Built-in Toothpaste Toothbrush Segmented Handle Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing integrated toothbrush and toothpaste designs face issues such as difficulty in holding the toothbrush due to soft handles, complex structures leading to unnecessary waste, and challenges in accurately dispensing and storing toothpaste, including risk of contamination and leakage.
Innovation Solution
A built-in toothpaste type toothbrush structure featuring a toothbrush casing, toothpaste inner tube, knob switch, and pushing structure that allows for controlled toothpaste delivery to the toothbrush head, incorporating a multi-sectional telescopic tube module or telescopic tube for precise toothpaste output and anti-contamination design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If toothpaste is stored in a soft container as the toothbrush handle, then the toothbrush and toothpaste can be integrated for convenient carrying, but the soft handle is difficult for users to hold while applying force
Solution Approach 1:
The toothbrush is divided into separate components: a hard handle for gripping, a toothbrush head, and a toothpaste container. This segmentation allows each component to have optimized properties - the handle provides structural support and grip comfort, while the toothpaste container is positioned separately to avoid interfering with handling.
Solution Approach 2:
The toothpaste container acts as an intermediary element that connects to the toothbrush head rather than forming the handle itself. This intermediary positioning allows the toothpaste storage function to be integrated with the toothbrush while maintaining a separate, ergonomically designed handle for comfortable holding.
2Adaptability or versatility
If the toothbrush structure is made complicated to integrate toothpaste storage, then the toothbrush and toothpaste can be combined, but the complicated structure requires discarding the whole toothbrush after a period of time causing waste
Solution Approach 1:
The toothbrush system is segmented into replaceable modules: a durable handle, a toothbrush head, and a toothpaste container. When the toothbrush head wears out, only the head needs replacement while the handle and container remain usable, reducing waste from discarding the entire toothbrush.
Solution Approach 2:
The design allows for selective replacement of consumable parts (toothbrush head and toothpaste) while retaining the non-consumable handle. This recovering principle extends the overall lifespan of the toothbrush system by separating disposable and reusable components.
3Volume of moving object
If the filler is covered in the brush cap, then the toothbrush appears compact, but it is difficult to know the amount of toothpaste extruded and the pressing component may be touched or pressed by mistake
Solution Approach 1:
The toothpaste container incorporates a dynamic dispensing mechanism with a movable pressing component that can be activated on demand. The container transitions from a closed state during storage to an active state during use, allowing controlled toothpaste extrusion while maintaining compactness when not in use.
Solution Approach 2:
The toothpaste container design provides visual feedback about the toothpaste level and dispensing status. Users can observe the amount of toothpaste remaining and the position of the pressing component, enabling better control over toothpaste extrusion while maintaining a compact form factor.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates convenient carrying and use while preventing toothpaste contamination and leakage, allowing for easy refilling and maintaining hygiene during travel.
Implementation Method 1
the pushing structure is driven to push a toothpaste along a moving path formed by the toothpaste storage handle and the toothpaste inner tube to a toothbrush head
Implementation Method 2
the knob switch is provided for controlling the communication of the toothpaste inner tube with the toothbrush casing to prevent contaminating the stored toothpaste

AI summary
A built-in toothpaste type toothbrush structure includes toothbrush casing, toothpaste inner tube, knob switch, toothpaste storage handle and pushing structure. The toothbrush casing includes a toothbrush head, an accommodating space, and an outlet and a socketing portion. The toothbrush casing is sheathed on the toothpaste inner tube and has a toothpaste channel inside, and the toothpaste storage handle is connected integrally with the toothpaste inner tube for storing toothpaste, and the pushing structure is installed in the toothpaste storage handle to push the toothpaste to the toothbrush head. Therefore, the knob switch can control the communication between the toothpaste inner tube and the toothbrush casing to avoid contaminating the toothpaste stored in the toothpaste inner tube, so that home and office users or students can carry and use the toothbrush for dental cleaning and oral hygiene conveniently.
