Solution Overview

Problem

Existing systems for monitoring physiological parameters in field settings face challenges in securely attaching monitoring devices to garments without interference with user activities, while ensuring easy connection and disconnection, manufacturability, and usability.

Innovation Solution

A system comprising a housing with sensor pads that removably attaches to a garment interface, using leaf springs or rivets to establish electrical contact with integrated sensors, and a snap-fit mechanism to secure the device in place, allowing for secure attachment and easy removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the monitoring device is removably attached to the garment, then ease of connection and disconnection is improved, but security of attachment may deteriorate

Engineering Contradiction:
Improveease of connection and disconnectionVSAvoidsecurity of attachment
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The monitoring device is divided into separate components: a housing that can be removably attached to the garment and sensor pads that remain integrated with the garment. This segmentation allows the housing to be easily connected and disconnected while the sensor pads maintain secure attachment to the garment through stitching or integration into the fabric.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The attachment mechanism incorporates dynamic elements such as spring-loaded contacts or snap-fit connections that automatically engage and disengage. These dynamic features provide secure attachment during normal use while allowing easy removal when needed, resolving the contradiction between security and ease of operation.

Inventive Principle:
Principle #15Dynamics

2Reliability

If the monitoring device is securely attached to prevent dislodgement, then reliability is improved, but interference with user activities may worsen

Engineering Contradiction:
Improvesecurity of attachmentVSAvoidinterference with user activities
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The monitoring device distributes its attachment points locally across the garment rather than using a single large secure attachment mechanism. Multiple small sensor pads are distributed at specific locations on the garment, providing secure attachment without creating a bulky or intrusive single-point attachment that would interfere with user activities.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent replaces traditional mechanical fastening systems (zippers, buttons, Velcro) with integrated sensor pads that are stitched or bonded directly into the garment fabric. This substitution eliminates bulky mechanical components that would interfere with user activities while maintaining secure attachment through the distributed sensor array.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of manufacture

If sensor pads are integrated into the garment, then ease of manufacture is improved, but device complexity may worsen

Engineering Contradiction:
Improveintegration of sensors into garmentVSAvoidcomplexity of attachment system
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The sensor pads are merged with the garment fabric during the manufacturing process, either by stitching, bonding, or weaving the sensors directly into the textile. This merging simplifies the overall system by eliminating separate attachment components and reduces device complexity by integrating the sensing function directly into the garment structure.

Inventive Principle:
Principle #5Merging (Combining)
