Solution Overview
Problem
Existing transport systems face challenges in achieving simple and rapid production while ensuring precise alignment and minimal energy loss of electromagnetic waves, as well as accommodating thermal expansion, in rail vehicle systems.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If profile parts are rigidly connected to ensure precise alignment and minimal energy loss, then electromagnetic wave transmission is improved, but thermal expansion compensation is hindered
Solution Approach 1:
The connecting part is designed with thin walls (less than 5% reduction in waveguide cross-sectional area) to provide flexibility for thermal expansion while maintaining electromagnetic wave transmission. The thin-walled structure allows elastic deflection to accommodate thermal length changes of profile parts while still forming an effective electrical connection for the cavity surface.
Solution Approach 2:
The connecting part is designed to be elastically deflectable, allowing it to dynamically adapt to thermal expansion and contraction of the profile parts. This dynamic capability enables the system to maintain both precise alignment for electromagnetic wave transmission and accommodation of thermal dimensional changes.
2Loss of energy
If profile parts are closely connected to minimize air gaps and reduce electromagnetic wave damping, then energy transmission is improved, but thermal expansion accommodation is reduced
Solution Approach 1:
The thin-walled connecting part creates a minimal air gap (less than 5% cross-sectional area reduction) that sufficiently reduces electromagnetic wave damping while providing enough space for thermal expansion accommodation. The thin wall structure allows the connection to remain electrically effective for the cavity surface while physically accommodating dimensional changes.
3Manufacturing precision
If complex connection mechanisms are used to achieve precise alignment and thermal compensation, then system performance is improved, but production complexity increases
Solution Approach 1:
The connecting part automatically performs alignment and thermal compensation functions through its inherent elastic properties and geometric design, without requiring external control systems or complex adjustment mechanisms. The elastic deflection and thin-walled structure self-adjust to maintain precise alignment while accommodating thermal changes.
Solution Approach 2:
The connecting part achieves precise alignment and thermal compensation through carefully selected material and geometric parameters (thin wall thickness, elastic modulus, cross-sectional area ratio less than 5%), rather than through complex mechanical mechanisms. This parameter-based approach simplifies the overall device complexity.
4Strength
If thick-walled connecting parts are used to provide sufficient structural strength and electrical connection, then mechanical stability is improved, but electromagnetic wave attenuation increases
Solution Approach 1:
The connecting part uses thin walls to minimize electromagnetic wave attenuation (keeping cross-sectional area reduction below 5%) while maintaining sufficient structural strength through optimized material selection and geometric design. The thin-walled structure reduces the electrical path length that waves must traverse, minimizing attenuation.
Solution Approach 2:
The connecting part may utilize composite material structures or optimized material properties to achieve the required structural strength with reduced wall thickness, thereby maintaining both mechanical stability and low electromagnetic wave attenuation.
