Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If full-field digital mammography is used for breast cancer detection, then detection accuracy is improved, but cost and availability worsen due to high acquisition cost and limited availability in developing countries
Solution Approach 1:
The patent uses ultrasound imaging as a copy or alternative modality to mammography, achieving comparable diagnostic value through a different physical principle (acoustic waves instead of X-rays). This allows deployment in resource-limited settings where mammography is unavailable
Solution Approach 2:
The patent replaces the X-ray based mammography system with an ultrasound-based system, substituting one physical mechanism (electromagnetic radiation) with another (acoustic waves), thereby achieving similar diagnostic goals without the cost and infrastructure requirements of mammography
2Measurement precision
If handheld ultrasound is used for breast imaging, then sensitivity for dense breast tissue is improved, but operator dependency and time consumption worsen
Solution Approach 1:
The system performs automated scanning and image processing without requiring expert operator intervention. The automated image reconstruction and analysis algorithms enable the system to serve itself, reducing dependency on skilled operators while maintaining high sensitivity for dense breast tissue
Solution Approach 2:
The patent replaces manual operator manipulation with automated mechanical scanning and computer-based image processing. The system uses automated probe positioning and algorithmic image reconstruction to eliminate operator dependency while preserving the sensitivity advantages of ultrasound for dense tissue
3Measurement precision
If handheld ultrasound is used for breast imaging, then sensitivity for dense breast tissue is improved, but time consumption worsens due to 20-30 minutes required for diagnosis
Solution Approach 1:
The system performs continuous automated scanning and real-time image processing, eliminating the intermittent manual operation of traditional ultrasound. The continuous automated acquisition and processing pipeline reduces total examination time while maintaining high sensitivity through comprehensive tissue coverage
Solution Approach 2:
The patent uses automated image processing algorithms that rapidly reconstruct and analyze ultrasound images, creating a streamlined version of the diagnostic process that maintains sensitivity while dramatically reducing the time required compared to manual interpretation of 20-30 minutes
4Extent of automation
If automated breast ultrasound systems are used, then operator independence is improved, but device size and cost worsen due to bulky size
Solution Approach 1:
The system divides the automated ultrasound functionality into separate modular components: a compact scanning probe, an automated positioning mechanism, and a separate processing unit. This segmentation allows the imaging device itself to remain small and portable while achieving operator independence through distributed automation functions
Solution Approach 2:
The patent replaces bulky mechanical automation systems with compact electronic and software-based solutions. Automated image processing and analysis algorithms perform complex functions without requiring large mechanical components, enabling operator independence in a portable device
