Pocket Toothbrush With Sliding Head and Integrated Toothpaste
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional toothbrushes are not easily portable and thus not readily available when needed, posing a challenge in maintaining oral hygiene on the go.
Innovation Solution
A foldable pocket toothbrush design with a case, head, rod, sliding ring, reservoir, and operating buttons that allows the toothbrush to be compactly carried and easily deployed for use with integrated toothpaste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional toothbrush is packaged in a standard container, then the toothbrush is protected and easy to store, but it cannot be carried in a pocket and is not readily available when needed
Solution Approach 1:
The toothbrush is nested within a compact case that houses both the brush and integrated toothpaste reservoir. The brush head, rod, and reservoir are arranged in a nested configuration where the brush fits inside the case containing the toothpaste, creating a pocket-sized unit that can be carried conveniently while maintaining protection and readiness for use
2Volume of moving object
If a toothbrush is made compact for pocket carrying, then portability is improved, but the complexity of deployment and storage mechanisms increases
Solution Approach 1:
The toothbrush employs dynamic mechanisms including a sliding ring that moves along the rod to deploy or retract the brush head, and buttons that trigger reservoir opening and toothpaste dispensing. These dynamic elements allow the compact structure to transform from a stored state to an operational state and back, maintaining pocketability while enabling full functionality through controlled movement and mechanical action
3Ease of operation
If toothpaste is integrated into the toothbrush case, then convenience of carrying both items is improved, but the device complexity and number of components increases
Solution Approach 1:
The invention merges the toothbrush and toothpaste into a single integrated unit. The reservoir containing toothpaste is incorporated within the case that also houses the brush, eliminating the need to carry separate toothpaste tubes or containers. This consolidation reduces the number of separate items to carry while providing all necessary oral hygiene components in one compact package
