Push-button locking cup lid and thermos cup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing thermos cups with double sealing valves can cause accidental discharge of steam or water when the button is pressed by mistake, leading to potential burns and are not suitable for carrying in a handbag due to the risk of unintended operation.
Innovation Solution
A push-button locking cup lid with a double sealing valve structure featuring a button rod, water outlet valve rod, steam outlet valve rod, and spring mechanisms that ensure asynchronous operation, combined with a slider switch and blocker to prevent accidental presses, allowing safe and controlled discharge of steam and water.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a button rod is used to open valves for discharging steam and water, then the operation convenience is improved, but the risk of accidental discharge and user injury increases
Solution Approach 1:
The patent applies preliminary anti-action by designing a locking mechanism that prevents the button rod from being pressed accidentally. The slider switch engages with a blocking groove on the button rod to lock it in place before use, and must be deliberately disengaged by the user to enable valve operation. This preliminary locking action counteracts the potential harmful effect of accidental pressing.
Solution Approach 2:
The patent introduces a slider switch as an intermediary component between the user's finger and the button rod. This intermediary mechanism requires deliberate user action to disengage the lock, serving as a mediator that prevents direct and accidental contact with the button rod while still allowing intentional operation when needed.
2Device complexity
If steam and water are discharged simultaneously through a single valve, then the device complexity is reduced, but the user safety deteriorates due to high-temperature steam discharge
Solution Approach 1:
The patent applies segmentation by dividing the discharge function into two separate valves: a steam discharge valve and a water discharge valve. Each valve is controlled by the button rod independently, allowing steam and water to be discharged separately. This segmentation prevents hot steam from mixing with cooler water and reduces the risk of steam burns to users.
Solution Approach 2:
The patent implements preliminary action by designing the valve mechanism to discharge steam first before water. When the button rod is pressed, the steam discharge valve opens first to release pressure and temperature, followed by the water discharge. This preliminary steam discharge action prepares the system for safe water discharge afterward.
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 solution ensures safe operation by locking the button rod, preventing accidental leakage and ensuring steam is discharged before water, thus enhancing user safety and experience by preventing burns from high-temperature steam.
Implementation Method 1
two ends of the front spring are fixedly connected to an inner front side wall of the spring mounting box and the position limiting pin respectively; two ends of the rear spring are fixedly connected to an inner rear side wall of the spring mounting box and the position limiting pin respectively
