Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If LED light source unit operates continuously to provide heating function, then treatment effectiveness is improved, but temperature rises to cause low-temperature burn

Engineering Contradiction:

Improveheating temperatureVSAvoidlow-temperature burn

Core Design Contradiction:

TemperatureVSObject-affected harmful factors

Solution Approach 1:

The LED light source unit operates in periodic pulses rather than continuously. The driving control unit controls the LED to emit light in intervals, providing heating during active periods while allowing cooling during off periods, thus preventing temperature from rising to burn levels while maintaining therapeutic heating effect

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system dynamically adjusts the LED operating state between on and off through PWM control. This dynamic operation allows real-time temperature management, switching between heating mode and cooling mode to maintain safe operating temperature range

Inventive Principle:

Principle #15Dynamics

2Illumination intensity

If LED driving control increases power to enhance treatment effect, then light emission intensity is improved, but temperature control becomes difficult and burn risk increases

Engineering Contradiction:

ImproveLED light emission intensityVSAvoidLED unit temperature

Core Design Contradiction:

Illumination intensityVSTemperature

Solution Approach 1:

By using periodic pulse-width modulation, the system delivers high-intensity light in controlled pulses rather than sustained continuous operation. This allows achieving effective treatment intensity while limiting total energy input and temperature accumulation through the off-periods between pulses

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system changes the driving parameters of the LED by controlling pulse width and duty cycle through PWM. This allows independent optimization of light emission intensity during active periods while controlling average power input and temperature rise through parameter adjustment of the pulse waveform

Inventive Principle:

Principle #35Parameter changes

3Ease of operation

If existing Y-zone care products are used for cleaning and moisturizing, then hygiene maintenance is improved, but long-term care effectiveness is limited due to time and space constraints

Engineering Contradiction:

Improveusage convenienceVSAvoidlong-term care duration

Core Design Contradiction:

Ease of operationVSDuration of action of moving object

Solution Approach 1:

The device combines multiple functions including LED phototherapy for treatment, heating for comfort and circulation, and is designed to be worn internally like underwear. This multi-functional integration provides comprehensive long-term care beyond simple cleaning, addressing treatment, hygiene, and comfort needs continuously

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The device is designed for self-wearing as internal underwear that provides continuous treatment and care without requiring external application or frequent user intervention. The disposable pad design enables easy replacement for maintenance while the device itself provides ongoing therapeutic function

Inventive Principle:

Principle #25Self-service
