Solution Overview
Problem
Existing hand vacuum cleaners face challenges in providing a compact design that allows for larger and more powerful batteries while maintaining good weight distribution and longer run times.
Innovation Solution
The hand vacuum cleaner incorporates an energy storage member unit located within the handle and main body, with batteries arranged along the handle's axis, allowing for better weight distribution and increased power capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If larger batteries are provided in the hand vacuum cleaner, then power and run time are improved, but weight and size increase
Solution Approach 1:
The energy storage member unit is divided into multiple separate battery cells (first energy storage member, second energy storage member, third energy storage member) arranged in series along the handle axis. This segmentation allows the total power capacity to be distributed across multiple smaller units rather than one large battery, enabling better weight distribution and compact integration within the handle structure.
2Duration of action of moving object
If larger batteries are provided in the hand vacuum cleaner, then run time is improved, but device size increases
Solution Approach 1:
The battery cells are arranged in a longitudinal configuration along the handle axis (extending from first end to second end of the handle) rather than placing a single large battery in one location. This dimensional arrangement distributes the energy storage volume along the length of the handle, achieving the required run time capacity while maintaining a compact overall device size and balanced weight distribution.
3Stability of the object's composition
If batteries are arranged along the handle axis, then weight distribution is improved, but device complexity increases
Solution Approach 1:
Multiple battery cells (first, second, and third energy storage members) are combined into a single integrated energy storage member unit that is removably mounted as one assembly. This merging approach simplifies the overall device structure by treating the multi-cell arrangement as a single modular unit, reducing the complexity of individual component mounting while achieving improved weight distribution through the longitudinal arrangement of cells within the unit.
