Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manual splicing and soldering techniques are used to couple high-speed data cables with diagnostic conductors, then flexibility in connection methods is provided, but the manufacturing complexity and cost increase significantly

Engineering Contradiction:
Improveconnection method flexibilityVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple separate connection operations (splicing, soldering, terminal attachment) into a single integrated connector module. The PCB serves as a common platform that simultaneously provides mechanical support, electrical connection, and structural integrity, eliminating the need for separate manual assembly steps while maintaining connection flexibility.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The PCB acts as an intermediary component between the high-speed data cable and the diagnostic header interface. It provides a standardized intermediate platform that simplifies the connection process by offering pre-defined connection points and pathways, reducing the complexity of direct cable-to-conductor coupling.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If manual splicing and soldering techniques are used to couple high-speed data cables with diagnostic conductors, then connection customization is enabled, but production cost and manufacturing difficulty increase

Engineering Contradiction:
Improveconnection customizationVSAvoidproduction cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The connector module is pre-assembled with all necessary connections (data cable terminals, diagnostic header interfaces, and internal PCB traces) established before installation. This preliminary configuration allows for customization without requiring complex manual assembly during production, as the module can be manufactured once and then easily installed in various applications.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system is divided into separate functional modules: the connector module with integrated PCB, the diagnostic header interface, and the high-speed data cable. This segmentation allows each component to be manufactured independently using optimized processes, reducing overall production cost while maintaining customization capability through modular assembly.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If traditional splicing and soldering connections are used, then connection flexibility is maintained, but connection reliability decreases due to unintended disconnect

Engineering Contradiction:
Improveconnection flexibilityVSAvoidconnection reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

Multiple connection functions are merged into the single connector module structure. The PCB provides both mechanical support and electrical connection simultaneously, creating a more reliable integrated solution compared to separate splicing and soldering operations. The unified structure reduces the number of potential failure points while maintaining installation flexibility.

Inventive Principle:
Principle #5Merging (Combining)

4Object-affected harmful factors

If traditional connection methods with protective covers are used, then basic protection is provided, but durability against pull force is insufficient

Engineering Contradiction:
Improvebasic protectionVSAvoidpull force resistance
Core Design Contradiction:
Object-affected harmful factorsVSStrength

Solution Approach 1:

The connector module employs a composite construction combining rigid PCB material with reinforced housing structure. This composite design provides both basic protection and enhanced mechanical strength to withstand pull forces, overcoming the limitations of simple protective covers while maintaining connection accessibility.

Inventive Principle:
Principle #40Composite materials
