Water-Dissolvable Wearable Items for Environmental Disposal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wearable items, such as masks and gloves, contribute to environmental pollution due to their non-biodegradable materials and disposal challenges, particularly in high-traffic areas where they are frequently used.
Innovation Solution
Development of wearable items primarily made from water-dissolvable materials like polyvinyl alcohol, polyethylene glycol, and water-soluble paper, which can dissolve completely in water without leaving residues, allowing for safe and efficient disposal in existing infrastructure like toilets and sinks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If conventional non-biodegradable materials are used for wearable items, then durability and reusability are improved, but environmental pollution and disposal difficulties worsen
Solution Approach 1:
The patent changes the material parameter from non-biodegradable to water-dissolvable, transforming the end-of-life behavior of the wearable item. This allows the item to maintain durability during use while automatically degrading after disposal, resolving the contradiction between durability and environmental harm.
Solution Approach 2:
The patent embraces the disposable nature of the wearable item by using water-dissolvable materials that can be easily disposed of in water systems. This eliminates the need for complex recycling infrastructure and prevents long-term environmental accumulation, addressing the pollution issue while maintaining adequate service life.
2Ease of operation
If water-dissolvable materials are used for wearable items, then ease of disposal and environmental safety are improved, but material strength and durability may worsen
Solution Approach 1:
The patent applies different material properties to different functional requirements: the material exhibits high strength and integrity during the wear period, then transitions to rapid dissolution upon contact with water during disposal. This local quality differentiation in time resolves the contradiction between strength and ease of disposal.
Solution Approach 2:
The material dynamically changes its properties based on environmental conditions - maintaining structural integrity in dry conditions during use, then rapidly dissolving when exposed to water during disposal. This dynamic behavior resolves the apparent contradiction between strength and ease of disposal.
3Reliability
If single-use wearable items are provided in high-traffic areas, then public health safety is improved, but waste accumulation and litter problems worsen
Solution Approach 1:
The patent converts the potential harm of waste accumulation into a benefit by designing items that automatically dissolve in water systems. What would normally be a pollution problem (large quantities of discarded items) becomes an environmental safety feature, as the dissolution process eliminates litter while maintaining the necessary single-use safety protocol.
Solution Approach 2:
The patent utilizes hydraulic systems (water drainage systems) as the disposal mechanism. By designing items that dissolve in water, the patent leverages existing hydraulic infrastructure to automatically manage waste, converting the quantity of discarded items from a problem into a manageable flow through drainage systems.

AI summary
Embodiments include a wearable item comprising a water-dissolvable material that forms at least a majority of the wearable item. In examples, the wearable item corresponds to a covering for a portion of a person's body. In specific examples, the wearable item is in the form of a glove, mitten, protective mask or a hospital gown.
