Solution Overview

Problem

Current obesity treatments are ineffective due to lack of efficacy or unacceptable side effects, and there is a need for safe and effective therapies for weight management, particularly in conjunction with smoking cessation, where weight gain is a significant barrier.

Innovation Solution

Development of 5-HT2C receptor agonists, such as those listed in Table A, which are administered to individuals to decrease food intake, induce satiety, and manage weight, while also aiding in smoking cessation and preventing associated weight gain.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If current obesity treatments are used, then weight loss may be achieved, but unacceptable side effects occur

Engineering Contradiction:
Improveweight lossVSAvoidside effects
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The patent applies parameter changes by developing novel 5-HT2C receptor agonist compounds with optimized molecular structures (Formula 1 and analogs) that achieve effective weight loss while reducing harmful side effects. The chemical parameters including substitution patterns, stereochemistry, and molecular weight are systematically modified to improve the therapeutic index.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent uses 5-HT2C receptor agonists as intermediary substances that mediate between the nervous system and metabolic processes. These compounds act through the 5-HT2C receptor pathway to regulate appetite and energy expenditure, providing a mechanistic bridge that achieves weight loss through physiological regulation rather than direct metabolic interference, thereby reducing side effects.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If diet and lifestyle advice is given, then obesity management is recommended, but patient compliance is difficult to maintain

Engineering Contradiction:
ImprovecomplianceVSAvoidtreatment effectiveness
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent enables self-service by providing patients with an autonomous pharmacological solution that works independently of behavioral modification. The 5-HT2C agonist compounds automatically regulate appetite and satiety signals, allowing patients to maintain weight loss without requiring constant self-monitoring or willpower, thus improving compliance while ensuring reliable treatment effectiveness.

Inventive Principle:
Principle #25Self-service

3Object-affected harmful factors

If smoking cessation is pursued, then health benefits are achieved, but weight gain occurs as a barrier

Engineering Contradiction:
Improvehealth risks from smokingVSAvoidweight gain
Core Design Contradiction:
Object-affected harmful factorsVSQuantity of substance

Solution Approach 1:

The patent applies preliminary anti-action by pre-treating or concurrently treating smoking cessation patients with 5-HT2C agonist compounds to prevent the anticipated weight gain. This proactive approach counteracts the compensatory eating behavior that typically follows smoking cessation, allowing patients to achieve both smoking cessation and weight management goals simultaneously.

Inventive Principle:
Principle #9Preliminary anti-action
