Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If special tools like insulation strippers are used to connect tracer wire to terminals, then reliable electrical connection is achieved, but installation time increases and complexity increases

Engineering Contradiction:

Improveelectrical connection reliabilityVSAvoidinstallation time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent extracts the insulation stripping function from the connection process by incorporating a piercing mechanism that penetrates the insulation jacket directly. This allows the connection to be made through the insulation without requiring separate stripping tools, thereby reducing installation time while maintaining reliable electrical contact.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent combines multiple functions into a single terminal structure: the terminal simultaneously provides mechanical support, electrical contact, and insulation piercing capability. By merging these functions into one integrated component, the patent eliminates the need for separate insulation stripping tools and simplifies the installation process.

Inventive Principle:

Principle #5Merging (Combining)

2Ease of operation

If tracer wire connections are made accessible at the access point, then ease of operation is improved, but security against tampering deteriorates

Engineering Contradiction:

Improveconnection accessibilityVSAvoidtampering vulnerability

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent employs a nested structure where the terminal and connection components are housed within a secure access point enclosure. The connection mechanism is nested inside the protective housing, which can be locked or secured, thereby preventing unauthorized access while maintaining the ability to perform legitimate operations when needed.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Adaptability or versatility

If multiple tracer wires are connected to separate terminals, then versatility is improved, but device complexity increases

Engineering Contradiction:

Improvemulti-terminal capabilityVSAvoidaccess point structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements universal terminals that can accommodate multiple tracer wires with a standardized design. Each terminal is designed to accept tracer wires with insulation jackets of various thicknesses and materials, providing versatile functionality across different applications while maintaining a consistent, manageable structure.

Inventive Principle:

Principle #6Universality (Multi-functionality)
