Vacuum Cleaner Battery Airflow Cooling Without Separate Charging Station
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery-operated devices require separate charging stations with integrated cooling, increasing production costs and limiting cooling efficiency, as they often lack effective temperature control during operation.
Innovation Solution
Integrating a high-performance vacuum generator into a vacuum cleaner to control battery temperature by directing an air stream through the battery compartment, allowing for both cooling and warming, and incorporating a dual-function vacuum generator for efficient temperature management and dirt suction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a separate charging station with integrated cooling is used for battery-operated devices, then battery temperature control is achieved, but production costs increase and device portability is reduced
Solution Approach 1:
The patent combines the charging station functionality and battery cooling system into the vacuum cleaner housing itself. The vacuum cleaner includes a battery compartment that serves as an integrated charging station with air flow paths that direct cooling air to the battery during both operation and charging, eliminating the need for external cooling equipment.
2Volume of moving object
If small cooling fans are used in handheld devices, then device size is reduced, but cooling output becomes insufficient
Solution Approach 1:
Instead of relying on electric fans for cooling, the patent utilizes the vacuum cleaner's existing air suction and exhaust pneumatic system to provide cooling air flow to the battery. The vacuum generator creates pressure differentials that drive air through cooling channels around the battery, providing high cooling output without requiring additional fan motors.
3Temperature
If high-performance vacuum generator is integrated into vacuum cleaner, then battery temperature control is improved, but device weight increases
Solution Approach 1:
The vacuum generator serves dual functions: it provides the primary vacuum cleaning function by suctioning dirt through the filter, and simultaneously creates air flow through the battery compartment to cool the battery during operation and charging. This multi-functionality eliminates the need for separate cooling fans or air pumps, avoiding additional weight.
