Solution Overview

Problem

In large-scale specimen handling systems, distinguishing and classifying abnormal specimens due to clogging or fluid volume issues at the unloading position is inefficient and prone to human error, as existing methods require comparison with external information media like personal computers or printed sheets.

Innovation Solution

A specimen rack equipped with a notification unit using a luminous body to visually indicate specimen conditions and a communication unit for transmitting information, allowing direct visual and intuitive identification of abnormal specimens without operator comparison to external media.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If specimen information is displayed on external media (personal computer screen or printed sheets), then information can be communicated to operators, but operator efficiency decreases and human error increases due to the need for manual comparison

Engineering Contradiction:
Improvespecimen identification accuracyVSAvoidoperator efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent introduces a communication unit as an intermediary device that directly transmits specimen information (ID, analysis status, abnormality type) from the analyzing device to the specimen rack. This eliminates the need for operators to manually compare information between external media and specimens, thereby improving both reliability and productivity

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The specimen rack is equipped with a notification unit that autonomously displays specimen information directly at the unloading position. This self-service approach allows the system to communicate specimen status without requiring operator intervention for information retrieval and comparison, thus enhancing both accuracy and efficiency

Inventive Principle:
Principle #25Self-service

2Productivity

If the number of specimen racks is increased to handle large volumes of specimens, then throughput increases, but the complexity of tracking and managing individual specimens increases

Engineering Contradiction:
Improvespecimen handling throughputVSAvoidspecimen tracking complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The communication unit establishes a feedback loop that continuously transmits specimen information from the analyzing device to the specimen rack. This real-time feedback mechanism enables automatic tracking of specimen status across multiple racks, managing complexity through automated information flow rather than manual tracking

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The notification unit creates a local copy of specimen information (ID, analysis status, abnormality type) directly on the specimen rack. This copying approach allows each rack to independently display its own specimen information without requiring centralized manual tracking, simplifying the management of large numbers of racks

Inventive Principle:
Principle #26Copying

3Ease of manufacture

If manual comparison methods are used to identify abnormal specimens, then no additional communication devices are needed, but the likelihood of artificial mistakes such as specimen switching increases

Engineering Contradiction:
Improvesystem simplicityVSAvoidspecimen classification accuracy
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The communication unit acts as a reliable intermediary that automatically transmits specimen information from the analyzing device to the specimen rack. This eliminates manual comparison operations that lead to human errors such as specimen switching, while the added complexity is minimal and focused solely on the communication function

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical/manual process of information comparison with an automated communication and notification system. The communication unit and notification unit work together to automatically display specimen information, substituting human manual comparison operations with automated electronic communication, thereby improving reliability

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