Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cordless vacuum cleaners face challenges in providing adequate suction force and portability due to power requirements, as they often rely on battery packs that are not interchangeable across different devices and lack efficient charging and power management systems.
Innovation Solution
A cordless cleaning system featuring a rechargeable battery pack that is interchangeable across various devices, including stick vacuums, upright vacuums, and hand-held vacuums, with advanced power management and communication protocols to ensure optimal performance and extended battery life, allowing the battery pack to enter a 'sleep' mode for power conservation and adjust charging parameters based on device needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If battery packs are incorporated into vacuum cleaners to enable cordless operation, then portability is improved, but power output and suction force deteriorate
Solution Approach 1:
The battery pack is divided into multiple individual cells that can be connected in series to achieve required voltage levels. This segmentation allows the system to provide sufficient power output while maintaining the portability benefit of battery-powered operation, as each cell can be optimized for its specific function and combined to meet overall power requirements.
Solution Approach 2:
The system dynamically adjusts charging parameters and operating voltage based on the specific device requirements and battery state. By changing electrical parameters such as charging current, voltage levels, and power distribution, the system optimizes both power output for suction force and energy efficiency for portability.
2Reliability
If multiple different battery packs are used for different cleaning devices, then each device can have optimized power supply, but device complexity and user burden increase
Solution Approach 1:
The battery pack design incorporates universal communication interfaces and standardized electrical connections that allow a single battery pack type to interface with multiple different cleaning devices. The communication protocol enables the battery pack to automatically identify the connected device and adjust its parameters accordingly, providing device-specific optimization without requiring device-specific battery packs.
Solution Approach 2:
The system uses bidirectional communication between the battery pack and cleaning devices to exchange information about device power requirements, battery state, and charging parameters. This feedback mechanism allows the battery pack to automatically adapt its behavior to match the specific needs of each connected device, eliminating the need for multiple specialized battery packs while maintaining optimized power supply.
3Ease of operation
If the battery pack remains connected to devices during storage, then communication and power management are simplified, but energy is wasted and battery life is reduced
Solution Approach 1:
The battery pack implements periodic wake-up cycles during storage periods, transitioning between sleep mode and active mode at predetermined time intervals. During these periodic wake-up periods, the communication interface becomes active to check for connected devices and receive instructions. This periodic operation maintains simplified power management capabilities while minimizing energy consumption during extended storage periods between uses.
