Electric Kettle Power Connection Arc Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric kettles face durability issues due to the risk of arc discharge and spark generation between the power supply connection and receiving parts when the kettle body is not properly aligned with the power supply base, leading to reduced reliability and safety.
Innovation Solution
The electric kettle incorporates a detection system with first and second detection parts that ensure power supply is only connected when the kettle body is correctly positioned on the power supply base, and automatically disconnects the power supply when the kettle body is removed, reducing the likelihood of arc discharge and enhancing durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the power supply connection part and power receiving connection part remain connected when the kettle body is not on the power supply base, then the device can be quickly reconnected, but arc discharge and spark generation occur reducing durability
Solution Approach 1:
The detection part detects the position of the kettle body before the power supply connection is established. When the kettle body is not detected on the power supply base, the control part prevents power supply connection, thereby preventing arc discharge and spark generation before they can occur.
Solution Approach 2:
The detection part continuously monitors the position of the kettle body relative to the power supply base and provides feedback to the control part. The control part adjusts the power supply connection status based on this feedback, maintaining connection only when the kettle body is properly positioned, thus preventing harmful arcs while ensuring quick reconnection when needed.
2Productivity
If the power supply connection part and power receiving connection part are quickly connected without detection, then power supply is efficient, but arc discharge occurs causing wear on electrical contacts
Solution Approach 1:
The detection part performs a preliminary check of the kettle body position before enabling power supply connection. This preliminary action ensures that connection only occurs when properly aligned, preventing arc discharge and contact wear while maintaining efficient power supply during normal operation.
Solution Approach 2:
The system uses real-time feedback from the detection part to control the power supply connection. When the kettle body is correctly positioned, power supply is efficiently maintained; when mispositioned, the feedback triggers disconnection to prevent contact wear, thus balancing productivity and reliability.
3Reliability
If a detection system is added to detect kettle body position, then arc discharge is prevented improving durability, but device complexity increases
Solution Approach 1:
The detection part serves multiple functions: it detects the kettle body position, provides feedback to the control part, and enables the power supply connection only when properly positioned. By making the detection system multi-functional, the patent reduces overall device complexity while maintaining improved durability through arc discharge prevention.
Solution Approach 2:
The detection part, control part, and power supply connection mechanism are merged into an integrated system. The detection part and control part work as a unified control mechanism that automatically manages the power supply connection based on kettle body position, reducing the need for separate complex control circuits and improving durability with minimal added complexity.

AI summary
An electric kettle includes: a kettle body having a power receiving connection part and a heating part; a power supply unit including a power supply base having a power supply connection part, and a mounting unit; and a detection part. The detection part is configured to detect whether the kettle body is on the power supply base. The electric kettle is configured to supply power to the heating part via the power supply connection part and the power receiving connection part when the detection part detects that the kettle body is on the power supply base, and to stop power supply to the heating part when the detection part detects that the kettle body is not on the power supply base. The power supply connection part and the power receiving connection part are disconnected after the detection part detects that the kettle body is not on the power supply base.
