Powered Toothbrush Case with Light-Transmissive Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Travel toothbrushes, especially powered ones, face challenges in storage and power management, leading to inadvertent power drain and hidden charging status issues due to inadequate storage solutions that fail to communicate the toothbrush's power or charging condition without opening the case.
Innovation Solution
A storage case with a light-transmissive cover that allows the indicator light from within to be visible, ensuring the user can confirm the toothbrush's charging status without opening the case, while also providing separate storage for the toothbrush and its peripherals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the cover is made opaque to protect the toothbrush interior, then protection and privacy are improved, but the ability to detect charging status is worsened
Solution Approach 1:
The cover transitions from being uniformly opaque to having differentiated optical properties: most of the cover remains opaque for protection, while specific localized regions (windows) are made light-transmissive to allow indicator light visibility. This resolves the contradiction by applying different quality characteristics to different parts of the same component.
Solution Approach 2:
The cover utilizes optical property changes by incorporating light-transmissive regions that allow the indicator light to pass through. The material properties of the cover are changed locally to enable light transmission in specific areas while maintaining opacity in others, allowing users to detect charging status without opening the case.
2Strength
If the storage case is made sturdy to protect the toothbrush, then durability is improved, but the complexity of the system is worsened due to additional peripherals
Solution Approach 1:
The storage case merges multiple functions into a single device: it provides mechanical protection for the toothbrush, stores peripheral items (batteries, chargers, travel adapters), and includes an integrated indicator system to monitor charging status. By combining these previously separate functions into one unified case, the solution reduces the number of separate peripherals the user must carry and manage.
Solution Approach 2:
The storage case is designed as a multi-functional universal container that can accommodate the toothbrush in various states (stored, charging, traveling) and simultaneously hold multiple types of peripherals. The case serves as protection, storage, charging station, and status monitor all in one device, eliminating the need for separate specialized items for each function.
3Loss of information
If the cover is made light-transmissive to show indicator light, then visibility of charging status is improved, but protection from external impact is worsened
Solution Approach 1:
The cover is designed with differentiated local properties: the majority of the cover surface remains opaque and sturdy for impact protection, while specific localized windows or regions are made light-transmissive to allow indicator light visibility. This selective application of different material properties resolves the contradiction between protection and visibility.

Function Achieved in This Case
The solution ensures the user can discreetly and quickly verify if the toothbrush is being charged, preventing power drain and ensuring readiness for use, while maintaining the toothbrush's components securely and organized during travel.
Implementation Method 1
the cover substantially obfuscates the interior but is sufficiently light-transmissive to communicate the presence of an indicator from within the interior
