Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If calcium oxide is produced by directly calcining egg shells, seaweed sediment egg masses, or coral sediments, then the production process is simple, but the calcium oxide contains impurities mixed due to dust and soot resulting in low purity
Solution Approach 1:
The production process is divided into multiple distinct stages: washing and drying shellfish, pulverizing into powder, heat treatment, electrolysis treatment, and ultrasonic treatment. Each stage addresses specific impurities and transforms the material progressively, separating the calcium oxide production from direct calcination of raw materials.
Solution Approach 2:
The shellfish are washed and dried before pulverizing, and the powder undergoes heat treatment before electrolysis. These preliminary actions remove surface impurities and prepare the material for subsequent treatments, preventing contamination in later stages and ensuring high purity throughout the process.
2Manufacturing precision
If high-purity calcium oxide is produced through multiple treatment steps, then the calcium ion availability increases, but the process complexity and treatment steps increase
Solution Approach 1:
The process uses continuous treatment steps where each stage builds upon the previous one: washing removes external contaminants, pulverizing creates fine particles for uniform treatment, heat treatment removes organic matter, electrolysis ionizes calcium, and ultrasonic treatment eliminates remaining impurities. This continuous progression ensures high purity without requiring separate discrete operations.
Solution Approach 2:
The process utilizes changes in physical and chemical parameters at each stage: temperature changes during heat treatment (raising temperature to decompose carbonates), voltage application during electrolysis (applying electric field to ionize calcium), and ultrasonic frequency vibrations (applying mechanical oscillations to remove impurities). These parameter changes enable each treatment step to target specific impurities efficiently.
