Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional fixing bracket with multiple bracket bodies and fasteners is used, then the cooling fin group can be securely fastened to the motherboard, but the bracket structure becomes large and complex, reducing motherboard area utilization and increasing material costs

Engineering Contradiction:

Improvefastening reliabilityVSAvoidbracket structure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges two separate bracket bodies into a single integrated bracket body with two pivoting points. This single bracket body contains both the first and second pivoting points, and the connecting rod assembly connects these pivoting points to simultaneously control two elastic buckling arms, achieving the fastening function of what would traditionally require two separate brackets while reducing structural complexity and material usage

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The single bracket body serves multiple functions by providing both the first and second pivoting points that control different elastic buckling arms. The connecting rod assembly acts as a universal connector that transmits motion from one pivoting point to another, allowing one bracket structure to perform the fastening function for multiple cooling components that would traditionally require separate brackets

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If a conventional fixing bracket with two opposite bracket bodies is used, then the cooling fin group can be fixed securely, but the overall size of the fixing bracket increases, reducing the utilization rate of motherboard area

Engineering Contradiction:

Improvefixation stabilityVSAvoidmotherboard area utilization

Core Design Contradiction:

ReliabilityVSArea of stationary object

Solution Approach 1:

The patent combines two opposite bracket bodies into one integrated bracket body that spans across the cooling fin group. This single bracket body has pivoting points on opposite sides and uses a connecting rod assembly to coordinate the movement of elastic buckling arms on both sides, achieving secure fixation while occupying less motherboard area than two separate brackets would require

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If a conventional fixing bracket with multiple structural parts is used, then the cooling fin group can be fastened reliably, but the material costs and assembly complexity increase

Engineering Contradiction:

Improvefastening reliabilityVSAvoidassembly simplicity

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent reduces the number of separate components by merging two bracket bodies into one. The single bracket body is manufactured as one piece with integrated pivoting points, and the connecting rod assembly serves as a single motion-transmitting component that coordinates both elastic buckling arms, simplifying both manufacturing and assembly compared to assembling two separate brackets with their own fasteners

Inventive Principle:

Principle #5Merging (Combining)
