Container Lid Locking Mechanism with Spring-Loaded Buckles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current container lid locking mechanisms are prone to damage due to direct contact with the side plates and bear the full weight of the lid when lifting, leading to reliability and durability issues, and are inconvenient to install and remove.
Innovation Solution
A container lid locking mechanism featuring a locking member with two pairs of position limiting structures and a reset mechanism, including a spring, that allows for secure locking and easy installation/removal by distributing the weight and reducing stress on the locking components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the locking member directly contacts the side plate to secure the lid, then the locking function is achieved, but the locking member is prone to damage due to direct pressing
Solution Approach 1:
A cushioning structure is introduced as an intermediary element between the locking member and the side plate. This cushioning structure absorbs the direct pressing force, preventing damage to the locking member while maintaining the locking function. The cushioning structure acts as a mediator that protects the locking member from direct contact stress.
2Ease of operation
If the locking member serves as the handle to lift the lid, then the lifting function is integrated, but the locking member bears full weight and is easy to be damaged
Solution Approach 1:
The lifting function is separated from the locking member by introducing a dedicated handle structure. The handle is specifically designed to bear the full weight of the lid during lifting operations, while the locking member is relieved of this weight-bearing responsibility and focuses solely on the locking function. This segmentation prevents damage to the locking member.
3Ease of manufacture
If the locking member is secured through plastic buckle for easy installation, then the ease of installation is improved, but the connection is inconvenient to install and disassemble
Solution Approach 1:
The connection mechanism between the locking member and the lid is designed to be dynamic and reversible. The locking member can be easily inserted into and removed from its mounting position on the lid, allowing for convenient installation and disassembly. This dynamic connection design maintains ease of manufacture while improving operational convenience.
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 mechanism enhances the reliability and longevity of the locking system by reducing the weight borne by the locking member during lid operation and simplifying installation and removal processes, ensuring smooth operation and prolonged service life.
Implementation Method 1
the reset member may keep the locking member in a locking position

AI summary
A container lid locking mechanism and a container. The container is provided with a base (3), side boards (2), and a lid (1). The locking mechanism comprises buckles (6), return members (7), recesses (8), openings (11), and locking holes (10). The recesses (8) and the openings (11) are located in the edge of the lid (1), and the locking holes (10) are located in the side boards (2). Each of the buckles consists of a buckle body and a tongue (61) extending out from the buckle body. The return members (7) can enable the buckles (6) to be kept in a locked position. The recesses (8) are used for accommodating the buckle bodies. Two pairs of limit structures are disposed on the buckles (6) and in the edge recesses (8) of the lid (1). When the locking mechanism locks, the pair of limit structures (13, 66) on the buckles (6) and the lid (1) are in a fitted state to limit the buckles (6). The tongue (61) penetrates through the opening (11) at the edge of the lid (1) and is fastened into the locking hole (10) in the side board (2). When the locking mechanism is in an unlocked state, the other pair of limit structures (16, 63) on the buckles (6) and the lid (1) are in a fitted sate to limit the buckles (6), and the tongue (61) exits from the locking hole (10) in the side board (2).
