Solution Overview

Problem

The cognitive-enhancing properties of American Ginseng (Panax quinquefolius) have not been well understood, and existing research on Asian Ginseng does not adequately address its potential benefits for neurocognitive function.

Innovation Solution

Administering American Ginseng, particularly in doses of 100 mg and 200 mg, improves working memory, attention, and calmness in healthy young adults, with all doses showing cognitive benefits across various tasks and time points, and the 100 mg dose enhancing calmness at 3 and 6 hours.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If Asian Ginseng is administered to improve cognitive function, then learning and memory are enhanced, but higher dosages may impair cognitive function and cause side effects

Engineering Contradiction:

Improvecognitive function enhancementVSAvoidcognitive impairment from high dosage

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies parameter changes by switching from Asian Ginseng to American Ginseng, a different species with potentially different pharmacological properties. This species substitution allows for exploring a new dosage-response profile that may avoid the inverted-U-shaped curve limitations of Asian Ginseng, where optimal cognitive enhancement occurs only within a narrow dosage range. The patent investigates whether American Ginseng exhibits a more favorable dose-response relationship that maintains cognitive benefits across a broader dosage spectrum.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent employs American Ginseng as an alternative to Asian Ginseng, potentially offering a more accessible and sustainable option. American Ginseng may provide similar or superior cognitive benefits with a more favorable safety profile, making it a preferable choice for long-term cognitive enhancement strategies without the dosage-related impairments associated with Asian Ginseng.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

2Reliability

If American Ginseng is used as a cognitive enhancer, then cognitive benefits may be achieved, but its efficacy and optimal dosage remain unknown compared to Asian Ginseng

Engineering Contradiction:

Improvecognitive enhancement efficacyVSAvoidlack of knowledge on American Ginseng cognition effects

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The patent conducts preliminary research to establish the cognitive-enhancing properties of American Ginseng before it can be widely utilized. By investigating its effects on cognitive function, memory, and attention in controlled studies, the patent generates foundational knowledge about its efficacy, optimal dosage ranges, and mechanism of action. This preliminary characterization enables future applications and comparisons with Asian Ginseng based on evidence rather than speculation.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent uses American Ginseng as an intermediary substance to bridge the gap in knowledge between traditional Asian Ginseng research and the need for alternative cognitive enhancers. By systematically studying American Ginseng's effects, the research fills the information gap about North American ginseng species and provides a basis for comparing different ginseng types, ultimately expanding the available options for cognitive enhancement.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

Disclosed are methods of enhancing neurocognitive function by administering of American Ginseng. Preferred dosages in the range of 5 to 50 mg total genosides enhance cognitive function—including, improvement of working memory (WM) performance, attentional performance (e.g., Choice Reaction Time accuracy), and calmness.
