• Power Management: DC 24V wide-voltage input (18-36V) for safety and efficiency

• Motor Control: Precision speed regulation (0-4r/min) with stable current consumption

• Connectivity: Integrated 4G/5G modules for real-time data transmission

• Cloud Integration: Seamless connectivity to smart feeding cloud platforms

• Remote Management: Web, Pad, and APP control interfaces

5. Prototyping & Validation Testing
We conducted rigorous testing through multiple prototype iterations:

• Feed distribution pattern analysis

• Motor current stability under varying loads

• Quick-disconnect mechanism durability testing

• Salt spray corrosion resistance validation

• Electronic system reliability in high-humidity conditions

6. Manufacturing & Production Implementation
Our manufacturing process ensured quality and consistency:

• DFM Optimization: Comprehensive manufacturing analysis for complex components

• Mold Engineering: Precision tooling for modified ABS and food-grade PP parts

• Quality Assurance: Established inspection protocols for mass production

• Supply Chain Coordination: Managed component sourcing and assembly processes

  
  

The smart aquatics feeding machine delivers significant benefits:
