Roll-on Applicator Oral Care Implement Clog-Free Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oral care implements with internal reservoirs for delivering auxiliary materials often face clogging issues, leading to inadequate delivery of oral care materials to the user's oral cavity, requiring time-consuming unclogging and inefficient application methods.
Innovation Solution
The design incorporates a roll-on applicator rotatably mounted within the oral care implement, allowing oral care materials to be delivered from an internal cavity to the user's oral surface through rotation, ensuring consistent and efficient application without clogging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pump or capillary action system is used to deliver oral care material from reservoir to head, then the oral care material can be delivered to the user's oral cavity, but the delivery mechanism or channels may become clogged
Solution Approach 1:
The patent extracts the oral care material delivery function from a complex pump or capillary system and implements it through a simple roll-on applicator that rotates to pick up and deposit material, eliminating the clogging issue associated with channels and pumps
Solution Approach 2:
The roll-on applicator acts as an intermediary between the reservoir and the user's oral cavity, picking up material through rotation and transferring it directly to the target surface without requiring clog-prone delivery channels
2Ease of operation
If a stationary applicator such as a pad or bristles is used to apply oral care material, then the material can be applied to the oral surface, but the application process becomes time-consuming and inefficient
Solution Approach 1:
The patent transforms the stationary applicator into a dynamic roll-on applicator that rotates during use, enabling continuous picking up and deposition of oral care material throughout the brushing motion, thereby improving application efficiency and eliminating time loss
3Adaptability or versatility
If internal reservoirs and delivery systems are added to toothbrushes, then auxiliary oral care materials can be delivered, but the device complexity increases and delivery mechanisms may fail
Solution Approach 1:
The patent extracts the complex pump and channel system from the toothbrush design and replaces it with a simple roll-on applicator mechanism that achieves the same material delivery function with minimal complexity
Solution Approach 2:
The roll-on applicator is self-actuating through the user's natural brushing motion, requiring no additional pumps, motors, or complex control systems to deliver the oral care material

Function Achieved in This Case
This solution enables effective and clog-free delivery of oral care materials, enhancing user experience by providing continuous application during brushing or oral hygiene routines.
Implementation Method 1
a roll-on applicator rotatably mounted to the body, such that the oral care material is delivered from the internal cavity to an exposed portion of the roll-on applicator due to rotation of the roll-on applicator
Implementation Method 2
the oral care material is delivered from the internal cavity to an exposed portion of the roll-on applicator
