Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated electronic vacuums are cumbersome due to the need for an electric outlet for cord connection and lack a strong vacuum motor, while portable handheld vacuums lack sensor detection and require manual operation, making them inefficient for wide-area cleaning.
Innovation Solution
A battery-operated vacuum system with a charging cradle that allows movement and repositioning, equipped with a sensor for automatic operation and a powerful motor, enabling efficient cleaning without an electric outlet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If automated electronic vacuum uses corded power from electric outlet, then continuous operation is ensured, but portability and ease of repositioning are reduced
Solution Approach 1:
The system dynamically switches between battery-powered portable mode and cradle-connected charged mode. The vacuum transitions from stationary corded operation to mobile battery-powered operation, allowing flexible adaptation between continuous operation and portability based on operational needs.
Solution Approach 2:
The rechargeable battery serves as an intermediary energy source between the electric outlet (cradle) and the vacuum motor. It stores energy when connected to the cradle and provides portable power when removed, resolving the contradiction between continuous operation and portability.
2Ease of operation
If portable handheld vacuum uses battery, then portability is improved, but vacuum motor strength is reduced
Solution Approach 1:
The battery is recharged in advance by connecting the vacuum to the charging cradle before portable use. This preliminary charging action ensures sufficient energy is stored to power the strong vacuum motor during mobile operation, resolving the contradiction between portability and motor strength.
Solution Approach 2:
The system changes the energy supply parameter from fixed corded power to mobile battery power. The rechargeable battery provides sufficient power output to maintain strong vacuum motor performance while enabling portability, as the battery can be recharged when needed.
3Device complexity
If handheld vacuum uses manual on/off operation, then device simplicity is maintained, but cleaning efficiency is reduced
Solution Approach 1:
The vacuum system performs self-service by automatically detecting movement near the inlet and turning on the vacuum motor accordingly. The sensor monitors the environment and autonomously activates cleaning when needed, eliminating the need for manual on/off operation while maintaining device simplicity.
Solution Approach 2:
The movement sensor provides feedback to the control circuit about environmental conditions. When movement (indicating presence of swept refuse) is detected, the circuit automatically activates the vacuum motor, creating a feedback-based automatic operation system that improves cleaning efficiency without adding complexity.
4Reliability
If automated vacuum requires outlet connection, then power supply reliability is ensured, but adaptability to different locations is reduced
Solution Approach 1:
The power supply mode dynamically adapts between cradle-connected charged mode (for reliability) and battery-powered portable mode (for location flexibility). Users can switch between these modes depending on whether the vacuum needs to be stationary or mobile, resolving the contradiction between reliability and adaptability.
Solution Approach 2:
The vacuum system serves multiple functions: it can operate as a stationary corded vacuum when connected to the charging cradle for reliable continuous power, and as a portable battery-powered vacuum when removed for location flexibility. This multi-functionality resolves the contradiction between power reliability and location adaptability.

AI summary
A system for vacuuming and charging includes a vacuum, a battery of the vacuum, a circuit for controlling the vacuum, a sensor connected to the circuit for detecting movement, and a cradle for charging the battery when the vacuum is connected to the cradle. The vacuum is moveable from the cradel and operational via the battery.
