Solution Overview

Problem

Current microtomes require manual adjustment of cutting parameters for each specimen, leading to inefficiencies, increased labor costs, and higher error rates, especially when processing multiple specimens with different parameters.

Innovation Solution

A microtome equipped with a blade-holder and cassette-holder device that automatically acquires an identification code from the cassette, associating specific cutting parameters with the code, allowing for quick retrieval and adjustment of these parameters during subsequent sectioning procedures, reducing the need for manual input and minimizing operator errors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manual adjustment of cutting parameters is performed for each specimen, then the microtome can process different specimens with varying requirements, but the processing time increases and labor costs rise

Engineering Contradiction:
Improveability to process different specimensVSAvoidprocessing speed
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The microtome system automatically retrieves cutting parameters from a database using the cassette identification code, eliminating the need for manual operator input. The system serves itself by autonomously configuring optimal cutting parameters based on the specimen type identified through the code, thereby increasing productivity while maintaining adaptability across different specimen types

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Cutting parameters are pre-stored in a database associated with specific identification codes before the actual sectioning process. When a cassette is placed in the microtome, the system automatically retrieves the pre-configured parameters, eliminating the need for real-time manual adjustment and enabling faster processing while preserving specimen-specific optimization

Inventive Principle:
Principle #10Preliminary action

2Reliability

If manual adjustment of cutting parameters is performed for each specimen, then the operator can ensure correct parameters are used, but the error rate increases due to repeated manual input

Engineering Contradiction:
Improvecorrect parameter applicationVSAvoidoperator workload
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system automatically retrieves and applies the correct cutting parameters from the database using the identification code, eliminating manual operator input. This self-service mechanism ensures parameter accuracy while significantly reducing operator workload and the potential for human error in parameter selection and entry

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system uses the identification code on the cassette as a feedback mechanism to automatically retrieve the corresponding cutting parameters from the database. This closed-loop approach ensures that the correct parameters are consistently applied for each specimen type without relying on manual operator judgment or input, thereby improving reliability while easing operational burden

Inventive Principle:
Principle #23Feedback

3Manufacturing precision

If cutting parameters are manually adjusted for each specimen type, then the sectioning quality can be optimized, but the time required for parameter setup increases

Engineering Contradiction:
Improvesectioning qualityVSAvoidparameter setup time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

Optimal cutting parameters for different specimen types are pre-determined and stored in the database before actual use. When a cassette is placed in the microtome, the system automatically retrieves these pre-optimized parameters using the identification code, eliminating the time-consuming manual setup process while preserving sectioning quality through proven parameter configurations

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The microtome system autonomously retrieves the optimized cutting parameters from the database based on the identification code, eliminating the need for manual parameter adjustment. This self-service approach maintains high sectioning quality through pre-optimized settings while drastically reducing the time required for parameter setup between different specimen types

Inventive Principle:
Principle #25Self-service
