Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional strap adjustment mechanisms are used, then the device can be adjusted to different tightness levels, but the adjustment accuracy is low and multiple operations are required
Solution Approach 1:
The patent replaces traditional mechanical adjustment mechanisms with an optical detection system. A color sensor detects the color of detection parts at different positions on the strap to determine overlapping length, substituting mechanical measurement with optical sensing for higher precision and fewer operations
Solution Approach 2:
The patent uses detection parts coated with UV paint or phosphor of different colors at different positions along the strap. The color sensor identifies these colors to determine the overlapping length, directly linking color information to tightness measurement for accurate one-step adjustment
2Adaptability or versatility
If the strap length is adjusted to fit different users, then the wearable device can accommodate various users, but the tightness adjustment accuracy is low
Solution Approach 1:
The patent divides the strap into multiple detection parts at different positions, each with distinct color characteristics. This segmentation allows the system to detect specific positions along the strap to determine overlapping length, enabling precise measurement while maintaining adaptability for different users
Solution Approach 2:
The patent introduces detection parts with different colors as an intermediary between the strap structure and the color sensor. These detection parts serve as visual markers that enable the sensor to accurately determine overlapping length without direct mechanical contact, improving measurement precision while preserving user adaptability
