Solution Overview

Problem

Existing methods for forming tissue pieces for tissue arrays face challenges in achieving stable and accurate winding around a core rod, particularly due to the fusion of embedding media like paraffin with the mounting block, leading to manual and non-automated processes that can damage tissues.

Innovation Solution

A method involving a peeling means with a second embedding medium of lower melting point, applied between the sheet-like tissue piece and the mounting block, allows for stable and accurate winding by preventing fusion and enabling automated processing, along with the use of a mounting block with a heater and a detachable plate for tissue handling and identification.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the sheet-like tissue piece is heated on the mounting block to improve flexibility for winding, then the embedding medium softens and flexibility is improved, but the tissue piece is welded to the mounting block by fusion of the embedding medium, preventing automated winding

Engineering Contradiction:
Improveflexibility of tissue pieceVSAvoidautomated winding capability
Core Design Contradiction:
Ease of operationVSExtent of automation

Solution Approach 1:

A peeling means is introduced as an intermediary layer between the tissue piece and the mounting block. This peeling means prevents direct adhesion while allowing the tissue piece to be easily peeled off after winding, thus enabling automated processing without manual intervention to separate the tissue from the mounting block

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The melting point of the embedding medium is changed by using a second embedding medium with a lower melting point for the peeling means. This parameter change allows the peeling means to be peeled off easily when heated, preventing welding of the tissue piece to the mounting block while maintaining the necessary flexibility for winding

Inventive Principle:
Principle #35Parameter changes

2Reliability

If manual winding is used to prevent tissue destruction, then tissue integrity is maintained, but processing efficiency is reduced and automation is lost

Engineering Contradiction:
Improvetissue integrityVSAvoidprocessing efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The peeling means acts as a mediator that enables the tissue piece to be handled without direct contact with the mounting block during winding. This prevents tissue destruction while allowing automated winding mechanisms to be used, thereby maintaining both tissue integrity and processing efficiency

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

By changing the physical properties of the peeling means (using a material with lower melting point), the tissue piece can be heated to the appropriate temperature for winding without risk of welding to the mounting block. This enables automated winding while preserving tissue integrity

Inventive Principle:
Principle #35Parameter changes
