Solution Overview

Problem

Existing spinning devices face challenges in securely and easily attaching the channel plate adapter to the rotor housing cover, leading to potential damage and operational interruptions due to complex fixation methods and susceptibility to vibrations and forces during spinning operations.

Innovation Solution

A spinning device with a spring-loaded locking bolt that automatically moves from a release position to a locking position, providing a self-locking mechanism for the channel plate adapter, ensuring secure and vibration-resistant attachment without the need for additional manual intervention or complex structures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If screw bolts are used to fix the channel plate adapter, then the adapter can be securely attached, but the fixing process becomes complicated and time-consuming requiring tools

Engineering Contradiction:
Improvesecure attachmentVSAvoidfixing process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the traditional screw bolt mechanical fastening system with a magnetic field-based fixing system. The channel plate adapter contains magnetic elements that are attracted to corresponding magnetic elements in the rotor housing cover, eliminating the need for screw bolts and manual tool-based fastening while maintaining secure attachment during high-speed spinning operations.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If magnetic fixing is used for the channel plate adapter, then the attachment process is simplified, but the adapter can be displaced or detached under high forces during spinning

Engineering Contradiction:
Improveattachment process simplicityVSAvoidattachment stability under force
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent combines multiple magnetic elements distributed across the channel plate adapter and rotor housing cover to create a distributed magnetic field system. This merging of multiple magnetic fixation points working together provides sufficient total magnetic force to securely hold the adapter during high-speed spinning while maintaining simple operation for attachment and removal.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If pivotable fixing elements are used to secure the adapter, then the adapter can be fixed, but the design becomes complex and the fixing can be unintentionally opened by vibrations

Engineering Contradiction:
Improveadapter fixationVSAvoiddesign complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical pivotable fixing element system with a magnetic field-based fixing system. The magnetic attraction force provides continuous securing without moving parts that could be accidentally opened by vibrations, eliminating the complexity of pivot levers and mechanical locking mechanisms while maintaining reliable fixation during spinning operations.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
