Solution Overview

Problem

Current sensorized garments, especially those used in sports, struggle to provide accurate and reliable data on impact dynamics to medical staff after an accident, as information from affected individuals or witnesses can be unreliable, and reconstruction based on the accident scene is often inaccurate.

Innovation Solution

A sensorized garment with an under helmet hood incorporating textile pressure and deformation sensors, along with optional acceleration sensors, that transmit data to an external processing unit via a mobile network, generating a virtual map to represent trauma areas and provide accurate impact dynamics information to medical staff.

1Reliability

If medical staff rely on information from affected individuals or witnesses to reconstruct accident dynamics, then the information can be obtained quickly, but the reliability and accuracy of the impact data deteriorates due to trauma effects and theoretical deduction

Engineering Contradiction:
Improvereliability of impact dataVSAvoidcomplexity of sensorized garment
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent incorporates sensors and data processing capabilities into the garment before the accident occurs. The system is pre-configured with accelerometers, pressure sensors, and other detection devices that automatically activate upon impact, eliminating the need for post-accident data collection from traumatized individuals.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The sensorized garment acts as an intermediary device between the impact event and the medical staff. Instead of relying on human witnesses or theoretical reconstruction, the garment directly measures and transmits objective impact data including acceleration forces, pressure points, and deformation patterns.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If multiple types of sensors (pressure, deformation, acceleration) are incorporated into the under helmet hood, then the measurement precision and completeness of trauma data improves, but the device complexity and manufacturing difficulty increases

Engineering Contradiction:

Solution Approach 1:

The under helmet hood is designed as a multi-functional base structure that integrates multiple sensor types (accelerometers, pressure sensors, deformation sensors) into a single universal platform. This allows one garment component to perform multiple detection functions, reducing the need for separate devices and simplifying the overall system.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent utilizes sensors that detect different physical parameters (acceleration, pressure, deformation) and converts them into standardized electrical signals that can be processed uniformly by the control unit. This parameter conversion approach allows diverse sensor types to work together seamlessly within a single system architecture.
