Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the battery cell is placed on a rotary platform and driven to rotate for scanning, then the detection process can be completed, but the battery cell is prone to damage due to rotation

Engineering Contradiction:

Improvedetection efficiencyVSAvoidcell damage

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

Instead of rotating the battery cell to achieve detection of different portions, the patent inverts the approach by keeping the cell stationary and rotating the detection device (optical machine) around the cell. This eliminates the harmful rotational forces on the cell while maintaining the ability to detect all portions of the cell.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The detection process is segmented into multiple detection stations, each responsible for detecting specific portions of the battery cell. The first transfer device handles portions on one side while the second transfer device handles portions on the other side, allowing simultaneous detection without rotating the cell.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If the optical machine stops beams multiple times to load and unload battery cells, then the detection process can accommodate multiple cells, but the detection efficiency becomes low

Engineering Contradiction:

Improvemulti-cell handling capabilityVSAvoiddetection efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent implements continuous detection by having multiple detection stations operating simultaneously. While one battery cell is being detected at one station, another cell can be loaded or unloaded at a different station, eliminating the need to stop the detection beam and maintaining continuous productive action.

Inventive Principle:

Principle #20Continuity of useful action

Solution Approach 2:

Multiple detection functions are merged into a single integrated system with multiple detection stations arranged around the conveying path. This allows simultaneous detection of multiple cells at different stages, improving overall efficiency while maintaining adaptability.

Inventive Principle:

Principle #5Merging (Combining)

3Stability of the object's composition

If the battery cell is placed on a conveyor belt and moves multiple times to complete detection of four ends, then the position remains relatively fixed, but the detection efficiency becomes low

Engineering Contradiction:

Improvecell position stabilityVSAvoiddetection efficiency

Core Design Contradiction:

Stability of the object's compositionVSProductivity

Solution Approach 1:

Instead of moving the battery cell multiple times along the conveyor belt to detect different ends, the patent inverts the approach by keeping the cell stationary on the conveyor belt and rotating the detection device around the cell. This maintains position stability while dramatically improving detection efficiency.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The detection system transitions from a one-dimensional linear detection approach (moving cell along conveyor) to a two-dimensional radial detection approach (rotating detector around stationary cell), allowing all four ends to be detected in a single rotational cycle without moving the cell.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
