Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If electrodes or clamps are used to generate static electricity for pain relief, then the electrostatic field can be effectively generated, but the device becomes invasive and less comfortable for patients

Engineering Contradiction:
Improveeffectiveness of pain reliefVSAvoidcomfort and invasiveness
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the mechanical contact system (electrodes and clamps that require direct skin contact) with a friction-based electrostatic generation system. The brush assembly generates static electricity through friction with the polymer sheet, eliminating the need for invasive electrodes while maintaining therapeutic effectiveness through contactless application to the body surface.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The polymer sheet acts as an intermediary between the brush assembly and the patient's body. It receives the electrostatic charge from the brush through friction and then transfers it to the body surface through gentle contact, mediating the interaction between the generation mechanism and the treatment target without requiring invasive electrodes.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If a portable handheld device is designed without electrodes or clamps, then the device becomes less invasive and more comfortable, but the ability to effectively generate static electricity for pain relief is compromised

Engineering Contradiction:
Improvecomfort and non-invasivenessVSAvoideffectiveness of pain relief
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The brush assembly generates its own electrostatic charge through self-friction with the polymer sheet, requiring no external power source or complex electrode connections. This self-powered mechanism simplifies the device structure while maintaining therapeutic effectiveness, allowing portable handheld operation without compromising pain relief capability.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent changes the fundamental parameter of electrostatic generation from electrode-based voltage application to friction-based charge generation. By using materials with appropriate triboelectric properties (brush and polymer), the system generates sufficient static electricity through mechanical friction alone, achieving effective pain relief without invasive components.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If a brush assembly and polymer sheet are used to generate static electricity through rubbing, then the device becomes portable and non-invasive, but the control and precision of electrostatic field generation may be reduced

Engineering Contradiction:
Improveportability and non-invasivenessVSAvoidcontrol of electrostatic field
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The brush assembly is designed to rotate at controlled speeds (e.g., 60-240 RPM) to dynamically regulate the rate of electrostatic charge generation. This rotational control provides precise adjustment of the electrostatic field intensity, allowing the device to adapt to different treatment requirements while maintaining portability and non-invasive operation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The device incorporates feedback mechanisms to monitor and adjust the electrostatic field generation in real-time. By detecting the charge accumulation on the polymer sheet and adjusting the brush rotation speed or pressure, the system maintains optimal control precision despite the mechanical friction-based generation method, ensuring consistent therapeutic效果.

Inventive Principle:
Principle #23Feedback
