Drawer Guide Rail Interlocking Mechanism to Reduce Hinge Wear
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drawer interlocking systems are prone to wear and damage due to repeated movement, leading to malfunction and inability to open drawers.
Innovation Solution
A drawer guide rail with an interlocking function featuring a guide rail assembly, interlocking components, including a fixing mechanism, toggle mechanism, and interlocking linkage members, which allow only one drawer to be opened at a time, enhancing structural stability and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the interlocking piece rotates along the hinge shaft with independent installation, then the interlocking function is achieved, but the hinge shaft and interlocking piece wear off or get damaged due to repeated movement
Solution Approach 1:
The patent merges the hinge shaft with the mounting plate by directly forming the hinge shaft on the mounting plate surface, eliminating the need for separate hinge shaft installation. This integration reduces the number of independent components and connection points, thereby reducing wear and damage risks associated with repeated movement of independently installed hinge shafts.
2Ease of operation
If the hinge shaft is independently installed on the mounting plate, then the interlocking piece can rotate freely, but the repeated movement causes wear and damage leading to stuck interlocking pieces
Solution Approach 1:
The hinge shaft is directly formed on the mounting plate surface as an integral structure, merging two previously separate components. This integration maintains the rotational functionality of the interlocking piece while eliminating wear at the connection interface, thereby improving the stability and reliability of the interlocking mechanism over time.
3Device complexity
If all drawers are controlled by one lockset, then the locking mechanism is simple, but all drawers must be closed before locking which reduces convenience
Solution Approach 1:
The patent divides the locking control into individual drawer units, with each drawer having its own interlocking piece that can independently engage or disengage. This segmentation allows any single drawer to be opened or closed without requiring all other drawers to be in a specific position, thereby improving operational convenience while maintaining relatively simple individual locking mechanisms.
