Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Capsule endoscopes face discontinuity in imaging during high-speed movement due to non-overlapping imaging ranges and varying speeds, leading to incomplete data capture and potential image gaps.
Innovation Solution
A capsule endoscope system with dual imaging modules and a reception apparatus that dynamically adjust imaging intervals based on detected speed, instructing one module to image continuously and the other to perform additional imaging at shorter intervals when the capsule endoscope moves at high speeds, ensuring continuous data capture.

Engineering Contradiction Analysis
1Productivity
If the capsule endoscope moves at high speed, then the diagnostic efficiency is improved, but image discontinuity occurs due to non-overlapping imaging ranges
Solution Approach 1:
The imaging function is divided into multiple independent imaging modules, each capturing a specific field of view. When the capsule moves at high speed, different modules capture images from different positions, and the system integrates these segmented images to maintain continuous imaging coverage without gaps.
Solution Approach 2:
Multiple imaging modules are combined to work simultaneously, with their captured images merged by the image processing unit. This merging process creates a comprehensive and continuous image sequence that bridges the gaps between individual module captures during high-speed movement.
2Area of stationary object
If multiple imaging modules are used to cover broader ranges, then the imaging coverage is improved, but the device complexity increases
Solution Approach 1:
Multiple imaging modules are designed with the same basic structure and control mechanisms, allowing them to perform identical functions. This universality simplifies the overall system design compared to using modules with different specialized functions, as the same control algorithms and processing pipelines can be applied to all modules.
Solution Approach 2:
The imaging modules are replicated copies of the same basic imaging unit, each with identical sensors, lenses, and processing capabilities. This copying approach reduces design complexity by eliminating the need to develop and manage diverse component types, while still achieving broader coverage through parallel deployment of identical units.
3Quantity of substance
If the imaging time interval is reduced to capture high-speed movement, then the data coverage is improved, but the energy consumption increases
Solution Approach 1:
The imaging modules operate in a periodic manner, with the control unit coordinating the activation and deactivation of different modules based on the capsule's movement state. During high-speed movement, modules are activated at optimized intervals to maintain data coverage while minimizing continuous operation time, thereby reducing overall energy consumption compared to continuous imaging.
Solution Approach 2:
The imaging system dynamically adjusts its operation mode based on real-time detection of the capsule's movement speed. When moving at high speed, the system activates multiple modules with reduced time intervals to maintain coverage. When movement slows down, the system reduces the number of active modules and increases time intervals, thereby adapting energy consumption to actual operational needs.
