Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bra garments use petroleum-based foam pad materials that are non-recyclable, toxic during production, and harmful to the environment, posing a need for sustainable and environmentally friendly alternatives.
Innovation Solution
The development of bra garments featuring cup portions made from Bio-Based Open-Cell Foam materials, primarily composed of sugarcane-based EVA and PE, which are recyclable, non-toxic, and provide both cushioning and support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If petroleum-based foam pad materials are used in bra garments, then structural support and cushioning are provided, but environmental harm and toxicity increase
Solution Approach 1:
The patent changes the chemical composition parameters of the foam material from petroleum-based to bio-based polymers (sugarcane ethanol, corn starch, soybean oil), transforming the material's origin while maintaining its functional properties of support and cushioning in bra garments
Solution Approach 2:
The patent creates composite foam materials by combining multiple bio-based polymers (EVA, PE, PU) with specific ratios to achieve the desired balance of support, cushioning, and environmental sustainability, replacing single-component petroleum-based foams
2Reliability
If petroleum-based foam pad materials are used in bra garments, then structural support is provided, but recyclability decreases
Solution Approach 1:
The patent changes the material origin parameter from fossil fuel-based to bio-based renewable sources, making the foam pads recyclable and environmentally sustainable while preserving their structural support function through optimized polymer composition
3Object-affected harmful factors
If bio-based open cell foam materials are used in bra garments, then environmental sustainability is improved, but material hardness and support capability must be optimized
Solution Approach 1:
The patent combines multiple bio-based polymers (EVA 20-40%, PE 30-50%, PU 10-30%) in specific ratios to create a composite foam material that achieves both environmental sustainability and adequate support capability through synergistic material properties
Solution Approach 2:
The patent applies different bio-based polymer compositions to different regions of the foam pad (higher EVA/PU content in high-support areas, higher PE content in cushioning areas) to optimize local mechanical properties while maintaining overall environmental sustainability

AI summary
A sustainable bra garment that includes first and second cup portions that are formed of one or more recycled flexible materials and first and second side wing panels that extend from the first and second cup portions, respectively, and having first and second cushioning support pads formed of a bio-based foam material having a very soft open cell structure. The first and second side wing panels are formed of one or more recycled flexible materials. First and second cushioning support pads are configured to be coupled with the first and second cup portions, respectively, each of the pads has front and back surfaces. The front surface of each pad has a generally convex shape and the back surface of each pad has a generally concave shape. Each of the pads is formed of a bio-based material, such as a sugar cane-based open cell foam material, that has hardness and density values that provide both cushioning and support to breasts of a wearer of the sustainable bra garment. The cushioning support pads may be used with a bra garment or with other garments such as swimwear and other apparel where bra support pads can be incorporated.
