Solution Overview

Problem

Traditional dyeing devices for blood smears face inefficiencies due to reuse of dyeing solution affecting quality, resource waste, and high costs, particularly in multi-slide dyeing, while single-slide dyeing results in resource waste and low efficiency due to non-recyclable dyeing tanks.

Innovation Solution

A dyeing device with a transmission mechanism for circular movement within an enclosed delivery channel, equipped with a blocking and separating mechanism, reagent supplying and discharging mechanism, and a driving mechanism, allowing for the reuse of dyeing tanks by blocking, treating, and separating them for reagent injection or discharge.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multi-slide dyeing technology is used to process multiple smears simultaneously, then processing efficiency is improved, but dyeing solution quality deteriorates due to repeated reuse affecting diagnostic accuracy

Engineering Contradiction:

Improveprocessing efficiencyVSAvoiddyeing solution quality

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system segments the dyeing process into multiple work positions (loading, dyeing, discharging, washing) along a circular track, allowing multiple dyeing tanks to be processed simultaneously while maintaining separate, controlled environments for each batch, thus preserving solution quality while improving throughput

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system implements automatic discharge of used dyeing solution from each tank after a single use, and automatic refilling with fresh solution for the next cycle, eliminating the quality degradation caused by repeated reuse while maintaining continuous operation capability

Inventive Principle:

Principle #34Discarding and recovering

2Reliability

If single-slide dyeing technology is used to maintain dyeing solution quality, then dyeing quality is improved, but processing efficiency deteriorates due to sequential processing of each smear

Engineering Contradiction:

Improvedyeing qualityVSAvoidprocessing efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The system merges multiple single-slide dyeing tanks onto a single automated circular track with shared work positions, combining the quality control benefits of individual tank processing with the efficiency of parallel operation, allowing multiple smears to be dyed simultaneously without compromising quality

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The automated transmission mechanism ensures continuous circulation of dyeing tanks through all work positions without interruption, eliminating idle time between processing steps and maintaining constant productive operation across all tanks simultaneously

Inventive Principle:

Principle #20Continuity of useful action

3Reliability

If traditional single-slide dyeing tanks are used, then dyeing quality is maintained, but resource waste increases due to non-recyclable tanks

Engineering Contradiction:

Improvedyeing qualityVSAvoidresource waste

Core Design Contradiction:

ReliabilityVSLoss of substance

Solution Approach 1:

The dyeing tanks are equipped with automatic refilling capabilities that draw fresh solution from a central reservoir through the reagent supplying mechanism, allowing tanks to service themselves without manual intervention and enabling continuous reuse of the same physical tanks indefinitely, eliminating resource waste

Inventive Principle:

Principle #25Self-service

4Adaptability or versatility

If manual operation is used for traditional dyeing devices, then operational flexibility is maintained, but labor cost and time consumption increase

Engineering Contradiction:

Improveoperational flexibilityVSAvoidtime consumption

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system incorporates sensors and control mechanisms that automatically detect when tanks arrive at work positions, when dyeing cycles are complete, and when refilling is needed, providing real-time feedback to the control system to coordinate all operations automatically, eliminating manual monitoring while maintaining precise control over the dyeing process

Inventive Principle:

Principle #23Feedback

AI summary

A dyeing device of a smear machine may include a dyeing tank, a transmission mechanism and a work position set in an enclosed delivery channel of the transmission mechanism. The work position may include a blocking and separating mechanism, a reagent supplying and discharging mechanism, and a driving mechanism for driving the blocking and separating mechanism. The blocking and separating mechanism can operate for blocking a dyeing tank to be treated in a current work position, separating a treated dyeing tank and transmitting a separated dyeing tank to a next work position along the enclosed delivery channel. The reagent supplying and discharging mechanism can inject and/or discharge reagent into/from the dyeing tank. Various embodiments of this disclosure can transmit the dyeing tank within the enclosed transmission channel, block and separate the dyeing tank in the work position, and inject/discharge the dyeing solution into/from the dyeing tank as needed.
