Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If induction coils are arranged directly on the axial connecting areas of rod elements, then energy and data transmission can be achieved, but the mechanical connection areas are interfered with and retrofitting becomes difficult
Solution Approach 1:
The induction coils are moved from the axial connecting area to the radial space between inner and outer pipes, utilizing the radial dimension instead of axial space. This allows energy and data transmission without interfering with mechanical connections at the axial ends of rod elements, enabling easy retrofitting while maintaining transmission reliability
Solution Approach 2:
The induction coils are nested within the receiving space formed between the inner pipe and outer pipe. The first induction coil is located at the outer circumference of the inner pipe, and the second induction coil is located at the inner circumference of the outer pipe, allowing both to coexist in the radial space without interfering with each other or the mechanical connections
2Reliability
If induction coils are arranged on the inner or outer pipe, then energy and data transmission is enabled, but the connector systems at the front faces are interfered with
Solution Approach 1:
Instead of placing induction coils on the axial faces where connectors are located, the solution utilizes the radial dimension by positioning coils between the inner and outer pipes. This dimensional separation allows connector systems to remain simple and unchanged while enabling energy and data transmission functionality
3Ease of operation
If segmental ring segment parts are used for induction coils, then retrofitting becomes easier and mechanical connections are preserved, but the device complexity increases
Solution Approach 1:
The induction coils are constructed from several ring segment parts that can be assembled together. This segmentation allows the coils to be easily installed in the radial space between pipes without requiring complex modifications to existing rod elements, facilitating retrofitting while maintaining functional reliability
