Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the phase conductor is divided into several parallel conductor tracks with helical winding to achieve flexibility, then the flexibility and current distribution are improved, but the mechanical complexity increases due to the need for central guide rods and caps to stabilize the conductor
Solution Approach 1:
The phase conductor is divided into multiple parallel conductor tracks that can move independently relative to each other. This segmentation allows each track to flex independently while maintaining electrical continuity, achieving flexibility without requiring complex stabilization mechanisms like central guide rods or caps.
Solution Approach 2:
Electrically insulating means are introduced as intermediaries between adjacent conductor tracks to prevent electrical contact while allowing mechanical movement. This intermediary solution enables the conductor tracks to support each other mechanically while maintaining electrical insulation, replacing the need for complex stabilization structures.
2Device complexity
If conductor tracks are supported directly on each other to simplify the structure, then mechanical complexity is reduced, but electrical insulation between tracks cannot be ensured
Solution Approach 1:
Electrically insulating means are positioned between adjacent conductor tracks to serve as intermediaries that provide both mechanical support and electrical insulation. These insulating elements allow the tracks to be supported on each other structurally while preventing electrical contact, thus maintaining both simplicity and reliability.
Solution Approach 2:
The electrically insulating means perform multiple functions simultaneously: they provide mechanical support between conductor tracks, ensure electrical insulation, and allow relative movement between tracks. This multi-functionality eliminates the need for separate stabilization components, achieving both structural simplicity and electrical reliability.
3Stability of the object's composition
If a central guide rod and cap are used to stabilize the phase conductor, then mechanical stability is improved, but the device becomes more complex and expensive
Solution Approach 1:
The invention extracts and eliminates the central guide rod and cap from the phase conductor structure. Instead of adding stabilization components, the solution relies on the mutual support of conductor tracks through electrically insulating means, achieving mechanical stability without complex additional structures.
Solution Approach 2:
The conductor tracks support each other mutually through electrically insulating means, creating a self-stabilizing structure. Each track contributes to the overall mechanical stability of the phase conductor without requiring external stabilization components like guide rods or caps, achieving stability through self-service.

Function Achieved in This Case
The solution simplifies the structure while maintaining mechanical stability and electrical insulation, allowing for efficient heat dissipation and improved current carrying capacity, with reduced mechanical stress and cost.
Implementation Method 1
The electrically insulating fluid should preferably be enclosed within a housing, with the fluid-insulated phase conductor located at least partially within this housing. This allows the phase conductor to be surrounded, or even flushed, by the electrically insulating fluid.
Implementation Method 2
In addition to its electrically insulating effect, the electrically insulating fluid can also be used to cool the fluid-insulated phase conductor.
Implementation Method 3
faults can be automatically cleared by the fluid's turbulence
Implementation Method 4
The encapsulation housing should preferably be hermetically sealed so that the electrically insulating fluid cannot escape from the encapsulation housing or be contaminated by other media.
Implementation Method 5
supporting the conductor tracks on each other via support surfaces which are protected from direct contact with each other by an electrically insulating means
