Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If optical methods are used to scan deeper tissue depths, then imaging capability is improved, but light scattering increases and detection reliability deteriorates
Solution Approach 1:
The bra is divided into multiple cups, each containing an array of optical modules (light emitters and receivers) arranged in specific patterns. This segmentation allows targeted optical scanning of different breast regions at optimal depths, improving detection reliability by focusing light paths on specific tissue layers rather than attempting to scan the entire breast volume uniformly.
Solution Approach 2:
Different regions of the bra cups have different densities of optical modules and varying light emitter-receiver pair configurations optimized for local tissue depth requirements. The optical module arrays are positioned and oriented to match the anatomical structure of the breast, with closer spacing for superficial layers and wider spacing for deeper tissues, thereby maintaining detection reliability across varying depths.
2Measurement precision
If more optical modules are added to improve detection capability, then measurement precision is improved, but device complexity increases
Solution Approach 1:
Multiple optical modules (light emitters and receivers) are merged into integrated arrays within each bra cup, with the modules electrically and mechanically coupled to form unified scanning units. This merging reduces the number of discrete components and simplifies the overall bra structure while maintaining high measurement precision through the coordinated operation of multiple modules.
Solution Approach 2:
The optical modules are designed to perform multiple functions: light transmission, light reception, and signal processing within the same modular units. The same bra cup structure houses both emission and detection capabilities, allowing the device to achieve precise measurement of tissue optical properties without requiring separate complex systems for each function.

Function Achieved in This Case
Enhances the ability to detect, locate, and characterize abnormal breast tissue by improving light transmission and scanning capabilities, potentially leading to more effective early detection and imaging of breast cancer.
Implementation Method 1
Light from the light emitters is received by the light receivers after it has been transmitted through breast tissue
Implementation Method 2
face challenges in scanning deeper tissue depths due to increased light scattering
Implementation Method 3
a movable light guide (such as a movable micromirror) which reflects a beam of light from a light emitter toward a breast
Implementation Method 4
expandable chambers or piezoelectric bands which gently compress the breast to improve optical scanning

AI summary
A smart bra uses optical modules with light emitters and light receivers to screen for breast cancer. Light is transmitted through breast tissue and analyzed to detect, locate, image, and/or characterize abnormal breast tissue. Each optical module can have two light emitters which emit light at different wavelengths and a light receiver. An optical module can also include a movable light guide which reflects and scans beams of light from a light emitter through breast tissue at different angles.
