Flexible Pressure Tab Release Mechanism for Latching Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices with detachable latching connections for body and cover parts are complex and costly to manufacture, requiring separate release mechanisms that complicate the design.
Innovation Solution
A simple and cost-effective design where a flexible pressure tab, cut out of the cover part, acts to release the latching hook, featuring a tab rib that engages with the latching hook, eliminating the need for additional release mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate sliding part or lever element is used for the release mechanism, then the latching connection can be released, but the device structure becomes complex and manufacturing cost increases
Solution Approach 1:
The release mechanism is merged with the cover part itself. The tab (11) is formed as an integrated flexible element directly from the cover part material, eliminating the need for separate sliding parts or lever elements. This integration maintains the release function while significantly simplifying the overall device structure and reducing manufacturing complexity
Solution Approach 2:
The cover part serves dual functions: it provides structural enclosure and simultaneously houses the release mechanism through its integrated tab. The tab's flexibility and geometric design enable it to self-effectuate the release function by engaging and disengaging the latching lugs (18, 19) without requiring external mechanical components
2Ease of operation
If multiple separate components are used for release mechanism, then release function is achieved, but manufacturing cost increases
Solution Approach 1:
Multiple functions (cover enclosure and release mechanism) are combined into a single integrated cover part. The tab (11) is formed as one continuous element with the cover part through standard molding processes, eliminating the need for separate components and assembly steps, thereby reducing manufacturing cost while maintaining ease of operation
Solution Approach 2:
The cover part is designed to perform multiple functions simultaneously: it provides the structural enclosure for the device and contains the integrated tab that serves as the release mechanism. This multi-functionality reduces the total number of components needed, simplifying both manufacturing and operation

Function Achieved in This Case
This design results in a reliable and inexpensive manufacturing process with a straightforward mechanical structure that ensures secure engagement and easy release of the cover part from the body part.
Implementation Method 1
a flexible pressure tab (11), which, when actuated, serves to release the rear grip of the latching hook (17)

AI summary
Disclosed is a device comprising a base part (2) and a top part (7) that can be joined to the base part (2) via a releasable locking connection (16). The locking connection (16) is provided with at least one catch (18, 19) that is attached to a locking web (20) and engages with a thrust bearing section (21) in a closed position, and a releasing mechanism which acts upon the locking connection (16) and causes the engagement of the or each catch (18, 19) to be canceled when being actuated. The locking connection (16) is also provided with a flexible pressure latch (11) which is recessed in the top part (7). A latch rib (15), under the effect of which the engagement of the or each catch (18, 19) is canceled, is molded onto the side of the pressure latch (11) facing the or each catch (18, 19), whereby a very simple and safe mechanical structure is obtained, resulting in a relatively low production cost.
