Solution Overview
Problem
Existing vacuum jugs face issues with unintentional opening and complex assembly due to the design of their lids, leading to potential liquid leakage and operational complexity.
Innovation Solution
A vacuum jug design featuring a lid with an upper part fixed to the container and a lower part that is pivotably mounted, with a spring bias for easy operation and integral actuating element, along with stops to prevent incorrect operation, and a single annular seal for secure sealing, ensuring the lid can be reliably opened and closed without unintentional movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lid is mounted pivotably via a tilting edge and actuating lever, then the lid can be opened and closed for pouring, but the lid can be unintentionally pivoted into an open position causing liquid to escape
Solution Approach 1:
The lid is divided into an upper part fixed to the container and a lower part that pivots relative to the upper part. The lower part contains the pouring opening and is mounted pivotably on the upper part, allowing controlled opening while the fixed upper part prevents unintentional movement of the entire lid assembly.
2Reliability
If additional connecting elements are used to hold the lid assembly on the jug handle, then the lid can be securely attached, but the assembly becomes complex
Solution Approach 1:
The actuating element is designed integrally with the lower part of the lid, combining the lid structure and actuation mechanism into a single unified component. This reduces the number of separate parts and simplifies assembly while maintaining secure attachment to the container.
3Device complexity
If a single annular seal is provided in the area of the container opening, then the sealing structure is simplified, but adequate sealing must be maintained in both closed and open positions
Solution Approach 1:
The sealing system uses a single annular seal positioned in the area of the container opening that provides sealing in both closed and open positions. The seal is strategically placed to maintain contact with sealing surfaces regardless of the lower lid part's position, eliminating the need for separate sealing mechanisms for each state.
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
This design enhances handling by preventing unintentional opening, reducing the risk of liquid leakage and simplifying assembly, while maintaining a compact structure with fewer components and ensuring effective sealing during both closed and open positions.
Implementation Method 1
A spring can be provided between the upper part and the lower part, in particular a helical spring, which enables easy assembly and operation.
