Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tongue cleaners fail to integrate mechanical cleaning with immediate liquid care effectively, leading to suboptimal user experience and hygiene results.
Innovation Solution
A tongue cleaner design featuring a handle with a brush head that includes an accommodation tank for beads, a movable hole, and a puncturing member that slides to release liquid nursing components, combined with a sliding connection and positioning structure for precise control, allowing efficient mechanical and chemical cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional tongue scraper or tongue brush is used, then the structure is simple, but the functions are single and cannot provide bactericidal, refreshing or nursing effects
Solution Approach 1:
The patent combines mechanical cleaning components (brush head with scraping plates) and liquid nursing components (bead container with puncturing mechanism) into a single integrated tongue cleaner device. This merging allows the device to provide both physical scraping and chemical nursing effects simultaneously, resolving the contradiction between functional versatility and structural simplicity.
Solution Approach 2:
The tongue cleaner is designed with multi-functionality to perform multiple tasks: mechanical scraping of tongue coating, delivery of liquid nursing components (bactericides, refreshing agents), and integrated storage. This universal design enables a single device to replace multiple separate oral hygiene products.
2Reliability
If liquid cleaning solution is pre-immersed in the brush head, then liquid care is provided, but the effective components are volatilized over time and the effect is difficult to endure
Solution Approach 1:
The liquid nursing components are pre-loaded into the bead container during manufacturing, but the puncturing mechanism is designed to release them only when needed during use. This preliminary preparation combined with controlled release prevents premature volatilization while ensuring the components are available when required.
Solution Approach 2:
The bead container acts as an intermediary storage system between the liquid nursing components and the tongue surface. The puncturing member serves as a controlled release mechanism that transfers the liquid from storage to application point only when activated, preventing premature exposure and volatilization.
3Ease of operation
If mouthwash is provided separately, then liquid cleaning is available, but the steps are cumbersome and cleaning and nursing cannot be synchronized
Solution Approach 1:
The patent merges the tongue cleaning function and liquid nursing function into a single integrated device. The brush head and bead container work together in one tool, allowing mechanical scraping and liquid application to occur simultaneously during a single oral hygiene routine, eliminating the need for separate mouthwash steps.
Solution Approach 2:
The integrated design allows continuous action where the brush head performs scraping while the puncturing member simultaneously delivers liquid nursing components. This continuous coordinated action eliminates interruptions between cleaning and nursing steps, saving time and improving operational convenience.
4Adaptability or versatility
If a puncturing member is added to release liquid components, then immediate liquid care is provided, but the device complexity increases
Solution Approach 1:
The puncturing member is designed as a movable component that can be actuated during use. The dynamic design allows the device to transition between a closed state (for storage) and an open state (for liquid release), providing versatility without requiring a completely complex static structure.
Solution Approach 2:
The puncturing mechanism is designed to be self-actuating through user action during normal tongue cleaning. The mechanical motion of using the tongue cleaner naturally triggers the puncturing and liquid release, eliminating the need for separate activation mechanisms or complex control systems.

AI summary
A tongue cleaner is provided, including a handle and a brush head. The brush head is composed of an outer brush plate and an inner brush plate. A scraping groove formed between the outer brush plate and the inner brush plate can efficiently clear a tongue coating. An accommodation tank and a movable hole are formed in the inner brush plate. A bead may be accommodated in the accommodation tank. A puncturing member is slidably mounted on the handle. An end thereof may enter the movable hole and extrude the bead to release an internal liquid component. In the present disclosure, a unique double-layer brush plate structure and a puncturing release mechanism of a built-in bead are used to implement synchronization between physical scraping and liquid nursing, thereby effectively improving a cleaning effect and user experience.
