Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional wired data transfer methods are used, then data can be transferred from the autonomous vehicle, but the process is time-consuming and inefficient

Engineering Contradiction:

Improvedata transfer efficiencyVSAvoiddata transfer time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent replaces the mechanical wired connection system with an electromagnetic wireless communication system. A high throughput antenna transmits data packets wirelessly to a receiver at the charging station, eliminating the need for physical cable connections and hard drive swapping, thereby significantly reducing data transfer time and improving efficiency

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The charging station is designed with dual functionality: it simultaneously charges the autonomous vehicle's battery and receives data packets from the vehicle's antenna. This multi-functional approach allows power transfer and data transfer to occur concurrently through the same infrastructure, maximizing productivity and eliminating sequential operation delays

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If hardwire connection is used for data transfer, then data can be transferred securely, but the method is complex and requires physical connections

Engineering Contradiction:

Improvedata transfer securityVSAvoidconnection complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent eliminates complex mechanical connection systems (cables, connectors, hard drive removal mechanisms) by substituting them with wireless electromagnetic communication. The high throughput antenna transmits encrypted data packets through the air to the charging station receiver, maintaining security through cryptographic protocols while dramatically simplifying the physical infrastructure

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The wireless communication system introduces an electromagnetic field as an intermediary medium for data transfer. Instead of direct physical contact between vehicle and charging station, data packets are transmitted through radio waves, reducing mechanical complexity while maintaining secure transfer through protocol-level authentication and encryption

Inventive Principle:

Principle #24Intermediary (Mediator)

3Loss of time

If data is transferred during charging, then time is saved, but wireless interference may occur between multiple vehicles

Engineering Contradiction:

Improvecharging and data transfer timeVSAvoidwireless interference

Core Design Contradiction:

Loss of timeVSObject-affected harmful factors

Solution Approach 1:

The patent segments the wireless communication spectrum into dedicated channels or time slots for different vehicles. By dividing the communication resources, multiple vehicles can simultaneously charge and transfer data without experiencing harmful interference, as each vehicle operates on its assigned frequency or time window

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system implements feedback mechanisms where the charging station monitors wireless signal quality and dynamically adjusts transmission parameters. When interference is detected from multiple vehicles, the system can modulate power levels, switch frequencies, or coordinate transmission timing to minimize harmful effects while maintaining efficient data transfer during charging

Inventive Principle:

Principle #23Feedback
