Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple pipes and tees are interconnected to spray fire extinguishing agent, then fire extinguishing coverage is improved, but assembly time increases and manufacturing efficiency deteriorates

Engineering Contradiction:
Improvefire extinguishing coverageVSAvoidassembly time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent merges multiple separate pipes and tees into a single integrated fire extinguishing agent supply member that extends along the battery modules. This integrated structure eliminates the need for multiple connection points between pipes and tees, significantly reducing assembly time while maintaining comprehensive fire extinguishing coverage across all battery modules.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If pipes and tees are interconnected to cover various battery rack sizes, then fire extinguishing adaptability is improved, but design flexibility deteriorates due to varying pipe lengths

Engineering Contradiction:
Improvefire extinguishing adaptabilityVSAvoiddesign complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The fire extinguishing agent supply member is designed as a universal structure that can accommodate different battery rack sizes and configurations. The supply member includes multiple nozzles positioned to cover various battery module arrangements, allowing a single design to serve multiple applications without requiring custom pipe length variations.

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

3Measurement precision

If fire extinguishing agent supply member is installed to match battery module positions, then fire extinguishing precision is improved, but positioning accuracy deteriorates

Engineering Contradiction:
Improvefire extinguishing precisionVSAvoidpositioning accuracy
Core Design Contradiction:
Measurement precisionVSManufacturing precision

Solution Approach 1:

The fire extinguishing agent supply member is pre-configured with nozzles positioned to correspond to standard battery module locations. This preliminary positioning during manufacturing ensures that when the supply member is installed, the nozzles are already aligned with the correct battery module positions, eliminating the need for complex on-site positioning adjustments and ensuring both precision and accuracy.

Inventive Principle:
Principle #10Preliminary action
