Solution Overview

Problem

Current vehicle distribution processing systems face high communication costs due to reliance on cellular communication, which increases expenses with increased communication volume.

Innovation Solution

The information processing device employs direct wireless communication, such as vehicle-to-vehicle communication or communication with fixed APs using narrowband wireless systems like Wi-Fi or RSU, to distribute processing tasks, thereby reducing communication costs by avoiding pay-as-you-go billing systems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If cellular communication is used for vehicle distribution processing, then task processing capability is improved, but communication cost increases

Engineering Contradiction:
Improvetask processing capabilityVSAvoidcommunication cost
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The patent introduces a roadside unit (RSU) as an intermediary device that enables wireless communication between vehicles and the cloud server. This intermediary allows task distribution and data transmission without relying on cellular networks, thereby maintaining productivity while eliminating communication costs associated with cellular pay-as-you-go billing systems.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If communication volume increases to improve task processing, then processing efficiency is improved, but communication expense increases

Engineering Contradiction:
Improveprocessing efficiencyVSAvoidcommunication expense
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The RSU serves as a local communication hub that enables high-volume data transmission between vehicles and the cloud server without incurring cellular communication expenses. This intermediary infrastructure allows processing efficiency to scale with communication volume while maintaining zero communication cost for the vehicle-mounted information processing device.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Loss of energy

If direct wireless communication is used, then communication cost is reduced, but communication range may be limited

Engineering Contradiction:
Improvecommunication costVSAvoidcommunication range
Core Design Contradiction:
Loss of energyVSLength of stationary object

Solution Approach 1:

The roadside unit (RSU) acts as a communication intermediary that extends the effective communication range. By positioning the RSU at strategic locations along the vehicle's path, the system enables direct wireless communication over extended distances without relying on cellular networks, thus maintaining cost reduction while expanding communication range.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent transitions from direct vehicle-to-cloud communication to a multi-hop communication architecture involving roadside units. This dimensional change in communication topology allows vehicles to communicate with the cloud server through intermediate RSUs, effectively extending communication range while maintaining the benefits of non-cellular communication channels.

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