Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional medical imaging techniques for musculoskeletal disorders are limited by the use of ionizing radiation in X-ray and CT scans, high costs and claustrophobia issues with MRI, and the inability to assess dynamic joint movement and function.
Innovation Solution
A detection device with a deformable carrier and multiple detection units that emit and receive high-frequency radiation, allowing for dynamic imaging and movement assessment by changing the relative position of the units, enabling real-time three-dimensional visualization of joint movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If X-ray or CT scan is used for imaging, then bone pathology can be assessed, but ionizing radiation damage occurs
Solution Approach 1:
The patent replaces ionizing radiation-based imaging (X-ray/CT) with a mechanical wave-based detection system using acoustic waves and piezoelectric sensors to image bone pathology, thereby eliminating radiation exposure while maintaining diagnostic capability
Solution Approach 2:
The patent introduces acoustic waves as an intermediary medium to transmit information about bone pathology from the detection area to the sensors, replacing direct ionizing radiation interaction with a harmless mechanical wave propagation process
2Measurement precision
If MRI is used for soft tissue imaging, then excellent visualization is achieved, but examination time increases and cost increases
Solution Approach 1:
The patent extracts and focuses specifically on bone pathology detection using acoustic wave reflection principles, separating this function from the complex, time-consuming full-body MRI process, thereby achieving rapid targeted imaging
Solution Approach 2:
The patent employs a portable, relatively simple acoustic detection device that can be quickly deployed and removed, contrasting with the expensive, fixed MRI infrastructure, enabling faster and more accessible imaging
3Measurement precision
If conventional imaging is used, then static images are obtained, but dynamic movement assessment is not possible
Solution Approach 1:
The patent transforms the detection system from a static imaging modality to a dynamic one by enabling real-time acquisition of acoustic wave data during joint movement, allowing assessment of functional mechanics rather than just anatomical structure
Solution Approach 2:
The patent implements continuous acoustic wave emission and detection during joint movement, maintaining uninterrupted data flow to capture dynamic functional information, rather than taking discrete static snapshots
4Measurement precision
If MRI system is used, then detailed imaging is achieved, but patient claustrophobia is caused
Solution Approach 1:
The patent uses a flexible, wearable detection device with acoustic sensors that can conform to the patient's body, replacing the confining MRI bore with an open, comfortable configuration that maintains imaging capability
5Adaptability or versatility
If X-ray machine is made mobile, then portability is improved, but infrastructure cost increases
Solution Approach 1:
The patent replaces the complex, infrastructure-dependent X-ray generation system with a portable acoustic wave generation and detection system using piezoelectric elements, eliminating the need for heavy shielding and power infrastructure

AI summary
In various embodiments, a detection device (100) comprises: a deformable carrier (102) that can at least partially surround a predetermined area (110); detection units (104) attached to the carrier (102) that emit first RF radiation (HF) in the direction of a detection area (108) and receive second RF radiation (HF) from the detection area (108), wherein the received second RF radiation (HF) represents one or more properties of the detection area (108) and is based on the emitted first RF radiation (HF). The relative position of the detection units can be changed due to deformation of the carrier (102). An evaluation device (106) can determine the relative positions of the detection units based on the received second RF radiation. An output is provided based on the determined relative position.
