Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a control signal is transmitted to multiple electrode pads through a single channel, then the device complexity is reduced, but the ability to focus electrical stimulation on a specific body part deteriorates

Engineering Contradiction:

Improvecontrol channel structureVSAvoidstimulation positioning accuracy

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

The patent divides the control system into multiple independent channels, with each channel dedicated to controlling a specific electrode pad or group of pads. This segmentation allows independent control of each electrode pad, enabling precise targeting of specific body parts while maintaining manageable device complexity through modular architecture.

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If electrical muscle stimulation is applied uniformly through the electrode pads, then the ease of operation is improved, but the ability to achieve rolling massage benefit deteriorates

Engineering Contradiction:

Improveoperation simplicityVSAvoidmassage pattern adaptability

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic control of electrode pad activation sequences, allowing the system to transition between different stimulation patterns including rolling massage modes. The control unit can dynamically adjust which electrodes are activated and in what sequence, providing versatile massage patterns while maintaining simple operation through automated program selection.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent employs periodic activation patterns where electrode pads are stimulated in repeating sequences along the body. This periodic action creates the rolling massage effect by systematically moving the stimulation pattern from one body region to another, achieving adaptability through programmed cycles while keeping operation simple through preset modes.

Inventive Principle:

Principle #19Periodic action

3Productivity

If multiple electrode pads are activated simultaneously, then the productivity of muscle stimulation is improved, but the ability to provide sequential rolling massage deteriorates

Engineering Contradiction:

Improvemuscle stimulation efficiencyVSAvoidsequential massage timing

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The control unit is pre-programmed with sequential activation patterns that automatically coordinate the timing of multiple electrode pads. This preliminary action setup allows the system to efficiently activate multiple pads in the correct sequence for rolling massage without requiring real-time manual coordination, maintaining both productivity and proper timing.

Inventive Principle:

Principle #10Preliminary action
