Vacuum cleaning system including an electrical connection interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vacuum cleaners are limited in maneuverability and range due to the power cord, which can experience stress and disconnect during use, restricting access to certain areas.
Innovation Solution
An upright vacuum cleaner with an electrical connection interface that allows operation in both cordless and corded modes by connecting either a battery or a power cord, ensuring secure and standardized connections to prevent simultaneous power sources and reduce cord tension.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a power cord is connected to the vacuum cleaner, then the vacuum cleaner can operate continuously with unlimited runtime, but the maneuverability and range are limited by the cord length and the cord may experience stress and disconnect
Solution Approach 1:
The electrical connection interface is designed to accept multiple types of power sources (power cords and batteries) through a universal interface. This allows the vacuum cleaner to function in both corded and cordless modes, providing unlimited runtime when needed while maintaining maneuverability when using battery power. The interface standardization enables flexible power source selection without requiring separate connection mechanisms.
2Length of stationary object
If the power cord is made longer to extend the range, then the vacuum cleaner can reach more areas, but the cord experiences increased stress and is more prone to disconnection
Solution Approach 1:
The electrical connection interface includes built-in strain relief features and secure locking mechanisms that are预先 designed into the structure. These features prevent cord stress from transmitting to the connection point and ensure the cord remains securely connected even when extended, eliminating the need to choose between cord length and connection reliability.
3Adaptability or versatility
If the vacuum cleaner is designed to accept both power cords and batteries, then the versatility and adaptability are improved, but the electrical connection interface becomes more complex
Solution Approach 1:
The electrical connection interface uses a standardized universal design that accepts both power cords and batteries through the same connection mechanism. This universal interface maintains electrical simplicity while achieving power source compatibility, as both power sources connect through the same terminals and connection logic without requiring separate complex subsystems.

AI summary
A vacuum cleaning system includes an upright vacuum cleaner operable in a cordless mode and a corded mode. The upright vacuum cleaner includes a cleaning head for removing debris from a floor, a debris tube connected to the cleaning head for receiving the debris, and an electrical connection interface. The vacuum cleaning system also includes a battery and a power cord adapted for connection to the electrical connection interface. The upright vacuum cleaner operates in the cordless mode when the battery is connected to the electrical connection interface. The vacuum cleaner operates in the corded mode when the power cord is connected to the electrical connection interface.
