Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pressure-operated electrical switches or parallel conducting strips are used, then movement detection function is provided, but device complexity increases and reliability decreases
Solution Approach 1:
The patent combines the support function and sensing function into a single integrated textile structure. The conducting textile yarns are woven directly into the support fabric, eliminating the need for separate sensor assemblies and complex mechanical switch dispositions. This merging of functions reduces device complexity while improving reliability through seamless integration.
Solution Approach 2:
The textile support structure serves multiple functions simultaneously: it provides mechanical support for the individual and acts as the sensing element for movement detection. The conducting yarns embedded in the textile perform both structural and electrical sensing roles, making the system more versatile and less complex than dedicated sensor systems.
2Measurement precision
If conventional sensor dispositions are used, then movement detection is achieved, but measurement precision of electrical conductivity variations is insufficient
Solution Approach 1:
The patent uses conducting textile yarns with metallic particles distributed throughout the textile structure, creating localized sensing zones where conductivity changes occur in response to specific mechanical deformations. This local quality enhancement allows precise measurement of conductivity variations at specific locations within the textile, improving both measurement precision and detection reliability.
Solution Approach 2:
The system detects movement by measuring changes in electrical conductivity parameters of the conducting textile yarns. When the textile deforms under load or during movement, the conductivity of the conducting yarns changes in a measurable way, providing precise detection of position and movement states through electrical parameter monitoring.
3Ease of manufacture
If conducting textile yarns with metallic particles are used, then integration with textile support is improved, but manufacturing complexity may increase
Solution Approach 1:
The patent creates a composite textile material by incorporating conducting yarns with metallic particles into the textile support structure. This composite approach allows the conducting elements to be integrated during the textile manufacturing process itself, such as during weaving or knitting, rather than requiring post-manufacturing assembly. This reduces overall manufacturing complexity while achieving seamless integration.
