Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a gear-driven scanning mechanism is used, then the scanning operation can be achieved, but the structure becomes complicated with many assembly parts
Solution Approach 1:
The patent replaces the traditional gear-driven mechanical scanning mechanism with a magnetic field-based scanning mechanism. The magnetic probe rotates under the influence of magnetic forces without requiring complex gear assemblies, linkages, or multiple mechanical components. This substitution eliminates the need for gears, shafts, and linkages while achieving the same scanning function, thereby significantly reducing structural complexity.
2Ease of operation
If a gear-driven scanning mechanism is used, then the scanning operation can be achieved, but the system becomes vulnerable to wear and tear
Solution Approach 1:
The patent eliminates mechanical contact components like gears and linkages that are susceptible to wear and tear by using a magnetic field-based actuation system. The magnetic probe is driven by magnetic forces without mechanical contact, which eliminates friction, wear, and the need for lubrication, thereby significantly improving system reliability and robustness.
3Ease of operation
If a gear-driven scanning mechanism is used, then the scanning operation can be achieved, but the production cost increases
Solution Approach 1:
The patent replaces expensive mechanical components (gears, linkages, precision shafts) with simpler magnetic field-based components. The magnetic actuation system requires fewer precision-machined parts and eliminates the need for complex assembly procedures, thereby reducing manufacturing costs and making the device more economically viable.
4Ease of operation
If a gear-driven scanning mechanism is used, then the scanning operation can be achieved, but the assembly takes much time
Solution Approach 1:
The patent replaces the complex gear-driven mechanism with a simplified magnetic actuation system that has fewer components and simpler assembly requirements. The magnetic probe and housing can be assembled with minimal fastening and alignment steps, eliminating the time-consuming assembly of multiple mechanical components, thereby significantly reducing assembly time.
5Ease of operation
If a gear-driven scanning mechanism is used, then the scanning operation can be achieved, but the components are difficult to pack and there is a risk of losing components during transportation
Solution Approach 1:
The patent integrates the magnetic scanning components into a compact, self-contained housing that minimizes the number of separate parts. The magnetic probe, actuation mechanism, and support structures are combined into a unified assembly that can be easily packaged as a single unit, eliminating the risk of losing small components during transportation and simplifying logistics.
