Brewing Chamber Cover Safety for Hot Water Splash Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hot beverage preparation machines pose safety risks when the user opens the brewing chamber cover during water delivery, as hot water can splash and endanger the user.
Innovation Solution
Incorporation of a safety mechanism that squeezes or cuts off the water delivery line when the cover is opened, utilizing a safety member, pump, manometer, shutter, or channels to control water flow and prevent splashing, ensuring the user's safety by reducing or stopping water flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cover is opened during water delivery, then the user can access the brewing chamber, but hot water may splash and endanger the user
Solution Approach 1:
The safety member is positioned in advance to block the delivery line opening. When the cover is opened during water delivery, the safety member预先 blocks the opening to prevent hot water from splashing onto the user, while still allowing user access to the brewing chamber.
Solution Approach 2:
The safety member acts as an intermediary element between the delivery line and the user. It blocks the delivery line opening to intercept and contain the hot water flow, preventing direct contact between the user and splashing hot water while maintaining chamber accessibility.
2Object-affected harmful factors
If the safety member blocks the delivery line opening, then hot water splash is prevented, but water delivery may be obstructed
Solution Approach 1:
The safety member is designed to be movable rather than fixed. It can dynamically adjust its position - blocking the delivery line opening when the cover is opened during water delivery to prevent splashing, and moving away to allow normal water flow when the cover is closed and brewing is proceeding normally.
Solution Approach 2:
The safety member is positioned in advance at a location where it can block the delivery line opening. When the cover is opened during water delivery, it预先 blocks the opening to prevent hot water from splashing onto the user, while still allowing user access to the brewing chamber.
3Ease of operation
If the delivery line is made flexible to allow cover movement, then user access is enabled, but water flow control becomes difficult
Solution Approach 1:
The safety member acts as an intermediary element between the delivery line and the user. It blocks the delivery line opening to intercept and contain the hot water flow, preventing direct contact between the user and splashing hot water while maintaining chamber accessibility.
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
The safety mechanism effectively prevents hot water from splashing onto the user, maintaining beverage quality and freshness by ensuring the water is delivered safely and efficiently into the brewing chamber.
Implementation Method 1
a safety member (10) which squeezes the delivery line (9) when the cover (6) is in the open position
Implementation Method 2
a manometer (12) which is provided on the delivery line (9), and the control unit (13) which cuts off the water flow depending on the information received from the manometer (12)
Implementation Method 3
a pump (11) which draws water from the water reservoir (3) so as to flow through the delivery line (9)
Implementation Method 4
a shutter (14) which is provided on the delivery line (9), and the control unit (13) which closes the shutter (14) when the cover (6) is changed to the open position
