Solution Overview

Problem

The existing transfer racks for yarn spindles are prone to shaking due to the long rods used for storing multiple spindles, making it difficult to quickly and accurately grasp the spindles for subsequent operations.

Innovation Solution

A transfer rack with a stabilizing mechanism and a pushing mechanism, including support beams and power components, that stabilize the hanging rods and goods during movement and removal, reducing shaking and improving efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If long rods are used for storing multiple yarn spindles, then the storage capacity is improved, but the stability of the rods deteriorates causing shaking

Engineering Contradiction:
Improvestorage capacityVSAvoidstability
Core Design Contradiction:
Quantity of substanceVSStability of the object's composition

Solution Approach 1:

The stabilizing mechanism divides the long hanging rod into multiple supported sections by introducing support beams at different positions, reducing the span between support points and minimizing shaking while maintaining full storage capacity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Support beams are introduced as intermediary elements between the hanging rod and the rack structure, providing additional support points that reduce rod deflection and shaking without affecting the storage function

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If one end of the rod is fixed, then the structure is simple, but the accessibility to yarn spindles deteriorates due to shaking at the free end

Engineering Contradiction:
Improvestructural complexityVSAvoidaccessibility
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The stabilizing mechanism is designed to be dynamically adjustable, with support beams that can be positioned at different locations along the rod based on the loading state, providing stability when needed while maintaining simplicity when the rod is empty

Inventive Principle:
Principle #15Dynamics

3Stability of the object's composition

If support beams are added to stabilize hanging rods, then the stability is improved, but the device complexity increases

Engineering Contradiction:
ImprovestabilityVSAvoiddevice complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The stabilizing mechanism serves multiple functions: it provides structural support to reduce shaking, enables the pushing mechanism to function effectively, and can be adjusted based on loading conditions, thereby justifying the added complexity through multifunctionality

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

4Productivity

If a pushing mechanism is added to move goods, then the productivity is improved, but the device complexity increases

Engineering Contradiction:
Improvedepositing and removal efficiencyVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The pushing mechanism is designed to work in conjunction with the stabilizing mechanism, where the support beams provide the necessary structural foundation that enables the pushing mechanism to operate effectively, reducing the overall system complexity

Inventive Principle:
Principle #25Self-service

AI summary

Provided is a transfer rack including a rack, a pushing mechanism, and a stabilizing mechanism. The rack includes a base (130), a vertical plate (110) and hanging rods (120). The hanging rods are hierarchically hanged above the base. The pushing mechanism includes a push plate (310) and a first power component (320) connected with the push plate. The push plate has through-holes matched with the hanging rods, the push plate is slidably arranged on the hanging rods through the through-holes, and the first power component is provided to drive the push plate to move the goods to be transferred. The stabilizing mechanism includes support pillars (210), support beams (220) and second power components (230). The support beams are lifted and lowered under driving of the second power components.
