Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for electrically propellable vehicles struggle to efficiently manage power distribution across elongated road sections with mutually insulated conductor strips, requiring vehicle adaptations and precise length matching, which limits continuous energy supply and flexibility.
Innovation Solution
A rail structure with parallel tracks, each track having a voltage-carryable conductor surface supported by insulating layers, connected to external power sources, allowing vehicles to use onboard motors and control circuits to manage power from multiple sources, including batteries and external power stations, with contact collectors that adjust position dynamically for optimal energy transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conductor strips are mutually insulated across road sections, then power distribution control is improved, but continuous energy supply is limited due to length matching requirements
Solution Approach 1:
The patent introduces an intermediary coupling mechanism that bridges insulated conductor strips across road sections. This coupling device maintains electrical continuity while respecting the insulation boundaries, allowing power to flow continuously without requiring precise length matching of individual sections. The intermediary element resolves the contradiction by providing a controlled pathway through the insulation barriers.
Solution Approach 2:
The system segments the power distribution into controlled sections with insulation barriers, yet maintains overall continuity through selective coupling. This segmentation allows independent control of power distribution to different road sections while the coupling mechanism ensures continuous energy supply to the vehicle as it moves across sections, resolving the contradiction between controlled distribution and continuous supply.
2Manufacturing precision
If road sections require precise length matching, then power transfer precision is improved, but system flexibility is reduced
Solution Approach 1:
The patent employs dynamic coupling mechanisms that can adapt to varying road section lengths and configurations. Rather than requiring fixed, precisely matched sections, the system uses adjustable coupling devices that maintain proper electrical connection regardless of section length variations, thereby achieving power transfer precision without sacrificing system flexibility and adaptability.
Solution Approach 2:
The system allows parameters such as coupling position, contact pressure, and electrical impedance to be dynamically adjusted to optimize power transfer across road sections of varying lengths. This parameter adjustment capability enables precise power transfer while accommodating flexible road section designs without strict length matching requirements.
3Reliability
If multiple power sources are integrated, then energy supply reliability is improved, but power management complexity increases
Solution Approach 1:
The patent implements a universal power management system that can handle multiple power sources (onboard batteries, external power stations, and track-based power) through a single integrated control architecture. This multi-functional system automatically selects and manages appropriate power sources based on vehicle needs and available infrastructure, improving energy supply reliability while keeping the control system manageable through consolidation rather than proliferation of separate control mechanisms.
