Solution Approach 1:

The patent integrates multiple conductive pads into a single garment structure, combining what were previously separate positioning components into one unified wearable item. This merging maintains the multi-point stimulation capability while eliminating the complexity of positioning individual pads, directly resolving the contradiction between stimulation effectiveness and positioning ease.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The garment serves multiple functions simultaneously: it provides mechanical support/compression while integrating electrical stimulation through conductive pads. This multi-functionality allows the single device to deliver effective muscle stimulation without requiring separate positioning steps for multiple components, addressing both reliability and ease of operation.

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

2Measurement precision

If multiple conductive pads are used for targeted stimulation, then treatment precision is improved, but device complexity increases

Engineering Contradiction:
Improvemuscle targeting precisionVSAvoiddevice complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines multiple conductive pads into a single integrated garment, maintaining the precision of multi-point targeting while reducing device complexity. The garment structure itself becomes the delivery mechanism, eliminating the need for complex separate components and simplifying the overall system while preserving targeting precision.

Inventive Principle:
