Solution Overview

Problem

Existing roadways for electric vehicle energy transfer are not robust and require high maintenance, as they are prone to corrosion and damage from dirt, water, and vibrations, especially when used by road vehicles.

Innovation Solution

A route design using pre-fabricated shaped blocks to position and hold electric lines, covered by a robust material like asphalt or concrete, which integrates the blocks and lines into a single layer, reducing maintenance needs and protecting against environmental factors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If electric lines are laid directly in the roadway for inductive energy transfer, then energy transfer capability is improved, but the system becomes vulnerable to corrosion and damage from dirt, water, and vibrations

Engineering Contradiction:
Improveenergy transfer capabilityVSAvoidresistance to corrosion and damage
Core Design Contradiction:
Use of energy by moving objectVSReliability

Solution Approach 1:

The patent introduces shaped blocks as intermediary elements that hold the electric lines at elevated positions above the roadway surface. These blocks act as a mediator between the electric lines and the harsh environment, preventing direct contact with dirt and water while allowing inductive energy transfer to proceed through the blocks to vehicles traveling on the roadway.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent transitions the electric lines from a horizontal layout along the ground to a vertical arrangement where lines are positioned above the roadway surface on shaped blocks. This dimensional change elevates the electric lines away from harmful environmental factors while maintaining their functional relationship with moving vehicles.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of manufacture

If electric lines are exposed on the roadway surface, then installation and maintenance access is improved, but the system becomes prone to damage from vehicle traffic and environmental factors

Engineering Contradiction:
Improveinstallation and maintenance accessVSAvoidprotection against traffic and environment
Core Design Contradiction:
Ease of manufactureVSStrength

Solution Approach 1:

The patent divides the roadway structure into distinct segments: the roadway surface, shaped blocks positioned vertically, and electric lines mounted on the blocks. This segmentation allows each component to be independently installed and maintained while providing protective separation between the vulnerable electric lines and the traffic-bearing roadway surface.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The shaped blocks are pre-positioned vertically before the roadway surface is completed, creating a protected pathway for electric lines. This preliminary action ensures that the electric lines are already shielded from environmental damage and traffic effects before the full roadway structure is in place, facilitating future maintenance without requiring roadway disruption.

Inventive Principle:
Principle #10Preliminary action

3Duration of action of stationary object

If a robust cover material is used to protect electric lines, then durability is improved, but the complexity of integrating blocks and lines increases

Engineering Contradiction:
Improvedurability of energy transfer systemVSAvoidintegration complexity of blocks and lines
Core Design Contradiction:
Duration of action of stationary objectVSDevice complexity

Solution Approach 1:

The patent merges the shaped blocks and electric lines into a single integrated vertical assembly that functions as one unified structure. The blocks are designed with specific geometries that directly accommodate and secure the electric lines, eliminating the need for separate mounting hardware or complex integration steps while maintaining durability against environmental factors.

Inventive Principle:
Principle #5Merging (Combining)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The solution provides a durable and low-maintenance energy transfer system for vehicles, allowing them to drive over the electric lines without disrupting the energy transfer, while protecting against dirt, water, and vibrations, enhancing the robustness and durability of the roadway.

Implementation Method 1

If an alternating electric current flows through the electric lines, an electromagnetic field is produced that induces an electric current in a receiver of a vehicle which is travelling on the driving way.

Methodology Applied
Scientific EffectElectromagnetic induction: Electromagnetic Induction
