Solution Overview

Problem

In vehicles with multiple inlets, existing charging control units do not communicate with each other, leading to signal interference and difficulties in recognizing the charging state of other inlets, which can result in incomplete user intention identification.

Innovation Solution

A charging integrated controller with multiple inlets and control units that communicate with each other to determine a communication frequency occupied band for each inlet, avoiding signal interference by selecting non-overlapping frequency bands and using filters to classify and allocate signals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple charging control units are used for multiple inlets, then charging capability is improved, but signal interference occurs between control units

Engineering Contradiction:

Improvecharging capabilityVSAvoidsignal interference

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent divides the charging system into multiple independent control units, each responsible for a specific inlet. This segmentation allows each control unit to operate independently while maintaining overall system functionality, resolving the signal interference issue by isolating control functions.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a communication frequency management mechanism as an intermediary between multiple control units. This intermediary coordinates frequency allocation and prevents signal interference by ensuring that control units operate on non-conflicting frequencies.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If multiple charging control units operate independently, then charging flexibility is improved, but recognition of other inlets' charging state becomes difficult

Engineering Contradiction:

Improvecharging flexibilityVSAvoidcharging state recognition

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent implements a feedback mechanism where each charging control unit communicates charging state information to a central controller or other control units. This feedback loop ensures that all control units have awareness of the overall charging status, enabling coordinated operation and accurate user intention identification.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent creates a universal communication protocol that allows control units to exchange information about charging states. This multi-functional communication system enables control units to not only control their respective inlets but also recognize and respond to the charging states of other inlets.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If multiple independent controllers are used, then charging control capability is improved, but device complexity and material cost increase

Engineering Contradiction:

Improvecharging control capabilityVSAvoidnumber of controllers

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges multiple charging control functions into an integrated controller that manages multiple inlets through a unified architecture. This consolidation reduces the total number of separate controllers while maintaining the ability to independently control each inlet, thereby reducing device complexity and material costs.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The integrated controller is designed with multi-functional capabilities to handle multiple inlets simultaneously. By creating a universal controller that can manage diverse charging scenarios through a single unit, the system achieves high adaptability without proportionally increasing the number of controllers.

Inventive Principle:

Principle #6Universality (Multi-functionality)
