Solution Overview

Problem

Current obesity treatment methods, such as surgical procedures and endoscopic devices, are invasive, lead to unsustained weight loss, and face complications like improper device positioning and migration, causing technical difficulties and requiring additional invasive procedures.

Innovation Solution

Development of magnetic devices that can be implanted in the stomach to induce satiety, allowing for non-invasive control and adjustment using external magnetic forces, enabling remote positioning and stimulation of the stomach to manage weight loss effectively.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If surgical procedures or endoscopic devices are used for obesity treatment, then weight loss can be achieved, but the procedures are invasive and lead to complications such as improper device positioning and migration

Engineering Contradiction:

Improvedevice positioning stabilityVSAvoidinvasiveness and complications

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces mechanical control systems with a magnetic field-based control system. An external magnetic device can non-invasively position and adjust an intragastric device containing magnetic material, eliminating the need for surgical intervention while maintaining reliable device positioning and preventing migration.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a magnetic field as an intermediary between the external controller and the intragastric device. The magnetic field acts as a mediator that can transmit control signals through the body wall without physical contact, enabling non-invasive adjustment of device position and configuration.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If space-occupying devices are placed in the stomach to induce satiety, then food intake can be reduced, but the devices are uncontrolled and free-floating causing undesired migration and bowel obstruction

Engineering Contradiction:

Improvesatiety inductionVSAvoiddevice position control

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent replaces passive mechanical floating devices with actively controllable magnetic devices. The intragastric device contains magnetic material that responds to external magnetic fields, allowing precise positioning and stabilization to prevent migration and bowel obstruction while maintaining satiety induction.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent transforms the intragastric device from a static, passive object to a dynamic, controllable system. The device can be actively positioned and adjusted using external magnetic fields, enabling it to adapt to different therapeutic requirements and maintain optimal position throughout treatment.

Inventive Principle:

Principle #15Dynamics

3Productivity

If intragastric devices are inserted to treat obesity, then weight loss can be achieved, but invasive procedures are required for insertion and removal

Engineering Contradiction:

Improveweight loss effectivenessVSAvoidprocedure invasiveness

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent replaces surgical and endoscopic mechanical insertion/removal procedures with non-invasive magnetic manipulation. The intragastric device can be inserted and removed using external magnetic fields that guide the device through the esophagus and out of the body without requiring incisions or complex endoscopic equipment.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Adaptability or versatility

If magnetic devices are used for non-invasive control, then device positioning can be adjusted remotely, but the system requires external magnetic devices and coordination

Engineering Contradiction:

Improveremote adjustment capabilityVSAvoidsystem coordination requirements

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent designs the intragastric device with multi-functionality, combining satiety induction, magnetic positioning, and magnetic insertion/removal capabilities in a single device. The external magnetic device serves multiple purposes including positioning, adjustment, and retrieval, reducing the need for separate specialized equipment.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A minimally invasive system and method for providing weight loss by inducing the feeling of satiety whereby an intragastric device is inserted into the gastric lumen via the esophagus and an external magnetic device is used as needed to magnetically attract the intragastric device towards the inner wall of the stomach and impart tactile stimulation sufficient to induce the feeling of satiety.
