Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional electrode designs and placements are used, then the system structure is simple, but the ability to adjust signal flow geometry through tissues is limited

Engineering Contradiction:
Improveadjustment of signal flow geometryVSAvoidelectrode system design
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The electrode system is divided into multiple independently controllable electrode groups (first electrode group, second electrode group, third electrode group, fourth electrode group) positioned at different locations. Each group can be independently activated to create different signal flow geometries through the tissue, enabling versatile adjustment without requiring a completely different system design for each configuration.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system employs dynamic control of electrode activation patterns, where different combinations of electrode groups are activated based on treatment requirements. The signal flow geometry can be dynamically adjusted by changing which electrode groups are active and their respective signal parameters, allowing the system to adapt to different tissue depths and target locations.

Inventive Principle:
Principle #15Dynamics

2Measurement precision

If multiple electrode groups are used to adjust signal flow geometry, then treatment precision is improved, but device complexity increases

Engineering Contradiction:
Improvetreatment precisionVSAvoidelectrode system structure
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The multiple electrode groups share common structural elements including the signal generator, controller, and housing. Each electrode group can serve multiple functions depending on activation patterns - they can be used individually for targeted stimulation or in combination for broader coverage. This multi-functionality reduces the need for completely separate systems for different treatment scenarios.

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

Solution Approach 2:

The system merges multiple electrode groups into a single integrated device with shared control electronics and power supply. The first, second, third, and fourth electrode groups are all controlled by the same signal generator and controller unit, consolidating what could have been separate devices into one unified system that achieves high treatment precision.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If signals are delivered to multiple electrode groups simultaneously, then treatment effectiveness is improved, but energy consumption increases

Engineering Contradiction:
Improvetreatment effectivenessVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system employs periodic or alternating activation of different electrode groups rather than continuous simultaneous activation. The controller can activate electrode groups in sequences or cycles, delivering signals to different groups at different time intervals. This periodic action maintains treatment effectiveness by providing comprehensive coverage while reducing peak energy consumption compared to continuous simultaneous activation of all groups.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system dynamically adjusts signal delivery parameters including amplitude, duration, and activation timing for each electrode group based on real-time feedback and treatment requirements. This dynamic control allows the system to optimize energy distribution, delivering higher energy to specific groups when needed while using lower energy or inactive states for other groups, thereby maintaining effectiveness while managing overall energy consumption.

Inventive Principle:
Principle #15Dynamics
