Solution Overview

Problem

Current medical devices for weight loss and constipation management are either dependent on long-term drug use, causing dehydration, or ineffective with increased abdominal fat, and lack a safe and effective in vivo solution for interacting with the human colonic wall to alleviate colon spasm and promote motility.

Innovation Solution

A vibration capsule device with a movement generation unit, control unit, wireless communication, and power supply, featuring configurable frequencies and duty cycles, sensors for feedback, and various motor types, designed for easy use and placement in the GI tract to promote health and weight loss without discomfort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If long-term drug use is employed for weight loss and constipation management, then the cathartic effect is achieved, but dependency and dehydration side effects occur

Engineering Contradiction:
Improvecathartic effectVSAvoiddependency and dehydration
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the chemical drug-based cathartic system with a mechanical vibration system. The vibration capsule generates controlled mechanical vibrations that directly stimulate colonic wall mechanics to promote peristalsis and stool discharge, eliminating the need for chemical laxatives and their associated side effects of dependency and dehydration.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The vibration capsule acts as an intermediary device between the user and the colonic function. Instead of drugs chemically interacting with the digestive system, the mechanical vibration capsule serves as a mediator that physically stimulates colonic motility through controlled vibrations, providing a non-invasive alternative that avoids harmful chemical interactions.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If in vitro message devices are used for weight loss and constipation, then some therapeutic effect is achieved, but the effect diminishes with increased abdominal fat

Engineering Contradiction:
Improvetherapeutic effectVSAvoideffectiveness with abdominal fat
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The vibration capsule is designed to be self-contained and self-powered, containing its own battery, vibration motor, and control systems. This allows it to deliver consistent mechanical vibrations directly to the colonic wall regardless of the user's body composition or abdominal fat level, overcoming the limitation of external devices that lose effectiveness with increased fat.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent employs mechanical vibration as the core therapeutic mechanism. The vibration capsule generates controlled mechanical oscillations that physically transmit through the abdominal wall to stimulate colonic peristalsis. This mechanical approach remains effective regardless of fat layer thickness, as the vibrations directly target the colonic muscle layer.

Inventive Principle:
Principle #18Mechanical vibration

3Reliability

If vibration capsule operates continuously to maximize therapeutic effect, then GI tract health improvement is enhanced, but patient discomfort increases

Engineering Contradiction:
ImproveGI tract health improvementVSAvoidpatient discomfort
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The vibration capsule implements periodic operation with alternating work and rest periods. During work periods, vibrations are delivered to stimulate colonic motility; during rest periods, the device remains inactive to allow the patient to experience minimal discomfort. This periodic pattern maintains therapeutic effectiveness while managing patient comfort levels.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The vibration capsule features dynamic control of vibration parameters including frequency, amplitude, and duration. The system can adjust vibration intensity and operational timing based on therapeutic needs and patient tolerance, transitioning between different vibration states to optimize both efficacy and comfort throughout the treatment period.

Inventive Principle:
Principle #15Dynamics

4Reliability

If vibration capsule is designed with comprehensive control and sensing units for optimal performance, then clinical effectiveness is maximized, but device complexity increases

Engineering Contradiction:
Improveclinical effectivenessVSAvoiddevice structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The vibration capsule integrates multiple functions into a single compact device: vibration generation for therapeutic stimulation, sensors for detecting colonic conditions and patient response, wireless communication for data transmission and remote monitoring, and power management for extended operation. This multi-functionality maximizes clinical effectiveness while containing the device within a manageable form factor.

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