Solution Overview

Problem

Existing inductive vehicle charging systems lack an efficient method for updating the operating software of base modules, particularly in locations without network connections or mobile internet access.

Innovation Solution

A vehicle module with a state monitoring device, software managing device, and communication device that transmits and verifies software updates to base modules during charging, ensuring the base modules operate with the latest software versions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If base modules are updated via network connection, then software updates can be transmitted reliably, but the system cannot operate in locations without network access

Engineering Contradiction:
Improvesoftware update reliabilityVSAvoidoperational flexibility in various locations
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The vehicle module CPM downloads and stores software updates in advance when a network connection is available. The update is prepared and held in the vehicle module's memory before the actual charging session, so that when the vehicle arrives at a charging location without network access, the update is already ready to be transmitted to the base module during the charging process.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The vehicle module CPM acts as an intermediary between the remote server and the base module GPM. It receives the software update from the server when connected, stores it temporarily, then transfers it to the base module during inductive charging. This intermediary role enables update transmission in locations where the base module itself cannot directly access the network.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If software updates are transmitted during charging, then continuous operation is maintained, but the charging process must be coordinated with data transmission

Engineering Contradiction:
Improvecharging efficiencyVSAvoidcoordination complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent combines two functions into a single process: inductive energy transfer and software update transmission. Both the energy transfer and data transmission occur simultaneously through the same communication channel during the charging session, eliminating the need for separate update operations and maximizing the utilization of the charging time.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The software update transmission is integrated into the charging process itself, ensuring that the base module receives updates during periods when it is already powered and connected to the vehicle module. This continuous operation avoids interrupting the charging service and ensures that updates are applied without requiring additional downtime or separate maintenance sessions.

Inventive Principle:
Principle #20Continuity of useful action

3Adaptability or versatility

If the vehicle module stores software updates, then updates are available offline, but the vehicle module requires additional storage capacity

Engineering Contradiction:
Improveoffline update capabilityVSAvoidvehicle module storage volume
Core Design Contradiction:
Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

The vehicle module CPM stores only the software update data temporarily, not the complete software package with all associated files and metadata. The update is transmitted in a compressed or differential format that requires minimal storage space in the vehicle module, while still providing the full update capability when transferred to the base module.

Inventive Principle:
Principle #16Partial or excessive action
