Solution Overview

Problem

Existing tissue embedding machines often suffer from poor illumination, obstructive lighting, clogged drainage systems, and inefficient wax removal processes, which hinder the embedding and processing of tissue samples.

Innovation Solution

The histology tissue embedding apparatus incorporates dedicated LED lighting for improved illumination, a wax trimmer with a heated corrugated surface for efficient wax removal, and a removable waste receptacle system with drainage means to prevent clogging, along with a document holder for convenient note access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If traditional lighting is used in embedding machines, then illumination is provided, but the lighting gets in the way of the equipment operator and quality is poor

Engineering Contradiction:
Improvelighting qualityVSAvoidoperator obstruction
Core Design Contradiction:
Illumination intensityVSEase of operation

Solution Approach 1:

The patent replaces traditional mechanical/incandescent lighting systems with LED (Light Emitting Diode) technology. This substitution provides superior illumination quality while the compact LED design eliminates the obstruction problems associated with traditional lighting fixtures, allowing unobtrusive placement that does not interfere with operator movement or workspace accessibility.

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

2Productivity

If drainage tubes are used to drain paraffin wax, then wax can be drained from the reservoir, but the tubes get clogged-up

Engineering Contradiction:
Improvewax drainage efficiencyVSAvoiddrainage system reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent extracts and removes the problematic narrow drainage tubes from the system. Instead of using tube-based drainage that is prone to clogging, the design opens up the drainage pathway, allowing wax to drain directly into a waste receptacle without passing through constricted tube sections where clogs would form. This eliminates the reliability issue while maintaining drainage efficiency.

Inventive Principle:
Principle #2Taking out (Extraction)

3Stability of the object's composition

If a fixed trigger position is used, then the nozzle control is stable, but the space between trigger and outlet valve cannot be optimized

Engineering Contradiction:
Improvetrigger position stabilityVSAvoidworkspace space
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The patent introduces adjustability to the trigger mechanism, allowing the trigger position to be dynamically repositioned along a portion of its structure. This enables optimization of the space between the trigger and outlet valve for improved operator comfort and workspace ergonomics, while the adjustable design maintains operational stability when positioned and locked at the desired location.

Inventive Principle:
Principle #15Dynamics
