A shaped block with recesses and projections is used to position and hold electric line sections along the track, allowing for continuous energy transfer through an alternating electromagnetic field without electrical contact, using materials like concrete or polymer concrete to support the vehicle and prevent electromagnetic interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If inductive energy transfer is used to continuously supply power to vehicles, then energy storage capacity can be reduced, but electromagnetic compatibility problems arise due to electromagnetic field interference
Solution Approach 1:
The patent introduces shaped blocks as intermediary components that physically position and support the electric lines along the track. These blocks act as mediators between the energy transfer system and the vehicle, providing mechanical support and precise positioning while minimizing electromagnetic interference through their material composition and geometric design that directs fields toward the vehicle receiver.
Solution Approach 2:
The patent modifies the physical and geometric parameters of the shaped blocks, including their dimensions, recess configurations, and material properties, to optimize both the mechanical positioning of electric lines and the electromagnetic field distribution. By changing these parameters, the system achieves efficient energy transfer while controlling electromagnetic field intensity to meet compatibility requirements.
2Ease of manufacture
If electric lines are laid directly along the track without structured support, then installation is simpler, but positioning precision and holding stability of line sections deteriorate
Solution Approach 1:
The patent divides the track infrastructure into segmented shaped blocks that are individually manufactured and then assembled along the track. Each block contains integrated recesses and projections designed to precisely position specific line sections. This segmentation allows for standardized manufacturing while achieving high positioning precision through the interlocking geometry of blocks and lines.
Solution Approach 2:
The shaped blocks serve multiple functions simultaneously: they provide mechanical support for the electric lines, ensure precise positioning through their geometric features, maintain holding stability along the track, and contribute to the overall structural integrity of the track system. This multi-functionality reduces the need for separate components while simplifying installation.
3Reliability
If conventional conductor rails are used in the ground, then energy transfer is reliable, but safety problems arise for pedestrians and vehicles
Solution Approach 1:
The patent replaces the conventional mechanical contact system (conductor rails requiring physical contact) with an inductive energy transfer system using electric lines positioned in shaped blocks. This substitution eliminates the need for direct electrical contact between the track and vehicle, thereby removing the safety hazards associated with exposed conductors while maintaining reliable energy transfer through electromagnetic induction.
4Reliability
If overhead lines are used for energy transfer, then continuous power supply is achieved, but aesthetic and historical preservation concerns arise in city centers
Solution Approach 1:
The patent transitions the energy transfer infrastructure from the aerial dimension (overhead lines) to the ground level dimension by embedding electric lines within shaped blocks along the track. This dimensional change allows continuous power supply to be delivered at ground level, eliminating the visual impact of overhead lines while preserving historical city centers and improving aesthetics.

AI summary
A shaped block for positioning and/or holding a plurality of line sections of one or more electric lines along the track of a vehicle includes a plurality of recesses and/or projections. Edges of the recesses and/or the projections each delimit a space for the line sections into which one of the line sections can be introduced, so that said line section extends through the space in a longitudinal direction of the space. The longitudinal directions of the spaces delimited by the edges of the recesses and/or by the projections extend essentially mutually parallel in a common plane.
