Solution Overview

Problem

Conventional oral care systems require separate toothbrushes and kits for applying oral care agents, leading to space inefficiency, forgetfulness, and inefficiency in application, especially during travel, as they are not conveniently portable and apply agents one tooth at a time.

Innovation Solution

A toothbrush design with an applicator fluidly coupled to a store of oral care material, featuring a depression in the handle with a concave applicator surface that matches teeth contours for simultaneous application, and a cover that alters between storage and use states to protect the material and facilitate easy use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional separate toothbrush and oral care agent kit are used, then storage space is required for multiple devices, but portability and convenience are reduced

Engineering Contradiction:
Improveintegration of oral care functionsVSAvoidnumber of separate devices
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the toothbrush and oral care agent dispensing system into a single integrated device. The toothbrush handle incorporates a reservoir for storing oral care material and an applicator for dispensing it, eliminating the need for separate toothbrush and oral care agent kit, thus improving portability while maintaining multiple oral care functions

Inventive Principle:
Principle #5Merging (Combining)

2Productivity

If conventional oral care agent application is used, then application to single tooth at a time is achieved, but time consumption and effectiveness are reduced

Engineering Contradiction:
Improveapplication speedVSAvoidtime for oral care agent application
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The applicator transitions from point-contact (single tooth) to surface-contact (multiple teeth) by using a contoured surface that matches the facial surfaces of multiple teeth. This dimensional change from applying to one tooth at a time to simultaneously applying to multiple teeth dramatically increases application speed and effectiveness

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Ease of operation

If oral care material is stored in separate container, then material protection is achieved, but ease of use and portability are reduced

Engineering Contradiction:
Improveconvenience of oral care material applicationVSAvoidnumber of separate components
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The reservoir containing oral care material and the applicator for dispensing it are integrated into the toothbrush handle as a single unit. This merger maintains material protection through the enclosed reservoir while dramatically improving ease of use and portability by eliminating the need to carry separate containers and application devices

Inventive Principle:
Principle #5Merging (Combining)

4Adaptability or versatility

If conventional travel oral care setup is used, then oral care treatment is possible, but portability during travel is compromised

Engineering Contradiction:
Improveportability for travelVSAvoidconvenience during travel
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

By integrating the toothbrush, oral care material reservoir, and applicator into one compact device, the patent creates a travel-friendly oral care solution that maintains full functionality. Users can carry this single integrated device during travel, eliminating the bulk of multiple separate products while retaining the ability to perform complete oral care routines including both brushing and oral care material application

Inventive Principle:
Principle #5Merging (Combining)
