Solution Overview

Problem

Existing cleaners face challenges with buttons that protrude outward, making efficient use of space difficult and complicating battery removal, particularly in compact designs like handy and stick cleaners.

Innovation Solution

A battery design featuring a button positioned on a protrusion that slides forward for coupling and includes a hinge and hook mechanism, allowing easy operation and compact integration without outward protrusion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a button is disposed at a rear center of a battery to allow separation, then the user can separate the battery from the cleaner, but the button protrudes outward causing inefficient space utilization

Engineering Contradiction:
Improvebattery separation operationVSAvoidbattery space utilization
Core Design Contradiction:
Ease of operationVSVolume of moving object

Solution Approach 1:

The button is nested within a protrusion structure on the battery body. When the button is pressed, it moves into the protrusion space, allowing the button mechanism to be contained within the battery's external dimensions rather than protruding outward, thus resolving the space utilization issue while maintaining operational functionality

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The button mechanism utilizes the depth dimension by moving into the protrusion rather than extending in the lateral dimension. This dimensional transition allows the button to be operated effectively while keeping the battery's external profile compact and space-efficient

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If a button mechanism is implemented for battery separation, then the user can easily remove the battery, but the button requires insertion space causing it to protrude outward

Engineering Contradiction:
Improvebattery removal convenienceVSAvoidbattery compact form
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The button is nested within the protrusion structure, allowing the button mechanism to be housed within the battery body rather than extending outward. This maintains the compact form factor while enabling easy battery removal through button actuation

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The button structure is merged with the protrusion feature, combining the operational element with the structural feature into a single integrated component. This eliminates the need for separate button housing and reduces overall space requirements

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The present disclosure relates to a cleaner including a battery, 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, and a cleaner including the same.
