Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a rack frame structure is used to support battery packs, then structural stability is improved, but device complexity and size increase

Engineering Contradiction:
Improvestructural stabilityVSAvoidstructure complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent removes the rack frame component from the battery container structure. Instead of using a separate rack frame to support battery packs, the design integrates support functions directly into the container walls and base, eliminating unnecessary structural elements while maintaining stability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The support function previously performed by the rack frame is merged with the container structure itself. The container walls and base are designed to directly support battery packs without requiring a separate rack frame, combining structural support and containment functions into a unified design.

Inventive Principle:
Principle #5Merging (Combining)

2Stability of the object's composition

If a rack frame structure is used to support battery packs, then structural stability is improved, but manufacturing efficiency deteriorates

Engineering Contradiction:
Improvestructural stabilityVSAvoidassembly efficiency
Core Design Contradiction:
Stability of the object's compositionVSProductivity

Solution Approach 1:

By removing the rack frame component entirely, the assembly process is simplified. Workers no longer need to install and secure a separate rack frame structure, reducing assembly steps and improving manufacturing efficiency while the container structure itself provides necessary support.

Inventive Principle:
Principle #2Taking out (Extraction)

3Stability of the object's composition

If brackets are not directly installed on corner columns, then structural stability is improved, but device complexity increases

Engineering Contradiction:
Improvestructural stabilityVSAvoidstructure complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The bracket installation is directly integrated with the corner columns. Brackets are mounted directly onto the corner columns without requiring intermediate support structures, merging the support function into the existing structural elements and simplifying the overall design.

Inventive Principle:
Principle #5Merging (Combining)

4Stability of the object's composition

If more structural components are used to ensure stability, then structural stability is improved, but energy density deteriorates

Engineering Contradiction:
Improvestructural stabilityVSAvoidenergy density
Core Design Contradiction:
Stability of the object's compositionVSQuantity of substance

Solution Approach 1:

By extracting and removing the rack frame component, the patent reduces the total volume occupied by non-active structural elements. This increases the relative volume available for battery packs, thereby improving energy density while the container structure maintains necessary stability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The container structure is designed to perform multiple functions simultaneously - containment, support, and protection - without requiring separate dedicated support structures. This integration maximizes the space available for energy-storing components, improving energy density.

Inventive Principle:
Principle #5Merging (Combining)
