Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual separation and screening is used to separate non-metal scrap and metal scrap after pyrolysis, then the separation can be performed, but the process is time-consuming and labor-intensive, resulting in low efficiency and increased production costs
Solution Approach 1:
The patent replaces the manual mechanical separation system with an automated magnetic separation system. The magnetic separator uses magnetic fields to automatically separate metal scraps from non-metal scraps, eliminating the need for manual labor and significantly improving separation efficiency while reducing time consumption.
Solution Approach 2:
The magnetic separation system enables the mixture to separate itself based on magnetic properties. Metal scraps are automatically attracted to the magnetic separator while non-metal scraps pass through, achieving self-service separation without human intervention and dramatically reducing both time and labor costs.
2Ease of manufacture
If manual stripping and screening is performed to separate mixed scraps, then the scraps can be separated, but the process requires significant labor effort, increasing production costs
Solution Approach 1:
The patent substitutes manual stripping and screening operations with an automated magnetic separation system. This mechanical substitution eliminates the need for labor-intensive manual operations, reducing both production costs and operational difficulty while maintaining effective separation of metal and non-metal scraps.
Solution Approach 2:
The magnetic separation system allows the mixture to self-separate based on inherent magnetic properties of metal scraps. This self-service mechanism eliminates the need for human labor in the separation process, making the operation extremely easy while significantly reducing production costs associated with manual labor.
3Productivity
If the non-metal scrap is covered on the surface of metal scrap after pyrolysis, then the mixture is formed, but the tight adhesion makes manual stripping difficult and time-consuming
Solution Approach 1:
The patent replaces difficult manual stripping operations with magnetic separation. The magnetic field acts directly on the metal scraps regardless of the non-metal scrap covering, enabling rapid separation without the need to physically strip or break the covering material, thus dramatically improving separation speed while reducing operational complexity.
Solution Approach 2:
The magnetic separation system exploits the inherent magnetic properties of metal scraps to achieve self-service separation. Even when non-metal scrap is adhered to the surface, the magnetic field penetrates and attracts the metal scraps, enabling them to self-separate automatically without manual intervention and overcoming the adhesion problem efficiently.

AI summary
A waste tire separation recycling treatment device includes a machine rack, a pair of crushing rollers, a pair of stripping wheels and a guiding portion. After a waste tire, which is performed with pyrolysis, is placed in the device to obtain a non-metal scrap, a metal scrap and a mixture, and above 98% of the non-metal scrap, the metal scrap and the mixture are sequentially rolled and striped off to transform them into the non-metal scrap and the metal scrap. Afterward, several separation processes are performed to separate the non-metal scrap and the metal scrap, thereby greatly increasing the efficiency of separation recycling treatment.
