Innovation Solution
A device and method utilizing machine vision with a supporting mechanical arm, working mechanical arms, a picking manipulator, a grasping manipulator, a collection device, and a visual system to automate the picking and collection of Brasenia schreberi, including stepper motors, conveyor belts, and manipulators designed to grip and transport the plant.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional hand-picking method is used, then picking can be performed with simple equipment, but labor intensity is high and efficiency is low
Solution Approach 1:
The system uses machine vision to automatically detect and locate Brasenia schreberi plants, and the mechanical arms autonomously perform picking operations without continuous human intervention. The control system coordinates multiple components to complete the picking task independently, reducing manual labor while maintaining operational autonomy.
Solution Approach 2:
The patent replaces the manual mechanical picking system with an automated system comprising mechanical arms, vision sensors, and control units. The mechanical arms substitute human hands for picking, while the vision system replaces human visual detection, achieving mechanization and automation of the previously manual process.
2Productivity
If hand-picking is used, then equipment cost is low, but economic yield per unit area declines due to inefficiency
Solution Approach 1:
The mechanical arm system is designed to perform multiple functions including plant detection, grasping, picking, and transport within a single integrated platform. The vision system and mechanical components work together to achieve both location and collection functions, reducing the need for separate equipment while improving overall productivity.
Solution Approach 2:
The control system acts as an intermediary that coordinates between the vision system, mechanical arms, and collection container. It processes visual data to determine plant locations and directs the mechanical arms to execute picking actions, enabling efficient coordination without requiring complex direct mechanical linkages between all components.
3Ease of operation
If manual picking is used, then equipment is simple, but pickers face harsh working conditions in summer and early autumn
Solution Approach 1:
The automated system performs the picking operations independently without requiring human pickers to physically work in harsh environmental conditions. The mechanical arms and vision system handle the demanding tasks of locating and harvesting plants during hot summer and early autumn periods, eliminating human exposure to adverse weather.
Solution Approach 2:
The patent replaces the human operator's physical interaction with the plant with an automated mechanical system. The mechanical arms perform grasping and picking actions that would otherwise require human hands, while the vision system detects plants that would otherwise require human visual search, completely substituting human labor in the harsh working environment.
