Innovation Solution

A plug with a housing featuring insulated electrical contact elements and a light-conducting optical contact element, arranged on a connector pin that can be manually inserted into a carrier body with electrically conductive layers and a light-conducting layer, allowing for easy connection and control of electrical and optical signals without the need for tools, using a control unit to manage signal transmission based on input light signals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a plug is designed to pierce multi-layered structures with multiple connecting pins, then connection capability to multiple layers is improved, but device complexity and difficulty of operation increase

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

Solution Approach 1:

The patent combines multiple connecting pins (first connecting pin for first conductive layer, second connecting pin for second conductive layer, and third connecting pin for light-conducting layer) into a single integrated plug body. This merging approach allows the plug to simultaneously establish electrical and optical connections to multiple layers through a single insertion action, thereby improving connection capability while avoiding the complexity of handling multiple separate pins individually.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The plug is designed as a universal connector that can simultaneously perform multiple functions: establishing electrical connection to the first conductive layer, electrical connection to the second conductive layer, and optical connection to the light-conducting layer. This multi-functional design enables a single plug to adapt to various connection requirements in multi-layered structures, enhancing versatility without proportionally increasing complexity.

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

2Reliability

If a plug requires tool-assisted insertion into carrier body, then connection reliability is improved, but ease of operation deteriorates

Engineering Contradiction:
Improveconnection reliabilityVSAvoidease of insertion
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The connecting pins are pre-configured with pointed tips during manufacturing, which enables them to automatically pierce through the carrier body material upon insertion. This preliminary preparation of the pin geometry eliminates the need for external cutting or drilling tools during installation, allowing users to directly insert the plug into the carrier body while maintaining reliable mechanical and electrical connections.

3Adaptability or versatility

If electrical contact elements are arranged at different longitudinal positions on connecting pin, then connection to multiple layers is improved, but manufacturing precision requirements increase

Engineering Contradiction:

Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The electrical contact elements are positioned at different longitudinal locations along the connecting pin, with each contact element optimized for its specific function and connection target. The first electrical contact element is positioned to engage with the first conductive layer, the second electrical contact element for the second conductive layer, allowing each contact to be precisely positioned for its specific connection requirement while maintaining overall manufacturing feasibility.
