Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple independent containers are used for different battery models, then battery formation can be performed for different models, but the device complexity increases and model changing becomes complex

Engineering Contradiction:
Improvebattery model adaptabilityVSAvoidmodel changing complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent employs a universal positioning block design that can accommodate multiple battery models through adjustable positioning holes and connecting assemblies. Instead of using separate containers for different models, a single device structure with configurable positioning blocks serves multiple battery types, thereby reducing device complexity while maintaining model adaptability

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

Solution Approach 2:

The positioning block is divided into multiple functional segments including positioning holes, connecting assemblies, and adjustable components. This segmentation allows each part to be independently configured for different battery models, enabling easy model changes without reassembling the entire negative pressure mechanism

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If complex assembly and disassembly procedures are used for model changes, then different battery models can be accommodated, but the battery formation efficiency decreases

Engineering Contradiction:
Improvemodel changing capabilityVSAvoidbattery formation efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The positioning blocks are pre-configured with multiple positioning holes and connecting assemblies in various positions during manufacturing. This preliminary arrangement allows operators to quickly select and adjust to different battery models by simply repositioning components rather than performing complex assembly and disassembly procedures, thereby improving battery formation efficiency while maintaining model adaptability

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If multiple independent containers are used, then each battery model can be processed independently, but the space occupation increases

Engineering Contradiction:
Improvemulti-model processing capabilityVSAvoiddevice space occupation
Core Design Contradiction:
Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

The patent merges multiple independent container functions into a single integrated device structure. By combining the negative pressure mechanism, positioning blocks, and connecting assemblies into one unified system, the device can process different battery models simultaneously or sequentially without requiring multiple separate containers, thereby reducing space occupation while maintaining multi-model processing capability

Inventive Principle:
Principle #5Merging (Combining)
