Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If power cables, signal cables, and optical fiber cables are laid separately, then each cable can be optimized for its specific function, but the connection points become complex and prone to damage, reducing reliability and service life

Engineering Contradiction:
Improveconnection reliabilityVSAvoidconnection complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines power cables, signal cables, and optical fiber cables into a single composite cable structure. The cable core integrates multiple functional units (power line unit, data communication cable unit, optical cable unit) with a non-metallic reinforcement, eliminating the need for separate cable laying and reducing connection points that are prone to damage.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The composite cable serves multiple functions simultaneously within a single structure. It provides power transmission, data communication, and optical fiber transmission capabilities through integrated units, simplifying the overall system while improving reliability by reducing the number of separate connection points.

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

2Productivity

If traditional detection methods are used for cable faults, then the process is simple, but the detection efficiency is low and accuracy is not high, leading to long delays in fault handling

Engineering Contradiction:
Improvedetection efficiencyVSAvoiddetection system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent introduces a non-metallic reinforcement as an intermediary structural element within the cable core. This reinforcement provides a stable foundation for the integrated cable units and enables improved detection capabilities without requiring complex external detection systems, thereby improving detection efficiency while maintaining structural simplicity.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If separate cables are used for power and signal transmission, then each cable can be optimized independently, but the damaged parts are easy to break down after long-term use or environmental exposure, leading to short-circuit failure or fire accidents

Engineering Contradiction:
Improvecable durabilityVSAvoidenvironmental damage susceptibility
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent merges multiple cable functions into a single composite structure with a unified sheath assembly and water blocking layer. This integrated design protects all internal units (power, signal, optical) from environmental factors such as moisture and physical damage, preventing the breakdown issues that occur with separate cables exposed to the same environment.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The cable employs composite materials including a non-metallic reinforcement, water blocking layer, and sheath assembly that provide enhanced protection against environmental factors. These composite structures improve durability and resistance to breakdown from moisture and physical stress compared to traditional separate cable designs.

Inventive Principle:
Principle #40Composite materials
