Rotating Battery Cover Sealing for Oral Cleaning Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oral cavity cleaning devices with battery-powered systems face challenges in easily replacing batteries, whether dry or rechargeable, due to design limitations that hinder quick and efficient battery swapping.
Innovation Solution
The oral cavity cleaning device incorporates a battery cover that is rotatably attached to the device body, featuring a seal member to secure the battery in place and allow easy detachment, with a terminal for electrical connection and an operation rib for manual switching between attachment and non-attachment states, facilitating simple battery replacement without additional tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the battery cover is made detachable for easy battery replacement, then ease of operation is improved, but sealing reliability deteriorates
Solution Approach 1:
The battery cover is designed to be rotatable rather than fixed, allowing it to switch between an attachment state (closed and sealed) and a non-attachment state (open for battery replacement). This dynamic mechanism enables easy battery replacement while maintaining sealing integrity when closed.
Solution Approach 2:
A seal member is introduced as an intermediary element between the battery cover and the device body. This seal member ensures reliable sealing when the cover is closed, while not interfering with the rotational movement needed for easy battery replacement.
2Ease of operation
If the battery cover is made rotatable for easy battery replacement, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The battery cover mechanism is segmented into distinct functional elements: the rotatable cover body, the seal member, and the operation rib. This segmentation allows each component to perform its specific function independently, simplifying the overall design while maintaining ease of operation.
Solution Approach 2:
The operation rib is designed to be engaged by a finger, allowing the user to manually rotate the cover without requiring any additional tools or complex actuation mechanisms. This self-service approach simplifies the mechanism while improving ease of operation.

AI summary
The present disclosure provides an oral cavity cleaning device capable of more easily replacing a battery. The oral cavity cleaning device according to the present disclosure includes a body having a housing space in which a battery is housed, battery cover configured to close an opening of the housing space, and seal member configured to seal a gap between battery cover and the body. Battery cover includes cover body rotatably attached to the body. Battery cover can be switched between an attachment state in which the opening of the housing space is closed and sealed with seal member and a non-attachment state in which sealing with seal member is released and battery cover can be removed from the body by rotating cover body. Cover body includes operation rib on which a finger can be hooked to switch between the attachment state and the non-attachment state of battery cover.
