Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing magnetic retrieval devices are used, then they can retrieve metallic objects, but they are ineffective in hard-to-reach areas due to insufficient magnetic field control
Solution Approach 1:
The patent applies dynamics by making the magnetic field controllable and adjustable. The electro-magnetic field inducing circuit allows the magnetic field to be activated or deactivated as needed, enabling the device to adapt to different retrieval scenarios and reach objects in various locations effectively.
Solution Approach 2:
The patent changes the magnetic field parameters from static to dynamic by introducing an electro-magnetic field inducing circuit. This allows the magnetic field strength to be adjusted and controlled, improving the device's ability to retrieve metallic objects from hard-to-reach areas while maintaining reliability.
2Productivity
If a strong magnetic field is used for efficient retrieval, then object retrieval is improved, but energy consumption increases
Solution Approach 1:
The patent applies periodic action by using an electro-magnetic field inducing circuit that can activate and deactivate the magnetic field as needed. This allows the device to generate strong magnetic fields only when retrieval is required, improving productivity while reducing overall energy consumption compared to continuously active magnetic fields.
Solution Approach 2:
The patent optimizes energy efficiency by dynamically adjusting magnetic field parameters. The electro-magnetic field inducing circuit enables the magnetic field strength to be changed based on actual retrieval needs, achieving efficient object retrieval while minimizing unnecessary energy consumption.
3Reliability
If a magnetized retrieving member is used, then metallic objects can be retrieved, but controlled release of objects becomes difficult
Solution Approach 1:
The patent resolves the contradiction between reliable retrieval and controlled release by making the magnetic field dynamic. The electro-magnetic field inducing circuit allows the magnetic field to be activated for retrieval and deactivated for release, providing full control over both phases of operation without compromising reliability.
Solution Approach 2:
The patent applies inversion by using the absence of magnetic field (deactivation of electro-magnetic field inducing circuit) to achieve release, rather than trying to control release with a continuously active magnetic field. This approach simplifies controlled release while maintaining reliable retrieval capability.
