Lever Latch Locking Mechanism for Filter Basket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking mechanisms for filter baskets are cumbersome and lack security against unintended opening, making them difficult to handle and secure.
Innovation Solution
A locking mechanism featuring a lever latch, slide, and spring-loaded counter-slider, which tilts to push the slide perpendicular to its axis, utilizing a spring force to securely engage and disengage the lid, ensuring easy handling and secure closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If resilient locking pins are used to secure the lid, then security against unwanted opening is improved, but handling becomes awkward and complex
Solution Approach 1:
The locking mechanism is divided into functionally independent components: a lever latch for secure locking, a slide for linear movement, and a spring-loaded counter-slider for automatic return. This segmentation allows each component to perform its specific function efficiently, resolving the contradiction between secure locking and easy handling.
Solution Approach 2:
The mechanism employs dynamic elements including a tiltable lever latch, a translatable slide, and a spring-loaded counter-slider that automatically returns to its initial position. These dynamic components enable smooth operation and easy handling while maintaining secure locking when engaged.
2Reliability
If a complex locking mechanism with multiple components is used, then security and reliability are improved, but device complexity increases
Solution Approach 1:
Multiple functional components (lever latch, slide, spring-loaded counter-slider) are merged into a single integrated locking mechanism assembly. The components work together in a coordinated manner, reducing the overall system complexity while maintaining reliable secure closure functionality.
Solution Approach 2:
The spring-loaded counter-slider automatically returns to its initial position after the lid is opened, eliminating the need for manual resetting of components. This self-service feature simplifies the operation and reduces the complexity of controlling multiple components.
3Ease of operation
If the locking mechanism uses a sliding projection pushed perpendicular to the axis, then ease of operation is improved, but the mechanism requires precise alignment and manufacturing
Solution Approach 1:
The mechanism incorporates built-in alignment features and tolerance compensation that cushion against misalignment issues before they affect operation. The slide and counter-slider are designed with features that guide proper alignment during assembly and operation, reducing the impact of manufacturing variations.

AI summary
The invention relates to a locking mechanism and a sieve basket with a lid 7, which includes the locking mechanism. A locking mechanism according to the invention comprises a lever 1, a slide 2, and a spring-loaded counter-slide 3, wherein the lever 1 is tiltable about a first axis and is connected to a sliding projection 4. The sliding projection 4 is designed such that, for an opening operation, when the lever 1 is lifted, it displaces the slide 2 perpendicular to the first axis, and the counter-slide 3 is thereby pressed by spring force against the direction of displacement of the slide 2.By lifting the lever 1 during the opening process of the locking mechanism, the lever 1 rotates about the first axis, and a sliding projection 4 of the lever 1 is pressed against a slider 2 by the tilting movement, so that the slider 2 performs a translational movement perpendicular to the first axis and thereby releases, for example, the locking mechanism of a lid 7, a door, a drawer, or the like. This ensures good handling of the locking mechanism according to the invention. In addition to the translational movement of the slider 2, a spring-loaded counter-slider 3 is pressed against the direction of movement of the slider 2.By means of a special shaping of the counter-slide 3, for example with an inclined section 3b shaped in the manner of a ramp, the translational movement of the counter-slide 3, in conjunction with a locking engagement 13 designed as a stop, for example the inwardly curved rim 13 of a container 6, can cause a force redirection, so that, for example, a lid 7 of a container 6 is lifted by the spring force of the counter-slide 3. This lifting effect results in a particularly secure separation of the locking mechanism from the counterpart, for example, the lid 7 with locking mechanism from the container 6, thus ensuring particularly advantageous and easier handling.
