Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single-function massager design is used, then the device complexity is low, but the massage effectiveness and functionality are limited

Engineering Contradiction:
Improvemassage functionsVSAvoiddevice structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The massager integrates multiple massage functions including cold compress, hot compress, and electrical stimulation into a single device. The semiconductor refrigeration sheet enables temperature control for cold and hot compress functions, while the electrode plates provide electrical stimulation for muscle exercise, allowing one device to perform multiple massage effects simultaneously

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

Solution Approach 2:

The patent combines the semiconductor refrigeration sheet with electrode plates on the same contact side plate, merging temperature control and electrical stimulation functions into a unified massage system. This integration allows both cold/hot compress and muscle stimulation to be applied together, enhancing overall massage effectiveness

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If semiconductor refrigeration sheets and electrode plates are integrated, then the massage effectiveness is improved, but the device complexity increases

Engineering Contradiction:
Improvemassage effectVSAvoidcomponent integration
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The massager is divided into distinct functional modules: the semiconductor refrigeration sheet for temperature control, the electrode plates for electrical stimulation, and the control device for coordinating operations. This segmentation allows each component to perform its specific function independently while working together as a unified system, managing complexity through modular design

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If dual-temperature massage modes are implemented, then the massage effectiveness is enhanced, but the energy consumption increases

Engineering Contradiction:
Improvetemperature controlVSAvoidenergy consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The control device enables periodic switching between cold and hot compress modes using the semiconductor refrigeration sheet. The system can alternate between cooling and heating cycles, providing dual-temperature massage effects while managing energy consumption through controlled, periodic operation rather than continuous operation at maximum capacity

Inventive Principle:
Principle #19Periodic action
