Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sanitizing devices for electric shaving devices are bulky and heavy, making them inconvenient for travel, and pose a risk of eye injury from disinfecting light.
Innovation Solution
A compact sanitizing device with a base member and cover member that securely enclose the shaving unit, using disinfecting light to disinfect hair-cutting units, with a design that minimizes dimensions and prevents light escape, featuring a hinge mechanism and drainage system to facilitate safe and efficient disinfection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a sanitizing device is designed to provide both electrical charging function and disinfecting function, then the device can perform multiple functions, but the device structure becomes bulky and heavy
Solution Approach 1:
The patent extracts the charging function from the sanitizing device by providing a separate charging device with its own charging cavity. This allows the sanitizing device to focus only on disinfection, reducing its weight and complexity while maintaining multiple-functionality through the combination of the sanitizing device and separate charging device.
Solution Approach 2:
The patent segments the system into two separate devices: a sanitizing device for disinfection and a charging device for battery charging. This segmentation allows each device to be optimized for its specific function, preventing the sanitizing device from becoming bulky while still providing both functions through the combined system.
2Reliability
If disinfecting light is used to disinfect the shaving unit, then effective disinfection is achieved, but there is a risk of eye injury from the light
Solution Approach 1:
The patent converts the potentially harmful disinfecting light into a beneficial tool by enclosing it within a cover that has a light-emitting area. The cover acts as a controlled interface that allows the light to disinfect the shaving unit while preventing direct exposure to users' eyes, thus converting the harmful light into a safe and effective disinfection source.
Solution Approach 2:
The cover acts as an intermediary between the disinfecting light source and the user. It transmits the necessary light for disinfection through the light-emitting area while blocking direct exposure, serving as a protective mediator that enables effective disinfection without eye injury risk.
3Object-affected harmful factors
If the shaving unit is fully enclosed in the sanitizing device, then light escape is prevented, but the device structure becomes more complex
Solution Approach 1:
The patent uses a cover with a light-emitting area that acts as a flexible barrier to prevent light escape. The cover can be made of materials that block UV light while maintaining a relatively simple structure, avoiding the need for complex multi-layer enclosures while still effectively containing the disinfecting light.

AI summary
The invention relates to a sanitizing device (1) for disinfecting a shaving unit (7) of an electric shaving device (3) by means of disinfecting light. The sanitizing device has a base member (31) having a first cavity (43) for receiving a supporting member (15) of the shaving unit when the shaving unit is decoupled from a main body (5) of the shaving device. The sanitizing device further has a cover member (33) having a second cavity (71) for receiving, when the cover member is in a closing position relative to the base member, a hair-cutting unit (9a, 9b, 9c) of the shaving unit arranged on the supporting member. A light source (81a, 81b, 81c) is arranged in the cover member for irradiating the hair-cutting unit with the disinfecting light when the cover member is in the closing position wherein the first cavity and the second cavity fully enclose the shaving unit.
