Travel Toothbrush With Integrated Paste Compression Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional toothbrushes are cumbersome for travel due to the need to carry both the toothbrush and a separate tube of toothpaste, making portability inconvenient.
Innovation Solution
A self-contained toothbrush design with a handle, neck, and toothbrush head that includes an interior channel and a compression mechanism to extrude toothpaste from a refillable packet, eliminating the need for a separate toothpaste tube.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If toothpaste is stored in a separate tube, then toothpaste can be easily replaced and refilled, but portability becomes cumbersome and inconvenient
Solution Approach 1:
The patent combines the toothbrush and toothpaste storage functions into a single integrated unit. The toothbrush handle contains an internal cavity that houses a toothpaste cartridge, eliminating the need to carry separate toothpaste tubes. This merging of functions directly resolves the contradiction by maintaining toothpaste replaceability while significantly improving portability.
Solution Approach 2:
The toothpaste cartridge is nested within the toothbrush handle cavity. The cartridge can be inserted and removed independently from the handle, allowing for easy replacement while maintaining a compact, single-unit structure during travel. This nesting approach enables both easy refilling and improved portability.
2Stability of the object's composition
If toothpaste is stored in a rigid container, then structural stability is maintained, but toothpaste cannot be easily dispensed
Solution Approach 1:
The toothpaste cartridge incorporates a flexible diaphragm that can be compressed dynamically to dispense toothpaste. The diaphragm transitions from a relaxed state to a compressed state when actuated, enabling easy toothpaste dispensing while the overall cartridge structure remains stable within the rigid handle cavity.
Solution Approach 2:
The patent changes the physical state of the toothpaste container from rigid to flexible by using a compressible diaphragm. This parameter change allows the container to transition between stable storage and active dispensing modes, resolving the contradiction between structural stability and ease of dispensing.
3Ease of manufacture
If toothbrush and toothpaste tube are carried separately, then each component can be optimized independently, but overall device complexity increases
Solution Approach 1:
By merging the toothbrush and toothpaste storage into a single integrated unit, the patent reduces overall device complexity despite maintaining independent component optimization. The handle cavity and cartridge are designed as separate manufacturable parts that assemble into a unified structure, allowing independent optimization while simplifying the user experience.
