Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate RF connector pins and I/O pins are used with alignment and soldering processes, then reliable electrical connections are achieved, but assembly complexity and manufacturing cost increase

Engineering Contradiction:

Improveelectrical connection reliabilityVSAvoidassembly process complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines separate RF connector pins and I/O pins into a single integrated array of electrical leads. This merging eliminates the need for separate alignment and soldering processes for different pin types, reducing assembly complexity while maintaining reliable electrical connections through a unified connection interface.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The array of electrical leads serves multiple functions simultaneously - it provides both RF video signal transmission and I/O data connections. This multi-functional design eliminates the need for separate specialized connectors, simplifying the overall assembly process while ensuring reliable connections for both signal types.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If separate RF connector and I/O pins are used, then distinct signal paths are maintained, but manufacturing time and cost increase

Engineering Contradiction:

Improvesignal transmission qualityVSAvoidmanufacturing efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent merges separate RF and I/O connection structures into a single integrated array of electrical leads. This consolidation reduces manufacturing steps by eliminating separate soldering operations and alignment procedures, thereby improving productivity while maintaining distinct signal paths through proper electrical isolation within the array.

Inventive Principle:
