Solution Overview

Problem

Existing battery systems lack efficient methods for individually replacing and managing battery modules while maintaining charging cycle history data, leading to suboptimal utilization of battery capacity and increased costs due to unnecessary replacements.

Innovation Solution

A battery pack design that allows for individually replaceable battery modules with integrated recording elements to track charging cycles, coupled with a battery control module and management unit to optimize charging and discharging based on module condition, enabling independent replacement of modules and control units.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If battery modules are designed to be individually replaceable, then ease of operation and maintenance are improved, but device complexity increases due to separate control modules

Engineering Contradiction:
Improveease of replacementVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The battery pack is divided into independent battery modules that can be individually replaced. Each module contains its own recording element to track charging cycles, allowing modules to be serviced separately without affecting other modules or the control module.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The recording element is extracted from the control module and placed within each battery module. This extraction allows the battery modules to maintain their charging history data independently, enabling seamless replacement without data loss while keeping the control module simple and separate.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If recording elements are integrated into each battery module, then reliability of charging cycle tracking is improved, but manufacturing complexity increases

Engineering Contradiction:
Improvedata integrityVSAvoidmanufacturing complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The recording function is segmented from the central control module and distributed to individual battery modules. This segmentation ensures that each module maintains its own charging cycle history, guaranteeing data integrity even when modules are replaced independently.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Each battery module contains a copy of the recording functionality needed to track its own charging cycles. This copying approach distributes the data management capability across all modules, ensuring reliability without requiring complex centralized management.

Inventive Principle:
Principle #26Copying

3Ease of repair

If battery control module is separated from battery modules, then ease of repair is improved, but device complexity increases

Engineering Contradiction:
Improvemodular maintenanceVSAvoidsystem architecture
Core Design Contradiction:
Ease of repairVSDevice complexity

Solution Approach 1:

The system is segmented into independent battery modules and a separate control module. The control module communicates with multiple battery modules through standardized interfaces, allowing the control module to be replaced or repaired without affecting the battery modules, and vice versa.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The control module is designed with universal communication capabilities to work with multiple battery modules. This multi-functionality allows a single control module to manage various modules without requiring module-specific control logic, simplifying the control module design while maintaining ease of repair.

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