Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high volume of radiographic images generated by security inspection systems, particularly in customs inspection stations, puts significant pressure on communication lines due to the need for centralized review, leading to time-consuming data transmission and inefficient processing.
Innovation Solution
A security inspection system and method that involves on-site image processing computers storing and processing radiographic images in real time, with remote image processing computers accessing and synchronizing only the necessary data for display, using a task assignment server to manage connections and optimize bandwidth, and employing image compression and filtering to reduce data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If entire radiographic images are transmitted to centralized review centers, then complete image data is available for review, but communication line pressure increases significantly
Solution Approach 1:
The patent extracts only the necessary image data (displayed pixels and their surrounding regions) from the complete radiographic image, transmitting only this extracted portion to the centralized review center. This eliminates the need to transmit the entire high-resolution image while still providing sufficient data for effective image review, thus reducing communication bandwidth consumption while maintaining information availability.
Solution Approach 2:
The patent segments the complete radiographic image into multiple regions, identifying and transmitting only the relevant segments that contain displayed pixels and their surrounding areas. This segmentation approach divides the large image data into smaller, manageable portions that can be transmitted efficiently over communication lines without sacrificing the essential review information.
2Measurement precision
If high-resolution radiographic images are processed and transmitted, then image quality is maintained, but data transmission time increases
Solution Approach 1:
The patent extracts only the essential visual information needed for review (displayed pixels and their surrounding regions) rather than transmitting the complete high-resolution image. This extraction maintains sufficient image quality for effective review while dramatically reducing the data volume that needs to be transmitted, thereby reducing transmission time without sacrificing measurement precision for the review purpose.
Solution Approach 2:
The patent changes the parameter of image data resolution by transmitting lower-resolution extracted regions instead of the original high-resolution complete image. The extracted regions containing displayed pixels are transmitted at sufficient resolution for review, while the overall data volume is reduced by transmitting only these specific regions rather than the entire high-resolution image, thus balancing image quality with transmission speed.
3Reliability
If centralized review requires all image data, then review accuracy is ensured, but communication infrastructure strain increases
Solution Approach 1:
The patent extracts only the necessary image portions (displayed pixels and surrounding regions) that are sufficient for accurate review, eliminating the need to transmit and process complete high-resolution images at the centralized review center. This extraction approach ensures review accuracy is maintained while significantly reducing the complexity and strain on communication infrastructure.
Solution Approach 2:
The patent segments the image transmission task into transmitting only relevant regions rather than complete images. This segmentation reduces the total data volume requiring communication infrastructure support, thereby reducing infrastructure complexity and strain while maintaining the reliability needed for accurate review through transmission of sufficient image portions.
4Loss of information
If complete images are stored and transmitted, then no data loss occurs, but processing load on communication lines increases
Solution Approach 1:
The patent extracts only the essential image data (displayed pixels and their surrounding regions) from complete images for transmission and processing. This extraction maintains data integrity for the reviewed portions while significantly reducing the processing load on communication lines by eliminating the need to handle, transmit, and process complete high-resolution images.
Solution Approach 2:
The patent segments the image data into transmitted portions (displayed regions) and non-transmitted portions (other regions). This segmentation improves processing efficiency by reducing the volume of data that needs to be processed through communication lines, while maintaining data integrity for the segments that are transmitted and reviewed.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach reduces the pressure on communication lines by minimizing the amount of data transmitted, allowing for real-time remote review of images without the need to send entire images, enhancing processing efficiency and improving user experience even in environments with insufficient bandwidth.
