Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional measurement tools (tape, caliper, meter ruler, cotton thread, chest angler, electronic scale) are used to measure poultry body size, then comprehensive measurement indicators can be obtained, but the measurement process becomes labor-intensive and the data accuracy deteriorates
Solution Approach 1:
The patent replaces traditional mechanical measurement tools (tape, caliper, meter ruler) with a 3D laser scanning system that uses optical fields to capture poultry body dimensions. The laser scanner projects laser lines onto the poultry body and captures the reflected light patterns to automatically generate 3D models, eliminating manual mechanical measurement operations while significantly improving measurement accuracy and comprehensiveness
Solution Approach 2:
The patent creates a digital 3D copy of the poultry body through laser scanning. Instead of physically measuring the actual poultry with multiple tools, the system generates an accurate digital replica that can be measured and analyzed computationally, reducing operational complexity while maintaining comprehensive measurement capabilities
2Loss of information
If multiple measurement tools are used to obtain comprehensive body size indicators, then measurement coverage is improved, but the measurement process time increases and productivity decreases
Solution Approach 1:
The patent merges multiple measurement functions into a single integrated 3D laser scanning system. Instead of using separate tools for different body dimensions (wing span, body length, girth, etc.), the laser scanner simultaneously captures all these measurements in one scanning operation, achieving comprehensive data collection while dramatically improving productivity
Solution Approach 2:
The patent implements continuous laser scanning across the entire poultry body in a single uninterrupted operation. The laser scanner continuously projects laser lines and captures reflected patterns along the body contour, ensuring complete measurement coverage without stopping or repositioning multiple tools, thereby maintaining both data completeness and high efficiency
3Reliability
If manual measurement operations are performed with traditional tools, then device complexity is reduced, but measurement reliability and data consistency deteriorate
Solution Approach 1:
The patent replaces manual mechanical measurement operations with an automated optical measurement system. The 3D laser scanner automatically projects laser lines, captures reflected patterns, processes images, and generates measurement data without human intervention, ensuring consistent and reliable results while the complexity is managed through integrated automation
Solution Approach 2:
The patent implements self-service measurement where the laser scanning system automatically performs all measurement tasks without requiring operator skill or judgment. The system autonomously captures data, processes images, generates 3D models, and extracts body size parameters, ensuring reliable and consistent measurements while the complexity is encapsulated within the automated system

Data Source
AI summary
The invention introduces a system for acquiring data on poultry body size, utilizing a baseplate for immobilization. After positioning the poultry, the system adjusts a fixing device on a rod to secure the poultry's knee joints using a fixing clip, thereby stabilizing the poultry's body. A 3D laser scanning lens then conducts comprehensive 3D scanning of the poultry's entire body, transmitting the data to a 3D microcomputer which generates an optimal dynamic model image. This microcomputer organizes and analyzes data from the model using a computer algorithm, ultimately displaying the poultry's body size indices on the 3D microcomputer's display. This method circumvents inaccuracies common with traditional tools like electronic scales, enhancing the speed and precision of poultry body composition data collection.
