Toothbrush With Segmented Agent Housing For Potency Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing delivery implements, such as toothbrushes, face challenges in effectively housing and applying reactive agents like acids, bases, and medicaments, as these agents often lose potency over time and are difficult to transport in a cost-effective manner, making immediate application challenging.
Innovation Solution
A toothbrush design featuring distinct agent housing regions that prevent intermixing during storage but facilitate reaction and delivery during use, utilizing sealed structures that can erode or dissolve to release the agents, along with motorized movements to enhance mixing and application, such as bristles and capsules, allowing for efficient formation and application of a third agent on a desired surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If reactive agents are stored in conventional delivery implements, then transportation and storage are simplified, but the agents lose potency over time and are difficult to transport in a cost-effective manner
Solution Approach 1:
The toothbrush head is divided into separate agent housing regions (first and second regions) that physically isolate reactive agents from each other during storage. This segmentation allows each agent to be stored independently without degradation from premature reaction, maintaining potency over time while enabling convenient transportation of the complete system.
Solution Approach 2:
Multiple agents are pre-loaded into sealed housing regions within the toothbrush head before use. The sealing structures prevent intermixing during storage and transport, allowing the agents to be prepared in advance without losing potency. The reaction only occurs when needed, at the moment of delivery.
2Stability of the object's composition
If agents are housed separately to prevent intermixing, then agent stability is maintained, but the device complexity increases with multiple housing regions and sealing structures
Solution Approach 1:
Multiple agent housing regions are integrated into a single toothbrush head assembly, combining several functions (housing multiple agents, providing sealing, enabling delivery) into one unified structure. This merging reduces overall system complexity compared to using separate containers for each agent while maintaining the stability benefits of separate housing.
Solution Approach 2:
The toothbrush head serves multiple functions: it houses multiple different agents, provides sealing to prevent intermixing, facilitates controlled release through erosion/dissolution, and delivers the reacted mixture to the target surface. This multi-functionality reduces the need for additional separate components, simplifying the overall device while maintaining agent stability.
3Reliability
If sealed structures are used to prevent intermixing during storage, then agent purity is maintained, but the structures must erode or dissolve which may affect durability
Solution Approach 1:
The sealing structures are designed with specific material properties that change under different conditions: they maintain structural integrity and prevent intermixing during storage (normal conditions), but are designed to erode or dissolve when exposed to specific triggers (such as moisture or chemical reactions) during the delivery phase. This parameter change allows the structure to transition from a protective barrier to a release mechanism.
4Productivity
If motorized movements are added to enhance mixing and application, then delivery effectiveness is improved, but the device complexity and energy consumption increase
Solution Approach 1:
The system utilizes the natural movements of the user's mouth and the mechanical action of brushing to facilitate mixing and delivery of the agents. The toothbrush structure is designed to leverage these self-generated forces rather than requiring external motorized systems, achieving effective delivery while maintaining simplicity and avoiding additional energy consumption requirements.

AI summary
A reaction and delivery implement that includes a handle configured for user manipulation, a head having a plurality of agent housing regions, the first agent housing region housing a first agent and the second agent housing region housing a second agent, the first and second agents being different is described. The head is configured to facilitate both prevention of intermixing of the first and second agents in a storage position as well as reaction of the first and second agents through intermixing in a delivery position so as to produce and apply a third agent to a contacted surface when in the delivery position. The reaction and delivery implement may be an oral care implement such as a toothbrush. The implement may also be motorized and may be used with a wide array of reactions.
