Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple special terminals are provided for different connections (screw terminals, spring terminals, plug-in connectors), then connection versatility is improved, but device complexity and manufacturing cost increase

Engineering Contradiction:
Improveconnection versatilityVSAvoidterminal complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal terminal structure that can accommodate multiple connection types (screw connections, spring connections, and plug-in connector connections) through a single integrated design. The terminal includes a receiving space with different connection regions that can adapt to various cable types and connector formats, eliminating the need for multiple specialized terminals while maintaining connection versatility

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

Solution Approach 2:

The terminal is divided into functional segments including a first connection region for screw/spring terminals and a second connection region for plug-in connectors. This segmentation allows each region to be optimized for its specific connection type while being integrated into a unified terminal structure, reducing overall device complexity

Inventive Principle:
Principle #1Segmentation

2Productivity

If dedicated connection systems like LINECT connectors are introduced to reduce mounting time, then connection speed is improved, but device complexity and part quantity increase

Engineering Contradiction:
Improvemounting speedVSAvoidconnection system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent merges the dedicated connection system functionality directly into the terminal structure by integrating a receiving space that accommodates plug-in connectors. This integration eliminates the need for separate dedicated connection systems while maintaining the rapid connection capability, as the plug-in connector can be directly inserted into the terminal's receiving space without additional components

Inventive Principle:
Principle #5Merging (Combining)

3Volume of moving object

If the electronic device is made flat or slim to meet design requirements, then device compactness is improved, but terminal size and cable connection capability are restricted

Engineering Contradiction:
Improvedevice sizeVSAvoidterminal capability
Core Design Contradiction:
Volume of moving objectVSAdaptability or versatility

Solution Approach 1:

The patent utilizes three-dimensional space efficiently by creating a receiving space within the terminal structure that can accommodate plug-in connectors and cables of various sizes. The terminal design incorporates vertical and lateral dimensions for cable reception while maintaining a compact footprint, allowing the device to remain slim while supporting versatile cable connections through optimized spatial arrangement

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
