Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional toothpaste tubes fail to control the amount used for brushing, leading to health risks from excessive ingestion, environmental waste, and inefficiency, as they do not prevent accidental swallowing and cause mess.
Innovation Solution
Dissolvable toothpaste droplets with a membrane formed from film strip technology that embeds into toothbrush bristles, providing a pre-measured amount and dissolving with water or saliva for easy use, reducing waste and preventing ingestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional toothpaste tubes are used, then toothpaste can be stored and transported conveniently, but the amount used for brushing cannot be controlled leading to excessive ingestion and health risks
Solution Approach 1:
The toothpaste is divided into individual single-use droplets, each containing a pre-measured safe amount (e.g., 0.25 mL). This segmentation eliminates the ability to overuse toothpaste while maintaining convenient storage and transport of multiple small units.
Solution Approach 2:
The correct amount of toothpaste is pre-measured and sealed in each droplet before use. This preliminary action ensures that users cannot accidentally ingest excessive amounts, as each droplet contains only the safe, recommended quantity.
2Productivity
If traditional toothpaste tubes are used, then toothpaste can be dispensed continuously, but waste and mess occur due to inability to control the amount used
Solution Approach 1:
Toothpaste is segmented into discrete droplets that match the optimal brushing amount. This prevents waste from squeezing out excess toothpaste while maintaining efficient dispensing by simply placing one droplet on the brush.
Solution Approach 2:
The invention uses disposable single-use droplets that are discarded after one application. This eliminates waste from leftover toothpaste in tubes and removes the need for cleaning dispensing mechanisms, improving overall efficiency.
3Reliability
If traditional toothpaste tubes are used, then toothpaste can be stored in a sealed container, but environmental cost increases due to extended degradation time of empty tubes
Solution Approach 1:
The invention replaces persistent plastic tubes with biodegradable droplet wrappers that decompose rapidly (e.g., within weeks). This maintains product protection during use while dramatically reducing environmental impact after disposal.
Solution Approach 2:
The degradation time parameter of the packaging material is changed from years (traditional plastic tubes) to weeks (biodegradable droplet wrappers). This parameter change maintains storage protection during the product's lifecycle while eliminating long-term environmental persistence.
4Quantity of substance
If single use chewable capsules containing toothpaste are provided, then the amount can be controlled, but the capsules cannot hold onto the brush and require adaptation of the toothbrush kit
Solution Approach 1:
Instead of modifying the toothbrush to hold capsules, the invention inverts the approach by designing the droplet to attach directly to the brush bristles. This simple geometric design (asymmetric shape with flat base) requires no modification to existing toothbrushes.
Solution Approach 2:
The droplet is designed with asymmetric local quality - a flat base area for attachment to bristles and a rounded top for containing toothpaste. This localized structural feature enables brush attachment without requiring complex modifications to the toothbrush kit.

AI summary
A droplet for delivering toothpaste to a user can be provided. The droplet can include a dissolvable outer membrane defining a volume with toothpaste inside the volume. The outer membrane can be formed from dissolvable film strip technology and include a tail or corner portion, which is configured to be embedded into the bristles of a toothbrush. In one aspect of this embodiment, the outer membrane of the droplet can form a pillow-like shape. The droplet further can include one or more extensions coupled to the outer surface of the outer membrane, where the one or more extensions can have a triangular shape, a barb shape or the like. In one aspect of this embodiment, the droplet further can include a logo, a cartoon character, a word or the like printed on the outer membrane. The plurality of extensions can form irregularities on the outer surface of the body section of the outer membrane.
