Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional rigid head coils are used, then structural stability is improved, but access to surgical site and patient comfort deteriorate
Solution Approach 1:
The head coil is divided into multiple segmented elements that can be independently positioned and adjusted. These segments are connected through flexible joints, allowing the coil to maintain structural integrity while adapting to different surgical access requirements and patient head shapes.
Solution Approach 2:
The head coil transitions from a static rigid structure to a dynamic adjustable structure. The coil elements can be repositioned and reconfigured during surgical procedures to optimize both structural stability and surgical access, allowing real-time adaptation to changing surgical needs.
2Stability of the object's composition
If conventional rigid head coils are used, then structural stability is improved, but patient comfort and claustrophobia reduction deteriorate
Solution Approach 1:
The coil structure is segmented into multiple adjustable elements that can be spaced apart, creating an open framework rather than an enclosed cage. This segmentation reduces the enclosed feeling that causes claustrophobia while maintaining the necessary structural stability through the connected elements.
Solution Approach 2:
The head coil incorporates flexible connections and thin structural elements between the coil segments, creating a more open and less confining structure. This flexibility allows the coil to adapt to patient head contours while reducing the enclosed birdcage effect that triggers claustrophobia.
3Ease of operation
If flat surface coils are used, then surgical access is improved, but signal-to-noise ratio deteriorates
Solution Approach 1:
The surface coil is shaped to conform to the curved surface of the patient's head rather than remaining flat. This curvature allows the coil to maintain close proximity to the cranial structures, optimizing the signal-to-noise ratio for MRI imaging while still providing adequate surgical access through its flexible, form-fitting design.
Solution Approach 2:
The surface coil is designed with flexible, adjustable elements that can be dynamically positioned to optimize both the distance from the head surface (for signal quality) and the access pathways for surgical instruments. The coil can be adjusted during procedures to balance imaging quality and surgical access requirements.
4Adaptability or versatility
If adjustable framework is introduced, then surgical access and adaptability are improved, but device complexity increases
Solution Approach 1:
The adjustable framework is segmented into standardized modular elements that can be independently positioned and configured. Each segment contains integrated adjustment mechanisms, allowing surgical access to be optimized without requiring complex overall system adjustments. The modular nature simplifies the adjustment process while maintaining versatility.
Solution Approach 2:
The adjustable framework uses universal connection interfaces and standardized adjustment mechanisms that serve multiple functions. The same structural elements provide both structural support and adjustment capabilities, reducing the need for separate complex mechanisms and simplifying the overall device design while maintaining adaptability.

AI summary
A wearable, open and adjustable MRI head coil system having an assembly of support members, panels, or portions defining one or more access openings. The support members, panels, or portions can support, house, or otherwise include radiofrequency receiver antennae or imaging coils such that the assembly is positionable or wearable by a patient for MRI scanning. The radiofrequency receiver antennae or imaging coils, and other devices can be simultaneously in contact with a patient's head, thereby enabling use during diagnostic, therapeutic, surgical or other interventional procedures.
