Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If thermal treatment is used for muscle contraction, then treatment effectiveness is improved, but temperature distribution becomes non-homogeneous and adverse events occur

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSTemperature

Solution Approach 1:

The patent combines magnetic field treatment with thermal treatment to create a hybrid therapy system. The magnetic field component induces muscle contraction through electromagnetic induction while the thermal component provides homogeneous heating. This merging allows the system to achieve both effective muscle stimulation and uniform temperature distribution, avoiding the non-homogeneous heating problems of pure thermal treatment.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The magnetic field acts as an intermediary mechanism to achieve muscle contraction without relying solely on thermal effects. By using electromagnetic induction to directly stimulate muscle fibers, the system reduces dependence on high-intensity thermal treatment, thereby achieving more homogeneous temperature distribution while maintaining treatment effectiveness.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If high-powered magnetic field is used for muscle contraction, then treatment effectiveness is improved, but pain and adverse events increase

Engineering Contradiction:

Improvemuscle contraction efficiencyVSAvoidpain and adverse events

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system employs periodic or pulsed magnetic field application rather than continuous high-powered fields. This periodic action allows muscle fibers to contract and relax in a controlled manner, reducing pain and adverse events while maintaining contraction effectiveness. The pulsed nature of the treatment gives tissues time to recover between stimuli.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system optimizes magnetic field parameters such as frequency, amplitude, and pulse duration to achieve effective muscle contraction at lower power levels. By carefully adjusting these parameters, the treatment maintains therapeutic effectiveness while minimizing pain and adverse events associated with high-powered continuous fields.

Inventive Principle:

3Productivity

If conventional treatment methods are used alone, then treatment simplicity is maintained, but treatment outcomes are insufficient

Engineering Contradiction:

Improvetreatment outcome effectivenessVSAvoidtreatment method complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The treatment system is designed with multi-functionality, capable of delivering both magnetic field stimulation and thermal treatment through an integrated platform. This universal approach allows a single device to perform multiple therapeutic functions, improving treatment outcomes without requiring multiple separate treatment sessions or devices.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system dynamically adjusts treatment parameters based on real-time feedback from sensors monitoring muscle response and temperature. This dynamic adaptation allows the treatment to optimize its effectiveness during each session while maintaining safety, balancing the complexity of the combined modality with intelligent control that simplifies the user experience.

Inventive Principle:

If repeated high-intensity magnetic pulses are applied, then muscle contraction effectiveness is improved, but treatment duration increases

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system maintains continuous useful action by combining magnetic field-induced muscle contraction with simultaneous thermal treatment. While magnetic pulses are being applied to stimulate muscle fibers, the thermal component continues to provide homogeneous heating, ensuring that both therapeutic mechanisms work concurrently rather than sequentially, thereby reducing total treatment time.

Inventive Principle:

Principle #20Continuity of useful action

Solution Approach 2:

By using optimized periodic magnetic pulses with appropriate frequency and duty cycle, the system achieves effective muscle contraction in shorter bursts. The periodic nature allows for efficient energy delivery that maintains contraction effectiveness while reducing the total duration compared to continuous or overly frequent pulsing.

Inventive Principle:

Principle #19Periodic action
