Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple independent detection apparatuses are used for simultaneous comparison experiments, then measurement comprehensiveness is improved, but device complexity and space occupation increase
Solution Approach 1:
The patent combines multiple detection functions into a single integrated apparatus. Multiple reaction chambers are arranged within one device, allowing simultaneous conduct of test material and standard material experiments. The control system integrates temperature control, air supply, and stirring functions for all chambers through a unified platform, eliminating the need for multiple separate apparatuses while maintaining comprehensive measurement capabilities.
Solution Approach 2:
The detection apparatus is designed with multi-functionality to perform various biodegradability measurements (disintegration degree, biodegradation rate, ecological toxicity) within a single device. The reaction chambers can accommodate different test configurations, and the integrated control system manages multiple experimental conditions simultaneously, making the apparatus universal for comprehensive biodegradability assessment.
2Stability of the object's composition
If manual stirring is performed during high-temperature fermentation, then material mixing is achieved, but laboratory environment is polluted by generated odor
Solution Approach 1:
The patent replaces manual mechanical stirring with an automated stirring mechanism. A stirring blade connected to a drive system automatically mixes the materials in the reaction chambers during high-temperature fermentation. This eliminates the need for operators to manually open and stir the chambers, thereby preventing odor release into the laboratory environment while maintaining effective material mixing.
Solution Approach 2:
The patent introduces an air-tight sealing system as an intermediary between the reaction chamber and the external environment. The sealing structure prevents odor generated during high-temperature fermentation from escaping into the laboratory, while the automated stirring mechanism operates within the sealed chamber to maintain material mixing without direct human contact.
3Volume of moving object
If reaction chamber volume is compressed to reduce space occupation, then space efficiency is improved, but high-temperature fermentation cannot be achieved due to volume limitation
Solution Approach 1:
The patent employs a nested arrangement where multiple reaction chambers are vertically stacked within the device housing. This space-efficient configuration allows multiple experimental units to occupy minimal footprint space while each chamber maintains sufficient internal volume for effective high-temperature fermentation. The nested structure optimizes space utilization without compromising the thermal processing capabilities of individual chambers.
4Ease of operation
If manual loading and unloading of materials is performed, then operation flexibility is maintained, but operational convenience is reduced
Solution Approach 1:
The patent incorporates an automated material discharge system that enables self-service operation. The reaction chambers are equipped with discharge mechanisms that automatically eject processed materials without requiring manual intervention. The apparatus performs feeding, temperature control, stirring, and discharging operations autonomously, significantly improving operational convenience and reducing the time loss associated with manual material handling.
