Solution Overview

Problem

Existing methods for alleviating friction during childbirth, particularly in obstructed labour, are inadequate as they fail to maintain consistent lubrication, leading to increased friction and potential complications.

Innovation Solution

A hydrogel membrane or device is used to cover or line the baby or birth canal during childbirth, providing a self-lubricating surface that reduces friction by maintaining a fluid film, thereby preventing direct skin-mucosal contact and minimizing the risk of obstructed labour.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If water-based gel lubricants are used during childbirth, then friction is reduced initially, but friction increases significantly after a short duration due to water loss from evaporation and absorption

Engineering Contradiction:
ImprovefrictionVSAvoidduration of lubrication
Core Design Contradiction:
Object-affected harmful factorsVSDuration of action of moving object

Solution Approach 1:

The patent changes the physical-chemical parameters of the lubricant by using hydrogel materials with specific water content (60-90% by weight) and controlled gel structure. This transforms the lubricant from a simple water-based gel that evaporates to a hydrogel system that maintains its water content through gel network structure, thereby extending the duration of effective lubrication throughout the entire childbirth process

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent employs composite hydrogel materials combining water (60-90% by weight) with gel-forming polymers. This composite structure allows the lubricant to maintain both the lubricating properties of water and the structural integrity of the gel network, preventing water loss through evaporation and absorption while extending lubrication duration

Inventive Principle:
Principle #40Composite materials

2Object-affected harmful factors

If liquid lubricant is used during childbirth, then friction is reduced, but the lubricant is pushed away from the sliding surface by uterine contractions and maternal pushing, exposing the surface to boundary lubrication

Engineering Contradiction:
ImprovefrictionVSAvoidconsistency of lubrication
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent applies hydrogel thin films that conform to the sliding surfaces during childbirth. These flexible hydrogel films remain in contact with the birth canal walls despite the dynamic forces of uterine contractions and maternal pushing, maintaining continuous lubrication and preventing exposure to boundary lubrication conditions

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The hydrogel acts as an intermediary material between the baby's skin and the birth canal mucosa. This intermediary layer maintains stable contact and provides consistent lubrication throughout the delivery process, mediating the interaction between the moving foetal head and the stationary birth canal walls

Inventive Principle:
Principle #24Intermediary (Mediator)

3Object-affected harmful factors

If natural lubricant is used during childbirth, then some lubrication is provided, but it may not fully cover the sliding surface throughout the delivery process

Engineering Contradiction:
ImprovefrictionVSAvoidcovered surface area
Core Design Contradiction:
Object-affected harmful factorsVSArea of stationary object

Solution Approach 1:

The patent employs flexible hydrogel films that can be applied to cover extensive surface areas of the birth canal and/or baby. These thin films conform to the anatomical structures and provide complete surface coverage, ensuring that the entire sliding surface remains lubricated throughout the delivery process

Inventive Principle:
Principle #30Flexible shells and thin films
