Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual cutting method is used to dismantle power battery modules, then operation flexibility is maintained, but safety hazards increase due to potential injury from cutters and burrs

Engineering Contradiction:
Improveoperation flexibilityVSAvoidsafety hazards
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent replaces manual mechanical cutting operations with an automated cutting device that uses a cutting blade to automatically cut through the housing of power battery modules. The device includes a cutting platform, clamping mechanism, and cutting blade assembly that automatically performs the cutting operation without manual intervention, thereby eliminating safety hazards associated with manual cutter handling while maintaining operational efficiency

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a stripping mechanism as an intermediary component between the cutting blade and the battery cells. This mechanism includes stripping plates that automatically remove burrs generated during cutting and prevent them from causing injury. The intermediary stripping mechanism acts as a protective barrier that eliminates the harmful effect of burrs without interfering with the cutting operation

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If manual cutting method is used, then device complexity is low, but manufacturing precision deteriorates due to difficulty in controlling cutting depth

Engineering Contradiction:

Solution Approach 1:

The patent replaces manual cutting operations with an automated cutting device that incorporates a cutting blade mounted on a drive assembly. The automated system controls the cutting depth and position through mechanical guidance and drive mechanisms, ensuring consistent and precise cutting depth across different battery modules without requiring complex manual measurement and control procedures

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent employs a cutting blade assembly that can move vertically along the housing of the power battery module under automated control. The blade is driven by a drive assembly that allows dynamic adjustment of cutting depth and position, enabling precise cutting through different sizes and configurations of battery modules while maintaining manufacturing precision

Inventive Principle:
Principle #15Dynamics

3Device complexity

If manual cutting method is used, then device complexity is low, but productivity deteriorates due to restricted dismantling capability

Engineering Contradiction:

Solution Approach 1:

The patent replaces manual dismantling operations with an automated device that integrates cutting, clamping, and stripping functions. The automated cutting device can process multiple battery modules sequentially without manual intervention, significantly improving productivity while maintaining relatively simple device architecture through the use of standardized mechanical components

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent designs a universal cutting device that can handle power battery modules of different sizes and configurations. The device includes adjustable clamping mechanisms and vertically movable cutting blades that can accommodate various module dimensions, enabling a single device to perform multiple dismantling tasks and thereby improving overall productivity without requiring multiple specialized tools

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

4Manufacturing precision

If fixed cutting device is used, then manufacturing precision is maintained, but adaptability deteriorates as it cannot cut batteries of different sizes

Engineering Contradiction:

Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The patent employs a cutting blade assembly that can move vertically along the housing of the power battery module under automated control. The blade is driven by a drive assembly that allows dynamic adjustment of cutting depth and position, enabling precise cutting through different sizes and configurations of battery modules while maintaining manufacturing precision

Inventive Principle:

Solution Approach 2:

The patent designs a universal cutting device with adjustable clamping mechanisms and vertically movable cutting blades that can accommodate various module dimensions. The device maintains cutting precision through automated positioning systems while adapting to different battery sizes through adjustable components, thereby achieving both manufacturing precision and adaptability

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