Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If existing methods measure only specific physiological parameters at specific locations, then the measurement device remains simple and focused, but the evaluation becomes incomplete and lacks comprehensive insight into stress responses
Solution Approach 1:
The patent divides the physiological measurement system into multiple independent measurement channels, each targeting specific contact points on the body. By segmenting the measurement locations (e.g., multiple acupuncture points, skin areas) and parameter types (electrical, thermal, mechanical), the system achieves comprehensive coverage while maintaining modular simplicity in each measurement unit.
Solution Approach 2:
The patent creates a multi-functional measurement device that can simultaneously measure multiple physiological parameters (electrical properties, temperature, moisture) at multiple contact points. This universal device replaces several single-purpose devices, providing comprehensive stress response evaluation through integrated sensing capabilities.
2Loss of information
If multiple contact points are measured simultaneously, then comprehensive stress response evaluation is achieved, but the complexity of data analysis and comparison increases
Solution Approach 1:
The patent establishes baseline readings at multiple contact points before applying stressors. This preliminary measurement phase creates reference data that simplifies subsequent analysis by providing predetermined comparison points, reducing the complexity of evaluating stress responses against known pre-stress states.
Solution Approach 2:
The patent implements a feedback mechanism where measurements from multiple contact points are continuously compared against baseline readings. The system provides feedback on whether stress responses are symmetrical or asymmetrical, automatically categorizing results as favorable or unfavorable, thereby reducing manual analysis complexity.
3Measurement precision
If physiological measurements are taken before and after stimulus application, then stress response patterns can be identified, but the measurement process becomes more complex and time-consuming
Solution Approach 1:
The patent employs periodic measurement cycles: baseline measurement phase, stimulus application phase, and post-stressor measurement phase. This structured periodic approach organizes the complex multi-point measurements into manageable temporal segments, reducing overall process time while maintaining measurement precision for pattern identification.

Function Achieved in This Case
Enables comprehensive evaluation of stress responses, allowing for the identification of favorable or unfavorable physiological states and providing insights for improving health conditions through targeted interventions.
Implementation Method 1
Galvanic Skin Response (GSR) devices, also known as electrodermal response (EDR), have been used to obtain biofeedback from individuals. Specifically, GSR measures the electrical resistance of the skin and interprets the measurements as an image of activity in certain parts of the body
