Solution Overview

Problem

Existing perineal probes lack the ability to precisely select and stimulate specific muscle groups, leading to ineffective treatment of incontinence issues.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional circularly symmetric probes with metal electrodes are used, then the device structure is simple and economical, but the ability to precisely select and stimulate specific muscle groups is lost

Engineering Contradiction:
Improveprecision of muscle group selectionVSAvoidprobe structure complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The probe divides the electrode surface into multiple distinct zones (anodal, cathodal, neutral) that can be independently controlled. This segmentation allows selective stimulation of different muscle groups by activating specific electrode zones, resolving the contradiction between precision and complexity by organizing complexity into functional segments rather than a monolithic structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the electrode surface are assigned different electrical properties (anodal, cathodal, neutral) to create local quality variations. This enables precise targeting of specific muscle groups by applying appropriate electrical characteristics to specific locations, achieving high measurement precision while maintaining relatively simple overall device structure.

Inventive Principle:
Principle #3Local quality

2Ease of manufacture

If traditional probes with unilateral or flat electrodes are used, then the manufacturing process is simple, but the treatment effectiveness for specific muscle groups is reduced

Engineering Contradiction:
Improveease of probe manufacturingVSAvoidtreatment effectiveness
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The probe incorporates adjustable and reconfigurable electrode configurations that can be dynamically adjusted during treatment. This allows the same simple probe structure to be adapted for different treatment scenarios and muscle groups, maintaining ease of manufacture while significantly improving treatment effectiveness through flexible configuration.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The probe utilizes variable electrical parameters (polarity, intensity, duration) that can be changed without physical modification to the device. By changing these parameters, the same simple probe structure can effectively treat different muscle groups, achieving high reliability without complex manufacturing requirements.

Inventive Principle:
Principle #35Parameter changes
