Solution Overview

Problem

Current capsule endoscopes lack Narrow Band Imaging (NBI) capabilities, which are essential for highlighting mucosal epithelium and submucosal vessels, thereby limiting their ability to detect early cancer and other mucosal microvascular lesions.

Innovation Solution

A capsule endoscope imaging device equipped with first lamp bodies for white light emission, second lamp bodies emitting light with a central wavelength of 510 nm-540 nm, and third lamp bodies emitting light with a central wavelength of 400 nm-420 nm, along with control circuits to adjust exposure time or voltage, enabling switchable white light and narrow-band light illumination for NBI observation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If capsule endoscope uses only white light imaging (WLI), then patient comfort is improved, but the ability to highlight mucosal epithelium and submucosal vessels deteriorates

Engineering Contradiction:
Improvepatient comfortVSAvoiddetection accuracy of mucosal structures
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The capsule endoscope integrates multiple imaging modes (WLI and NBI) into a single device, enabling it to perform both general screening and detailed mucosal observation functions. The imaging device includes first lamp bodies for WLI, second lamp bodies for green light (510-540nm), and third lamp bodies for blue light (400-420nm), allowing the capsule to switch between different imaging modes based on diagnostic needs.

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

2Measurement precision

If capsule endoscope adds NBI imaging capabilities, then detection accuracy of early cancer is improved, but device complexity increases

Engineering Contradiction:
Improvedetection accuracy of early cancerVSAvoidimaging system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The imaging device is divided into separate functional modules: first lamp bodies for white light, second lamp bodies for green narrow-band light, and third lamp bodies for blue narrow-band light, each with dedicated control circuits. This segmentation allows independent optimization and control of each imaging mode while maintaining overall system manageability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent combines WLI and NBI imaging systems into a single integrated capsule endoscope device. The mounting board holds all lamp bodies and control circuits in a compact arrangement, merging the functions of multiple imaging systems into one unified platform that can switch between modes.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If capsule endoscope uses multiple lamp bodies with different wavelengths, then imaging versatility is improved, but energy consumption increases

Engineering Contradiction:
Improveimaging mode versatilityVSAvoidpower consumption of capsule
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The capsule endoscope employs periodic switching between different imaging modes (WLI and NBI) rather than continuous operation of all lamp bodies. The control circuits activate specific lamp bodies only when their corresponding imaging mode is required, reducing overall energy consumption while maintaining imaging versatility.

Inventive Principle:
Principle #19Periodic action
