Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual adjustment of battery position is used, then detection can be performed, but detection difficulty and complexity increase

Engineering Contradiction:
Improvedetection operationVSAvoiddetection system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The detection assembly automatically moves along the first linear direction to detect multiple sets of battery cells without requiring manual intervention. The system performs self-positioning and self-detection, eliminating the need for manual battery position adjustment and reducing operational complexity.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The detection assembly is designed to be movable along the first linear direction relative to the transverse moving platform, enabling dynamic positioning to detect multiple battery cell sets. This dynamic capability replaces static manual adjustment with automated motion control.

Inventive Principle:
Principle #15Dynamics

2Stability of the object's composition

If fixed probe plate is used, then structure is stable, but probe replacement becomes difficult

Engineering Contradiction:
Improveprobe plate stabilityVSAvoidprobe replacement
Core Design Contradiction:
Stability of the object's compositionVSEase of repair

Solution Approach 1:

The probe plate is designed as a detachable component that can be separated from the support structure. This segmentation allows the probe plate to be easily removed and replaced when needed, while maintaining structural stability during detection operations through proper mounting mechanisms.

Inventive Principle:
Principle #1Segmentation

3Productivity

If detection assembly moves along linear direction, then multiple battery cells can be detected, but system complexity increases

Engineering Contradiction:
Improvedetection efficiencyVSAvoiddetection assembly complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The detection assembly serves multiple functions: it moves along the first linear direction to access different battery cell positions, houses multiple probe assemblies for simultaneous detection, and integrates with the transverse moving platform. This multi-functionality enables detection of multiple battery cells without proportionally increasing system complexity.

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

Solution Approach 2:

The detection assembly combines multiple probe assemblies into a single integrated unit that moves together along the first linear direction. By merging the detection functions and motion control into one assembly, the system achieves efficient multi-point detection without requiring separate mechanisms for each probe.

Inventive Principle:
Principle #5Merging (Combining)
