Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a one-size-fits-all silicon cap is used, then the device complexity is reduced, but the fit reliability deteriorates
Solution Approach 1:
The scalp cooling system is divided into multiple sections (front, rear, left, right portions) that can be independently adjusted to fit different scalp shapes and sizes. Each section contains cooling channels that can be customized to match the patient's anatomy, thereby improving fit reliability without significantly increasing overall device complexity.
Solution Approach 2:
The system incorporates adjustable mechanisms that allow dynamic adaptation to individual patient scalps. The cap can be customized in terms of shape, size, and cooling channel configuration based on 3D scanning data, enabling the device to dynamically adapt to different patients rather than using a static one-size-fits-all approach.
2Ease of manufacture
If a standardized cooling cap is used, then the ease of manufacture is improved, but the temperature control precision deteriorates
Solution Approach 1:
The system uses 3D scanning to capture patient-specific scalp parameters and generates customized cooling cap designs based on this data. The cooling channel configuration, cap shape, and size are all parameterized and adjusted according to individual patient measurements, enabling precise temperature control while maintaining manufacturing feasibility through automated design generation.
3Temperature
If cooling channels are integrated into the scalp covering, then the temperature regulation effectiveness is improved, but the device complexity increases
Solution Approach 1:
The cooling channels are integrated directly into the scalp covering structure itself, merging the cooling function with the protective and conforming functions of the cap. This combination eliminates the need for separate cooling devices and simplifies the overall system, while still achieving effective temperature regulation through direct contact between the cooling channels and the scalp.

AI summary
A scalp cooling apparatus, method, and system that may include an inner scalp cap, an intermediate scalp covering, and an outer scalp cap. The inner scalp cap may be fluidly coupled to a cooling device, that would allow a cooling fluid to traverse the fluid chambers within a set of sections of the inner scalp cap. The inner scalp covering can be constructed of a thermally conductive material. The intermediate scalp covering can be constructed of a thermally neutral material. The outer scalp covering can be constructed of a thermally resistant material. The outer scalp covering may have a first securing mechanism, and a second securing mechanism, that allow the outer scalp covering to be dynamically adjusted and secured against a patient's scalp via the first securing mechanism and the second securing mechanism. The inner scalp cap may be created from a scan of a patient's head, that can then be utilized as an interpolated parametric model may be utilized to generate an output file.
