Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a metal hollow tube is used as an electromagnetic barrier in a measuring vessel, then electromagnetic shielding effectiveness is improved, but the weight and manufacturing complexity increase
Solution Approach 1:
The electromagnetic shielding function is segmented from the structural function. The hollow tube provides structural support while a separate removable optical article provides electromagnetic shielding. This segmentation allows each component to be optimized independently - the tube can be lightweight non-metallic while the shielding layer provides the required electromagnetic protection.
Solution Approach 2:
The invention uses a composite structure combining a non-metallic hollow tube with a removable optical article that has a reflective metal material layer. This composite approach allows the vessel to achieve electromagnetic shielding effectiveness without the entire structure being made of heavy metal, thus reducing overall weight while maintaining shielding performance.
2Object-affected harmful factors
If a metal hollow tube is used as an electromagnetic barrier, then electromagnetic shielding is improved, but manufacturing cost and complexity increase due to required surface treatments
Solution Approach 1:
The shielding function is separated into a distinct removable optical article that can be manufactured independently and then assembled into the vessel. This eliminates the need for complex surface treatments on the hollow tube itself, as the tube can be made from simple non-metallic material through standard manufacturing processes.
Solution Approach 2:
The removable optical article with its reflective metal material layer can be manufactured more economically than permanently bonding such layers to metal tubes. The article can be produced using cost-effective techniques and replaced if needed, reducing overall manufacturing cost and complexity.
3Weight of moving object
If a non-metallic hollow tube is used, then weight and manufacturing ease are improved, but electromagnetic shielding effectiveness deteriorates
Solution Approach 1:
The removable optical article acts as an intermediary between the non-metallic hollow tube and the electromagnetic fields. This intermediate layer provides the electromagnetic shielding function that the non-metallic tube cannot provide on its own, while allowing the tube to remain lightweight and easy to manufacture.
Solution Approach 2:
The vessel becomes a composite structure where the non-metallic tube provides structural support and the removable optical article with reflective metal material provides electromagnetic shielding. This composite approach allows the system to achieve both lightweight construction and effective electromagnetic protection.
4Manufacturing precision
If complex surface treatments are applied to the internal surface of the tube, then optical reflection quality is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The optical reflection function is segmented into a separate removable optical article rather than being integrated into the tube structure. This allows the reflective surface to be optimized for optical performance while the tube can be manufactured using simple processes without complex surface treatments.
Solution Approach 2:
Instead of creating a complex reflective surface on the tube itself, the invention uses a separate optical article that copies or replicates the required optical reflection properties. This article can be manufactured with precise optical surfaces while the tube remains simple to produce.
