Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a display unit is added to notify users of therapy status, then user awareness and reliability improve, but device complexity and portability deteriorate

Engineering Contradiction:

Improveuser awareness of therapy operationVSAvoiddevice structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical/display-based notification system with a physiological feedback system. The device detects changes in the user's skin potential (electrical property of the body) to determine therapy status and automatically provides feedback through the microcurrent stimulation itself, eliminating the need for separate display units or complex notification mechanisms.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The device uses the user's own physiological response (skin potential change) as the feedback mechanism. The body's electrical properties serve as both the target of therapy and the indicator of therapy status, allowing the system to self-monitor and self-report without external components.

Inventive Principle:

Principle #25Self-service

2Reliability

If a display unit is added to notify users of therapy status, then user awareness and reliability improve, but device portability worsens

Engineering Contradiction:

Improveuser awareness of therapy operationVSAvoiddevice portability

Core Design Contradiction:

ReliabilityVSWeight of moving object

Solution Approach 1:

The patent replaces physical display components with an electrical/physiological detection system. By measuring skin potential changes, the device eliminates heavy display units, buttons, and associated power consumption, resulting in a lighter, more portable device that maintains full user awareness functionality.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Device complexity

If no user notification mechanism is provided, then device simplicity and portability are maintained, but user reliability and awareness deteriorate

Engineering Contradiction:

Improvedevice structureVSAvoiduser awareness of therapy operation

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent implements a closed-loop feedback system where the device continuously monitors the user's skin potential and adjusts its operation accordingly. The detected physiological changes provide real-time feedback to both the control system and the user through modified stimulation patterns, ensuring reliable therapy delivery without adding complex external feedback components.

Inventive Principle:

Principle #23Feedback
