Bilayer Sleep Caplet with Segmented Release Layers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sleep aids often lead to negative side effects such as dependence, impaired cognitive function, and disruption of REM sleep, while failing to effectively address sleep quality and duration issues.
Innovation Solution
A customized bilayer caplet with an immediate release layer containing L-Theanine, Skullcap Herb, Rhodiola, and Chamomile, and a time release melatonin layer, designed to promote relaxation, induce sleep, and maintain sleep through a three-phase approach, avoiding the negative effects of traditional sleep aids.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If traditional sleep aids (benzodiazepines, Z-drugs) are used to induce sleep, then sleep onset is improved, but dependence and side effects occur
Solution Approach 1:
The patent divides the sleep aid into two distinct layers: an immediate-release layer containing herbal ingredients (L-Theanine, Skullcap, Rhodiola, Chamomile) for rapid relaxation effect, and a time-release layer containing melatonin for sustained sleep maintenance. This segmentation allows different mechanisms to work at different times, achieving fast sleep onset without the dependence risks of traditional hypnotics.
Solution Approach 2:
The invention combines multiple natural ingredients with complementary mechanisms of action: GABAergic herbs (L-Theanine, Skullcap, Chamomile) for immediate relaxation, adaptogenic Rhodiola for stress reduction, and melatonin for circadian rhythm regulation. This composite approach creates a synergistic effect that addresses sleep onset and maintenance while avoiding dependence.
2Duration of action of moving object
If traditional sleep aids are used to increase slow-wave sleep, then sleep duration is improved, but REM sleep is disrupted
Solution Approach 1:
The bilayer structure separates the functions of sleep induction and sleep maintenance. The immediate-release herbal layer facilitates rapid transition to sleep without suppressing REM sleep, while the time-release melatonin layer maintains sleep duration and supports natural sleep stage cycling, including preserved REM sleep architecture.
Solution Approach 2:
The patent changes the release parameter of melatonin from immediate to time-release formulation, creating a gradual concentration profile that maintains therapeutic levels throughout the night. This parameter change allows sustained sleep duration while avoiding the abrupt suppression of natural sleep stage transitions that occurs with traditional hypnotics.
3Speed
If immediate release of all ingredients is used, then rapid sleep induction is achieved, but sleep maintenance is insufficient
Solution Approach 1:
The patent segments the dosage form into two layers with different release characteristics. The immediate-release layer provides rapid onset of relaxation effects within minutes, while the time-release melatonin layer provides sustained release over 6-8 hours to maintain sleep through the night, addressing both speed and duration requirements.
Solution Approach 2:
The immediate-release herbal layer performs preliminary relaxation and anxiety reduction before the full effect of melatonin takes hold. This preliminary action prepares the user for sleep onset, while the subsequent time-release melatonin maintains sleep continuity, creating a coordinated two-phase approach.
4Speed
If high doses of melatonin are released immediately, then sleep induction is enhanced, but sleep quality deteriorates due to disrupted sleep stages
Solution Approach 1:
The patent changes the release parameter of melatonin from immediate to time-release, creating a controlled concentration profile that avoids peak-related disruptions to sleep architecture. The gradual release maintains therapeutic levels throughout the night without the abrupt peaks that can suppress REM sleep and disrupt natural cycling, thereby preserving sleep quality.

AI summary
Compositions are disclosed for improved sleep quality and quantity including ingredients for both immediate release and controlled release. The invention provides improved supplemental compositions, and methods for administering same to a user, for enhancing the onset, quality, and duration of sleep in humans and animals. The supplemental composition may contain a combination of ingredients in proportions calculated to relieve stress, promote relaxation, and enhance sleep, including at least the following ingredients: L-Theanine, Skullcap Herb (Scutellaria lateriflora L.), Rhodiola (Rhodiola rosea L.), and Chamomile Flower (Matricaria Recutita). In addition, the supplemental composition may include the secondary ingredient Melatonin. The selection and amounts of the ingredients of the supplemental composition promote sleep onset, quality, and duration and may be provided for consumption at least one time daily, e.g., prior to sleep. The composition may be in a layered solid dosage form to provide controlled and sustained release of specific ingredients.
