Detachable Battery Terminal Alignment for Handheld Vacuum Cleaners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery systems in handheld vacuum cleaners require disassembly for battery separation, occupy large volume, and have limited maximum voltage due to parallel battery cell arrangement, leading to instability in terminal contact and potential circuit board deformation.
Innovation Solution
A battery system with a detachable design featuring parallel alignment of battery terminals and anti-deformation ribs to stabilize contact and prevent circuit board deformation, allowing easy mounting and separation, and improved terminal reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a detachable battery structure is used to improve ease of operation and battery replacement, then the connection reliability between battery and main body deteriorates due to terminal contact instability
Solution Approach 1:
A connection guide structure comprising guide protrusions and guide grooves is introduced as an intermediary element between the battery and main body. The guide protrusions on the battery engage with corresponding guide grooves on the main body during insertion, automatically aligning the battery terminal with the main body terminal. This intermediary alignment mechanism ensures reliable electrical contact while maintaining the detachable nature of the battery structure, thus resolving the contradiction between ease of replacement and contact reliability.
2Duration of action of moving object
If battery capacity is increased to extend operation duration, then the weight of the battery increases
Solution Approach 1:
The battery system is designed with dynamic adaptability through a battery management unit that can optimize power distribution and a detachable structure that allows users to carry only the necessary battery capacity for each specific cleaning task. This dynamic approach enables the system to provide extended operation duration when needed while avoiding the constant weight penalty of carrying large-capacity batteries for all situations, thus resolving the contradiction between operation duration and battery weight.
