Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If polyurethane foam pads or formed parts are used to provide volume in garment, then voluminous appearance is achieved, but moisture absorption leads to odor and hygiene issues
Solution Approach 1:
The patent changes the material parameter from polyurethane foam to a three-dimensional mat of thermoplastic fibers. This material substitution fundamentally alters the moisture interaction properties, reducing moisture absorption while maintaining the voluminous appearance needed for the garment.
Solution Approach 2:
The invention uses a composite structure combining thermoplastic fibers arranged in a three-dimensional mat configuration. This composite material structure provides both the required volume and improved moisture resistance compared to traditional foam pads.
2Volume of moving object
If polyurethane foam pads or formed parts are used to provide volume in garment, then voluminous appearance is achieved, but strong thermal insulation causes discomfort and excessive sweating
Solution Approach 1:
The patent changes the material parameter from polyurethane foam to a three-dimensional mat of thermoplastic fibers. This material substitution fundamentally alters the thermal insulation properties, reducing excessive heat retention while maintaining the voluminous appearance needed for the garment.
3Volume of moving object
If polyurethane foam pads or formed parts are used to provide volume in garment, then voluminous appearance is achieved, but foam material is difficult to recycle creating ecological problems
Solution Approach 1:
The patent changes the material parameter from polyurethane foam to thermoplastic fibers. This material substitution fundamentally alters the recyclability properties, making the garment more easily recyclable while maintaining the voluminous appearance needed for the garment.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution reduces moisture retention, maintains a cooler climate, enhances hygiene, and promotes environmental sustainability by facilitating easy recycling.
Implementation Method 1
foams tend to absorb moisture, especially sweat and also condensed water that has been exhalated by the wearer
Implementation Method 2
foam pads and formed parts have a strong thermally insulating effect which leads to a very warm climate within the garment
