Battery for cleaner and cleaner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery designs for cleaners face challenges in compact configuration, efficient heat dissipation, and easy assembly, particularly due to protruding buttons and overlapping components that hinder space utilization and airflow.
Innovation Solution
The battery design features an asymmetric printed circuit board with a connector and board extension portions, allowing for compact configuration, efficient heat dissipation through airflow, and easy assembly by minimizing the protrusion of components and optimizing the layout to prevent overheating and improve durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the button is moved into the battery when operated, then the button can be operated to separate the battery, but a space for button movement must be provided causing the button to protrude outward
Solution Approach 1:
The button movement space is created in the width direction rather than the length direction. The first housing has a first width greater than the second width, creating a stepped structure where the button can move laterally within the housing without increasing the overall battery length. This dimensional reorganization allows button operation while maintaining compact battery dimensions.
2Ease of manufacture
If the printed circuit board is symmetrically arranged, then assembly is simplified, but heat dissipation is insufficient due to blocked airflow
Solution Approach 1:
The printed circuit board is asymmetrically arranged with its length direction aligned at an angle to the longitudinal axis of the battery housing. This asymmetric orientation creates airflow channels between the board and housing walls, allowing air to circulate and carry heat away from the battery cell and circuit board. The asymmetric layout simultaneously maintains assembly simplicity by using standard mounting techniques while solving the heat dissipation problem.
3Volume of moving object
If components are tightly packed to reduce space, then battery size is minimized, but heat accumulation occurs due to restricted airflow
Solution Approach 1:
Airflow channels are created in the width direction by making the first width greater than the second width of the housing. This stepped housing structure provides lateral space for air circulation without increasing the overall battery length. The airflow paths are established between the battery cell, printed circuit board, and housing walls, enabling heat dissipation while maintaining compact battery dimensions.
4Ease of operation
If the button protrudes outward to provide operation space, then the button can be easily operated, but the battery cannot be compactly configured
Solution Approach 1:
The button operation space is obtained by increasing the first width rather than the length of the housing. The button moves laterally within the housing in the width direction, allowing easy operation without the button protruding outward. This maintains the compact external shape of the battery while providing sufficient internal space for button movement and operation.

AI summary
The present disclosure relates to a cleaner including a battery, in which a battery includes a protruding portion protruding from a battery body to one side, and a button disposed on the protruding portion and configured to selectively fix the battery body to a battery accommodation portion, in which the button is easily operated to separate a handle, and the button does not protrude outward, such that the battery may be compactly configured.
