Solution Overview

Problem

Current methods for analyzing biological samples are limited in their ability to provide comprehensive and accurate optical and image analysis, particularly in providing both epi-illumination and trans-illumination simultaneously, which is essential for detailed sample examination and measurement.

Innovation Solution

The development of a sample holder with an optically transmissive portion and a reflective surface that enables both epi-illumination and trans-illumination, using partial or total internal reflection to illuminate samples from multiple directions, combined with a detector system for precise measurement and analysis.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If a sample holder uses only trans-illumination, then the sample can be illuminated from below, but the sample cannot receive epi-illumination from above simultaneously

Engineering Contradiction:
Improveillumination capabilityVSAvoidillumination mode flexibility
Core Design Contradiction:
Illumination intensityVSAdaptability or versatility

Solution Approach 1:

The sample holder is designed to perform multiple illumination functions simultaneously. The holder includes both a light source positioned below the sample for trans-illumination and a reflective surface positioned above the sample to reflect light onto the sample for epi-illumination, enabling the single device to provide both illumination modes at the same time

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

Solution Approach 2:

The invention adds a vertical dimension to light delivery by positioning light sources and reflective surfaces on both the top and bottom sides of the sample holder. This multi-dimensional light delivery approach allows light to reach the sample from multiple directions (from below through the holder and from above via reflection), transforming a single-direction illumination system into a multi-directional one

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Measurement precision

If a sample holder provides illumination from multiple directions, then the optical examination capability is enhanced, but the device complexity increases

Engineering Contradiction:
Improveoptical examination accuracyVSAvoidsample holder structure
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The sample holder merges multiple illumination functions into a single integrated structure. The holder combines the light source, the reflective surface, and the sample positioning elements into one unified device, eliminating the need for separate illumination systems and reducing overall system complexity while maintaining multi-directional illumination capability

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The reflective surface is positioned and oriented within the sample holder such that it automatically reflects light onto the sample from above without requiring additional active components or complex control mechanisms. The geometry of the reflective surface itself provides the necessary light redirection, making the system self-regulating and reducing operational complexity

Inventive Principle:
Principle #25Self-service
