Solution Overview

Problem

Conventional battery modules require multiple separate plates for protection, increasing the number of parts and complicating the coupling process, which is inefficient and cumbersome.

Innovation Solution

A battery module with an integrated casing that surrounds a cartridge assembly, featuring a hook member for easy coupling and decoupling of the casing and cover, reducing the number of parts and simplifying the coupling process through a method involving punching, bending, and bonding of a single plate.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate plates are used to protect battery cells, then protection function is provided, but the number of parts increases and coupling process becomes complicated

Engineering Contradiction:

Improveprotection functionVSAvoidnumber of parts and coupling process

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges multiple separate protection plates into a single integrated casing structure that surrounds the battery cartridge assembly. This unified casing eliminates the need for multiple separate plates and their complex coupling processes, while maintaining comprehensive protection functionality through its enclosing design.

Inventive Principle:

Principle #5Merging (Combining)

2Reliability

If multiple separate plates are used, then protection coverage is provided, but assembly and disassembly processes become time-consuming

Engineering Contradiction:

Improveprotection coverageVSAvoidassembly and disassembly time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

By combining multiple protection plates into one integrated casing, the patent enables the entire protection structure to be assembled and disassembled as a single unit, dramatically reducing the time required compared to assembling and disassembling multiple separate plates individually.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The casing incorporates a hook member that enables selective coupling and decoupling with the cover, allowing the protection structure to be quickly assembled and disassembled on demand, thus reducing assembly and disassembly time while maintaining protection coverage when needed.

Inventive Principle:

Principle #15Dynamics

3Strength

If separate plates are coupled together, then structural protection is achieved, but the coupling process becomes complicated

Engineering Contradiction:

Improvestructural protectionVSAvoidcoupling process

Core Design Contradiction:

StrengthVSEase of manufacture

Solution Approach 1:

The patent integrates multiple separate plates into a single molded casing structure, eliminating the need for complex coupling processes between multiple components. The unified structure maintains structural strength through its integrated design while simplifying manufacturing to a single molding and bonding operation.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The casing is pre-formed as an integrated structure through molding, with bonding parts and through parts built-in during manufacturing. This preliminary formation eliminates the need for complex assembly and coupling operations later, simplifying the manufacturing process while ensuring structural integrity.

Inventive Principle:

Principle #10Preliminary action
