Solution Overview
Problem
Handheld vacuum cleaners typically have a single rated output voltage for their battery packs, limiting the user's ability to adjust the voltage applied to the suction unit, which restricts the range of suction power available for different cleaning tasks.
Innovation Solution
A collection system with a housing that includes a suction unit and an attachment unit for multiple battery packs with different rated output voltages, allowing users to select the appropriate voltage for the suction unit based on the chosen battery pack, thereby adjusting the suction power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single rated output voltage is used for the battery pack, then the device structure is simplified, but the suction power range is limited
Solution Approach 1:
The battery pack attachment unit is designed with universal compatibility to accept multiple types of battery packs with different rated output voltages. The attachment unit includes electrical contacts that can interface with different battery pack configurations, allowing the same vacuum cleaner housing to function with various power sources ranging from 18V to 36V, thus achieving multi-functionality without requiring multiple specialized devices
2Ease of operation
If multiple different types of battery packs are supported, then the suction power can be adjusted, but the device complexity increases
Solution Approach 1:
The system provides dynamic voltage selection capability where the user can choose the appropriate battery pack type based on the cleaning task requirements. The attachment unit is designed to dynamically adapt to different battery pack insertions, automatically recognizing the voltage level and configuring the electrical connection accordingly, making the voltage selection process as easy as simply attaching the desired battery pack
