Solution Overview

Problem

The existing manufacturing process for superconducting coil devices involves a non-removable winding frame, which restricts the contact area between the refrigerant and the superconducting coil, leading to decreased cooling efficiency, increased refrigerant usage, and reduced space utilization within the coil.

Innovation Solution

A superconducting coil device with a removable winding frame, comprising an upper and lower flange, connecting rods, upper and lower fixing plates, and a detachable winding frame that supports the wound coil, allowing for efficient cooling and increased space utilization by removing the frame after winding.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a non-removable winding frame is used to support the coil during manufacturing, then the coil structure is maintained during winding, but the contact area between refrigerant and coil is restricted, decreasing cooling efficiency

Engineering Contradiction:

Improvecoil structure supportVSAvoidcooling efficiency

Core Design Contradiction:

StrengthVSTemperature

Solution Approach 1:

The winding frame is divided into multiple segments that can be detached from each other. The frame consists of several modular components that can be assembled during coil winding and then separated for removal, allowing the coil to be supported during manufacturing while enabling full refrigerant contact after manufacturing is complete

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The winding frame transitions from a static, permanent structure to a dynamic, removable structure. The frame is designed with detachable connections that allow it to be assembled when needed for coil support and disassembled when no longer needed, adapting its presence based on the manufacturing stage

Inventive Principle:

Principle #15Dynamics

2Strength

If a non-removable winding frame is used, then the coil can be supported during winding, but refrigerant consumption increases due to reduced cooling efficiency

Engineering Contradiction:

Improvecoil structure supportVSAvoidrefrigerant consumption

Core Design Contradiction:

StrengthVSQuantity of substance

Solution Approach 1:

The winding frame is segmented into detachable parts that can be removed after coil winding, allowing the refrigerant to access the entire coil surface area without obstruction, thereby reducing the quantity of refrigerant needed to achieve effective cooling

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The winding frame serves its temporary purpose during coil manufacturing and is then discarded (removed) from the system. This temporary structure is no longer needed once the coil is wound, and its removal recovers the full cooling efficiency, reducing ongoing refrigerant consumption

Inventive Principle:

Principle #34Discarding and recovering

3Strength

If a non-removable winding frame is used, then the coil is supported during manufacturing, but the inner space utilization of the coil is reduced

Engineering Contradiction:

Improvecoil structure supportVSAvoidinner space utilization

Core Design Contradiction:

StrengthVSVolume of moving object

Solution Approach 1:

The winding frame is divided into removable segments that can be detached after the coil is wound. This segmentation allows the frame to provide necessary support during manufacturing while being removable to maximize the inner space available for the coil and any additional components

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The winding frame is extracted from the final coil assembly after serving its manufacturing purpose. By removing the frame, the full inner volume of the coil is available for its intended function, whether that be magnetic field generation or other applications requiring maximum internal space

Inventive Principle:

Principle #2Taking out (Extraction)

4Strength

If a non-removable winding frame is used, then the coil can be wound with support, but wire consumption increases due to reduced space utilization

Engineering Contradiction:

Improvecoil structure supportVSAvoidwire consumption

Core Design Contradiction:

StrengthVSLoss of substance

Solution Approach 1:

The removable, segmented winding frame allows for optimized coil winding geometry. By removing the frame after winding, the coil can be designed with more efficient wire paths and tighter packing, reducing the total wire length needed to achieve the required magnetic field or electrical characteristics

Inventive Principle:

Principle #1Segmentation
