Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automated systems for processing fruit and vegetable products, especially blueberries, face challenges due to their complexity, size, and delicacy, making transportation and installation costly and difficult, and require sophisticated and bulky structures that are impractical for global distribution and high productivity demands.
Innovation Solution
A modular system comprising a first unit with a loading station, pre-sizing station, pre-selection station, and first alignment station, and a second unit with a second alignment station, optical sizing station, and distribution station, designed to be compact and transportable in a single container, with quick coupling mechanisms and conveyor belts for efficient alignment and processing, ensuring high productivity and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional automated systems are designed to process blueberries with high productivity, then processing capacity increases, but system complexity and structural bulk increase making transportation and installation difficult
Solution Approach 1:
The system is divided into multiple independent processing modules (receiving module, washing module, sorting module, packaging module) that can function separately but are integrated through a centralized control unit. This segmentation allows each module to be optimized for specific tasks while maintaining overall high productivity, and the modular structure facilitates easier transportation and installation compared to a monolithic system.
Solution Approach 2:
The control unit serves multiple functions simultaneously: it coordinates all modules, monitors product quality through vision systems, controls sorting mechanisms, and manages packaging operations. This multi-functionality reduces the need for separate dedicated control systems for each function, thereby reducing overall system complexity while maintaining high processing capacity.
2Measurement precision
If sophisticated vision and control stations are added to classify products by multiple parameters, then classification accuracy improves, but system dimensions and installation requirements increase
Solution Approach 1:
Multiple sensing functions (vision inspection, size measurement, quality assessment) are merged into integrated sensing stations that perform multiple measurements simultaneously. The control unit consolidates data from various sensors to make classification decisions, eliminating the need for separate dedicated stations for each measurement parameter and reducing overall system footprint.
Solution Approach 2:
The system uses optical vision technology to perform three-dimensional assessment of fruit characteristics (size, shape, color, surface defects) from two-dimensional imaging. This dimensional transformation allows comprehensive classification accuracy without proportionally increasing physical system dimensions, as computational analysis extracts multiple parameters from planar images.
3Adaptability or versatility
If the system is designed as a complete integrated unit, then functionality is complete, but transportation to remote locations becomes prohibitively expensive and complex
Solution Approach 1:
The complete processing system is segmented into modular units (receiving module, washing module, sorting module, packaging module) that can be manufactured separately, transported independently to remote locations using standard logistics, and then assembled on-site. Each module maintains its functional integrity during transport and can be tested independently before final integration.
Solution Approach 2:
The system employs quick-connect interfaces and adjustable components that allow for dynamic assembly and disassembly. Modules can be configured in different arrangements based on available space at the installation location, and the system can be expanded or contracted by adding or removing modules as needed, providing flexibility for both transportation and deployment.
