Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pressure measurement test apparatuses for textile products, especially lower body clothing, are limited to static measurements and do not accurately capture pressure changes during body movements, failing to adequately evaluate comfort and sanitary properties.
Innovation Solution
A dynamic and static pressure measuring test apparatus with adjustable dimensions and moveable joints, equipped with sensors to mimic body movements, allowing for comprehensive pressure value measurement across different body positions and sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If static measurement apparatuses are used, then measurement simplicity is maintained, but measurement precision during body movements deteriorates
Solution Approach 1:
The patent applies the dynamics principle by transforming the static measurement apparatus into a dynamic system. The leg model is equipped with drive mechanisms that enable it to perform bending movements, lifting actions, and position changes, allowing the apparatus to simulate actual body movements during measurement. This dynamic capability enables accurate pressure measurement during movements while maintaining a structured, controllable system architecture.
Solution Approach 2:
The patent uses an intermediary approach by introducing a controllable leg model as a mediator between the measurement system and the actual human body. This leg model serves as a test subject that can be precisely controlled and instrumented with sensors, allowing indirect but accurate measurement of pressure changes during movements without requiring direct measurement on human subjects.
2Adaptability or versatility
If fixed-dimensional apparatuses are used, then manufacturing simplicity is maintained, but adaptability to different body sizes deteriorates
Solution Approach 1:
The patent implements adjustable dimensions through drive mechanisms that enable the leg model to change its length, circumference, and joint angles dynamically. This allows the same apparatus to adapt to different body sizes (child, adult, large adult) by programmatically adjusting the leg model's configuration, eliminating the need for multiple fixed-size apparatuses.
Solution Approach 2:
The patent applies parameter changes by enabling continuous adjustment of the leg model's physical parameters including length, diameter, and joint angles through controlled drive mechanisms. These parameter adjustments allow the apparatus to accommodate various body types and sizes while maintaining a single standardized device design.
3Adaptability or versatility
If unidirectional expansion is implemented, then size adjustment capability is improved, but measurement region coverage deteriorates
Solution Approach 1:
The patent overcomes the limitation of unidirectional expansion by implementing multi-axis drive mechanisms that enable the leg model to perform not only circumferential expansion but also bending movements, lifting, and position changes. This dynamic capability allows comprehensive coverage of different measurement regions (calf, thigh, knee, ankle) while maintaining size adjustment functionality.
