Solution Overview

Problem

Existing superconductor electric cables require significant energy to maintain the necessary cooling temperatures, which is inefficient and can lead to operational issues such as local overheating and mechanical wear.

Innovation Solution

The electric cable design features a support body with internal flow ducts and grooves for coolant fluid to directly contact the superconductor strips, along with compression spacers to secure the strips and prevent movement, allowing for enhanced cooling efficiency and reduced energy consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If the CICC technique is used to cool the superconductor cables, then the superconductor materials can be maintained at critical temperatures, but a considerable quantity of energy is required for cooling

Engineering Contradiction:
Improvecritical temperature of superconductorVSAvoidenergy consumption for cooling
Core Design Contradiction:
TemperatureVSUse of energy by moving object

Solution Approach 1:

The patent embeds flow channels directly within the support body structure itself, nesting the cooling fluid passage inside the structural element. This eliminates the need for separate external cooling ducts and reduces the overall system complexity and energy requirements for cooling the superconductor cables.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The support body serves dual functions: providing mechanical support for the superconductor strips and simultaneously acting as the cooling structure with integrated flow channels. This self-service approach eliminates the need for separate cooling systems and reduces energy consumption.

Inventive Principle:
Principle #25Self-service

2Stability of the object's composition

If the support body is made rigid to securely hold the superconductor strips, then mechanical stability is improved, but flexibility for winding into coils is reduced

Engineering Contradiction:
Improvemechanical stability of support bodyVSAvoidflexibility for winding
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The support body is constructed from flexible material that can be wound into coils while maintaining its structural integrity. The flexibility of the material allows the support body to adapt to curved configurations without compromising its ability to securely hold the superconductor strips in place.

Inventive Principle:
Principle #30Flexible shells and thin films
