Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If current is supplied to both electrodes simultaneously, then treatment coverage is improved, but battery life deteriorates

Engineering Contradiction:

Improvetreatment effectivenessVSAvoidbattery life

Core Design Contradiction:

ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The patent implements periodic action by alternating current supply between first and second electrodes in time intervals. The control unit switches between supplying current to the first electrode, then the second electrode, creating a periodic stimulation pattern that maintains treatment effectiveness while reducing overall power consumption compared to continuous simultaneous supply.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The patent applies dynamics by making the electrode selection dynamic rather than static. The control unit dynamically determines which electrode receives current based on predetermined conditions and time intervals, allowing the system to adapt current distribution while maintaining therapeutic benefits and extending battery operation.

Inventive Principle:

Principle #15Dynamics

2Reliability

If current is supplied to both electrodes simultaneously, then stimulation coverage is improved, but power consumption increases

Engineering Contradiction:

Improvetreatment effectivenessVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic action by alternating current supply between first and second electrodes in time intervals. The control unit switches between supplying current to the first electrode, then the second electrode, creating a periodic stimulation pattern that maintains treatment effectiveness while reducing overall power consumption compared to continuous simultaneous supply.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The patent applies partial action by providing high-frequency current to only one electrode at a time rather than both simultaneously. This partial stimulation approach is sufficient to achieve therapeutic effects while significantly reducing the total energy consumption of the device.

Inventive Principle:

Principle #16Partial or excessive action

3Reliability

If current is supplied to both electrodes simultaneously, then treatment intensity is improved, but battery capacity depletes faster
