Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Older individuals and children face difficulties in applying toothpaste to a toothbrush due to mobility issues and identifying the correct toothpaste, leading to potential overflow from residual pressure in the toothbrush handle after use.
Innovation Solution
An electric toothbrush system with a detachable toothbrush head and handle, incorporating a control circuitry, chip-based identification for toothpaste and toothbrush authenticity, and a propeller mechanism for efficient toothpaste delivery, ensuring only genuine products are used and preventing overflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual toothpaste application is used, then device complexity is reduced, but ease of operation deteriorates for users with mobility issues
Solution Approach 1:
The toothbrush system automatically applies toothpaste to the brush head without user intervention. The power generation device activates the propeller mechanism that pushes toothpaste from the reservoir through the connection device to the toothbrush head, eliminating the need for manual application while assisting users with mobility limitations.
Solution Approach 2:
The system performs preliminary action by automatically delivering toothpaste to the brush head before the brushing process begins. The control circuitry activates the power generation device to push toothpaste onto the brush head in advance, so users do not need to manually apply it.
2Reliability
If chip-based identification system is implemented, then reliability of product authenticity is improved, but device complexity increases
Solution Approach 1:
The patent replaces manual visual inspection of toothpaste bottles with an automated optical scanning system. The scanning device reads identification codes or images on the toothpaste bottle and communicates authenticity information to the control circuitry, which then activates or deactivates the power generation device accordingly.
Solution Approach 2:
The control circuitry acts as an intermediary between the scanning device and the power generation device. It receives authentication information from the scanner, processes it to determine toothpaste authenticity, and then sends control signals to activate or deactivate the power generation device based on the verification result.
3Productivity
If power generation device is activated, then productivity of toothpaste delivery is improved, but harmful factors increase due to residual pressure overflow
Solution Approach 1:
The system incorporates feedback control where the control circuitry monitors the toothpaste delivery process and adjusts the power generation device operation accordingly. When the toothpaste reservoir is depleted or delivery is complete, the control circuitry deactivates the power generation device to prevent residual pressure from causing overflow, while maintaining efficient delivery during active use.
