Solution Overview

Problem

Existing inspection devices face challenges in preventing or rapidly removing dew condensation on sample containers without causing a heat shock to the samples, particularly during time-lapse observations of rapidly growing bacteria, as conventional heating methods risk overheating the samples.

Innovation Solution

An inspection device with an isothermal part, detection part, and transportation part, featuring a mechanism that lifts the lid of the sample container to create a gap for dew condensation removal, using heaters to raise the lid temperature above the ambient temperature without affecting the sample, and includes a dew condensation prevention mechanism in the transportation mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a camera is disposed inside a hollow needle for intraluminal imaging, then imaging capability is provided, but the needle structure becomes complex and manufacturing difficulty increases

Engineering Contradiction:
Improveimaging capabilityVSAvoidneedle structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The inspection device is divided into separate functional modules: an inspection unit with imaging device and light source, and a puncture needle unit. These modules can be assembled and disassembled independently, reducing manufacturing complexity while maintaining imaging capability within the needle assembly.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The inspection device is designed to perform multiple functions: imaging, illumination, and potential therapeutic interventions. The modular design allows the same base needle structure to accommodate different inspection devices for various imaging modalities (optical, fluorescent, etc.).

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

2Reliability

If insulation layers are added to protect wires from corrosion by saline solution, then wire reliability is improved, but the device structure becomes more complex

Engineering Contradiction:
Improvewire corrosion resistanceVSAvoidinsulation structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Thin flexible insulation layers are applied to wire surfaces to provide corrosion protection. These thin films maintain wire flexibility and electrical conductivity while protecting against saline solution degradation, avoiding the need for bulky protective structures.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The wire construction uses composite material structures combining conductive core materials with protective insulation layers. This composite approach provides both electrical functionality and corrosion resistance in a integrated structure rather than separate components.

Inventive Principle:
Principle #40Composite materials
