Solution Overview
Problem
Existing handheld vacuum cleaners require disassembly to separate the power supply, have a large volume due to parallel battery cell arrangement, and provide limited maximum voltage to the suction motor, leading to inefficiencies in weight distribution and performance.
Innovation Solution
A handheld vacuum cleaner design with a battery housing positioned under the handle, allowing the battery to be separated and charged separately, featuring battery cells arranged in a zigzag pattern within the battery holder to reduce size and increase maximum charging voltage, along with a battery management unit and conductive plates for efficient power distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If battery cells are arranged in parallel on one layer, then the power supply structure is simple, but the volume occupied is large and the maximum voltage is limited
Solution Approach 1:
The patent transitions from a single-layer parallel arrangement to a multi-layer stacked configuration, utilizing the vertical dimension to arrange battery cells. This dimensional change allows the power supply to achieve higher voltage through series connection of layers while maintaining a compact footprint, directly resolving the contradiction between structural simplicity and volume efficiency.
Solution Approach 2:
The power supply is segmented into multiple independent battery cells arranged in series across different layers. Each layer functions as an independent unit that can be stacked vertically, allowing the system to achieve higher voltage through series connection while maintaining modularity and manageable complexity in the overall structure.
2Device complexity
If battery cells are arranged in parallel on one layer, then the arrangement is simple, but the maximum voltage supplied to the suction motor is small
Solution Approach 1:
By stacking battery cells vertically across multiple layers rather than arranging them in a single plane, the patent enables series connection of cells from different layers. This dimensional transition allows the system to accumulate voltage through the series arrangement while maintaining relative structural simplicity, thereby increasing maximum voltage output to the suction motor.
Solution Approach 2:
The battery system is divided into multiple discrete cells that can be connected in series across layers. This segmentation allows flexible configuration where cells from different layers are electrically connected in series, enabling the system to achieve higher voltage output while keeping the individual cell structure simple and manageable.
3Stability of the object's composition
If the battery is integrated into the cleaner body, then the structure is compact, but the power supply cannot be separated for charging
Solution Approach 1:
The power supply system is segmented into detachable battery cells that can be separated from the cleaner body. The battery cells are designed as independent removable units with connection interfaces, allowing users to easily detach and charge them separately while maintaining a stable and integrated structure when assembled, thus resolving the contradiction between structural compactness and charging convenience.
4Volume of moving object
If battery cells are closely arranged, then the volume is reduced, but the cooling performance deteriorates
Solution Approach 1:
The patent arranges battery cells in a multi-layer vertical stack rather than spreading them out horizontally. This dimensional reorganization allows the cells to be closely packed in the vertical direction while maintaining adequate spacing between layers for heat dissipation, achieving compact volume without compromising cooling performance through the three-dimensional configuration.
