Solution Overview

Problem

Current methods for storing and managing paraffin blocks of biological samples are inefficient, leading to errors, waste of time, and loss of samples due to manual handling and lack of appropriate storage solutions, especially with the increasing quantity of blocks from 200 million in the 1990s to 750 million by 2030, which exceeds the capacity of existing systems.

Innovation Solution

A computerized and automated storage system for paraffin blocks, featuring horizontal storage compartments with interlocking projections and recesses for vertical positioning, and automated reading and recording of identification information for precise location tracking, allowing for arbitrary placement and reducing the need for operator training.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual handling and storage methods are used for paraffin blocks, then storage simplicity is maintained, but errors, time waste, and sample loss increase significantly

Engineering Contradiction:
Improvestorage accuracyVSAvoidstorage system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The storage system enables self-service through automated identification reading and location tracking. When blocks are placed in compartments, the system automatically reads their identification information and records their positions without requiring manual data entry or operator intervention, thereby improving reliability while maintaining operational simplicity

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical handling with automated electronic identification and computerized tracking systems. Optical or RFID readers automatically detect block identifiers, and software systems track locations, substituting human-operated mechanical processes with automated electronic systems that eliminate errors and sample loss

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

2Quantity of substance

If existing storage systems are used, then current storage capacity is sufficient, but they cannot support the growing quantity of blocks projected to reach 750 million by 2030

Engineering Contradiction:
Improvestorage capacityVSAvoidsystem adaptability
Core Design Contradiction:
Quantity of substanceVSAdaptability or versatility

Solution Approach 1:

The storage system is divided into multiple independent compartments arranged in an organized grid pattern, allowing the system to be scaled by adding more compartments or modules. This segmentation enables the system to adapt to growing storage needs from current capacity up to 750 million blocks by 2030 without requiring a complete system replacement

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The storage compartments are designed with universal characteristics that can accommodate different types of paraffin blocks and identification systems. The standardized compartment design and flexible identification reading capabilities allow the same system to handle varying quantities and types of samples, providing adaptability as storage requirements evolve

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

3Measurement precision

If automated reading and recording systems are implemented, then precise location tracking is achieved, but device complexity increases

Engineering Contradiction:
Improvelocation tracking precisionVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The automated reading and recording functions are extracted as separate, modular components from the basic storage structure. Identification readers and computerized tracking systems are implemented as add-on modules that can be integrated without fundamentally redesigning the entire storage system, thereby achieving precise location tracking while limiting the increase in overall system complexity

Inventive Principle:
Principle #2Taking out (Extraction)
