Vacuum cleaner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaners require disassembly of the cleaner body to replace or charge the battery, causing user inconvenience.
Innovation Solution
A vacuum cleaner design with a battery chamber and a rotatable battery cover that allows battery insertion and charging without disassembling the cleaner body, featuring a charging stand with an opening prevention rib to secure the battery cover during charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the battery assembly is provided inside the cleaner body, then the battery is protected and secured, but the cleaner body must be disassembled to replace or charge the battery, causing user inconvenience
Solution Approach 1:
The battery assembly is designed as a separate, detachable unit that can be independently removed from the cleaner body through a battery chamber, allowing users to replace or charge the battery without disassembling the entire cleaner body
Solution Approach 2:
The battery assembly is extracted from the internal structure and placed in a dedicated battery chamber with a removable cover, enabling external access and replacement of the battery while maintaining the integrity of the main cleaner body
2Ease of operation
If the battery cover is made rotatable for easy opening, then battery access is improved, but the battery cover may accidentally open during charging
Solution Approach 1:
The battery cover is designed to rotate between a closed position and an open position, providing dynamic accessibility while maintaining security when closed through the opening prevention mechanism
Solution Approach 2:
The opening prevention rib creates a preliminary constraint that prevents the battery cover from opening during charging operations, countering the potential accidental opening before it can occur

AI summary
A vacuum cleaner includes: a cleaner body including a battery chamber; a motor provided in the cleaner body to provide suction force; a battery detachably mounted in the battery chamber to provide electric power to the motor; a battery cover rotatably mounted in the cleaner body to open and close the battery chamber; and a charging stand on which the cleaner body is held and which includes an opening prevention rib located on a rotation path of the battery cover in a state in which the cleaner body is held on the opening prevention rib and preventing opening of the battery cover.
