Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a standardized connector device is used for all device variants, then manufacturing efficiency is improved, but adaptability to different device configurations deteriorates

Engineering Contradiction:
Improvemanufacturing efficiencyVSAvoidadaptability to different device configurations
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The connector device is divided into modular components: a base body with N recesses, a cover, and optional interruption units. This segmentation allows the same base connector design to be configured for different device variants by selectively adding or removing interruption units, thereby maintaining manufacturing efficiency while achieving adaptability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connector device incorporates movable interruption units that can be inserted or removed from the N recesses depending on the required configuration. This dynamic reconfigurability enables a single standardized connector design to adapt to different device variants, resolving the contradiction between standardization and customization.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If multiple electronic components are connected via the wiring harness, then device functionality is improved, but connector complexity increases

Engineering Contradiction:
Improvedevice functionalityVSAvoidconnector complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The base body with N recesses is designed as a universal connector that can accommodate different numbers and types of electronic components. The same base structure supports various configurations by selectively populating recesses with interruption units, thereby providing multi-functionality without increasing fundamental connector complexity.

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

3Reliability

If the wiring harness is designed for specific device variants, then connection reliability is improved, but manufacturing flexibility deteriorates

Engineering Contradiction:
Improveconnection reliabilityVSAvoidmanufacturing flexibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The base connector device is pre-configured with N recesses designed to accommodate interruption units. This preliminary preparation allows for reliable connections while maintaining manufacturing flexibility, as the interruption units can be selectively added or removed during assembly based on the specific device variant requirements.

Inventive Principle:
Principle #10Preliminary action
