Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If electric vehicles use battery power storage, then they can operate without fossil fuels, but the range is limited and charging infrastructure is scarce

Engineering Contradiction:
Improveenergy storage capacityVSAvoidcharging infrastructure availability
Core Design Contradiction:
Use of energy by moving objectVSReliability

Solution Approach 1:

The patent introduces magnetic lane marking components as an intermediary system between vehicles and charging infrastructure. These markings provide sensor feedback to guide vehicles to charging stations, effectively mediating the connection between limited battery capacity and scarce charging infrastructure by enabling reliable navigation to charging points.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system employs sensor feedback from specialized lane marking components to guide electric vehicles to charging stations. This feedback mechanism allows vehicles to locate and navigate to charging infrastructure reliably, addressing the scarcity problem by providing real-time directional information based on vehicle position and charging station locations.

Inventive Principle:
Principle #23Feedback

2Extent of automation

If autonomous vehicle systems use traditional navigation, then they can operate independently, but they face challenges in adverse weather conditions

Engineering Contradiction:
Improveautonomous navigation capabilityVSAvoidnavigation reliability in adverse weather
Core Design Contradiction:
Extent of automationVSReliability

Solution Approach 1:

The magnetic lane marking components serve as a reliable intermediary reference system that is not affected by adverse weather conditions. These markings provide consistent sensor feedback to autonomous vehicles, enabling reliable navigation and charging station location regardless of weather, thereby mediating between automation requirements and environmental challenges.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Measurement precision

If specialized lane marking components are deployed, then sensor feedback and navigation accuracy improve, but system cost increases

Engineering Contradiction:
Improvesensor feedback accuracyVSAvoidcharging system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The specialized lane marking components serve multiple functions: they provide navigation guidance, enable sensor feedback for vehicle localization, and guide vehicles to charging stations. This multi-functionality reduces the need for separate systems, thereby improving measurement precision while limiting the increase in overall system complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A system and method is provided for delivering electric energy to an electric vehicle via electric charging stations or kiosks where an energy delivery point is configured to provide energy to the electric vehicle via a connector or a wireless energy source. The method involves charging an electric vehicle by detecting, using a RFID tag reader associated with an electric vehicle, signals emanating from a marker positioned on the ground, where the marker includes one or more RFID tags, and where the RFID tag reader is able to recognize the signals despite weather conditions where the ground is covered by snow.
