Innovation Solution
A cordless cleaning system utilizing a single, interchangeable battery pack with advanced control electronics that communicates with each device to ensure optimal performance, featuring a 'sleep' mode for power conservation and a 'wake' mode for efficient operation, and capable of powering a range of devices with varying voltage and current needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple cleaning devices are used to meet different cleaning needs, then cleaning versatility is improved, but device complexity and power management difficulty increase
Solution Approach 1:
The patent implements a universal battery pack design that can power multiple types of cleaning devices including upright vacuums, canister vacuums, and hand-held vacuums. The battery pack includes standardized electrical contacts and control electronics that automatically adapt to different device power requirements, eliminating the need for device-specific batteries and simplifying power management across the entire cleaning system.
Solution Approach 2:
The patent separates the power source (battery pack) from the cleaning devices, allowing the battery pack to be an independent, interchangeable component. This segmentation enables users to remove and replace the battery pack between different devices without integrating power systems into each device, thereby reducing overall system complexity while maintaining versatility.
2Use of energy by moving object
If battery packs are made larger to provide adequate power for cleaning devices, then power capacity is improved, but portability deteriorates
Solution Approach 1:
The patent implements dynamic power management through control electronics that monitor battery charge levels and adjust power delivery accordingly. The system includes wake/sleep modes that dynamically switch between high-power operation during cleaning tasks and low-power consumption during storage or idle periods, maximizing the effective power capacity of the battery pack without increasing its physical size or weight.
Solution Approach 2:
The patent employs parameter changes in battery chemistry and configuration to optimize the power-to-weight ratio. By adjusting electrical parameters such as voltage and current delivery based on the specific cleaning device being powered, the system extracts maximum power capacity from the battery pack without requiring proportional increases in battery mass, thereby maintaining portability.
3Loss of energy
If battery pack enters sleep mode to conserve power, then energy efficiency is improved, but wake-up response time increases
Solution Approach 1:
The patent implements preliminary action by maintaining a ready state or light sleep mode when the battery pack is inserted into a docking station or connected to a cleaning device. The control electronics perform preliminary checks and maintain minimal power to essential circuits, allowing for rapid transition to full power mode when needed, thus reducing wake-up response time while still achieving significant power savings compared to continuous operation.
