Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electromagnetic wave therapy devices are used to treat skin elasticity, then treatment effectiveness is improved, but safety control for vulnerable areas deteriorates
Solution Approach 1:
The device performs preliminary detection of skin contact through the coupler measuring reflected waves before emitting therapeutic electromagnetic waves. This preliminary action ensures that waves are only emitted when proper skin contact is confirmed, preventing accidental exposure of vulnerable areas while maintaining treatment effectiveness.
Solution Approach 2:
The system continuously monitors the ratio of traveling waves to reflected waves through the coupler and uses this feedback to control the electromagnetic wave generator. When the ratio indicates proper skin contact, wave emission is activated; when the ratio changes indicating improper contact or proximity to vulnerable areas, emission is prevented, thus ensuring safety while maintaining treatment efficacy.
2Ease of operation
If electromagnetic waves are emitted without contact detection, then device operation is simplified, but harmful absorption by body increases
Solution Approach 1:
The device performs self-verification through the coupler and comparer/determiner to automatically detect skin contact and control wave emission. This self-service mechanism eliminates the need for manual verification by the operator, maintaining operational simplicity while preventing harmful absorption by ensuring waves are only emitted during proper skin contact.
3Object-affected harmful factors
If contact detection mechanism is added, then safety is improved, but device complexity increases
Solution Approach 1:
The coupler serves multiple functions: it transmits electromagnetic waves from the generator to the emitter, measures the ratio of traveling to reflected waves for contact detection, and provides feedback for safe operation control. This multi-functionality reduces the need for separate components, thereby improving safety while minimizing the increase in device complexity.
