Interlocking slide rail set combined with front cabinet lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional interlocking slide rail structures for cabinets are complex, inconvenient to install, and increase manufacturing costs due to the need for multiple components and intricate assembly processes, often resulting in unintended drawer movement and safety hazards.
Innovation Solution
An interlocking slide rail set combined with a front cabinet lock, featuring an inner rail, middle rail, interlocking sliders, and rods, which simplifies assembly by using a stopper and limiting holes to maintain interlocking sliders in a free gravity state, allowing sequential linkage and locking of drawers, and a link rod system for enhanced locking mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional interlocking structures use multiple components and intricate assembly processes, then the interlocking effect is achieved, but the device complexity and manufacturing costs increase
Solution Approach 1:
The patent combines the interlocking slider and the locking pin into a single integrated component. The locking pin is directly formed as an extension of the interlocking slider, eliminating the need for separate locking pins and reducing the number of parts. This merging approach maintains the interlocking effect while significantly simplifying the structure and reducing manufacturing complexity.
Solution Approach 2:
The interlocking slider is designed to perform multiple functions: it provides interlocking between adjacent drawers, serves as a locking mechanism through its integrated locking pin, and guides the drawer movement. By making the slider multi-functional, the patent eliminates the need for separate interlocking mechanisms and locking devices, thereby reducing device complexity while maintaining reliability.
2Reliability
If conventional interlocking structures use multiple components, then the interlocking effect is achieved, but the installation convenience deteriorates
Solution Approach 1:
By integrating the locking pin with the interlocking slider, the patent reduces the number of separate components that need to be assembled. Installers no longer need to separately install locking pins and interlocking sliders, as they come as a single pre-assembled unit. This significantly improves installation convenience while maintaining the interlocking effect.
Solution Approach 2:
The locking pin is pre-formed as an integral part of the interlocking slider during manufacturing. This preliminary action of combining components before installation eliminates the need for complex assembly operations at the installation site, making the installation process simpler and more convenient while ensuring the interlocking effect is already built into the component.
3Reliability
If conventional interlocking structures use intricate assembly processes, then the interlocking effect is achieved, but the manufacturing costs increase
Solution Approach 1:
The patent merges the locking pin and interlocking slider into a single component that can be manufactured in one process. This eliminates the need for separate manufacturing of locking pins and sliders, as well as the costly assembly operations required to combine them. The integrated design reduces manufacturing steps, lowers production costs, and maintains the interlocking effect.
Solution Approach 2:
The patent changes the manufacturing parameter from assembling multiple separate components to manufacturing a single integrated component. This parameter change in the manufacturing process eliminates assembly operations and reduces manufacturing complexity, thereby lowering production costs while ensuring the interlocking effect is built into the component design.
4Ease of operation
If drawers are allowed to slide out freely, then the ease of operation is improved, but safety hazards occur due to unintended movement
Solution Approach 1:
The patent incorporates a locking pin that automatically engages with the cabinet body when the drawer is pulled out beyond a certain point. This preliminary anti-action prevents the drawer from sliding out completely by providing automatic locking, thereby eliminating safety hazards associated with unintended drawer movement while still allowing normal opening operations.
Solution Approach 2:
The interlocking slider with integrated locking pin provides dynamic locking: the locking pin remains retracted during normal drawer opening, allowing free movement, but automatically engages with the cabinet body when the drawer exceeds a safe displacement. This dynamic behavior maintains ease of operation for normal use while preventing safety hazards through automatic locking.

AI summary
An interlocking slide rail set combined with a front cabinet lock includes the cabinet lock and plural interlocking slide rails. The cabinet lock is installed to a cabinet having plural drawers, and a rear end of the cabinet lock is connected to a driving portion. Each interlocking slide rail has an inner rail, a middle rail, an outer rail, plural slide assisting elements, a stopper, a pair of interlocking sliders and an interlocking rod, and the stopper is installed at a front end of the outer rail, and the two interlocking sliders are installed to the outer rails respectively, and two adjacent interlocking slide rail mechanisms are connected by the interlocking rod. During operation of using the cabinet lock or pulling any drawers, the interlocking sliders and the interlocking rods are linked to achieve an interlocking effect, thus simplifying or reducing components, facilitating installation, and lowering manufacturing costs.
