Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional pressure sensors or inertial sensors are attached to the glove surface with circuit connections through flexible circuit boards, then hand gesture detection function is achieved, but the glove size increases, weight increases, and wearing comfort deteriorates
Solution Approach 1:
The patent replaces conventional mechanical pressure sensors and inertial sensors with a fabric-based sensor system that integrates sensing functions directly into the glove fabric structure. This substitution eliminates the need for separate sensor modules, flexible circuit boards, and complex mechanical connections, thereby significantly reducing glove weight while maintaining hand gesture detection capability
Solution Approach 2:
The patent merges the sensor functionality with the glove fabric itself by knitting the fabric-based pressure sensors and inertial sensors directly into the glove structure. This integration combines the protective function of the glove with the sensing function, eliminating separate components and reducing overall weight
2Reliability
If conventional pressure sensors or inertial sensors are attached to the glove surface with circuit connections through flexible circuit boards, then hand gesture detection function is achieved, but the glove size increases and wearing comfort deteriorates
Solution Approach 1:
The patent replaces bulky conventional sensor modules with fabric-based sensors that are knitted directly into the glove, substituting mechanical sensor assemblies with integrated textile-based sensing elements. This substitution dramatically reduces the size of sensing components while preserving detection functionality
Solution Approach 2:
The patent combines the sensor structure with the glove fabric structure by knitting sensors into the fabric itself, merging two previously separate components (glove and sensor) into a unified integrated structure, thereby reducing overall glove size
3Reliability
If conventional pressure sensors or inertial sensors are attached to the glove surface with circuit connections through flexible circuit boards, then hand gesture detection function is achieved, but wearing comfort deteriorates
Solution Approach 1:
The patent replaces rigid conventional sensors and flexible circuit boards with soft fabric-based sensors that are knitted into the glove, substituting hard mechanical components with flexible textile-based sensing elements. This substitution significantly improves wearing comfort while maintaining detection reliability
Solution Approach 2:
The patent uses fabric-based sensors that are flexible and thin, allowing the glove to conform naturally to the hand shape and movement. These flexible textile sensors replace rigid sensor modules, enabling natural hand gestures without restriction and improving overall wearing comfort
4Weight of moving object
If fabric-based pressure sensors are used to eliminate flexible circuit boards, then glove size is miniaturized and weight is reduced, but sensor information collection capability must be maintained
Solution Approach 1:
The patent employs composite fabric-based sensor structures that combine conductive materials with textile fibers, creating a material that simultaneously provides mechanical flexibility, electrical conductivity, and sensing capability. This composite approach maintains measurement precision while enabling miniaturization and weight reduction
Solution Approach 2:
The patent replaces conventional mechanical sensor assemblies with fabric-based sensing elements that collect pressure and inertial information directly through the textile structure, maintaining measurement precision through the piezoresistive and capacitive properties of the fabric composite materials
