Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual adjustment of operating parameters is used, then user control is maintained, but determination accuracy of fabric type deteriorates
Solution Approach 1:
The sensor system automatically detects fabric type and determines optimal operating parameters without user intervention. The processing unit analyzes sensor data (capacitance, thickness, texture) and autonomously selects treatment parameters, eliminating the need for manual lookup and adjustment while improving accuracy through objective measurement
Solution Approach 2:
The patent replaces manual mechanical adjustment (thermostat dial) with an automated sensor-based system. Electrical sensors measure fabric properties and the processing unit electronically determines operating parameters, substituting physical manual control with automated electronic control based on measured physical quantities
2Measurement precision
If multiple sensing mechanisms are used, then fabric type determination accuracy improves, but device complexity increases
Solution Approach 1:
The patent combines multiple sensing functions into a single integrated sensor assembly. The first and second sensors (measuring different properties like capacitance and thickness) are positioned to simultaneously contact the fabric, merging multiple measurement capabilities into one unified device that determines fabric type through combined data analysis
Solution Approach 2:
The sensor system is designed to perform multiple measurement functions through a single device structure. The sensing mechanism can detect various fabric properties (electrical characteristics, thickness, texture) using the same basic sensor assembly, making the device universally applicable for different fabric types without requiring separate specialized sensors
