Solution Overview

Problem

Current head coolers are not easily adaptable to the varying size and shape of patients' heads and necks, leading to reduced cooling efficiency and failure to effectively cool the scalp and eyebrows, resulting in hair loss during cytostatic treatments.

Innovation Solution

A head cooler with a thermal exchange cap that is adjustable and adaptable, featuring partitioned sections with flow passages and an outer insulating cover, along with an inner flexible bag for improved contact and fluid distribution, and an optional eyebrow cooler for comprehensive cooling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed-size head cooler is used, then the device structure is simple, but the cooling efficiency is reduced due to gaps between the heat exchange surface and the head

Engineering Contradiction:
Improveadaptability to head size and shapeVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The head cooler is divided into multiple adjustable sections that can be independently positioned to conform to different head shapes and sizes. Each section contains flow passages and can be adjusted to eliminate gaps between the heat exchange surface and the scalp, improving cooling efficiency without requiring a completely new device design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The head cooler incorporates adjustable components that allow dynamic adaptation to various head geometries. The sections can be moved and repositioned to match the patient's head shape, transforming a static device into a dynamically adaptable one that maintains optimal contact across different anatomical variations.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the head cooler is made too large to accommodate all head sizes, then it can fit more patients, but gaps are formed between the heat exchange surface and the head, reducing cooling efficiency

Engineering Contradiction:
Improveuniversality across different patientsVSAvoidcooling efficiency
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

By segmenting the head cooler into multiple adjustable sections, the device achieves universality across different patient sizes while maintaining reliable cooling efficiency. Each section can be independently adjusted to eliminate gaps, ensuring that the heat exchange surface maintains optimal contact with the scalp regardless of the patient's head dimensions.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different sections of the head cooler can be adjusted to provide locally optimized contact with the scalp. Each section's heat exchange surface can be positioned to match the local head geometry, ensuring uniform cooling efficiency across the entire head surface while accommodating variations in head size and shape.

Inventive Principle:
Principle #3Local quality

3Ease of operation

If conventional head coolers are used, then the basic cooling function is provided, but the eyebrows and hairline regions are not effectively cooled, resulting in hair loss in these areas

Engineering Contradiction:
Improveease of useVSAvoidcomprehensive cooling coverage
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The head cooler is segmented to include specific sections that extend to cover the eyebrows and hairline regions. These additional sections ensure comprehensive cooling coverage of all hairy areas on the head, preventing hair loss in previously neglected regions while maintaining ease of use through the standardized adjustable design.

Inventive Principle:
Principle #1Segmentation

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

AI summary

A head cooler (10) comprises a thermal exchange cap (11) and an outer insulating cover (12) to be arranged on a patient's head. The cap (11) has a channel system (31, 32) for a cooling fluid forming an inside heat exchange surface to be applied on said head for cooling the head. The thermal exchange cap (11, 60) is adjustable and/or adaptable to compensate for a discrepancy in shape and size between the inside surface of the head cooler (10) and the head. The head cooler (10) may further comprise an eyebrow cooler (140) for cooling the area of the eyebrows. The head cooler (140) is used in medicine. A method for preventing hair loss of a patient is provided by arranging the head cooler (10) on the head of said patient.
