Innovation Solution

A vibration capsule device with a movement generation unit, control unit, wireless communication, and power supply, featuring sensors and adjustable vibration frequencies and duty cycles, designed for safe and effective interaction with the GI tract to promote health and weight loss without discomfort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a drug is used for weight loss or constipation treatment, then the therapeutic effect is achieved, but drug dependency and dehydration side effects occur

Engineering Contradiction:
Improvetherapeutic effectVSAvoiddrug dependency and dehydration
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces pharmacological treatment with a mechanical vibration system. The vibration capsule uses an eccentric rotating mass mechanism to generate controlled vibrations that mechanically stimulate the GI tract, substituting chemical drug action with physical mechanical stimulation to achieve therapeutic effects without drug-related side effects

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

Solution Approach 2:

The vibration capsule employs periodic vibration cycles with adjustable duty cycles (e.g., 5 seconds on, 5 seconds off). This periodic mechanical stimulation promotes GI motility and prevents colon spasm through rhythmic contractions, eliminating the need for continuous drug administration and avoiding associated dependency and dehydration issues

Inventive Principle:
Principle #19Periodic action

2Reliability

If an in vitro message device is used for weight loss or constipation, then initial 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 swallowed and nested within the GI tract environment. This internal placement allows the device to directly contact and vibrate the colonic and intestinal walls from within, ensuring effective mechanical stimulation regardless of external abdominal fat layers that would block in vitro devices

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The vibration capsule delivers localized mechanical stimulation directly to the target GI tract segments. The focused vibration energy is applied precisely where needed in the colon or small intestine, ensuring effective treatment independent of the patient's body composition or abdominal fat distribution

Inventive Principle:
Principle #3Local quality

3Productivity

If vibration frequency is increased to improve therapeutic effect, then colonic motility is enhanced, but patient discomfort increases

Engineering Contradiction:
Improvecolonic motility enhancementVSAvoidpatient discomfort
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The vibration capsule features dynamically adjustable vibration parameters including frequency (e.g., 5-20 Hz), amplitude, and duty cycle. The control system allows real-time modification of these parameters to optimize therapeutic effect while maintaining patient comfort, adapting the mechanical stimulation to individual patient tolerance and treatment response

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The device incorporates sensors that detect patient responses and provide feedback to the control system. This feedback mechanism allows the vibration parameters to be automatically adjusted to maintain optimal therapeutic effect while preventing excessive vibration that would cause discomfort or pain

Inventive Principle:
Principle #23Feedback

4Reliability

If continuous vibration is applied to maintain therapeutic effect, then colon spasm relief is sustained, but energy consumption increases

Engineering Contradiction:
Improvetherapeutic effect sustainabilityVSAvoidpower supply consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The vibration capsule operates in periodic cycles with adjustable duty cycles (e.g., 5 seconds vibration, 5 seconds rest). This intermittent operation sustains therapeutic effect through rhythmic stimulation while significantly reducing average power consumption compared to continuous vibration, extending battery life and enabling longer wear duration

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

Although vibration is intermittent, the periodic stimulation maintains continuous therapeutic effect by keeping the GI tract in a state of enhanced motility. The rhythmic on-off pattern prevents colon spasm recurrence and sustains weight loss effect without requiring constant energy input

Inventive Principle:
Principle #20Continuity of useful action
