Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If electronic and electrical device component scrap is processed in larger amounts in copper smelting flash furnaces, then the efficiency of valuable metal recovery improves, but the amount of carbon component from organic substances increases causing over-reduction troubles
Solution Approach 1:
The patent applies preliminary action by crushing the electronic and electrical device component scrap before processing in the copper smelting flash furnace. This pre-crushing step reduces the volume and surface area of the scrap, thereby controlling the amount of carbon component released during smelting and preventing over-reduction troubles while maintaining processing efficiency
2Reliability
If electronic and electrical device component scrap is crushed to reduce volume before processing, then over-reduction troubles are prevented, but unwanted substances (smelting inhibitors) are introduced in larger amounts
Solution Approach 1:
The patent applies the taking out principle by using a sorting machine to separate and remove unwanted substances including smelting inhibitors from the crushed scrap before processing. This extraction step eliminates the harmful factors introduced by crushing while preserving the volume reduction benefits, ensuring smelting process stability
3Object-generated harmful factors
If manual sorting is used to remove substances that inhibit smelting, then smelting inhibitors are reduced, but the process becomes time-consuming and labor-intensive
Solution Approach 1:
The patent applies mechanics substitution by replacing manual sorting with an automated sorting machine that uses sensors and mechanical mechanisms to identify and separate smelting inhibitors from the scrap. This automation dramatically reduces sorting time and labor requirements while effectively removing harmful substances
