Vacuum Cleaner Battery Button Nested in Protrusion for Compact Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaners face challenges with buttons that protrude outward, making it difficult to efficiently use space and complicating battery removal, especially in compact designs like handy and stick cleaners.
Innovation Solution
A battery design with a protrusion and button configuration that allows easy operation, where the button is positioned on a protrusion intersecting the battery insertion direction, featuring a hinge and hook mechanism for stable coupling and separation, minimizing outward protrusion and enhancing compactness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a button is disposed to protrude outward for easy operation, then ease of operation is improved, but device complexity and space efficiency deteriorate
Solution Approach 1:
The button is nested within a recessed space formed by the protrusion structure. When not in use, the button is concealed within the protrusion, creating a compact appearance. When pressed, the button can be easily operated through the protruding surface. This nesting approach resolves the contradiction by hiding the button during non-operation while maintaining accessibility during operation.
Solution Approach 2:
The button operation is moved from a planar surface to a three-dimensional protrusion structure. The button is positioned on the lateral surface of the protrusion, allowing operation in a direction perpendicular to the main battery surface. This dimensional change enables easy button access without requiring the button to protrude significantly from the overall battery envelope.
2Ease of operation
If a button is disposed to protrude outward for easy operation, then ease of operation is improved, but the compact form factor deteriorates
Solution Approach 1:
The button is nested within the protrusion structure, which itself protrudes from the battery body. This nested configuration allows the button to be accessible for operation while minimizing the overall protrusion distance from the battery's main envelope. The button does not extend beyond the protrusion's outer surface, maintaining a compact form factor.
Solution Approach 2:
The protrusion creates a localized area with different operational characteristics. The button is positioned on the lateral surface of the protrusion, allowing it to be easily pressed from the side while the rest of the battery maintains its compact, smooth form factor. This local differentiation enables easy button operation without compromising the overall compact design.
3Ease of operation
If space is allocated for button insertion to improve operation, then ease of operation is improved, but volume efficiency deteriorates
Solution Approach 1:
The button structure is merged with the protrusion, which also serves as a coupling feature between the battery and battery receiving part. The same protrusion that facilitates battery attachment also houses the button, eliminating the need for separate button mounting space. This merging of functions improves volume efficiency while maintaining ease of button operation.
Solution Approach 2:
The protrusion serves multiple functions: it acts as a mechanical coupling element for battery attachment, provides structural support, and houses the button mechanism. By making the protrusion multi-functional, the design eliminates redundant structures and optimizes the use of battery volume, allowing easy button operation without sacrificing volume efficiency.

AI summary
The present disclosure relates to a cleaner, more particularly, to a battery including a protrusion protruding toward one side from the battery body; and a button configured to selectively fix the battery body to the battery receiving part, and is capable of allowing easy operation of the button to release the handle, and allowing the button to be formed compact without protruding outward.
