Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the bottom plate thickness is increased to ensure structural strength, then the structural strength is improved, but the weight and carbon consumption increase

Engineering Contradiction:
Improvestructural strengthVSAvoidweight
Core Design Contradiction:
StrengthVSWeight of moving object

Solution Approach 1:

The patent changes the geometric parameters of the plate by introducing embossing structures that create recesses in the support surface. These recesses modify the moment of inertia of the plate's cross-sections, allowing the plate to achieve enhanced structural strength without increasing material thickness or weight. The specific design of the embossing structures optimizes the distribution of material to improve bending resistance while maintaining lightweight construction.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent introduces a third dimension by creating embossing structures with recesses that extend vertically from the support surface. This vertical dimension allows the plate to gain structural strength through geometric configuration rather than simply increasing thickness in the horizontal plane. The recesses create a more complex three-dimensional cross-sectional geometry that improves moment of inertia without adding material volume.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Strength

If the bottom plate thickness is increased to ensure structural strength, then the structural strength is improved, but the carbon consumption increases

Engineering Contradiction:
Improvestructural strengthVSAvoidcarbon consumption
Core Design Contradiction:
StrengthVSLoss of substance

Solution Approach 1:

The patent modifies the geometric parameters by incorporating embossing structures with recesses that optimize the moment of inertia of the plate's cross-sections. This allows the plate to achieve superior structural strength without increasing the amount of material used, thereby reducing carbon consumption associated with material production and manufacturing.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent utilizes vertical dimension through embossing structures to enhance structural strength without increasing horizontal material consumption. The recesses create a three-dimensional geometry that improves bending resistance and structural integrity while maintaining the same material footprint, thus reducing carbon consumption.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Strength

If embossing structures are added to improve structural strength, then the downward bending deformation is reduced, but the manufacturing complexity increases

Engineering Contradiction:
Improvedownward bending deformation resistanceVSAvoidmanufacturing complexity
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The patent employs embossing structures with specifically designed recesses that can be formed through standard stamping or molding processes. By optimizing the geometry of these recesses, the patent achieves improved resistance to downward bending deformation while maintaining compatibility with conventional manufacturing methods, thus limiting the increase in manufacturing complexity.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates vertical recesses through embossing that can be integrated into existing manufacturing workflows. The three-dimensional geometry is achieved through vertical stamping or molding operations rather than complex multi-step processes, making the enhancement of bending resistance achievable with moderate increases in manufacturing complexity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

A plate includes a support portion and at least one embossing structure. The support portion has a support surface. The embossing structure is formed on the support surface. Times of an average moment of inertia of cross sections of the plate in a first direction fall within a range from 1.14 to 1.18.
