Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If soldering processes are used to connect terminals in socket modules, then electrical connections can be established, but assembly time increases and potential sources of error arise

Engineering Contradiction:
Improvequality of electrical connectionsVSAvoidassembly time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces the soldering process (thermal/chemical joining method) with a mechanical connection system consisting of connecting elements that have contact areas for positive and/or frictional engagement with terminals. This mechanical substitution eliminates the need for soldering while maintaining reliable electrical connections, thereby reducing assembly time and eliminating soldering-related errors.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent extracts the soldering process entirely from the assembly procedure by introducing separate connecting elements that mechanically bridge terminals. The connecting elements are pre-formed with contact areas that engage with terminals through positive locking and/or friction, removing the time-consuming soldering step while preserving electrical connectivity.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If soldering processes are used to ensure connection durability, then electrical connections can withstand temperature fluctuations, but assembly complexity and time increase

Engineering Contradiction:
Improvedurability of electrical connections under temperature fluctuationsVSAvoidassembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the complex soldering process with a simpler mechanical connection system using connecting elements that engage terminals through positive locking and/or friction. This mechanical system achieves comparable or superior durability under temperature fluctuations while significantly reducing assembly complexity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The connecting elements are designed with dynamic characteristics that allow them to accommodate thermal expansion and contraction of terminals during temperature fluctuations. The frictional and positive locking mechanisms maintain reliable electrical connections despite dimensional changes, providing durability without requiring complex thermal compensation designs.

Inventive Principle:

Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the functions of multiple connecting cables into integrated connecting elements that directly bridge terminals within the housing. These connecting elements incorporate multiple contact areas that simultaneously establish multiple electrical connections, eliminating the need for separate cables and reducing overall component count while maintaining complete electrical connectivity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The connecting elements serve multiple functions: they provide mechanical support, establish electrical connections through multiple contact areas, and accommodate thermal variations. This multi-functionality replaces what would otherwise require multiple specialized components including several connecting cables, terminals, and mounting fixtures.

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