Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If static sensibility evaluation methods are used in product design, then design quality can be improved, but dynamic control capability during appliance operation cannot be achieved
Solution Approach 1:
The patent transitions from static sensibility evaluation to dynamic sensibility control by implementing real-time biometric monitoring during appliance operation. The system continuously adjusts control parameters based on live operator physiological data, enabling the appliance to adapt dynamically to operator comfort levels while maintaining design quality standards.
Solution Approach 2:
The patent implements a closed-loop feedback system where biometric sensors continuously monitor operator physiological states (heart rate, skin conductance, temperature) and feed this information back to the control unit. The control unit then adjusts appliance operation parameters in real-time based on this feedback, creating a dynamic adaptability mechanism that was absent in static design evaluation methods.
2Measurement precision
If biometric monitoring is implemented to detect operator comfort levels, then operator sensibility can be measured in real-time, but system complexity increases
Solution Approach 1:
The patent integrates multiple biometric sensing functions (heart rate monitoring, skin conductance measurement, temperature sensing) into a unified control system. The control unit processes multiple types of physiological data simultaneously to comprehensively assess operator comfort levels, achieving high measurement precision while managing system complexity through functional integration.
Solution Approach 2:
The control unit serves as an intermediary that processes complex biometric data from multiple sensors and translates it into simplified control parameter adjustments. This intermediary layer manages the complexity by abstracting the detailed sensor processing while maintaining accurate comfort level detection through sophisticated algorithms.
3Ease of operation
If control parameters are adjusted based on operator biometric data, then operator comfort can be improved, but control precision requirements increase
Solution Approach 1:
The patent adjusts multiple control parameters (operation speed, power output, operational mode) based on operator biometric data. By changing these parameters dynamically according to real-time comfort level assessments, the system improves operator ease of operation while maintaining precise control through coordinated parameter adjustment rather than relying on single-parameter precision.

AI summary
A sensibility meter detects biometric information relating to an operator corresponding to an output from a target appliance, and determines a comfort level of the operator based on the biometric information. A first control unit determines a second target value relating to the output based on a difference between a first target value relating to the comfort level and the comfort level. A second control unit determines a control input to the target appliance based on a difference between the second target value and the output. A δ setting unit performs weighting corresponding to an operation level of the operator, for an operation input to the target appliance by the operator, and for the control input. An adder adds the weighted operation input and control input, and inputs the resultant to the target appliance.
