Kettle Spout Guiding Board to Prevent Boiling Water Overflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional kettles experience overflow of boiled water due to bubbles forming near the bottom and entering the spout through holes, leading to water level rise and overflow.
Innovation Solution
A kettle design featuring a guiding board with a curved guiding segment that covers the through hole, preventing bubbles from entering and incorporating through bores in a communicating segment to allow water discharge without overflow, while the lid includes a temperature meter assembly for monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a through hole is provided in the body to communicate with the spout, then water can be discharged from the spout, but bubbles formed during boiling enter the spout through the through hole causing water overflow
Solution Approach 1:
The board is divided into two functional segments: a guiding segment that directs bubbles away from the through hole, and a communicating segment that allows controlled water discharge. This segmentation enables the structure to simultaneously achieve bubble diversion and water discharge without overflow.
Solution Approach 2:
The guiding board acts as an intermediary structure between the through hole and the spout. It mediates the flow of bubbles and water, allowing water to pass through the communicating segment while directing bubbles away from the through hole, thus preventing overflow.
2Temperature
If bubbles are allowed to enter the spout, then water can be heated and boiled, but the water level in the spout rises and causes overflow
Solution Approach 1:
The board segments the flow paths: the guiding segment handles bubble diversion while the communicating segment manages water discharge. This allows boiling to proceed normally while preventing bubble-induced overflow.
Solution Approach 2:
Different parts of the board have different functions: the guiding segment is positioned to intercept bubbles rising from the bottom, while the communicating segment is positioned to allow water discharge. This local differentiation of function enables selective control over bubble and water flow.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively prevents water overflow during boiling by directing bubbles away from the through hole and allowing controlled water discharge, enhancing usability and safety with temperature monitoring.
Implementation Method 1
bubbles are formed in the water near the bottom of the body. The bubbles may enter the spout through the through bores in the board and the through hole in the body
Implementation Method 2
water is poured into the body via the top opening, and the kettle is put above a heat source for boiling the water

AI summary
A kettle has a container and a guiding board. The container has a body. The body has an upper segment, a lower segment, and a through hole defined in the lower segment and having a top edge and a bottom edge. The guiding board is attached securely to an inner surface of the lower segment of the body, covers the through hole, and has a guiding segment. The guiding segment is attached securely to the inner surface of the lower segment of the body at a position below the bottom edge of the through hole, is curved in cross section, extends upward and toward the central line of the body, is free from forming a through bore, and has a top edge higher than the bottom edge of the through hole and lower than the top edge of the through hole.
