Solution Overview

Problem

Current pharmacological therapeutics for insomnia primarily focus on helping patients fall asleep but often fail to maintain sleep throughout the night, leading to incomplete sleep cycles and associated side effects like addiction and next-morning impairment.

Innovation Solution

A controlled-release formulation that administers one or more sleep-affecting compounds in specific doses and at specific times, utilizing multiple stages of release to extend sleep duration while minimizing side effects, employing a combination of polymeric compositions and coatings for precise drug delivery.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If conventional sleeping pills are used to help patients fall asleep, then the ability to fall asleep is improved, but the ability to remain asleep for sufficient time deteriorates

Engineering Contradiction:
Improvespeed to fall asleepVSAvoidduration of sleep maintenance
Core Design Contradiction:
SpeedVSDuration of action of moving object

Solution Approach 1:

The patent divides the sleep medication into multiple dosage stages released at different times during the night. The formulation includes an immediate-release component for rapid sleep onset and a controlled-release component for sustained sleep maintenance, thereby resolving the contradiction between fast sleep induction and prolonged sleep duration.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent employs periodic drug release patterns with distinct phases: an initial burst release for rapid sleep onset, followed by sustained release phases at predetermined intervals to maintain sleep throughout the night. This periodic action pattern addresses both the need for quick sleep induction and continuous sleep maintenance.

Inventive Principle:
Principle #19Periodic action

2Duration of action of moving object

If higher doses of sleeping pills are used to extend sleep duration, then the duration of sleep is improved, but the risk of addiction and side effects worsens

Engineering Contradiction:
Improveduration of sleepVSAvoidaddiction and side effects
Core Design Contradiction:
Duration of action of moving objectVSObject-affected harmful factors

Solution Approach 1:

The patent segments the total drug dose into multiple smaller administrations throughout the night via controlled-release mechanisms. This segmentation allows extended sleep duration while avoiding the need for high single doses, thereby reducing addiction risk and side effects such as next-morning impairment.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent provides continuous low-dose drug delivery throughout the sleep period rather than a single high dose. This continuous action maintains therapeutic effect for extended duration while keeping individual dose levels low enough to minimize harmful effects and addiction potential.

Inventive Principle:
Principle #20Continuity of useful action

3Duration of action of moving object

If multiple drugs are administered to maintain sleep throughout the night, then the duration of sleep is improved, but the complexity of the treatment regimen worsens

Engineering Contradiction:
Improveduration of sleepVSAvoidcomplexity of medication regimen
Core Design Contradiction:
Duration of action of moving objectVSDevice complexity

Solution Approach 1:

The patent combines multiple drugs with different release profiles into a single unified formulation. This single combined product delivers multiple medications at appropriate times and doses, simplifying the treatment regimen while achieving extended sleep maintenance that would otherwise require multiple separate administrations.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent creates a multi-functional formulation that performs multiple functions: rapid sleep induction, sustained sleep maintenance, and minimization of side effects. This universal formulation replaces what would traditionally require multiple separate medications and administrations, reducing regimen complexity.

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