Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing slide rail latch structures for cabinets are complex, leading to difficulties in manufacturing, assembly, and economic inefficiencies, along with operational defects such as frequent jamming and two-handed operation requirements.
Innovation Solution
A simplified slide rail latch structure featuring a slide rail fixing frame with a locking plate and latching fastener, comprising a locking base plate with perpendicularly bent sides, a latching fastener with hook and locking holes, and a flexible hook plate for easy assembly and dismantling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional slide rail latch structure with multiple components (shield, slide block, spring, fitting pin, hook) is used, then the latching function is achieved, but the device complexity increases and manufacturing becomes difficult
Solution Approach 1:
The patent combines multiple separate components (shield, slide block, spring, fitting pin, and hook) into a single integrated locking plate. The locking plate incorporates all these elements as unified structural features, eliminating the need for separate parts while maintaining the latching function. This merging directly reduces device complexity and assembly steps.
Solution Approach 2:
The locking plate serves multiple functions simultaneously: it provides shielding, contains the latching mechanism, houses the spring-loaded fitting pin, and includes the hook for securing to the level hole. This multi-functionality consolidates what were previously separate components into one universal element, reducing overall structure complexity.
2Reliability
If a traditional slide rail latch structure with multiple components is used, then the latching function is achieved, but the assembly process becomes time-consuming and difficult
Solution Approach 1:
By merging all latching components into a single locking plate, the assembly process is simplified from installing multiple separate parts to installing one integrated component. This dramatically reduces assembly time and eliminates the coordination required for multi-component installation.
Solution Approach 2:
The locking plate is pre-assembled with all its functional elements (spring, fitting pin, hook) already in position during manufacturing. This preliminary assembly of sub-components into a unified structure means that during final installation, no additional assembly steps are needed, reducing on-site assembly time.
3Reliability
If a traditional slide rail latch structure is used, then the latching function is achieved, but material waste increases and manufacturing efficiency decreases
Solution Approach 1:
The integrated locking plate design consolidates multiple components into one piece, reducing the total amount of material required. Fewer separate parts mean fewer materials to source, process, and assemble, thereby reducing material waste and improving manufacturing efficiency.
4Reliability
If a traditional slide rail latch structure with hook and spring mechanism is used, then the latching function is achieved, but operational defects such as frequent hook jamming occur
Solution Approach 1:
By integrating the hook directly into the locking plate structure rather than having it as a separate removable component, the design eliminates potential misalignment and jamming issues that occur with separate hook mechanisms. The unified structure ensures proper positioning and smooth operation.

AI summary
This present invention is an improved structure of slide rail latch for device cabinet, which includes: at least one slide rail fixing frame with a locking plate on its front end, and a locking base plate with upper and bottom locking ends on both sides. The locking base plate is composed of at least one latching hole, one locking pin and one latching fastener, which includes one latching base plate with upper and bottom latch bending side edges on both sides. This latching base plate is composed of at least one locking hook and locking hole which are correspondent with latching hole and locking pin respectively. The latch bending side edge includes a hook on its front end. Thus this invention will make the fixing frame of slide rail can be easily manufactured in all-in-one process, and more convenient and timesaving in assembly to improve economic benefit for assembly manufacturers.
