Cordless surface cleaning apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cordless surface cleaning apparatuses, such as vacuum cleaners, face challenges in providing a longer runtime without compromising cleaning performance, especially for high-powered models that consume more power and deplete batteries quickly. Additionally, existing solutions, like trigger-activated cleaners, can be user-unfriendly.
Innovation Solution
A battery-powered surface cleaning apparatus with a sensing unit and controller that detects inactivity and transitions into power conservation modes to reduce power consumption, thereby increasing active cleaning time. This includes multiple power conservation modes based on elapsed inactivity time, which can turn off or reduce power to electrical components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If high power is supplied to electrical components for better cleaning performance, then cleaning performance is improved, but battery runtime is reduced
Solution Approach 1:
The system dynamically adjusts power consumption by transitioning between active mode (full power to electrical components) and power conservation mode (reduced power), allowing the cleaning device to adapt its performance based on real-time activity detection rather than operating at fixed power levels
Solution Approach 2:
The sensing unit automatically detects user activity and triggers the controller to switch between power modes without user intervention, enabling the system to self-regulate power consumption based on actual cleaning needs
2Ease of operation
If the cleaner remains on during pauses to maintain readiness, then ease of operation is improved, but power consumption increases
Solution Approach 1:
The system transitions from a static on/off state to a dynamic system that automatically detects pauses through the sensing unit and switches to power conservation mode during inactivity, then quickly returns to active mode when activity is detected, optimizing both readiness and energy efficiency
Solution Approach 2:
The sensing unit provides real-time feedback about user activity status to the controller, which automatically adjusts power consumption accordingly, creating a closed-loop system that responds to actual usage conditions

AI summary
A surface cleaning apparatus includes a battery powering one or more electric components. The surface cleaning apparatus can have a power conversation mode that is executed by a controller. The surface cleaning apparatus can be provided with a sensing unit configured to detect inactivity of the surface cleaning apparatus and the controller is configured to receive a signal from the sensing unit to execute the power conservation mode based on the signal.
