Vessel Lid Locking Mechanism for Leak-Proof Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vessel lids do not facilitate easy addition and removal while maintaining a secure seal, leading to potential spillage and inconvenience during liquid storage and transport.
Innovation Solution
A lid assembly comprising a base and a removably connectable lid with a locking mechanism using staggered L-shaped projections and a seal ring, allowing for a leak-proof seal and easy attachment/detachment by rotating the lid 30°, suitable for various vessel shapes and materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a lid is designed to be easily removable and addable, then the ease of operation is improved, but the sealing reliability may deteriorate
Solution Approach 1:
The lid assembly is divided into separate components: a lid body and a base with threading mechanisms. This segmentation allows the lid to be easily attached and removed while maintaining sealing through the threaded connection and gasket system.
Solution Approach 2:
A gasket or sealing element acts as an intermediary between the lid body and base, ensuring reliable sealing while allowing the lid to be easily attached and removed through the threaded mechanism.
2Reliability
If a locking mechanism is added to improve sealing, then the sealing reliability is improved, but the device complexity increases
Solution Approach 1:
The locking mechanism is merged with the threading structure of the lid base. The staggered L-shaped projections are integrated into the threaded connection system, so the locking function is achieved without adding separate complex components.
Solution Approach 2:
The L-shaped projections are positioned at specific locations (staggered arrangement) on the lid base to provide localized locking engagement with corresponding features on the vessel, ensuring sealing at critical points without requiring a complex overall structure.

AI summary
A lid assembly is connected to a vessel to provide a leak proof seal to prevent leakage of liquid from the vessel. The lid assembly includes a base and a removably connectable lid. The base has an open first end, an open second end and a sidewall. The sidewall defines a passageway which extends between the first and second end of the base. A plurality of projections are provided on an internal surface of the sidewall. The base is removably connected to the vessel. The removably connectable lid of the lid assembly has a stopper configured to be inserted into the open second end of the base. The stopper is provided with a plurality of external projections corresponding to the plurality of projections of the base such that the base and lid are moved between a locked and unlocked position using approximate thirty degree (30°) turns, respectively.
